VIEWPOINT Driving engine oil performance
H
ave you ever taken a moment to think about what kind of testing goes into the products that go into your equipment? It’s certainly not the first thing to come up around the water cooler. I admit that it’s not the first thing I think of when it comes to engine and gear oils either. We hear from a lot of lubrication operations when new products come out, of course, and they all assure that their products have been tested under the most rigorous conditions, but we rarely stop and look into what those conditions are. Which is why I admit to a little confusion finding myself on the inside of a road racing course recently as part of a media event. As it turns out, there’s a good reason for the setting – but more on that in a moment. I was visiting with a team of experts from Petro-Canada Lubricants, which has recently released several new heavy-duty engine oil and transmission fluid offerings formulated under American Petroleum Institute CK-4 and FA-4 standards. Any time that new standards are introduced and new products are brought to market, there’s understandably going to be concerns from equipment owners that any positive benefits – longer intervals between oil drains, better fuel efficiency, and so forth – are going to come with negatives such as increased wear on the engines. That’s where testing and work with customers comes in, to ensure that these products will deliver what they need to without causing any problems. For Petro-Canada Lubricants, that has included a variety of tests, both on-road and off. The company worked with an Alberta hauling company, Boots Transport, to trial the new FA-4 product and show that it would reduce costs overall while providing engine protection. The results showed that Boots was able to extend its drain intervals from 75,000 to 100,000 kilometres, while also improving cold starts in chilly Canadian winters. Another customer was an even chillier challenge – Duron oils were used in the trucks and equipment of the Ekati diamond mine, 310 km northeast of Yellowknife. That test proved that the products could cut downtime through extended drain intervals, saving upward of $900,000 during the testing. How does racing come into this? Petro-Canada Lubricants has several sponsorships with race teams, including Arrow Smith-Peterson Racing in the IndyCar series and, more to the point, Truck Sport Lutz Bernau, which races in the FIA European Truck Racing Championship. As part of that partnership, Duron products are used throughout the truck – and Petro-Canada Lubricants is able to then analyze and track the condition of that oil. A 1,200hp truck that does 100 mph around a road course is certainly a good test bed for an engine oil, isn’t it? So, next time you’re filling your excavator with heavy-duty oil, keep this in mind: that oil has been put through its paces in a lot of different ways to be sure it will work well for you. (Just don’t try that 100 mph thing, okay?)

DOZER PUSHES PRODUCTIVITY TO THE NEXT LEVEL The new John Deere 850L dozer boasts several customer-inspired updates including a larger displacement engine, increased operating weight, new operator station and several improvements to maximize reliability and durability. The 850L incorporates an EPA Tier 4 Final John Deere PSS 9.0L diesel engine that provides a 10 percent increase in horsepower. At 225 horsepower (168 kW), John Deere says that the 850L has more horsepower than any dozer in its size class. Equipped with the popular Eco mode feature, fuel consumption is reduced by up to 20 percent, without sacrificing performance. Auto-idle and idle shutdown are also standard and further minimize fuel costs. Like all John Deere dozers, the 850L features a dual-path
hydrostatic transmission, now with 13 percent larger pumps than the K-Series. The new dozer is available with the widest Power Angle Tilt (PAT) blade in its class, according to the company. At 172 inches (4,369 mm), the new blade increases productivity, especially in grading applications. All 850L configurations now utilize an eight-roller design with 130 inches (3,302 mm) of track on ground, increasing productivity, stability and gradeability. It also comes standard with grade control-ready electrohydraulic (EH) valves – making it easy to add a grade control system. Owners also have the ability to purchase the machine with John Deere SmartGrade. This technology is integrated into the dozer – eliminating external cables to the masts, which
reduces breakage; the removal of the masts from the blades helps decrease vulnerability to theft and damage. SmartGrade technology removes the need to install blade-mounted sensors and components daily, reducing setup time, and allows operators to get more work done.
ASV
HIGH OUTPUT POSI-TRACK LOADER PROVIDES MAXIMUM PERFORMANCE
The new mid-frame, vertical lift VT-70 High Output PosiTrack loader features high torque and an efficient hydraulic system for maximum performance with even the most heavy and demanding attachments. It offers 207 foot-pounds of torque. High torque allows for maximum performance, high speeds and minimal engine bog down in all applications. ASV built the machine with a turbocharged 74.3-hp Deutz 2.2-litre diesel engine. Drive motors transfer the torque to ASV’s patented internal-drive sprockets. Internal rollers reduce friction loss in the undercarriage, resulting in maximum power being transferred to the track
regardless of drive speed. The engine meets EPA Tier 4 Final emission standards utilizing a DOC-only exhaust aftertreatment without a DPF or SCR. The direct-drive pumps optimize performance over belt-driven pump systems, allowing the machine to run attachments more efficiently than even higher-horsepower competitive units, according to ASV. The CTL’s hydraulic system includes 3,300 psi of auxiliary pressure and a 22.2gpm standard flow. An optional 27.4-gpm high-flow system is available for even greater performance with demanding attachments. Built for peak efficiency, the system features large line sizes, hydraulic coolers and direct-drive pumps, transferring more flow and pressure directly to the attachment. The VT-70 High Output has a rated operating capacity of 2,328 pounds and a tipping load of 6,650 pounds. It is 65.6 inches wide and has a 126.5-inch lift height. The machine features speeds as fast as 11 mph. A self-levelling system allows attachments to stay at a set position while lifting. Operators can use the unit with all standard attachments. ASV customers will see maximum benefits of the VT-70 High Output’s power and performance thanks to the machine’s patented purpose-built Posi-Track undercarriage which allows customers to use this CTL as an all-terrain, all-season machine with maximum control, flotation, traction and pushing power in steep, wet, muddy and slippery conditions.

IN-DEPTH REPORT: DOZERS
PUSHING PRECISION By Lee Toop, Associate Editor
I
t used to be that contractors would use crawler dozers for a very specific type of job: pushing a whole lot of dirt in a short amount of time. They are a workhorse for cutting down to grade, even today, but with advancements in technology owners are using these powerful machines for much finer detail work than ever before. We asked our industry experts to tell us how the dozer landscape is changing and how pushing dirt has turned into much more.
Changing jobs
Nearly a century ago, some bright engineers had the idea to put a pushing blade on the front of an early crawler tractor, and the dozer was born. Since then, it has been used around the world for bulk material movement – cutting massive amounts of dirt and moving it around the jobsite. Today’s dozers, though, are taking advantage of new developments that bring far more to the table than just that. “Customers used to use the dozer just for the big, heavy pushing and maybe some land clearing, but then they would bring in other machines to do finish grading and other tasks. Now, it seems like the dozer is doing a lot more of those applications – heavy dozing, spreading, finish grading, clearing, all of that,” said Sam Meeker, Caterpillar product application specialist for dozers. “Some of the developments that we’ve done have been related to making the machine more productive in those applications.” For Cat, the D6 and D6XE dozers are an example of how new applications are considered in the new designs. Meeker explained that the company’s experts saw that customers needed machines that run more smoothly for faster finish grading, and took a new look at how to make their dozers more effective in that operation. “We found more and more customers using their dozers for that application and they weren’t satisfied with the results they were getting. So, we started to look into
12

>> JULY/AUGUST 2019
it and took our typical 8-bottom-roller undercarriage for LGP (low ground pressure) dozers and started to work with it,” Meeker said. “We started working with the idler height, spaced the rollers a little differently, and found that sticking another roller in there made it a little smoother. So, we stuck another one in for a total of 10. That lets the customer go a little faster and be a little more productive while they’re doing high-speed finish grading or spreading applications.” Along with more precision in their design, dozers are being used more frequently with modern grade control systems. With experienced operators retiring and newer users climbing into the seat, having technology to help hit the right grade at the right time is important, according to our experts. “Komatsu is helping by providing grade control technology that is proactive, so that the operator can run the machine like an experienced operator,” related Jonathan Tolomeo, product marketing manager with Komatsu America. For Komatsu, that means the new proactive dozing control introduced earlier in 2019, which adds aspects of machine learning to its automatic systems, allowing operators to hit their grades much more easily. “The new proactive dozing control took the industry’s typical reactive grade control and improved it by turning it into the industry’s first proactive grade control; the new system continuously collects terrain data, giving the system an understanding of the terrain around the machine and allowing it to increase production beyond finish grade,” Tolomeo said. A deliberate approach to machine control has been incorporated into the Case Construction Equipment dozer line, according to Nathaniel Waldschmidt, product marketing manager. “These machines need a quick learning curve, and a big part of that is machine control. With this technology, contractors are able to see notable gains in productivity, reduced wear and tear on equipment, and significant reduction in labour,” he said.
JOHN DEERE 850L
IN-DEPTH REPORT: DOZERS
CASE 1650M XLT Case has introduced the Universal Machine Control concept, giving contractors more flexibility when purchasing a dozer, Waldschmidt said. “Universal Machine Control allows contractors to buy the machine from the factory with a universal blade guidance system harness, universal machine brackets and mounts, and universal jumpers to integrate into any of the major machine control systems on the market. Any contractor can now take a Case dozer with universal machine control and integrate it directly into any fleet-wide machine control deployment.” Mastless systems like John Deere’s SmartGrade are becoming popular for machine control; according to Nathan Horstman, product marketing manager, crawler dozers, Deere’s SmartGrade cuts down on the number of finish passes and helps reduce undercarriage wear while improving productivity. Elsewhere, customers are looking for other features as well, including the company’s Power-Angle-Tilt six-way blades. “The 950K PAT dozer, which offers the only six-way blade in its class, can complete both large

dirt moving jobs and finish work, eliminating the need to haul in a finishing dozer,” Horstman said. “This combination has been a real game changer for our customers.”
Smooth driving, smooth surfaces
All of the power that dozers generate for pushing dirt has to come from someplace, and numerous updates have taken place surrounding the driveline. Deere’s customers have been looking for a machine to give them the upper hand, a demand that has resulted in development of the 850L, Horstman noted. “We upsized the hydrostatic transmission so that the new 850L could push more material in less time. The larger hydrostatic transmission in the 850L also allows the engine to run at a lower speed, optimizing fuel economy and improving durability.” Long life and reliability are important to Komatsu customers, and Tolomeo said the company has kept that in mind through its design and development of new machines. “Our driveline components are designed for long life and reliability. . . our components have tight tolerances and are extremely reliable,” he advised. “Anyone can tell you that you need to keep your oil clean and operating temperatures to a minimum; our dozers are enhanced with an excellent filtration and cooling system to increase component life.” In designing the new D6 machines, Caterpillar has brought several innovations to the table that can help customers be more efficient, Meeker noted: the four-speed lockup clutch transmission on the D6 and electric drive on the D6E. “What we’ve done is inserted a gear between first and second – I call it 1.5. When an operator is spreading trucks or 20-ton tandems of material on the jobsite, what he wants to do is hit that pile in second gear. . . then he’ll obviously slow down and downshift as he goes through the pile, then upshift on the back of the pile as well. Well, with that gear 1.5, when he hits the pile in second it downshifts to 1.5 instead of 1, which helps to keep his speed up and keeps the momentum and productivity of that tractor up,” Meeker explained. Combined with a lockup clutch, that ensures the machine is working as efficiently as possible. On the D6XE, Cat’s electric drive provides pushing power and productivity similar to a powershift transmission, while adding efficiency through reducing the amount of heat it generates. Using a
“switched reluctance” system the generator only produces the necessary amount of power for the job it’s doing, Meeker noted. “You can vary the amount of energy you want the generator to make – if I’m doing light duty work, I’m only asking the generator to make a little energy, therefore it only asks the engine to make a little bit of torque. When I want more power I ask the generator to make a little more, and therefore it puts more load on the engine,” Meeker said. “So, we can really finely control the amount of power we’re asking for, and the amount of fuel the engine consumes.” Fuel efficiency has also been built into the newest Case machines; Waldschmidt notes that the M Series dozers were the first in the industry to be powered by an SCR Tier 4 solution. “This type of aftertreatment system lets the engine run at peak performance with no regeneration and no related downtime. The M Series also features a hydrostatic transmission that is able to deliver best-in-class drawbar pull while achieving up to 10 percent greater fuel economy over the previous generation of machines.”
Technology takes the lead
Grade control is just one way in which technology is being used to improve dozer operation. According to Caterpillar’s Meeker, additions that help in the ongoing transition from older, more experienced operators to a new group in the workforce are important. For Cat, that has meant some additions beyond Cat’s own 3D GRADE technology that make the job easier for newer operators. It starts with slope indication, which gives the person in the seat the precise percent of slope the tractor is working on, and then adds the company’s Stable Blade – an inertial measurement unit that detects when the machine is moving up and down to stabilize and smooth out the motion of the blade. From there, Cat also offers Slope Assist, an advanced version of the slope indication system. “It takes the same reading that we provide the operator but controls the blade to those slopes. So, if the plans or specs to say to put in a zero percent grade in for a house pad, the operator can use Slope Assist to lock that blade in,” he said. “If they need a 16 percent slope for a pond, let’s say. . . they can use Slope Assist to dial that in, click the automatic button, and it locks that blade in at that 16 percent slope. It’s very inexpensive, it works great, it’s an exclusive in the

industry and it’s a great little tool to help operators be more efficient.” Integration of grade control through the dozer’s systems is growing and means operators can do more jobs across the site, said Deere’s Horstman. “Grade control technology enables dozers to be fully utilized throughout the site development cycle, from clearing all the way to the final pass for paving,” he said. “Another big advantage of grade control is that it eliminates all the guesswork – the operator knows the exact cut or fill required, so they only move the material once, putting it in the right spot the first time.” Liebherr also offers operator assistance at several levels on its new generation 8 crawler tractors, including the PR 736 G8 introduced at bauma. The assistance system starts with “Free Grade,” for active blade stabilization during fine grading, “Definition Grade” for automatic blade positioning when creating 2D grades, and “3D Grade” as an optional GPS machine control system to model complex terrain shapes, using the standard roof-mounted GPS/GNSS antennae. Liebherr also offers its Active Sensor Control, which stabilizes all blade axes, while two independent, permanently mounted integrated sensor circuits (gyroscopic and inertia sensors) allow for higher grading speeds and perfect fine grading.
creased durability,” he noted. Case’s M Series dozers offer operators a number of adjustments and other features, noted Waldschmidt. “Operators can adjust sensitivity of the blade movement to match operator preference and jobsite requirements. These adjustments to blade sensitivity are made through the Advanced Instrument Cluster,” he said. “There are also dedicated buttons for automatic Blade Shake to help with shedding material off the blade, and a Fine Grading command, which instantly cuts blade speed by 40 percent for increased accuracy.” Meanwhile, John Deere’s 850L has gone for the “bigger is better” concept, Horstman noted. “John Deere is offering an all-new 172-inch blade, which is the widest PAT blade offered in this size class. This means our customers can move more material in every pass, to get the job done faster,” he said. “Across the entire Deere dozer lineup, our blades come standard with mounting provisions for the major manufacturers of grade control systems.” An advanced six-point blade cranks up the production output from Liebherr machines, offering increased capacity and improving production output. An optimized linkage geometry helps facilitate grading as well.
Cutting edge blade design
Operator retention key
Of course, with all of this power, it’s important to have a tool that can hit the ground hard – the blade. Blade design has also seen a number of changes over time. Tolomeo said that Komatsu’s blades take their cues from the greater use of grade control and ensure they can work with the company’s proactive dozing control system, among others. “We can do even more with wider dozer blades in the fine grading applications. Komatsu dozer blades are built to survive, with large casting to disperse cyclic loads, guards to protect cylinder rods and a properly heat-treated blade to provide robust in-

With operators spending eight to 12 hours a day in the cab of their dozer, taking their comfort in consideration is important for manufacturers, Horstman noted. “We want to keep them as comfortable and productive as possible. With the 850L, we added features like a leather-accented high-back seat with heating and ventilation and automatic temperature control so that the operator can set the cabin temperature and then forget it for the rest of the day,” he said. “Another key focus area in the design of John Deere’s dozers is ease of operation and the hydrostatic transmission is a great example. When a John Deere dozer
“THE COMBINATION OF A SIX-WAY BLADE, GRADE CONTROL AND HYDROSTATIC TRANSMISSION INCREASES THE VERSATILITY OF ANY DOZER.” Nathan Horstman, product marketing manager, crawler dozers, John Deere encounters a heavy blade load, the power management system simply adjusts hydrostatic transmission to maintain ideal engine RPM, allowing the operator to concentrate on the work at hand, not shifting.” Case’s dozers use electro-hydraulic joysticks, which give better feel and responsiveness, and also offer a wide range of control customizations that are designed to make it easier for users to get up to speed on their machine, Waldschmidt said. “These allow the operator to better tailor machine performance to

jobsite conditions, including the ability to set blade sensitivity, steering sensitivity and shuttle sensitivity to smooth, moderate or aggressive. This allows the operator to adjust machine responsiveness and controls to their preferences and ground conditions.” In addition, machine/blade control technologies are continuing to add automation that handles jobs that operators would have had to do themselves in the past, Waldschmidt added. “One option we offer is the Case SiteControl CoPilot, a simple 1D solution comprised of an IMU, wiring harness and in-cab display. The affordable and easy-to-use system allows operators to set a desired slope/grade reference, and the system automatically holds that slope and grade without the need for lasers, masts or GPS.” With a cab fully separated from the machine combined with a noise-optimized drivetrain, reduced vibrations and noise are a benefit for Liebherr dozer operators. Features like a grab handle with an integrated joystick for the rear ripper help give more stable seating in uneven terrain, and access and descent lighting with a delay function make for additional operator safety. Liebherr also offers a 9-inch display in its new information and control station.

When it comes time to pick a dozer for their operation, Tolomeo encourages buyers to keep three things in mind: reliability, durability and uptime. “Customers have enough to worry about, and we don’t want them to have to worry about their dozer’s uptime. Komatsu provides reliable, robust dozers with the industry’s best undercarriage. The undercarriage is the highest owning and operating cost for any dozer, so to reduce costs for our customers, Komatsu PLUS (Parallel Link Undercarriage System) is offered on all dozers,” he related. Horstman encourages contractors to consider versatility when they are looking for a dozer. “The combination of a six-way blade, grade control and hydrostatic transmission increases the versatility of any dozer. This combination supports high productivity in all applications, from rough grading to finishing,” he said. “Six-way blades offer increased blade maneuverability and can be used in a wide range of applications. Grade control supports the experienced operator with the ability to hold consistent grade throughout the day and enables a novice operator to get up to speed quickly. The hydrostatic transmission gives the operator ultimate control over the dozer with the ability to fine-tune ground speed for any application.” Overall, it’s important to keep the overall cost of ownership of any machine in mind when making a big decision for a business. “Pay attention to things like fuel efficiency, dealer support and technology compatibility,” advised Waldschmidt. “Business owners need to make sure that a machine is going to work with the telematics and machine control technologies that they currently have deployed throughout their existing fleet.” HEG

CUTTING-EDGE POWER AND EFFICIENCY Durable new Generation 10 excavator withstands the toughest jobsites
T
he SK850LC-10 is the largest Kobelco Generation 10 excavator. The manufacturer says this machine features cutting-edge power and efficiency capabilities to make downtime a thing of the past. The SK850LC-10 is more durable than ever and able to withstand the rigours of the toughest jobsites. This Kobelco excavator delivers a dynamic bucket digging force of 90,598 pounds to achieve leading-class work volume. Premier working ranges and a powerful 146,800-pound drawbar pull force enable the SK850LC-10 to conquer rough terrain and slopes with increased productivity. This robust, 185,700-pound unit is powered by a 510-hp Tier 4 Final HINO engine, allowing it to tackle heavy-duty applications while remaining highly fuel efficient.
Impressive improvement in fuel economy
While operating in ECO-mode, the SK850LC-10 boasts an impressive improvement in fuel economy – approximately 17 percent compared to its predecessor. This boost in efficiency is a result of an enhanced hydraulic line layout that further reduces energy loss to ensure outstanding performance. A variable-geometry turbocharger also helps to lower fuel consumption, and a new selective catalytic reduction system decreases NOx emissions by 80 percent to provide low operation emissions. Operators can look forward to staying safe and comfortable in the SK850LC-10, regardless of the work at hand. An improved lever control force of 25 percent further lessens operator fatigue during long hours of operation, while added climate control outlets and an expanded cab interior provide a pleasant
work environment. A FOPS top guard, rear-view camera and swing flashers come standard on the SK850LC-10 to enhance jobsite safety. Maintenance on the SK850LC-10 is simple and cost effective. Easy access to maintenance data from the operation management system greatly improves ease of maintenance scheduling and ensures a long service life, while easy access to the cooling unit, engine compartment and electrical components ensure convenient day-to-day maintenance.
PROJECT MINOTAUR
A
mythical machine arose at CONEXPO 2017 with Case’s introduction of Project Minotaur. According to Case, Project Minotaur is the world’s first dozer–compact track loader hybrid. Since that unveiling the company has documented the journey of Project Minotaur in a series of videos. The machine features steel tracks and a new ripper design intended for severe ground conditions. Project Minotaur is currently in its second iteration. The CONEXPO prototype featured a radial lift pattern, but Case received feedback that a vertical lift pattern would be more desirable for this machine and made the change for the second version. Case says that the lift arm configuration wouldn’t make too much difference in dozing applications, but would add versatility to the machine for lifting materials into higher dump trucks. Another challenge in developing Project Minotaur is in ensuring that the stress of heavy dozing would transfer to the chassis, rather than just the loader arms, but the attachment still has to be quick and easy to switch out. A C-Frame designed to make switchout between dozer and CTL functions easy is patent-pending. There’s a lot of potential for this unique concept. “One guy saw it as a machine that could be lowered down a hole to help build a subway station,” said Brady Lewis, the project’s program manager. “Customers clearly got what it was, and we heard use cases we’d never thought of before.” Case has been doing field testing of Project Minotaur in Wichita, Kansas, and is providing updates of Project Minotaur at minotaur.casece.com.

T
oday’s heavy equipment is benefiting from innovation more than ever before. With research and development in engine technology, electronics, design and other areas booming among manufacturers, the machinery that rolls onto jobsites is constantly improving. For Hyundai Construction Equipment, that innovation has been a focus for some time, and its excavators and wheel loaders have benefited
>> JULY/AUGUST 2019
from a number of improvements – a goal that the company emphasizes will continue as it improves its own technological updates. “Hyundai has been a leading innovator in the development and application of various technologies for excavators and wheel loaders, and we will continue to provide technological leadership and innovation,” said Hyundai district service manager Stephen Adamczyk. Much of the technology going into
machines currently has to do with collecting and moving data, almost as much as moving dirt, and that data handling and management has been one target area for Hyundai’s development, Adamczyk noted. “On the ‘moving data’ side of the innovation equation, Hyundai has a well-developed head start in providing the information technologies that customers demand,” he said. “Now we’re focusing on ways to integrate and expand those technologies to
give customers timely operational information and the tools they need to analyze and apply that information to their fleet management, maintenance, acquisition and disposition decision-making processes.”
Remote-management systems a focus
Adamczyk pointed to the company’s remote-management systems as one area in which Hyundai has focused on in expanding its technology offerings. That focus has resulted in the HiMATE system, a GPS-based offering that works either through satellite or mobile network connections to monitor key machine components like the engine, hydraulics and electrical system. Adamczyk saves customers time and money by offering the opportunity for more effective preventive maintenance that can cut the time a machine is parked. “HiMATE allows users to view and manage operating information, select and activate alarms, and call up reports such as alarm incidents and maintenance status of a specific machine or combination of machines,” he explained. “HiMATE also supports theft prevention, through such capabilities as geofencing and alarm notifications.” HiMATE remains in constant development and improvement, and has become a basis for Hyundai’s ability to integrate other technologies into its machines. One example, standard in the HL900 series wheel loaders, is an onboard weighing system, Adamczyk noted; the system “accurately measures and logs payloads, whether loose material in buckets of other materials or other materials moved with forks or grapples, creating a wealth of operating information.” Hyundai is integrating the weighing system into HiMATE to make the data collected more valuable to the machine owner – it becomes immediately available for analysis and reporting. “We’re adding new capabilities to the weighing system itself, including easier to use graphical controls for the operator, and the ability to track up to three different materials or three different vehicles or receptacles into which the material is loaded,” Adamczyk said. Hyundai is working to integrate a diagnostics capability into the HiMATE system that will incorporate maintenance alerts and predictive parts and service diagnostics based on the machine’s operating data, he added. “The goal of integrating these technologies is to give Hyundai customers the information and data management tools to analyze their equipment’s performance, maintenance needs and machine life cycles. In construction equipment, data analytics is all about supporting the operation, understanding cost-of-ownership issues, maximizing machine performance, and achieving higher productivity and profits.” The ability to work with third-party software helps increase the benefits
of any type of technology, and Hyundai has taken that into account with HiMATE, Adamczyk said. “We make available the application-programming interface (API) for HiMATE to third-party developers of worksite management and related software products, fleet management companies with mixed fleets and others,” he related. “HiMATE complies with the industry standard AEMP 2.0, developed by the Association of Equipment Management Professionals.”
Improvements on the ground
While machine management is certainly important to success these days, performance on the ground is still key to equipment buyers and owners – and another area where innovation can be brought to bear. Hyundai has focused on a number of technology updates to help move dirt more effectively. “Recent enhancements in our HX series excavator product line include straight line travel, enabling the left floor pedal to be set via toggle switch for straight forward and reverse travel, eliminating the need for an extra pedal,” Adamczyk said. “Auto engine shutdown, standard with all key-type machines, can save fuel and operating cost in cases of long idle times, and available Fine Swing and Boom Float hydraulic system modes provide additional swinging precision and controllability when performing grading operations, respectively.” Hyundai also offers a full LED exterior lighting package, which illuminates the jobsite much more effectively when needed. All-Around View Monitoring (AAVM) is another new innovation the company has focused on, bring-
ing a tool that includes Intelligent Moving Object Detection (IMOD) to the HX excavators and HL900 wheel loaders. “This safety-enhancing system helps prevent jobsite accidents by maximizing operator awareness of the surrounding areas, providing a 360-degree field of vision,” Adamczyk described. It also includes a 3D bird’s-eye view and 2D, 4-channel view, and can alert the operator if a person or object is within five metres (16.5 feet) of the machine.
“We’re focusing on ways to integrate and expand those technologies to give customers timely operational information and the tools they need.”
Collaboration for machine control
Many operators these days swear by machine control systems on their machines as a great addition to efficiency and precision. Hyundai has collaborated with Trimble to bring machine control options to the table. “With the Trimble Earthworks system, calibrated and tested for Hyundai, the excavator works semi-automatically, enabling the operator to create smooth, flat or sloped surfaces much more easily, with greater accur-

acy and in less time,” he said. A number of Trimble excavators are ready for Earthworks installation, and a Trimble Ready option kit is available through Hyundai dealers, reducing the cost and complexity of installing machine control for the owner.

A LEARNING EXPERIENCE
Machine learning combines with 3D grade control to add precision and speed to excavation By Lee Toop, Associate Editor
A
utomation is the word of the day for machine control systems, with more options for greater precision regularly becoming available. Automatic systems that take advantage of advancing technology are making life easier for operators while also improving the bottom line for owners. One challenge that contractors face with machine control, however, is that
many systems are not modular – they are designed for a certain brand of machine and can’t move from one to the next if, say, an excavator is taken off a jobsite and another is sent to take its place. Topcon recently released an update to its automated system that brings a modular design to 3D machine control, while also taking advantage of new technology to increase the precision of grading operations. The X-53x automatic excavator system introduced this year at bauma
makes it easier for operators to reach the grade they need faster and with far less stress. An update to the company’s X-52x 2D system released two years ago, the X-53x system uses the MCX1 control platform that gives it more functionality in various areas.
Modular system for multiple uses
Kris Maas, director of machine control product management with Topcon, said the company has been working for several years to develop a modular system that could be used on multiple

platforms; the MC-X1 platform has been a key to reaching that goal. “The CPU power on that was extremely high two years ago, which means we don’t have to upgrade the system all the time – it’s future-proof. Secondly, we wanted to start working with self-learning and adapt to new technology that is coming out. People are working on autonomy and a lot of other new things. . . that was one of the requirements, to have self-learning capacity within the controller,” Maas said. “All of the pieces of the puzzle have fallen together, because we are using self-learning for the first time in a control system.” Maas said the X-53x is not only able to provide precise machine control, but it also adapts to the jobsite conditions from day to day. “If it’s in soft material one day and harder material the next day, and you’ve never done that before with that machine, the system will start learning that this is different, the valves need to react differently, and it will adapt to the situation,” he explained.
Self-learning aids in calibration
A large part of that self-learning comes in the calibration of the machine, Maas noted; where other systems may require the operator to enter in a number of values, test them, then readjust as needed, the X-53x works in conjunction with a total station to allow for wireless communication and calibration. “What you need to do is put the machine in certain positions, and the machine will operate by itself, going through the self-learning process. It will move the stick out and in, bucket out and in, boom up and down and learn how the machine reacts to the valve response,” he said. “There are pressure sensors; we know how the machine should react when it’s digging into soil. . . you repeat that step as many times as you want, and the system will keep learning all the time.” The X-53x system offers fingertip control to operators, who are no longer required to stare at their screen for indicators of grade to ensure they’re not over or under their target. “Previously, with an indicate system, if you’re doing a trench, you have to pull your bucket and stick in, your boom up. . . operation-wise, the only thing the customer will do now is bring the stick in, but the boom and bucket will be driven automatically,” Maas described. Operators will be able to stay on grade much more smoothly, reducing stress and improving operator comfort, Maas said. The X-53x will also increase speed as well. “They can go way faster because they don’t have to redo work anymore – they adjust for a custom grade once, and then they move on,” he said. “They can do a lot more work with an excavator than they did before, so it’s a big game changer.” For owners using a mixed fleet, the X-53x is cross-platform – it is available for certain machines from John Deere, Hitachi, Komatsu and Caterpillar at present, and will add more machines as testing continues, Maas noted. While the system has only been available commercially since June, it has proven itself in testing, and early adopters are finding it to be just what they are looking for. “It’s doing very well – one customer just bought 20 systems after testing one,” Maas said. For one contractor who has been working with the system, it has proven itself quickly on the jobsite. Using a John Deere 350 to dig out a house foundation, the customer told Maas that he could never have done the job manually without a second person in the excavation providing indications to get to the right grade. “He also said he couldn’t have done it as fast [without the X-53x]. . . we’re hearing that it’s faster, more accurate and [customers] couldn’t have done it without the system,” Maas said.

AGGREGATES & QUARRIES
IMPROVEMENTS INCREASE SAFETY ON AND AROUND JAW CRUSHERS By Lee Toop, Associate Editor
A
ggregate production, when you get right down to it, is a simple process: large rocks are bashed against large pieces of iron to make them smaller rocks repeatedly until they’re the size that a customer might want. That’s a bit of an oversimplification, but it captures the concept fairly well. It also illustrates why workers in quarries who are around the machines that do all that bashing are always keenly aware of safety. They want to know that when there are issues with how their crushers work, they can sort them out without putting themselves into an area of potential danger or damaging their machine. Primary crushers that handle the largest rocks on a jobsite are an especially challenging machine to manage when it comes to safety, but Telsmith has worked on adding features to its Hydra-Jaw crusher line that bring more safety to its large machines and the sites they work on. The Hydra-Jaw primary crushers have been on the market for some time, but the company introduced a number of new additions at bauma this past spring. These include updating the hydraulic system, modifying controls and several other changes. Josh Terry, a Telsmith product engineer, said some of the changes are designed to help get the machine back up and running when problems occur – without putting the operator in potential danger. “If you have a power interruption with a full chamber of rock, or you get a rock jammed, in the past you would have to clear out that crushing chamber before you could restart the crusher. You can’t start a jaw crusher with a full chamber or the belts are going to burn out, you’re going to overamp the motor,” Terry related. “Going way back, you heard stories about dynamite, or you would have 28

to get chains in there and get an excavator to try and lift individual chunks out. You’d have people walking around a crushing chamber full of rock trying to rig up rocks that are hard to rig because they’re stacked up.” In other cases, workers would use long bars, standing at the top of the crusher to try and move rock around inside the chamber, Terry said.
Hydraulic chamber clearing
Needless to say, those practices are less than ideal. Telsmith has added a unique hydraulic chamber clearing system that keeps workers away from the machine while getting the crusher back to work quickly. “Using the hydraulic clearing system, you can open and close the crusher, and break out all the rocks that are in the chamber,” Terry described. “It’s not going to be as fast as what the crusher would normally do processing rocks, but in 20 minutes or a half-hour you can have it completely empty and ready to run again – and that’s worstcase. The best case is that you just have something bridged across the crusher opening. . . a lot of times what you can do is just open up the crusher and get that rock started into the chamber, then go back to your usual settings.” Along with worker safety, the chamber clearing system protects the toggle, which can be damaged if the crusher winds up overloaded. “In a traditional jaw crusher, the toggle can either break or bend, or in a worst-case scenario it will lock up, stall and you need to find a way to release some of that tension,” Terry described. “Having a hydraulic cylinder in there means you can safely let that tension out.” Hydraulics also make it much easier to make pressure setting changes, Terry noted; rather than adding
or subtracting shims, a time-consuming process, the process is as easy as pushing a button. “Sometimes that means a crusher doesn’t get adjusted as often as it should, because it’s going to take some time out of someone’s shift to make that small change. So, they run it at a less than optimal setting,” Terry said. “With the hydraulic system, it’s a change you can do frequently.” To handle the additional work, the hydraulic system has been updated; what started as a gear pump system to make adjustments has been improved to meet those greater power needs. “The new unit is a piston pump system with a pressure compensated pump continuously running; it’s a 5,000 psi system to match the cylinder a little better,” Terry described. “What that means is that if you get a bunch of really hard rock jammed in the chamber and you need a little more force to clear it without stalling, there’s more capacity to do so.” The Hydra-Jaw crushers have received updates in other areas as well. Terry noted that the control systems have been updated, taking advantage of a new programmable logic control (PLC) unit that allows for monitoring of various conditions on the machine. A new touchscreen also helps make the crusher easier to operate, he added. “You don’t want to have to push a bunch of buttons and navigate a lot of different menus; the touchscreen menus are pretty intuitive,” Terry noted. With a lighter weight than other crushers, the Hydra-Jaw has drawn interest from quarry operators as a component in their wheeled portable plants, along with its more traditional stationary primary crushing role. “We do have some big primary stations we’re still selling. . . we focus on the bigger wheeled portable systems, though. People want to move it around the pit a little easier – that is an advantage,” Terry said. HEG

Rudolph serves as the vice president of operations for Cobalt Construction, the company chosen to work with the new owners of the historic railroad to expand and enhance service for the cruise ship industry. The railroad was originally built to transport those seeking their fortune during the Klondike Gold Rush in the late 1800s, and today still takes close to 7,000 passengers up 3,000 feet in elevation in just 20 miles each day. The breathtaking route is filled with glaciers, gorges, waterfalls, tunnels and trestles. White Pass Railroad changed hands over the summer of 2018, with new owners who have a unique understanding of the future requirements of the cruise industry, as well as a deep commitment to the historical significance of the railroad and Skagway itself. With the change came the opportunity to expand. They turned to Whitehorse, Yukon Territory–based Cobalt Construction, a large-scale earthworks company that specializes in road construction, bridges, mine development, 30

contract mining and mine site remediation throughout the north. “Our expertise has always been around anything that involves moving rock and dirt,” Rudolph said. “Building roads, dams, airports, contract mining, mine reclamation work – all of this served as groundwork for spinoff work with White Pass.” White Pass invested in a new turnaround loop to increase ridership capacity from 7,000 to 10,000 people daily, putting more trains in operation and providing a speedier return to Skagway. The existing system requires trains to decouple and creates a bottleneck. The new loop would fit as many as three trains, allowing them to turn around and head down the mountain.
Ballast rock needed for track stability
The project scope included clearing the site for the installation of track to create the turnaround, as well as crushing and screening ballast needed for track stability. The project came with unique challenges. Its remote location had the potential to hinder the supply of materials and manpower to get the job done before winter. Ironically, while Cobalt has built most of the major highways in Northern Canada, this site is inaccessible by road. “Everything that has to go into that jobsite – literally everything – goes in by train: The fuel, the explosives for blasting rock, the groceries, every-

thing. White Pass is supporting us 100 percent because we can’t do it without them,” Rudolph said. Cobalt management needed a crusher and screener to crush and size the thousands of tons of ballast needed, and the transportation constraints required the contractor to consider not only production requirements but also the load sizes of the equipment to ensure the railroad could transport it. Management sought advice from Bison Iron, a heavy equipment dealer based on the west coast. “We could have used a larger crusher, but we couldn’t have gotten it on the train,” Rudolph noted. “When we started to talk with Bison Iron, they understood the unique challenges, but also saw the great opportunity if the right equipment for the job could be brought in.” Conversations led Bison Iron to recommend two pieces of equipment manufactured by McCloskey. The Ontario, Canada-based manufacturer is known worldwide for its durable, high-production crushers and screeners. Ultimately, Bison Iron and Rudolph agreed that a J40V2 jaw crusher and an R70 screener would be the best fit for the job. Rudolph was sold on the sales support, the fit of the equipment for the project and the reputation of the manufacturer. After setting up camp, Cobalt got to work clearing a path for the tracks
through the solid rock mountaintop. The contractor primarily used a drill and blast method, moving about 26,000 to 27,000 cubic metres of granite by the time the project was complete. It wasn’t straightforward, however, as the work site was next to a lake which required environmental protection measures to be put in place and was constantly monitored for compliance. Crews installed floating silt curtains in the lake to catch blast debris. Cobalt was also responsible for supplying ballast to support the new tracks, which meant putting the new McCloskey J40V2 crusher and R70 screener to work.
Crusher handles rugged site smoothly
With its trim dimensions and track mobility, the J40V2 was moved onto the new quarry, set up and running in record time. The crusher quickly showed it could outperform much larger versions due to features like steeper angles on the jaw and wider opening for enhanced production. Cobalt used the equipment to crush granite to 2.5inch pieces for ballast. The material was then sent through the R70 screener to remove fines and create the finished product. The durable R70 was more than capable of taking on the job and paired well with the crusher. Both the crusher and screener were self-propelled, allowing maximum mobility around the site.
“Some of our guys have run crushers before and been around crushers. When we were considering purchasing the J40V2, my superintendent said these things are built tough. You see it out here – this is going to last a long time,” Rudolph said. Rudolph also emphasizes how important the after-sale support is, particularly in remote locations. He noted that Bison Iron spent several days on site assisting with setup to ensure optimal production, and was always available to answer questions over the phone. “Bison Iron was instrumental in our choosing McCloskey, and the support and training they provided was absolutely first rate. When you are in remote sites, having someone as knowledgeable and responsive as they are makes all the difference,” Rudolph said. Before the project shut down for the winter, the jaw crusher and screener ran 24 hours a day for 10 days to stockpile ballast for the startup in the spring. Crews finished with about 20,000 cubic yards of ballast. The site’s remote location brought additional challenges to the project. Emergency maintenance issues oc-
Cobalt’s McCloskey J40 V2 jaw crusher was used to break granite down to 2.5-inch pieces for ballast. casionally required a mechanic to be brought in by helicopter. In mid-November the casey car, which brought explosives to the site, couldn’t make it due to. The team called a work train up from Skagway, 20 miles away, to clear the snow. Partnerships are key to success, and Cobalt works hand-in-hand with the American work trains coming out of Skagway which work with the Canadian maintenance. The site sits right at the
border, and the cooperation is visually reinforced with the two national flags only a few feet from each other. In another instance of weather-related issues, a crew was stuck on site for four days in December because of whiteout conditions. Cobalt finished its portion of the loop project in December 2018. White Pass wrapped up installation of the ballast and tracks in early 2019 before the trains started on April 27.
Though the contractor is done with the White Pass loop project, Cobalt will return in spring to build more ballast for White Pass for maintenance and other projects. This will mean continued use of the crusher and screener – equipment Cobalt typically wouldn’t own – allowing them to prove their worth as White Pass has indicated it wants the contractor to work several more years assisting with upgrades to the entire railroad system.

REPAIRS ON THE ROAD
Truck size, technology and materials define service truck demands as mobile repair expands By Lee Toop, Associate Editor
D
owntime is a curse word among contractors, but the fact is that it’s hard to avoid it sometimes. When a machine or truck suffers a breakdown on the job, the need to haul that asset back to the shop just means that downtime is extended. Between mobile repairs and on-site service to help avoid breakdowns, mechanics need a reliable way to carry their gear and provide a portable shop setup to get the job done. That’s where service trucks come in, and manufacturers of these versatile vehicles have continued to develop their offerings to provide strength, reliability and the options mechanics need. While equipment dealers and large contracting companies are generally the core of the service truck market at present, there is a growing sector of independent mechanics who are offering on-site services, according to David Smith, fabrication/engineering manager with Oro Design, an Ontario-based manufacturer of service trucks. “There are equipment dealers who are doing these services, but there is also a subsection of independent mechanics – the field service industry is growing a lot, and a lot of people who have worked for Caterpillar or John Deere for 20 years are saying that if the dealers can charge a certain amount for field service then they can potentially go out and do it for less,” Smith said. “It might just be one guy with a service truck, but typically their rates are competitive and they quickly grow.” The big operators continue to be a big market for service vehicles, of course, and Tim Davison, product manager with Stellar Industries, said equipment deal32

ers are steadily increasing or replacing their fleets as mobile service continues to expand. “The core market still buying heavily is equipment dealers – the Caterpillar dealers, Komatsu dealers, people like that – and then construction companies, for the larger models. For the smaller crane sizes, the rental industry, whether it’s a larger operation or the smaller rental companies, are buying quite a few. And right now the oil and gas industry is doing fairly well – it’s not as dramatic as it has been in the past, but it is still a heavy segment for us.”
wind up paying additional maintenance costs because they are running over their designed capabilities, Smith added. “You’re kind of fighting a mental barrier where they don’t want to go to the larger truck, but there are also costs to go bigger. Our perspective is that it’s a better truck when you build it appropriately. . . you’re not building it right to the limit, and then if you need something bigger tomorrow then you need a new truck,” he said.
Range of truck sizes
Weight reduction is a target for Stellar beyond the chassis and its capacities, Davison noted; they offer aluminum bodies that can save 700 to 1,400 pounds over their steel bodies. “That particular series of body has gone up dramatically for us, to where it’s become a large portion of our business,” he said. “It’s a weight issue, but corrosion also plays a big part of that. . . you are going to have seams in a truck bed that may start to bleed a little rust here and there – with calcium chloride and mag chloride on the road that just exasperates the issue. With an aluminum body, we really do get almost a Tier One automotive finish on it, and that body is not going to show rust on it ever.” That’s important to Oro as well, which also builds mixed steel and aluminum bodies for its trucks. Smith emphasized that steel is still important in structural uses, and especially for the crane structure. “If you look at one of our trucks, almost everything is aluminum except the body – if it doesn’t need to be super strong to support 12,000-pound lifting loads, then we’ll try to make it out of aluminum.” When it comes to accessories, the crane is a big one when handling heavy equipment components and replacements. Cranes are a specialty for Stel-
Customers are looking for a range of sizes in their trucks; while Stellar is seeing continued demand for class 5 trucks carrying their bodies, Oro, which has been building trucks in southern Ontario for more than 25 years, has experienced a market shift going toward larger trucks. “Our market seems to be very heavy on the smaller end – the F-550 size truck, or the Ram 5500 with a 7,000 or 7,500 pound crane with 21 or 30 feet of reach,” Davison noted. Smith, though, said class 5 remains popular but there is a shift toward larger trucks to ensure owners can carry everything they need for any particular job. “They want to get everything in the truck, but there are limitations to what you can do with weight. . . the 550 has always been very popular, but I think there are many more options now – there is a lot more available in a weight class that gives you more payload to get around the issues with the smaller trucks,” Smith said. Mounting a crane on a smaller truck body cuts down payload significantly, and that has often led to users overloading their vehicles; if they avoid getting nailed for being overweight, those users often
Aluminum bodies cut rust
lar – in fact, Oro offers Stellar cranes on its service bodies – and the company has introduced a new crane, the EC3200 Aluminum, which provides up to 3,200 pounds of lifting capacity and a 15-foot reach while also reducing weight. Powering equipment and tools on service bodies is evolving, with more users interested in an auxiliary power unit (APU) as opposed to running equipment off their truck engine through a PTO, Smith noted. “Traditionally you would install a PTO on the truck to run the hydraulics, but with an APU you have a smaller secondary engine that will drive the hydraulics – it’s more efficient because it’s smaller,” Smith related. “The issue with running a pump PTO today is all the emissions systems they put on the truck make it so you can’t idle it anymore – if you idle it a lot you’ll have maintenance issues very quickly.” There’s a significant initial investment that goes into adding an APU to the design, but it adds capability to the truck that will pay itself off thanks to the fuel efficiency improvement – which Smith said can be 20 to 30 percent compared to idling. “More customers are seeing the value of that – customers are spending more on trucks these days. . . they’re putting more in the trucks and they’re building bigger, more expensive trucks,” he said.
productivity will continue to be the demand from service truck owners, Davison predicted, both in terms of the equipment used on the trucks and in how it is managed. Improving fuel efficiency is one area that Stellar is exploring, in terms of reducing fuel costs for owners, and another is looking at the maintenance aspect. “We’re doing a lot of things over the next year or two analyzing the performance of our equipment to make sure that we let the operators know when it’s time to maintain a piece of equipment, not when it’s time to repair it,” he said.

Technology making an impact
Technology is making an impact on service trucks as well; for Davison, one key area where this is apparent is in the crane control system. Stellar offers a remote control system on its larger cranes that can provide the operator with far more information about the load being lifted than ever before. “We show the actual weight of the load on the boom tip, and if they hover the load hook over the load, without even hooking it up, we can tell him what the capacity is,” Davison said. A screen on the remote can tell the operator the remaining capacity on the crane at that point, allowing the user to determine if the load can be lifted there or if the truck needs to be moved closer for more capacity. That cuts down on the amount of trial-and-error that may have happened previously, which can result in damage to the crane or truck. “As they get closer to overload, as well, we have a vibrator built into the handle – a lot of the time operators are looking at the load and paying attention to their surroundings, and may not always be looking at the radio remote handle,” Davison added. “If they’re getting close to an overload situation, the vibrator will shake the handle and let them know.” Owners are also using telematics more frequently, Smith noted, both for keeping track of their equipment’s location as well as to gather data and work toward greater efficiency.

VMAC
HVAC SYSTEM FOR MULTIFUNCTION CUTS TRUCK IDLING YEAR-ROUND The HVAC System for VMAC Multifunction announced at the 2019 Work Truck Show is designed to eliminate truck idling on the jobsite, reduce operating costs and provide operators with a climate-controlled vehicle year-round. “The HVAC System will be integrated with the VMAC Multifunction, making it the first and only engineered solution for medium-duty truck-cab heating and cooling, eliminating service truck idling on the jobsite year-round,” said Mike Pettigrew, VMAC’s marketing manager. “The new HVAC System will allow operators to seek relief from extreme weather conditions, all without idling their truck.” The system will offer operators a climate-controlled safe zone when they’re working in extreme weather conditions, whether it’s sub-zero, wet and windy, or sweltering hot. The HVAC System for VMAC Multifunction is being designed due to overwhelming requests from Caterpillar dealers across North America for a solution to eliminate truck idling on the jobsite in all weather. VMAC is working with Finning, the largest CAT dealer in the world, to develop the HVAC System to their specifications and requirements. By
eliminating the operator’s need to idle on the jobsite to heat or cool their truck, fuel usage will be reduced and hundreds of operating hours on each truck’s engine will be saved each year. Recent field tests show that up to $5,800 in fuel can be saved yearly, on top of savings in truck maintenance costs. Reducing engine hours allows for longer intervals between truck servicing, improving truck life and warranty. An added benefit is the opportunity to lower a fleet’s carbon footprint and environmental impact. With many municipalities enforcing strict anti-idling bylaws, fleet managers can ensure their fleets are following these regulations.

FIGHTING GRAVITY The challenges of placing concrete high up

orking with concrete has many challenges, such as getting the right temperature, getting the right mix, getting the concrete to the jobsite on time and getting the concrete from the machine to the site of placement. “All concrete contractors have to deal with the challenges of time, temperature, mix and access, but contractors that need to place concrete high up are subject to numerous other challenges,” says Stuart Galloway, president, Canadian Concrete Expo.
From the ground up
When working at ground level a ready-mix truck is all you need. “Mack trucks are ideal for con-

crete work, as they offer a number of features tailored to the concrete industry,” says Roy Horton, director of product strategy, Mack Trucks. “Mack’s lighter-weight 11-litre MP7 offers up to 425 horsepower and 1,560 lb.-ft. and is a popular choice in concrete mixer applications. The Mack Granite and TerraPro models are built on a chassis that is engineered specifically for demanding vocational applications.” The chute of a mixer truck starts about three metres up and gravity moves the concrete from the mixer exit to the placement area. That means that a few metres from the rear of the truck, the concrete reaches ground level. As a result, mixer trucks can’t place concrete far away or higher up than the truck. Contractors that need to increase the distance between the mixer exit

and the placement area – or who are working on a jobsite where the placement area is higher than the mixer truck – will sometimes use a conveyor belt to move the concrete from the chute of the mixer truck to the placement area. These conveyor belts are designed to attach to the truck and run power off its PTO. With a conveyor belt, contractors can increase the height of concrete placement from just above ground level to about two storeys. If contractors need to place concrete higher up than that, they need to use another method.
Concrete boom pumps
Concrete boom pumps are used to pour concrete at great distances from the machines. The machines are comprised of a large truck; a multi-section, unfolding boom; and a pump (or two). The length of the boom tells you the size of the machine. “KCP Pumps’ 37-metre-boom machine, for example, is a smaller unit with a smaller footprint. It is ideal for house foundations, where there is not a lot of space on the jobsite, but they’re also not reaching very far,” says Jason Almeida, manager, Almeida Concrete Pumping. “When you get into commercial buildings or high-rising, then you will need a 52- or 60-metre boom, so you can reach farther into the building.” The first major added challenge for placing concrete on high-rises is that the mix is heavier. “When building a single-family house, contractors place a concrete footing and a foundation on which a wooden structure will be built. Since wood doesn’t weigh that much, only a lighter mix is required,” says Galloway. “When building a 100-storey-tall building, the foundation has to support the entire weight of that building, so a much heavier concrete is needed.” “We see contractors use a mix with a psi [pounds per square inch] of about 3,500 for single-family housing and a mix with a psi of about 14,000 for
[large-scale projects],” says Almeida. “That 14,000-psi mix is a lot harder to push, bogs down the engine and makes the pump struggle. To move a heavier mix, you need a bigger pump, which requires more power.” Concrete’s psi is a measure of its compressive strength. In order to move heavier mixes, KCP Pumps’ larger pump units usually come equipped with two pumps instead of just one. They range from 1,000 psi to almost 1,400 psi. (Boom pumps’ psi refers to their pushing power.) The larger units are also built on a larger chassis. KCP Pumps’ larger units have a Mack MRU 613, which has a 425-hp engine. “A 52-metre [boom] has a bigger chassis and a bigger truck, more wheels, more suspension and more power on the hydraulics so you can move more concrete faster, as well as move heavier mixes,” says Almeida. The second major challenge of working with concrete on high rises is gravity. “Things that contractors can get away with on a ground-level project, they don’t get away with on a highrise,” says Almeida. “There is an incredible amount of back pressure. Every stroke forward, the concrete wants to fall backward. The higher you go, the more the concrete wants to fall, so the pump is constantly struggling to keep the flow of the concrete in a forward direction.” Also, on high-rise concrete placements, the issue of time has even greater consequences. “Once you are in the process of placing concrete on a high-rise project, there is no down time. There is no Plan B. There is no rescheduling. You can’t wait for decisions to be made. You have just the one plan and you have to keep going with it,” adds Almeida. Although designed primarily for reach, KCP Pumps’ largest machine – the KCP 70ZS5170HP – features a 70-metre boom and can place concrete up 21 storeys. For concrete that needs

INNOVATION. to be placed higher than that a crane should be considered.
Cranes
Weight is a big factor when craning concrete. “Although tower cranes are very efficient at what they do, they don’t have large capacities when it comes to tonnage,” says Galloway. “This weight restriction also means that you are constricted to working in a smaller radius, since the crane’s lifting power diminishes the farther out you go from the tower of the crane.” The weight of a bucket of concrete (also called a skip) is often the heaviest load to be craned so, sometimes, companies have to use a larger-sized crane on a project to lift the skip. This can mean using a tower crane instead of a city crane. Smaller cranes, such as city cranes, are self-erecting and only need an engineer’s report that certifies that the ground underneath and around the crane’s working area is solid and stable before it can be erected. To assemble a larger crane, a mobile crane is used to mount it in a concrete sub-structure. Craning up concrete also increases the time it takes to place the concrete since the labourers have to wait for the empty skip to descend potentially dozens of storeys and then return again. “Lowering the bucket to the mixers below and then hoisting it up again can take five minutes on a 20- to 30-storey building,” says Galloway. Also, contractors tend not to fill the skip all the way to avoid spillage, so they are not getting a full load on each lift. Craning concrete has additional safety challenges. Lifting a bucket of liquid or loose materials will move differently than lifting a solid block. The centre of gravity of a bucket containing concrete will shift. Operators need to slow down and be smoother on the controls when
craning concrete versus craning a pallet or a solid object. They also have to be more careful when choosing a lift path so that the concrete isn’t lifted over people. Labourers pouring concrete on the top floor are working under a suspended load. There is the potential to be pinned between the bucket and a wall or some other obtrusion or for the bucket to land on their boots. “From reach to fighting gravity to pumping power to the extra time needed to complete the work, there are many challenges to placing concrete high up,” says Galloway. “Once you know the circumstances of your pour, you can choose the equipment you need for safe and efficient high up concrete placement.” Article submitted by the Canadian Concrete Expo, January 22-23, 2020, Toronto, Canada.

he construction industry is sometimes described as being slow. Often this refers to how long it takes to complete a project, especially when multiple industry specialists are involved. However, more and more the construction industry has been referred to as slow to adopt new technology. This is especially true when testing the compressive strength of concrete. Currently, the most common practice is to use cylinder break tests. However, this process is not always accurate and reliable. Many factors, such as curing conditions, the size of the cylinders compared to the on-site slab, and improper handling and transportation of field-cured cylinders from a jobsite to a testing facility can skew the strength data which can result in a weak concrete element. Testing compressive strength with wireless maturity sensors can eliminate these problems.
What are wireless maturity sensors?
Using cylinder break tests to monitor the strength of concrete requires some patience. Not only does it take time to cast the cylinders and arrange for a lab to test their strength, it takes an additional three days before results are available. But, with wireless sensors, like Giatec’s SmartRock, updates are given in real-time on the early-age strength of the concrete based on the maturity method. Once secured on the formwork and embedded in the concrete, these sensors measure the temperature of the slab and correlate this data to the concrete’s strength based on the maturity equation, according to ASTM C1074. This data is easily and quickly updated in the SmartRock app on a mobile device so that contractors always know the temperature and strength of the in-situ element. Adopted by numerous DOTs and building codes, wireless maturity sensors have been used in over 4,000 projects worldwide. With these sensors, concrete temperature and strength is continuously logged, making the data more accurate than ever. Having this information available at all times allows for better tracking and control of the quality of the structure. If a problem occurs in the concrete’s curing, the team will be notified immediately. This allows
Updates are given in real-time on the earlyage strength of the concrete based on the maturity method for quick and well-informed decision-making. In cases of structural failure, this constant logging of information can reduce liability. Additionally, generating reports that are easy to understand and share also allows for this data to be sent to any stakeholders right from a mobile device through the Giatec360 cloud.
Making project management easier
When using cylinder specimens to monitor the strength of concrete, break tests are performed by the lab at specific ages, i.e. after three days, seven days and twenty-eight days of curing. Having to wait for this data to come back often results in unnecessary delays on a project. This can add risk to meeting contractually obligated deadlines as processes often need to be repeated or extended. With wireless maturity sensors, this critical information is available right away, whether it’s in twelve hours, two and a half days, or even five days, so that contractors know when concrete has reached 75 percent compressive strength. Workers can then act immediately and start tensioning or stripping forms. This can save days, even weeks, on a project. Fully optimizing the jobsite in this way also saves significant costs, both in materials and labour.
In the field
With concrete maturity sensors, field personnel don’t have to untangle, cut or fuss with wires. Going wireless means no longer having to rely on break tests for concrete strength data. This makes the testing process much easier and faster as specimens don’t have to be cast. Once these sensors are installed, they can be connected via a walk around the jobsite with a smartphone. Data is automatically collected and shared with all team members.

Proprietary FLEX Controls on the S-Series take the guesswork out of any project and increase the life of the concrete mixer. FLEX Controls improve concrete mix and efficiency with consistent loading, mixing and pouring. Additionally, programmable settings help reduce operating inconsistencies. Oshkosh engineering teams conducted multiple visibility studies that paid off in a thoughtful design that maximizes the view and enhances operator assurance. A larger cab allows for easy in and out, with improved ergonomics and more accessible electrical systems. In addition to improved ergonomics, expanded visibility and ease-of-use, four times more shock absorption means less vibration and a more comfortable ride for drivers. Easier steering means drivers can move where they want when they want, both on and off the jobsite. The front axle features field-proven Oshkosh Defense military components to provide maximum durability. This lighter truck allows for more concrete per load and decreases the number of trips. Downtime for service is decreased thanks to improvements that lengthen the life of components and protect against corrosion while making them easier to access during service.

DEMOLITION & RECYCLING
CLEAN AND COOL KEEPS C&D SITE RUNNING Sennebogen material handlers fit the bill for busy recycling facility
N
o surprise: running neckdeep inside a building that moves up to 800 tons of construction and demolition debris (C&D) every day is going to be tough on a machine. Just ask Sun Services, a C&D recycling facility on the U.S. east coast. Maximizing uptime was top-ofmind for Sun Recycling partners Brian Shipp and Andrew Springer when they recently purchased a new Sennebogen 818 M material handler from Midlantic
“Downtime for general maintenance and blowing out the machine because of overheating has become almost negligible. . . these 818s have been a great addition to our fleet.” Andrew Springer 40

Equipment. It was the third 818 they had purchased over a 14-month period. Their facility, first opened in 2013, started with a conventional fleet of wheel loaders and excavators. Looking for alternatives to load their new shredder, their wish list led them to consider replacing the excavator with material handlers. “We wanted an elevating cab,” Shipp recalls. “And we needed rotation in the grapple in order to pick out material that shouldn’t go into the shredder.” But a material handler that could live in the recyclers’ extreme environment remained a top priority.
every day, six days a week. They deploy dumpsters and roll-off trucks throughout the DC region. Loads of construction and demolition debris, asphalt, dirt, metals, drywall, wood, carpeting, furniture and other waste materials are all dropped on the facility’s tipping floor. Then, one of the 818s goes to work. The system runs flat out for 10
hours straight to process and sort the mixed waste into various recycling streams. Employing about 50 workers and drivers, the whole operation takes place under roof, in a fully enclosed building. Metals and concrete are sold into recycling markets. The residual stream goes to a nearby energy-fromwaste producer.
Serious about recycling
Shipp and his father Gary first got in to the trash business with Springer in 2004. As their knowledge of trash hauling grew, their interest in new processes for recycling grew. Following a 5-year process of licensing and planning, they built the new Sun Recycling facility with the goal of sending no material to a landfill. With the success they’ve achieved, Sun Recycling is now able to offer LEED credits to projects that use their services. “We are serious about recycling; we don’t just pay lip service to it,” said Springer. “We believe recycling will only become more important. There aren’t many companies recycling at our level.” Today, their facility receives 125 to 200 truckloads of waste material
>> JULY/AUGUST 2019
Sun Recycling selected Sennebogen 818 material handlers for the range of tasks required within its facility.
Cycle times are critical.
“We can’t be down,” says Shipp. “We only have 250 yards of metal storage in three bunkers; and another two bunkers for concrete. However, we don’t have the capacity to store our residual material stream. We have to truck material out immediately. We watch those numbers pretty closely day-to-day, to make sure we’re moving out at least as much as we’re bringing in.”
Simple search for the right machine
Finding the right machine to feed the shredder non-stop turned out to be a simple search. Shipp and Springer enjoy a solid relationship with Midlantic Equipment, their Sennebogen dealer, who have supplied all of Sun Recycling’s other mobile equipment. “We needed a machine, and our territory rep at Midlantic, Shane Pinzka, was able to demo an 818 quickly,” says Shipp. “One of the reasons we selected Midlantic was because the support was way better than what we were getting. I can call my salesman and a tech is here within an hour.” The first 818 proved it was up to the task. “We have a lot of dirt, a lot of dust, a lot of heat. . . it’s not good,” Springer admits. “Our machines look terrible at the end of a week-long shift. With the 818, we still need to pause to blow out the radiators periodically, depending on weather, but it does a much better job of not overheating, compared to an excavator.” All Sennebogen machines are equipped with powerful reversing fans to help them run cool in harsh conditions like this. For an extra boost, the Sun Services units were fitted with a custom pre-cleaner. A continuous stream of walking floor trailers is ready to transport the plant’s residual material to an energy plant. “Residual” covers about 40 percent of the material processed there.
The need to move product efficiently into the trailers led to Sun Services’ purchase of the second 818 M. “We made some changes to the building to improve our load out,” Shipp explains. “We had been using our wheel loaders, but we realized that another 818 would be the best fit for that end of the operation.” With the 818’s elevating cab, operators are able to see into the trailer as they place the materials, so they can fill holes and finish the load quickly. According
to Springer, the operators are also pleased with the new machines. “They love how big and comfortable the 818s are inside – especially the big guys!” The latest addition to Shipp and Springer’s Sennebogen fleet is identical to the first two machines. Again, the driving factor behind the purchase is uptime. “We cycle in the new machine while one of the other two are in for scheduled maintenance,” says Shipp. “And if our wheel loaders get a bit behind on the piles, our 818 is
ready to jump in.” The owners appreciate that consistent operation is essential to keep their process cost-effective for customers. Day-to-day, the 818s are keeping up with the demands of the pace and the working environment. According to Shipp, “Their downtime for general maintenance and blowing out the machine because of overheating has become almost negligible. We used to have to do that all the time. These 818s have been a great addition to our fleet.”

>> EQUIPMENT FOCUS: LIGHT COMPACTION
P
roperly done, soil compaction adds many years to the useful life of structures by increasing the foundation’s strength. To compact soil in confined areas, vibratory rammers and plates are typically used. Traditionally, these machines have been powered by gasoline and diesel engines; however, due to increasingly strict environmental regulations, rammer manufacturers have been required to engineer new solutions in order to comply to the Environmental Protection Agency’s standards. Wacker Neuson redesigned its own two-cycle rammer engine in order to exceed all EPA emissions regulations, but the company didn’t stop there
NO CORDS, NO FUMES COMPACTION EQUIPMENT
THE FUTURE OF
COMPACTION BY FRED PAUL, SALES ENGINEERING MANAGER, WACKER NEUSON

HEAVY EQUIPMENT GUIDE
>> JULY/AUGUST 2019
Today, continued emission regulations and operators’ health and safety concerns have pushed for new developments in confined area compaction equipment. Wacker Neuson has introduced the industry’s first cordless, battery-powered rammers and plates. The manufacturer’s line of zero-emission compaction equipment offers a new solution for contractors and rental customers to access commercial interior construction or indoor renovation projects, or use in poorly ventilated areas including trenches and tunnels. They can be used on projects with strict emission and noise guidelines such as hospitals, schools and residential areas, or any project where a non-spillable fuel source is required. The AS50e cordless, battery-powered rammer was the perfect solution for a plumbing company replacing sewer pipes on a school renovation project near Milwaukee, Wisconsin. Trenches were dug throughout the interior floor of the school’s athletic building and sewer pipes replaced. The job specified that vibratory compaction be used on the backfill of the trenches. Due to students and staff using the building, the contractor was informed that no gasoline powered equipment could be used during working hours. “Typically we would use a gasoline compactor on a job like this, but that wouldn’t work for this sensitive application,” said Ryan Fetterolf, lead operator and plumber for the job. “The cordless rammer worked just like a gas model, but emission free and performed really well for this job.” Using cutting-edge battery technology, the compactors offer a variety of advantages that are ideal for contractors and rental houses. The maintenance-free electric motor dramatically reduces service time, contributing to the low cost of ownership. The machines are extremely easy to operate. A simple, push button start is all that is needed to begin working and the charging indicator light on the battery keeps the operator informed as to the status of the charge. Wacker Neuson developed the battery-powered compaction equipment platform as a modular concept. The battery and charger can be used on both the rammers and plates which increases flexibility and economic efficiency. Under typical working conditions, one battery charge can last a standard working day. The charge on the lithium-ion battery will last under continuous run time for about 60 minutes for the plate compactor and 30 minutes for the rammer. At first glance, this may not seem like a long time, but typical use during the compaction process is to run the machine for just a few minutes at a time. The battery can be easily be removed without tools and placed into the charger during idle times to keep the necessary charge. A common option is to have two batteries on site, so a fully charged battery is always at the ready. The battery system also provides constant power output over the entire discharge phase, providing full compaction performance from the first to last minute of work. The battery system has been designed to retain 80 percent capacity even after 1,500 charge cycles and is able to withstand tough construction site conditions. To put that into perspective, a rammer with a single battery can compact up to 9,000 linear feet of trench in a day, while a plate compactor can compact over 18,000 square feet, about 40 yards of a football field, in a day. These numbers increase dramatically when a second battery is on hand and charging while the machine is in operation. As industry trends continue to move toward zero-emission, easy-to-operate and low-maintenance machines, rental centre operators and environmentally conscious contractors will find that cordless, battery-powered compaction equipment will become essential to their equipment fleets.

THE EVOLUTION OF HEAVY-DUTY ENGINE OILS
Industry is adopting new motor oil standards for longer drain intervals and more protection By Lee Toop, Associate Editor
A
s industries like construction and mining move toward adoption of new engine oil standards, oil manufacturers have been working to improve their product and take advantage of the properties that are inherent in their new offerings. With several new products on the market, Petro-Canada Lubricants has been working with customers both on and off the road to improve performance for longer intervals between oil drains as well as enhanced engine protection performance. The Duron line of products has moved entirely to the new API CK-4 and FA-4 standards, which were the largest change in the industry in some time, according to Barnaby Ngai, Petro-Canada Lubricants category manager, heavy-duty engine and driveline oils. “It’s proven very successful for us – we’ve moved our entire customer base over onto these new product lines, and they are seeing the benefits,” Ngai said. “We do still continue to support the transition of users within the industry with our education platforms and training programs. Not everyone has converted; folks are at different stages with their equipment and adoption rate.” FA-4 has a slower adoption rate, in part because it is designed for newer engines, but Ngai said those users who have adopted the new fluids have seen results including extended drain intervals and better fuel economy. “There are always concerns that you’ll get better fuel economy but have more wear, that there’s a sacrifice to be made; I can say categorically that is not the case,” Ngai said. “You’re getting equivalent protection in your engine, and you‘re seeing extended drain capabilities.” Recently released products in the Duron line include Duron Advance
5W30 FA-4 engine oil, Duradrive HD long-drain automatic transmission fluid, and Duron GEO LD 15W40 and 10W30 for natural gas engines. Ngai said users of Advance are seeing potential fuel efficiency improvements of up to two percent, while Duradrive HD is the first transmission fluid in North America approved for Voith’s maximum extended drain of 108,000 miles. GEO LD, while designed for natural gas engines, can be a one-size-fits-all option for mixed fleets, as it can also be used in gasoline and diesel engines. “Gone are the days when you had natural gas engines and had a specific oil for them, and then you had a specific oil for gasoline and for diesel, and you had to put in processes to avoid misapplications,” Ngai said. “You can use this product in every type of power unit.” Duron products have been trialled in some of the most rugged situations possible. One Petro-Canada Lubricants partner is Dominion Diamond Mines, which runs the Ekati mine in the Northwest Territories. Ekati is set in a climate where winters can reach -40 degrees C regularly, and it is only reachable by air and a winter ice road. The mine has a fleet of more than 100 vehicles, from haul trucks to loaders and dozers. “The challenge, when they came to us, was they wanted to find a lubrication partner that had a heavy-duty engine oil tough enough to withstand their operations in the Arctic while also being able to deliver cost savings and extended drains,” Ngai related. A two-year trial which featured Duron UHP 5W40 heavy-duty engine oil generated approximately $900,000 in cost savings across the Ekati fleet, generated from product consolidation, extended drain intervals and maximum uptime.

Tire inspection transformed with TOMS
Kal Tire’s new Tire Operations Management System is harnessing data for powerful insights By Kaitlyn Till, Managing Editor
A
mining truck is only as good as the tires it rides on, and inspecting and maintaining those tires is a big job with significant implications for both productivity and safety. With its new Tire Operations Management System (TOMS), Kal Tire is demonstrating that tire management can benefit from more effective fleet inspections and improved planning and communication of required tire work. With TOMS, the company is making the tire inspection and reporting process clearer and more efficient today, while common language data capture and centralized data management will lead to predictive tire maintenance, AI recognition of damage and more effective training
“Over time the system will increasingly change from one that is a collection tool, which probably is 70 percent [of TOMS] today, to one that actually is driving recommendations and standard procedures.” Mark Goode, director of Business Insights for Kal Tire 50

for inspectors in the future. Historically a significant challenge for tire inspections has been the lack of a consistent, clear method for capturing and communicating damage issues. Mark Goode, Director of Business Insights for Kal Tire, said that the software and paperbased data collection methods traditionally used have been effective at gathering information for use in historical tire performance reporting, but haven’t been as efficient at capturing or communicating tire work that needs to be planned. “Tire work that needed to happen immediately was handled pretty effectively by the tire technician simply calling Dispatch on the radio,” Goode said. “But tire work that needed to be planned and that could take place at the same time as the equipment was down for other work was often missed as it wasn’t captured effectively, nor communicated. This led to a lot of tire work being unplanned and incurring unnecessary downtime.”

“The concept came from the fundamental recognition that Kal Tire, as a tire service provider, works primarily for the maintenance team on site and, as such, that we needed to use a similar maintenance planning tool as our customers,” said Goode. “In short, we needed to think and be able to talk the same maintenance language.” TOMS is a work-order-based solution built on an enterprise asset management system (EAM). A core concept of the system is to plan work and report on the successful completion of inspection tasks and generated tire work. A powerful feature of TOMS is that all information flows into one database. While the basic process of doing an inspection as defined by Kal Tire’s Safe Work Procedure doesn’t
significantly change, using TOMS, inspections are planned for each piece of equipment at agreed upon intervals. The inspector uses a pre-determined task list based on variables that are agreed upon with the customer up front in a Maintenance Activities Plan (MAP). The MAP is regularly reviewed and evaluated to ensure that it continues to accurately reflect the operation’s needs. “We use the core functionality of the system to produce a planning report for our customers that can be automated or run for a determined forward-looking period. This planning report includes all the tire or wheel work required for the period ranked by priority and organized by truck. This work typically covers upcoming rotations, rim NDTs and all identified work found as part of the fleet inspections,” said Goode. Another vital feature of TOMS is its use of one common language. This means that inspection findings, actions and priorities, for example, all have unique codes removing any ambiguity from written notes. Consistency has long been a problem in gathering data from written inspection reports. With its central database, Kal Tire acts as a gatekeeper to ensure consistency in coding and data capture remains intact. “Consistency of data capture is important for reporting purposes and also data analysis, but inspectors can always add their own notes [to the report]. If I’m inspecting a truck today, and you had done it last week, I can see your codes, your findings and recommended actions and also any notes you might have left me as well as any photographs you might have taken.” The first phase of TOMS was paper-based, the inspector using a common booklet of codes that includes all inspection, removal and scrap descrip-
tions. Kal Tire is now rolling out a mobile version that captures data via a smartphone or tablet, which allows for real time or close to real time data capture as well as clear communication of updates to the inspectors. “One key change for us with the move to mobile is the ability to capture images and bring them into the system,” said Goode. “What that means, from a process point of view, is when the inspectors are doing the inspection, and they’re capturing their findings, their actions and their priority codes and photos of any damage, that information is reviewed by the manager of the site before it goes into the system. We are giving the manager far more information than he had before; he can now physically see the damage.” The manager’s ability to see this damage leads to more value added conversations with inspectors and the customer about when tire work needs to be planned.
Harnessing data for customer productivity
Goode said that customers want concrete recommendations of things that they can do differently to improve tire performance and productivity. “We can trend and benchmark operational damage findings over time, along with track how long it takes for work to be completed. We plan to analyze the inspection data collected in conjunction with removal and scrap tire data in order to improve our ability to determine and predict when tire work needs to happen,” he said. “Given that a fundamental goal of tire management is to help ensure that our customer’s mining fleet is as productive as possible, it’s critical more focus is put on understanding how often and for how long trucks are actually out of service due to tires. Our customers typically know this for their own operations of course. We see tremendous opportunity to help our customers reduce that downtime through better analytics and benchmarking across operations. Improved tire performance is a key driver for sure, but improved planning and management of tire work can be just as important. And in many ways, these depend ultimately on the quality of the tire inspections taken and the communication process from them. That, with TOMS, is what we are looking to address.” Kal Tire is already working on research projects to provide feedback for customers. For example, the company has just started a project with researchers in Canada to determine the impact that rotations have on overall tire life and when it’s the right time to rotate. Goode hopes that this research will determine whether there is a direct correlation between when a site rotates tires and the impact on tire life.
The future of TOMS
It’s still early days for TOMS, which is currently in use at approximately 60 mining sites in 12 countries. “We’re only now starting to analyze the data and see what we can learn from it,” said Goode. For example, as Kal Tire collects more photos of tire damage through the TOMS system, it will be able to train AI to recognize damage using the common codes in the database. Goode expects that in a few years the AI will be able to recognize tire damage accurately and be able to support inspectors in their jobs. Goode also anticipates that this ability will be a good training tool for new team members and that it will help drive more consistency and in turn provide better information for continued analysis. “Three years ago we were using at least half a dozen different tire management software systems across our operations. Each of those systems had independent databases and each of those databases had different ways that tires were called. To get access to those databases and to map them together and try to say ‘Can we benchmark tire performance here?’ We just couldn’t do that three years ago.” Pushing all of the data to one database is a game-changer. “Over time the system will increasingly change from one that is a collection tool, which probably is 70 percent [of TOMS] today, to one that actually is driving recommendations and standard procedures,” Goode said. Putting that intelligence to use is something that Goode said Kal Tire is hoping to see over the next five years. “That’s the ultimate value. We can make every single one of our people as intelligent as all of us together.” HEG
