SAFETY IN THE TRENCHES

Work in and around trenches is dangerous – the trench can cave in or collapse, workers can fall into the trench, equipment and workers can come in contact with buried service lines, and ground workers risk being hit by heavy machinery.

Protecting the trench and maintaining clear job site communication are vital to keeping everyone safe. But trenching and work around buried utilities is an application where the latest technology can deliver huge safety benefits for everyone on the job site, in addition to significant cost savings.

Following trench protection procedures, such as using a trench box, shoring, benching, or sloping all reduce the risk to workers – but eliminating the need for workers to go into the trench at all is better. A game-changing technology solution that can keep workers safe in trenching operations is grade control, which eliminates the need for workers to measure depth in the trench during excavation operations and prevents rework.

In addition to being incredibly dangerous, the damage caused by buried utility strikes is a multi-billion-dollar problem worldwide – and new technology can help eliminate gas leaks, electrical hazards, water damage, and more.

In this issue, we explore cutting edge technology from RodRadar. The company has designed a solution that integrates utility detection technology into buckets for excavators. The operator can scan the ground using the bucket while seated in the cab and can see buried infrastructure on a touchscreen –eliminating the need for complicated interpretation of scanning data. This real-time scanning solution can save time, lives, and money. The operator always knows where underground infrastructure is buried while completing the job.

At September’s Utility Expo, look for the latest advancements in safety technology for trenching operations and underground utility detection and construction. The Utility Expo is unique

in its focus on giving attendees a hands-on opportunity to get familiar with the latest equipment and technology.

Following required safety procedures and ensuring proper job site communication between all workers is essential in trench work – but here the latest technology is a real boon to safety. If you’re attending The Utility Expo, we hope you have a great show and get the opportunity to experience some of this technology firsthand. If not, check out upcoming issues, and visit heavyequipmentguide.ca, for Utility Expo news and product introductions.

Danfoss has released a new white paper that details the need to decarbonize construction machinery. The white paper says that the construction industry needs to pay immediate attention to the possibilities of reducing carbon emissions from heavy vehicles to reach global climate goals.

The whitepaper says that construction machines worldwide emit 400 megatonnes of CO2 emissions, the equivalent of the emissions from international aviation, with 50 percent of these emissions coming from excavators alone.

Domenico Traverso, president of the Editron and Incubation Division at Danfoss, says the key to reducing the footprint of these machines is to implement energy-efficient technologies that can immediately reduce the diesel use in excavators and at the same time address some of the challenges for electrification.

Cities account for 70 percent of global carbon emissions. These cities will be where battling climate change will be won or lost. While passenger cars and smaller construction machines can more easily be made battery-electric and charged with renewable energy, the reality is more complex for excavators and other heavy-duty vehicles.

Compared to smaller vehicles, excavators operate under much more demanding conditions and require longer working hours between charges. This requires extremely large batteries to match the productivity of their diesel counterparts, resulting in resource-intensive production and higher upfront costs. Often, it is simply neither technologically nor economically feasible for heavy machines.

Many excavator work sites also lack the necessary charging infrastructure to support electric excavators. Large sites such as quarries often require field battery-swapping at the beginning and end of each shift and subsequent charging at depots. Operational challenges and logistical hurdles arise due to the immense weight of the batteries.

By improving efficiency, the requirement for batteries can be

most cost-effective way. Otherwise, it will not happen at scale. And this is where efficiency becomes a key enabler.”

The Danfoss Impact whitepaper investigates the case of construction sites and the readily available technologies that are transforming the construction industry, making low-emission construction sites achievable.

Excavator systems operate on diesel at a mere 30 percent efficiency, with 70 percent of engine energy being wasted. Danfoss emphasizes the significant potential for energy reduction by introducing measures such as variable displacement pumps, digital displacement, variable speed pumps, and decentralized drives. These technologies, along with energy recovery systems, can enhance efficiency and reduce energy consumption.

Implementing energy efficiency measures enables excavators to accomplish more work with smaller engines and less fuel, reducing the battery capacity required for electrification by up to 24.8 percent. The evolving technology can deliver fuel savings of 15 to 30 percent in excavators over 15 tons while simultaneously increasing their work capacity.

Prioritizing energy efficiency and exploring electrification possibilities will contribute significantly to the decarbonization of heavy-duty vehicles.

Ilove getting the chance to walk the floor at the ARA Show and CONEXPO. Equip ment companies introduce their newest products and prototypes, and I have the chance to see what’s coming –like the 2-tonne battery-powered excavator JCB debuted in 2019 that we [Cooper Equipment Rentals] bought off the floor. Four years later, we’ve got a dozen of them. Our

PERSPECTIVE CONSTRUCTION EQUIPMENT INNOVATION IS HAPPENING AT AN UNPRECEDENTED RATE – AND RENTING CAN HELP YOU KEEP UP

BY ROD LENTINO

customers want access to the latest equipment to help them get the job done, and when we invest in low/zero-emissions equipment that they can rent, everyone wins.

Construction equipment innovation is happening at an unprecedented rate. It’s smarter, safer, and more efficient than ever which means new capabilities to improve productivity, efficiency and

sustainability on the job site. At CONEXPO 2023, it was everything from robotics and AI to hydrogen-powered and electric vehicles. Komatsu showed the prototype for its first fully electric, semi-automated, battery-powered compact wheel loader. So quiet you can hardly hear them and requiring minimal maintenance, these machines can address the need for safer, more efficient, and zero-emissions equipment in the rental market.

With over 3 million square feet of exhibits at CONEXPO, there was no shortage of cool tech and shiny new equipment. It’s great to look at, but at the end of the day we have to think about what all these advancements mean to our customers’ businesses. As a contractor, do you have the right equipment to outbid your competition? Do you have a rental provider who can help you access the latest equipment and technology when you need it? The good news is, with so many options out there it’s never been a better time to think about your current and future equipment needs – and rental can help get you there.

DIVERSIFYING FLEETS WITH ELECTRIC

When the first electric machines came onto the market a few years back, there was

a mixed reaction. For some customers it was exciting to finally start adding these machines to their fleet. Others weren’t so convinced. There were major concerns around battery power and the added stress of having to plan their days around charging needs.

Electric equipment is now not only meeting contractors’ needs, but exceeding them. Customers are asking for more. Just this year, we received our first two 1.2-tonne Bobcat E10e excavators, and now we’re waiting on our first 3-tonne excavator. What’s great about working with a rental partner is the opportunity to “test-drive” equipment in real-world conditions on the job site. For those who are hesitant or have concerns over the technology, there is a huge amount of value in this riskfree approach. For example, having enough battery charge is a common worry, but with a little planning electric equipment can maximize uptime at a fraction of the cost of diesel equipment. Much of the battery-powered equipment we’re seeing today provides enough power to work through a full 8-hour day on one charge.

Electric machines have proven themselves to be as efficient and capable as diesel-powered equipment with the added benefits of reduced emissions and

BATTERY CONCRETE BUGGIES ARE GREAT FOR INDOOR CONSTRUCTION AND RENOVATION.

costs. All these new models will better support those operating in small indoor spaces and environmentally sensitive worksites where diesel exhaust is restricted. At CONEXPO, Bobcat’s range of three battery-powered compact excavators was a big draw. They’re incredibly quiet, which means they can be operated at all hours of the day, even in dense urban areas where noise can limit work hours. With zero emissions, they can also meet strict requirements around underground construction.

We also saw an influx of battery-powered tools and smaller equipment like buggies, which meet the needs of those contractors who want alternative options for compact equipment with zero exhaust emissions. We were the first to bring Allen Engineering battery concrete buggies to Canada last year, plus we have more Toro battery concrete buggies on order for 2023. These new designs are great for those areas inaccessible by the concrete truck or for indoor construction and renovation applications.

CONTRACTORS WANT TO KNOW HOW THEIR RENTAL EQUIPMENT IS OPERATING

We’re starting to see some real progress in understanding how customers want to access information and, more importantly, how they see it affecting their business. Understanding how frequently a machine is being used or if it’s the right machine for the job is key to better equipment utilization and improved safety. It’s really top of mind for us when we’re looking at new equipment and technology. As equipment becomes smarter, we’ll continue to access more information. For example, we’re seeing more demand for aerial equipment work platforms equipped with load sensors that can tap into equipment. They can tell the

user exactly how the machine is operating, providing better data for more informed decision-making on the job site.

Telematics can help ensure unused equipment isn’t just sitting around on the job site. There are lots of scenarios where equipment isn’t being utilized to its maximum efficiency. Maybe your scissor lift is only going up 50 percent, so a smaller model makes more sense. Or your excavator is idling for an hour before it’s being used, so you need to look at operator behaviour. There are some barriers to this, of course. Not all rental equipment has the technology to report data. Working with a branch that is up to date on the latest equipment and technology is key to accessing these benefits.

THE FUTURE IS AUTONOMOUS (AND SAFER TOO)

They’re not here yet, but autonomous job sites are on their way. There are a few things holding the industry back from more widespread adoption, but the benefits are being more understood. Autonomous equipment will not only help to limit the risk of human error, but increase

efficiency. When we talk to customers, safety is always the number one concern – so it’s no surprise we're seeing this sort of technology trying to redefine safety on the job site. As more prototypes move into real-world applications, we will see operators completely removed from the cab. At CONEXPO, Bobcat debuted its autonomous RogueX concept machine to show what the job site of the future will look like – fully autonomous and cab-free, it allows operators to accomplish multiple tasks at a time. With so much time being wasted as operators move back and forth between equipment, remote operation will have a big cost benefit. And with all the talk of labour shortages, we will need a variety of skilled operators for really precise work, while autonomous equipment, like the RogueX, can begin to replace more of the basic, monotonous work.

STAYING ONE STEP AHEAD IS ABOUT UNDERSTANDING CURRENT AND FUTURE NEEDS

As a rental partner, we have to think beyond just providing equipment – cus-

tomers may be leaning more into rental because they don’t want to worry about costs, but it’s more than that. They want to be one step ahead of the competition, using their rental partners to build long-term strategic relationships as a way to access a network of information on all their equipment. They want access to the latest equipment and technology, while also keeping their workers safe.

In today’s competitive market, there is no room for error. No one has an abundance of resources anymore; contractors need a lean and efficient operation if they want to succeed. They are looking to outsource their fleet for better reliability, more information, and data insights from a rental partner that can help them make the best decisions for their business.

ROD LENTINO has over 15 years in the equipment rental industry and is currently the director of rental at Cooper Equipment Rentals, one of the fastest growing rental businesses in Canada.

INTRODUCTIONS & UPDATES

DEVELON Mini excavator

The four-tonne DX42-7 mini excavator has a 47-net-horsepower engine and a conventional tail swing configuration. DEVELON says that the DX42-7 delivers fast cycle times and has efficient torque-limiting piston pumps that respond to load demands. A larger counterweight improves balance and durability. An optional four-way swing blade enables ideal blade positioning and reduces frequency of machine repositioning. The mini excavator is equipped with a standard thumb-ready arm. Thumb mounts are integrated into the excavator’s arm, eliminating the need for any welding when adding a thumb attachment. With quick-coupler hydraulic piping installed at the end of the arm, the DX42-7 eliminates the need for additional accessories when installing a compatible quick coupler. This design significantly reduces the time needed to switch attachments. Operators can choose between two control patterns, ISO and BHL.

that can be added to a new or existing system. Adding a McLana han dewatering screen to the end of its screw washer can achieve moisture content as low as 7 percent, the company says. Screens used in the UltraDRY system have a high G force, creating a deeper bed depth, a drier product, and more product processed. Heavy-duty urethane holds up to the demands created by deeper bed depths and higher G forces. Drive motors are oriented to ensure that screens do not need a brake or variable frequency drive to stop side motion. Additionally, it can come equipped with a divided deck design so that two separate products can be made on the same screen. A slurry pump can be added on when pairing the UltraDRY with a screw washer to divert the screen’s underflow water back to the screw’s feedwell. A spray bar is optional.

Upgraded excavator with longer

Komatsu’s upgraded PC130LC-11 with a longer undercarriage design increases lifting capacity by up to 20 percent compared to the previous model. This durable, reliable, and productive 97.2hp small conventional tail swing excavator is easily transportable and offers a unique combination of lightweight power and agility in a small package. Komatsu says that the PC130LC-11 uses up to 12 percent less fuel compared to the previous model (PC130-8). Fuel consumption on this excavator can also be reduced with the auto idle shutdown feature that can be set to automatically stop the engine after a preset amount of idle time. The Komatsu diesel oxidation catalyst helps reduce particulate matter by using passive regeneration over 98 percent of the time. For long-term durability, steel castings in the boom foot, boom nose, and arm tip help spread working loads away from high-stress areas.

Redesigned telehandlers

JLG is redesigning its SkyTrak telehandler line, starting with the all-new 6034 and 6042 models. Featuring a redesigned build, reworked functionality, reimagined technology, and refocused serviceability, these 6,000-pound-maximum-lift-capacity telehandlers are ideal for pick-and-place applications. These models have a lower operating weight than their predecessors – 14,500 pounds on the 6034 and 19,100 pounds on the 6042 – allowing for more efficient transport. Three 6034 models or two 6042 models can be hauled on a single flatbed trailer. The 6034 model is light enough that it can be transported with a standard pickup truck and trailer. The 6034 offers a lift height of 34 feet and forward reach of 23 feet. The 6042 provides a 42-foot lift height and 29foot forward reach. Both the 6034 and 6042 offer three steering modes: 2-wheel, 4-wheel, and 4-wheel crab. Both machines are equipped with a 74-hp, 2.9L Deutz diesel engine, and they have inching capability.

DIVE INTO DOZERS

THE LATEST TECHNOLOGY, INTRODUCTIONS & UPDATES

LIEBHERR OPERATOR ASSISTANCE SYSTEMS

MAXIMIZE GENERATION 8 DOZER PERFORMANCE THROUGH EFFICIENT BLADE CONTROL

With the introduction of its Generation 8 dozer line, Liebherr has focused on delivering the latest technology for the modern construction site. With Operator Assistance Systems options, operators are supported with the tools that empower them to move material to grade faster. Liebherr says its Generation 8 hydrostatic drive system makes these dozers ideal to outfit with advanced precision technology. The hydrostatic drive ensures smooth propulsion, free from gear changes and jerky movements. The long running gear and perfect match of front equipment to the operating hydraulics and the base machine ensures optimum grading results. The low centre of gravity enables safe operation even on steep slopes and steeply inclined terrain.

LIEBHERR OPERATOR ASSISTANCE OPTIONS

Free Grade for active blade stabilization during fine grading. This tool simplifies and saves time in the creation of level surfaces, ramps, dams, and fine grading. It continuously displays the current blade inclination and the position of the dozer using two sensors that capture the blade height and inclination.

Definition Grade for automatic blade positioning when creating simple 2D surfaces. This eliminates the need for additional equipment to create horizontal or inclined planes on small- to medium-sized construction sites such as landscaping sports fields, roads and parking lots, and construction of

industrial and commercial facilities. Two sensors capture the height and inclination of the blade. The Liebherr control unit computes the signal and automatically controls the lift and tilt of the blade using the operating hydraulics. The operator just needs to steer in automatic mode.

3D Grade from Topcon as optional GNSS machine control for modelling complex terrain forms. 3D Grade delivers automated 6-way blade control and exact position of the blade relative to the terrain model. In addition, the option is available to order as factory installed ready-kits, which allow a range of machine control systems from Trimble and Leica to be retrofitted in the field. 3D Grade is for creating large grades and complex three-dimensional surfaces suitable for medium to very large construction sites such as road and railway construction, landscaping golf courses, constructing large industrial facilities, and earthworks and landfill construction. Antennas mounted on the cabin roof receive signals from several GPS or GLONASS1 satellites to determine the position of the blade. A base station is required to achieve accuracy. Measurement data is transferred to the control unit which processes signals from GPS receivers, tilt sensors, and base stations, and compares them with stored default values from the site model. It controls the lift and tilt of the blade automatically through the operating hydraulics to create a profile that corresponds to the terrain data.

HIGHLIGHTS OF CAT’S NEW D10 9

aterpillar has revamped its iconic D10 dozer and says that this new design is up to six percent more efficient than the D10T2. Here are 9 highlights of this earthmoving beast:

1 The D10’s Cat C27 engine maximizes the material moved per litre of fuel. This engine switches power settings based on travel direction to offer up to 20 percent more power in reverse, reducing cycle times.

2 A new torque converter design with stator clutch frees up the stator when torque multiplication is not required – improving drivetrain efficiency. During high-load and retarding conditions, the stator clutch locks without the operator’s input.

FIRST LOOK

JOHN DEERE’S PROTOTYPE 850 X-TIER HYBRID E-DRIVE DOZER

At CONEXPO-CON/AGG 2023, John Deere Construction & Forestry displayed the prototype of an upcoming addition to its dozer lineup. The 850 X-Tier is a hybrid diesel-electric dozer that John Deere says provides greater pushing power from the torque that its E-Drive system provides. According to Matt Goedert, solutions marketing manager, John Deere has been working with this technology for over a decade since introducing the 644 X wheel loader in 2013 and the 944 X wheel loader in 2015.

The two big benefits of hybrid technology are fuel savings and a boost in productivity. When operators need to move material from point A to point B, they need to do it as efficiently as possible, and the high-torque of John Deere’s E-Drive delivers more pushing power to the ground.

Goedert adds that customers will feel a significant difference in cut and carry applications where the machine is put under high load. The machine will keep pushing and will carry material quicker. When operating in applications with light to moderate loads, such as during fine grading or spreading, customers

will experience fuel savings compared to a traditional dozer. The electric drive puts less parasitic load on the engine and enables the engine to run at a lower rpm, improving fuel economy and reducing noise levels.

The 850 X delivers 225 hp (168 kW); has an operating weight of 47,578–51,365 pounds (21,581–23,299 kg); undercarriage configurations include XLT, WLT, and LGP; and blade configurations include Power, Angle, Tilt (PAT) and Outside Dozer (OSD). These preliminary specs may change when the dozer goes to market.

According to Goedert, “We are currently accumulating hours and

3 The D10 cab offers a quiet work environment with minimized vibration and features a new touchscreen display.

4 Dual-tilt and automated blade assist (ABA) are standard technologies that automate blade movement to preset load, carry, and spread positions.

5 Optional technologies include: AutoCarry, Cat Grade Control 3D, and automatic ripper control.

6 The D10 can be operated remotely when outfitted with Cat MineStar technology including MineStar Terrain and MineStar Command.

7 Major components including the powertrain and frame are designed for rebuild using new, remanu-

undergoing extensive testing to ensure the machine performs and exceeds customer expectations to provide the most value possible. Throughout the development process we have held multiple customer advocacy groups. We’ve brought many customers into our factory to gather feedback and ideas, tune the performance, and ensure we hit the mark in all areas. We are excited to launch the 850 X into the market soon after all testing is completed.”

DEVELON DEBUTS SECOND DOZER

DEVELON first entered the dozer market in the summer of 2022 with a DD100 which was introduced under the former Doosan Infracore brand. Fast-forward to 2023, and the company has rebranded its first dozer under the DEVELON name and has debuted the second model in the lineup: the DD130.

The DD130 follows the smaller DD100 as a machine designed for fine-grading applications in residential and light commercial construction applications, according to DEVELON.

“The new DD130 dozer will build on the success of the DD100 with many of the same popular features,” says Moo Young Park, engineering manager at DEVELON. “The feedback from our dealers and customers after the launch of the DD100 was very positive, and we hope to continue the momentum with the larger DD130 dozer for the North American construction industry.”

DEVELON designs its dozers with a focus on visibility to the blade. The front engine compartment has a narrow design, the precleaner is tucked into the engine compartment, and the electronic cooling system is in the back of the dozer to improve forward visibility. A rear-view camera is standard and viewable via a full-colour, eight-inch display.

The new dozer has a six-way variable-angle pitch blade available in two sizes: the standard 4.6-cubic-yard blade or the optional 5.5-cubic-yard blade. The blade moves freely to lift, tilt, and angle. Two-way mechanical adjustments can change the blade pitch to control how steeply the blade will dig into the ground. Operators can adjust the blade pitch from 52 to 58 degrees and can quickly remove materials stuck to the blade using the blade shake function.

All DEVELON dozers feature the piping to fit an optional ripper attachment; the ripper’s parallel linkage helps maintain a consistent angle to the ground, regardless of height. A towing drawbar is also available.

The DD130 utilizes an electronically operated tilting cab that provides access to internal components. Even with the cab tilted, the dozer can be started while the machine is being diagnosed or repaired.

DEVELON designs its dozers with a focus on visibility to the blade.

An in-line pre-cleaner helps improve filter life and is integrated with the air cleaner. It’s also more compact to fit in the smaller engine compartment. Self-cleaning and maintenance-free, the intake system can expel a variety of debris, including mud, snow, leaves, sawdust, and chaff. The dozer undercarriage is designed for easy maintenance access. A removable side panel provides access to an area to add grease to the undercarriage’s tension system.

Telematics is standard, and DEVELON’s dozers are compatible with available 2D grading systems.

USER-FRIENDLY AUTOMATION DRIVES INCREASED CRUSHING EFFICIENCY

BY JARROD ADCOCK

Plant systems integration and crushing circuit automation continue to grow, expanding quickly in capabilities over each passing year. For some users, adapting to a new cone crusher automation program fuels fears of frustrating learning curves, operational failures, and troubleshooting headaches. But the right automation program is designed with true simplicity and safety at the forefront.

From a simple set-up to safe start-ups and shut-downs, crusher automation systems should be easy to install, easy to understand, and easy to monitor by any member of the quarry crew. Most importantly, optimum automation ensures safe, reliable, and profitable material processing.

USER-FRIENDLY COMMUNICATIONS AND SIMPLE SET-UP

Look for an automation system with a simple, user-friendly sensor communication network.

Older systems may feature dozens of separate conductor wires running from the PLC to each component, resulting in a complicated and time-consuming network to set up, and a major hassle to maintain over time.

A simple sensor communication network accesses a standard 4-wire cable system from the cone crusher to all auxiliary systems. It’s a quick, easy set-up that streamlines diagnostics and troubleshooting while minimizing the downtime associated with common

conventional systems.

A major advantage is safe control of motor starts and stops with one touch on the screen. This ensures that the crusher is always safely starting up and shutting down in the proper sequencing (without operator intervention) to protect machine performance. A one-touch start and stop feature eliminates the need for an additional box for electrical push buttons in the tower.

For a safe start-up, the automation system will monitor the lubrication system for proper temperature and flow before allowing the crusher to start up – and, should an event occur, it will automatically shut off the crusher as well as the crusher feed.

For a safe shut-down, the operator hits the one-touch stop feature and proper sequencing automatically starts with shutting off the feed, followed by the cone and the discharge. The lubrication will run for an additional five minutes until all the oil flushes through and the cone comes to a complete stop. At that time, the lubrication system will shut down. Notably, the system tracks how long it takes the crusher to shut down, from full rpm to a full stop. By tracking shut down times, operators have a way to help diagnose abnormal bushing wear.

AUTOMATION PROVES BENEFICIAL IN FIELD USE

In both portable and stationary operations, user-friendly automation systems are impacting crushing efficiency and ensuring lower operating costs per ton.

Safe control of motor starts can be done with one control on a touchscreen, ensuring the crusher is always starting up and shutting down in the proper sequence, safely and without operator interference.

The latter has proven true for one contract crusher who is operating a Superior Industries Patriot P300 Cone Crusher Plant, equipped with Superior’s Vantage Automation System.

According to Matt Voigt, Superior Industries product manager for portable plants, the crushing plant combines a 225-kW cone, a triple-deck screen, and seven feed and discharge conveyors – all on one chassis and configured for both

open and closed circuits. The plant also features new “Level-Assist” technology as an innovation that further streamlines crushing plant portability.

Voigt explains that after lowering the hydraulic cylinders to get the plant to the desired operating height, the level-assist system automatically levels the plant. “One worker can get the job done in less than five minutes. It saves a lot of time in set-up,” he adds.

As to automation on the portable plant, Voigt stresses that the Vantage Automation System monitors all the vital functions of the crusher.

“It’s simple, easy to use, and acts as a warning system that alerts operators to conditions such as bowl float, excessive amperage or temperatures, and lubrication issues,” he says, adding that, “since it’s built completely in-house, the system is more affordable, and offers the user a one-call service and support package.”

On older crushers, Voigt says that

maintenance crews had to constantly rely upon gauges to monitor operating parameters. “Also, it was such a hassle to change settings on older crushers, causing crews to check the settings less often than necessary,” he says. “Today, crews operate the new plant from a touchscreen control panel that allows them to easily adjust crusher settings, or to start and stop the plant in sequence with the push of a button.”

Quarry, operating an automated Patriot P500 Cone Crusher, reports a decrease in operating costs and an increase in plant uptime. The plant’s processing team likes several of the automation system’s features, particularly the simplicity of the sensor communication network, which accesses a standard 4-wire cable system from the cone crusher to all auxiliary systems. Other benefits include the capability of making setting adjustments on the fly, which gives them greater flexibility regarding changes in material feed, and allows them to easily tweak processing within all circuits of the plant.

Tulsa Rock Processing Engineer Mike Neal says that the automation system’s auto-feed function is one of the biggest advantages. Regardless of changes in the feed, the system will always maintain the desired material feed levels in the cone, while also maintaining the desired amperage on the motor to ensure optimum crushing efficiency.

The right automation system is all about simplicity. End users should find there’s nothing to fear and everything to gain – including peace of mind and optimum crushing performance.

Three choices for successful screed selection

BY LEE TOOP, EDITOR

When paving, the last point of contact between the paver and the final product is the screed. To do the job properly, the screed needs to place mix at the right thickness, on the right slope, and with the right surface texture.

Most screeds on the market for smaller commercial projects, like parking lots, road repairs, and driveways, are similar in design and function. You have several decisions to make when choosing a new screed to ensure that the final product meets the needed specifications.

FRONT OR REAR MOUNT MAKES A DIFFERENCE

Mount style is a key choice when selecting a new screed. There is no right or wrong answer to whether a screed should be front- or rear-mounted because it all comes down to the needs of the job, says Brodie Hutchins, vice president, dealer development with Wirtgen America.

On a front-mount screed, the extensions are placed ahead of the main screed, which allows for easier hydraulic retraction and reduces the likelihood of material being caught in moving parts.

“A front-mounted screed has a much smaller pile height so that if you’re coming up on a mailbox or a fire hydrant or some other obstacle, it’s much easier to pull it in because the volume of material in front of the extension is lower,” says Hutchins. “If you back up to do a driveway, you hit the button and the mix goes all the way out, then at the end, you pull it in, you won’t have that big pile on each side from the rear-mounted extensions.”

Rear mounts are often better for larger contracts such as roads and parking lots, where the extensions are not being moved as frequently and there are fewer obstacles to avoid. There is a smooth, natural flow of material from the paver to the screed, allowing for easy placement. Rearmount units are also a larger structure, providing more weight and compaction.

In addition, rear mounts almost always feature the same depth of plate on both the main screed and extensions, making it easier to ensure a consistent texture across the mat. Hutchins explains that front-mounted extensions are not as deep as the rear-mounted extensions or the main screed, requiring additional angle adjustments.

Whether front or rear mount, almost every screed on the market today is variable width. Fixed-width screeds, used most frequently in large highway and road jobs, represent only a small percentage of machines in use. The trend for pavers has been toward versatility, and variable-width screeds play into that demand, Hutchins notes.

VIBRATION OR COMPACTION OPTIONS FOR COMMERCIAL SCREEDS

Asphalt screeds take material coming through the paver’s augers from the hopper, spread it out, and smooth it down using heated screed plates and the machine’s weight. They also add slope and contour where needed and prepare the mat for compaction by rollers following the paver.

Vibration is the most common way to smooth down the asphalt mix, though some commercial pavers are available with compaction tools as well. Smaller units are generally fitted with vibratory systems that use an eccentric on the main screed and extensions. This shakes the plates enough to help spread the material and leave a smoother surface.

You can also consider screeds equipped with tampers if you need a little more compaction from the paver.

“We sell several models with a tamper screed – it has a tamper bar in front of the screed plate that compacts the material and then smooths it, versus just smoothing it and getting on to it with the roller to do all the compaction,” Hutchins says.

The tamper strikes the surface of the asphalt, pushing the material down, then the screed passes over the material with its usual vibration to leave the needed texture and allow easier final compaction.

Manufacturers are expanding the use of automation and other technology on asphalt screeds, reducing the number of manual inputs required from operators to ensure precision.

TECHNOLOGY EXPANDS ON SCREEDS

As technology matures in the roadbuilding sector, more new features are becoming available for screeds. Advanced 3D control systems and a range of automation tools to help you do your jobs more smoothly.

Screeds have moved away from old-style controls like toggles and switches to new, easy-to-read operator panels that are popular with new users. Touchscreens make it easier to program grade and slope and are central to automating many parts of modern screeds.

“There is more exploration into the use of true three-dimensional set-ups where contractors can equip the machine to not only steer but also set the depth you’re paving and the slope,” Hutchins says. “From a practical standpoint, we’re trying to automate more of the functions on these machines to prevent operators from making so many adjustments on the fly.”

Telematics is growing in use on pavers and screeds. Hutchins said there is a demand for data among paving contractors, and today’s machines feature communication between the plant, trucks, paver, and rollers to track all aspects of a project.

“It’s really a dialed-in process where contractors know the exact tonnage in a day, how many trucks they need, how far the trucks are from the paver, and other factors so they can theoretically calculate how fast they should be paving all day long,” Hutchins explains.

KNOW YOUR CREW FOR SUCCESSFUL SCREED SELECTION

While you may be able to track all the hardware variables when it comes to selecting the right screed for your work, there is one final factor to keep in mind: the crew.

Paving equipment requires a good team to operate, and successful paving requires the crew to know the equip-

ment well. It is important to know what type of screed your team prefers for the best results, Hutchins says.

“Crews have very strong opinions on what tools they want to use for the job. If a crew is used to working with rear-mounted screeds – don’t give them a front-mounted screed,” he advises. “They want what they’re used to. It’s like they’re artists – they’re painting a picture, and they want to do it their way.” HEG

DYNAPAC ELECTRICALLY HEATED SCREED FEATURES EASILY ADJUSTABLE VIBRATION UNITS

The TH E screed, available on all Dynapac tracked SD Highway pavers, is designed to combine ease of use and efficiency for a range of tasks. TH E stands for: Tamper, High compaction, Electrically heated. All TH E screeds come with a special high compaction system in each section that combines static hydraulic pressure with a high amount of kinetic vibration energy.

High frequencies ensure vibration can reach throughout the paved mat, while maintaining the machine’s energy consumption. A maximum compaction of 3,000 rpm and max pressure of 1,015 psi (70 bar) aid contractors in achieving optimum results. While conventional tamper vibratory screeds have a fixed vibration unit on each section, the TH E vibration unit is not directly connected to the mainframe. Instead, the unit can be freed up to allow for fine-tuning and adjustment that ensure vibration is impacting precisely where it needs to. By creating high vibration frequencies and simultaneously reducing impact pressure, operators and crews can compact all kinds of material.

The Dynapac TH E system offers features, such as stepless adjustable hydraulic pressure and adjustable vibration and tamper rpm, that ensure the machine can be set for job site conditions.

A large, intuitive control screen gives operators direct and easy access to all compaction controls for quick adjustments, leading to uniform and high pre-compaction levels that can save roller passes and improve overall efficiency.

Intelligent automation means TH E screeds are always operating well with the paver. An intelligent lift system ensures that High Compaction Units (HCUs) are at the right pressure level. When the crew puts the screed into a floating position and starts paving, HCUs are automatically lowered to interact with material at the pre-adjusted pressure setting. Once paving stops, pressure is immediately removed, avoiding marks in the paved mat. When paving starts again, pressure is returned gradually, based on the operator’s pre-existing settings, ensuring a continuous and uniform result. And, when the screed is lifted out of the material after a paving job, the HCU hydraulic cylinders automatically shift into transport position for easier cleanup.

In addition, the TH E screed has a hydraulic crowning feature, as well as an integrated additional static hydraulic pressure setting per screed section. Basic width for the system is 16 or 19.6 feet. Mechanical extension boxes with hydraulic quick coupling systems are also available.

TH E SCREEDS FEATURE VIBRATION UNITS THAT CAN MOVE TO PRECISELY TARGET COMPACTION.

THE BASICS OF CHARGING ELECTRIC CONSTRUCTION EQUIPMENT

YOUR COMMON QUESTIONS

BY LARS ARNOLD

As more electric heavy equipment hits the market, more people have questions about it – especially related to charging. The best way to learn about and get more comfortable with this new technology is to see it in person, but in the meantime, perhaps these answers to the most common charging questions can help.

WHAT TYPE OF CHARGING INFRASTRUCTURE DO I NEED?

For optimal charging time, it’s strongly recommended to have a 240-volt, Level 2 AC charging setup utilizing an SAE J1772 charging adapter or J plug – the same as for electric vehicles. This is not difficult to install if you don’t already have one.

You can also charge with a common household 120-volt outlet, but it will take longer. Basically, the more power you can put into your machine, the faster it will charge. Think of it like filling your vehicle using a fuel pump versus a gas can.

WHY DO SOME MACHINES TAKE LONGER THAN OTHERS TO CHARGE?

Usually it’s because they have a different number of battery packs.

ARE THERE CHARGING OPTIONS FOR REMOTE LOCATIONS WITHOUT A POWER GRID?

Yes. Beam offers a solar charger that is an off-grid, free-standing option, and the great part is that the solar panels are always at the correct angle because they follow the movement of the sun. Also, two North American Type 1 charging plugs – the same used for electric vehicles – are available for 240-volt charging. The charging time is the same as on the 240-volt, Level 2 AC setup, but keep in mind that this is totally off-grid, so you don’t need power cables running to it. You can simply charge using the power of the sun.

WHAT OTHER CHARGING SOLUTIONS ARE THERE?

An option Volvo CE is working on is a Benning DC fast charger. This charges 48-volt batteries directly with 48 volts and up to 360 amps. As a result, charging times are drastically reduced. The Benning unit isn’t off-grid, so it would need to be wired into a three-phase power grid at the location where you want to charge.

At this stage in electric machine development, various OEMs and partners are working on a range of solutions, so there will be even more options in the not-too-distant future.

WHAT IS THE BEST CHARGER FOR A BATTERY’S LIFESPAN?

The best for the battery life is Level 2 AC charging, which is slow charging, versus DC rapid charging – but it’s all about a customer’s needs. Fast charging won’t kill the battery, but you can extend the life of the battery with slower charging. We don’t yet know how long the batteries will last in electric construction equipment because the technology is so new, but we estimate that the battery will likely last somewhere around 10 years.

Another thing to keep in mind is that lithium-ion technology is far superior to the old lead–acid or nickel–cadmium technology we sometimes have in mind when thinking about electric vehicles. Li-ion batteries have no memory effect and they’re maintenance free, rapid charging is possible, and they experience less loss of power in cold temperatures.

HOW CAN I ENSURE CHARGING IS MAXIMIZED ON A LITHIUM-ION BATTERY THROUGHOUT THE DAY?

First, during any pause in your workday, go ahead and charge it. A final tip is not to run an electric machine at full throttle all the time. You don’t often need the excessive power anyway.

DO OPERATORS NEED TO REMEMBER TO TURN OFF ELECTRIC MACHINES THROUGHOUT THE DAY TO SAVE BATTERY LIFE?

No. Most compact electric machines come with auto shutdown, so if an operator stops running the machine, the electric motor turns off. It’s not like a diesel engine where if you stop working, it goes into idle and burns fuel. Another benefit is that the lighting on these machines is usually LED, so they’re very low power consumers.

HOW LONG DO THE BATTERIES LAST IN A TYPICAL DAY?

This is tough to answer because electric machines can be used in so many ways in a variety of applications. Job site environments can significantly alter how long the batteries last. Right now, a lot of the models available tend to last around 4 to 6 hours.

WHAT’S THE OUTLOOK ON U.S./CANADA CHARGING INFRASTRUCTURE DEVELOPMENT?

Currently, charging infrastructure development is primarily driven by electric vehicles (EVs). As more electric vehicles come out, better charging infrastructure will become available. Electric isn’t a fad – it’s here to stay. We can expect charging infrastructure to remain a top priority for the EV industry, construction industry, and more. And of course, manufacturers and their partners will continue to research, develop, and provide a wider range of charging options in the coming months and years.

THE LAST LINE OF DEFENSE

HOW RODRADAR IS SET TO REVOLUTIONIZE EXCAVATION SAFETY

BY KEN SINGER, PUBLISHER

The dangers of utility strikes are well known, yet even when taking the most proactive measures, they can still happen – and result in potentially dangerous, even fatal, consequences for operators as well as project delays, immense liabilities, and disruption of services. The Common Ground Al liance estimates that damage during excavation to underground utility infrastructure costs the global construction industry billions of dollars annually.

RodRadar, an Israeli-based construction technology compa ny, has developed and put to market a unique bucket and in tegrated ground penetrating radar (GPR) technology platform that automatically detects underground utility infrastructure in real time, on location, and without the need for expert analysis. The operator can view all information from inside the excavator cab. The Live Dig Radar (LDR) system is the first GPR system integrated directly into an excavator bucket, allowing an operator to scan below ground quickly and easily for utilities.

I spoke with Moshe Dalman, CEO and co-founder of RodRa dar, and Yuval Barnea, the company’s VP of sales and market ing, in March at CONEXPO about the LDR technology, its devel opment, applications, and future of what has been described as the “Holy Grail” of earthmoving.

MAKING UTILITY STRIKES A THING OF THE PAST

“RodRadar’s mission is to make the $100 billion annual cost of utility strikes around the world a thing of the past,” says Dalman. “Our approach is completely different from anything else you see in the industry. We’re enabling the operator to see into the ground and have a tool that enables them to avoid utilities.”

While GPR, of various forms, has been used on construction sites since the early 1980s, the data and imaging it produces typi cally requires an expert’s interpretation. RodRadar’s LDR system uses advanced algorithms to classify radar echo and determine utility location and depth. Capable of detecting any man-made material, including plastic (PVC) and metal, to locate gas, elec tric, water, fibre optic, or telephone lines in any soil type.

In its initial development the RodRadar team had to reinvent GPR “to detect very shallow targets [utilities] in any ground condition, as well as to remove the interpretation from the ra dar. We wanted to give the operator the information and act on

it immediately. Our algorithm is targeted to give a very simple response: is there or isn’t there a target [utility pipe] and where is it?” explains Dalman.

The primary goal of RodRadar is to provide immediate and actual information that is acted on at the job site in real time. Current systems for surveying have limitations. “In ground conditions which are very challenging [the operator] might not see all the utilities, even when a job site has been scanned and surveyed conventionally, and is accurate, at the end of the day there are always utilities that can be missed. There is always information that is incomplete. Even when the locations are known, the operator can still hit them; we are the last line of defense,” says Barnea.

“Contractors are very innovative. Once you give somebody a good tool, they understand very quickly how to use it,” adds Dalman.

Aspen, Colorado–based contractor Shay Stutsman of Stutsman & Gerbaz Inc Earthmoving – one of RodRadar’s first North American clients – understands that there is a constant knowledge gap in terms of where underground utilities are located. Stutsman has his LDR system on an excavator equipped with a grade control system; when an unmarked utility is discovered, they register the GPS coordinates and know where the utility is located. Stutsman recounted that when they got the Live Dig Radar unit, “A guy from the Aspen municipality saw what they were doing with it and said: ‘I am not going to hire anyone else unless he has the Live Dig Radar.’” Stutsman understands the impact of technology. With LDR you can finally see into the ground, and this completely changes excavation.

HOW TO OPERATE LIVE DIG RADAR

To use the system, the operator positions the bucket at the starting point of where they plan to dig. The bucket is positioned in front of the dig location and moves toward the excavator over the area to be scanned. With the push of a button on the touchscreen, the LDR scans the earth for buried utilities as the operator slides the bucket along the ground. The in-cab LDR Visualize Monitor then displays a utility’s distance and depth of utilities in the area where excavation is required. Alerts are sounded when utilities are detected, and a message on a red background of the monitor signals across the screen announcing, “Utility Detected.” The system uses advanced algorithms to classify radar echoes and identify the utility.

As with any other GPR system, LDR’s digging/visualizing depth is affected by soil conditions. Dalman explains, “In perfect conditions, like dry sand, it’ll detect up to a metre, a metre and a half. In wet clay, it’ll detect up to 40 to 50 centimeters. One of the things about this system is that it’s not a mapping tool, it’s not a surveying tool – it’s a job aid. It’s a tool to avoid hitting utilities. Like with any other tool . . . you have to adapt the way you operate it to the conditions of your job.”

In applications that require more depth in excavation, operators are able to dig in layers, scan, and then dig again.

RODRADAR PARTNERS WITH AMI

RodRadar was able to make the electronics and antenna in the bucket very rugged and sustainable. “We have collaborated with high-end bucket manufacturer AMI, known for its high-quality attachments, to build the perfect envelope that can

both operate and protect the sensor. AMI is a perfect example of a company that understands they’re not just selling steel but they can sell technology,” says Dalman

RodRadar and AMI have developed three bucket sizes outfitted with LDR that have bolt-on cutting edges:

• Type I is for excavators weighing 3,000 to 10,000 pounds and comes in widths of 18 or 24 inches.

• Type II is for excavators weighing 10,000 to 24,000 pounds and comes in widths of 18 or 24 inches.

• Type III is for excavators weighing 24,000 to 45,000 pounds and comes in a 24-inch width.

WHERE RODRADAR GOES NEXT

Dalman sees opportunities to integrate its technology with OEM machine control systems that are on the market, similar to how the ADAS (Advanced Driver Assistance Systems) is used in the automotive industry, to improve the ways in which the operator is working but that no one sees on the ground. “We are in a unique position where we can integrate with everybody and everybody has a collective interest to integrate with this technology,” says Dalman.

Dalman adds that the other significant future opportunity for RodRadar is to use the information found in the data collected by the Live Dig Radar system and to add more capabilities.

“For example, what type of utility is being located, what’s the direction of the utility, even given an exact location. Just imagine the city of Montreal: somebody does something,

If it’s an electricity line, the electricity company wants to know that their line is over there because the information they have is not up to date. We will be able to do a lot on the data side to leverage all that information.”

Data capturing and management is a big part of RodRadar’s future strategy, as Dalman explains: “We want to give value to the operators, to the contractors, to the municipalities, and everybody in the value chain who could use the data collected
