Why these reviews are different

ne request we’ve received consistently over the years is “can you give us a Consumer Reports-type of review on construction equipment?” For years, our answer was no. We loved the idea, but we didn’t have the staff or extended amount of time required it would take to use that excellent publication’s model. We came to realize what we did have, however, was the Equipment Data Associates database. This tells us exactly who has financed what and on what date, giving us a direct path to owners of specific models. We could further sift that database against our Equipment World readers. Instead of experienced engineers, our reviewers are experienced owners, as verified by EDA. They weighed all of their options and chose a particular model. They then paid some of the hardest-earned money around on that machine – with the sole purpose of making more money. And then they put it to work on their bread-andbutter jobs. There’s no new-cab smell in these reviews. The paint has worn off the bucket and the floor has seen plenty of muddy boots. In fact, the reviewers of the three machines highlighted in this issue have put an average of 1,172 hours on these units. Since no one is standing by with a clipboard, our reviewers tell it like it is. They love what they love and call

out the things they don’t. They gave us scores on more than 30 attributes – such as hydraulic horsepower and breakout force – ranking serviceability, performance, operator features, machine options and their dealer experience. And they answer the ultimate question: after their in-the-dirt experience would they recommend this machine to others? The good news for manufacturers, at least in these three reviews: they definitely would. On a scale of 1 to 10, no one scored less than an 8. What you see here in print is the summary; on equipmentworld.com/reviews, you can delve deeper in what each reviewer said. How did a California backhoe service contractor, for example, score the Case 580 Super N compared to an Indiana excavating contractor? This is the launch of a new initiative for us; one we will take to other machines. But a key component is your input. First, what do you think about how our reviewers scored these machines? Agree? Disagree? Have a point they didn’t make? Go on our site and add your comments. Second, raise your hand if you’d like to review a machine in your fleet. These reviews are by our readers for our readers. The more machine owners contribute to these surveys, the more valuable the evaluations will be. That helps everyone make informed equipment decisions, and opens up a whole new forum for discussion with your peers and manufacturers.

Infrastructure forum spotlights need for funding solution

he need for updating and maintaining U.S. infrastructure work is a clear, agreed-upon issue, but the means of providing funds is still divisive, as evidenced by an infrastructure forum put on by the National Journal. Transportation Secretary Anthony Foxx and House Transportation and Infrastructure Committee Chairman Bill Shuster (R-Pa.) discussed the need for continuous funding, but did not address how the Obama Administration and the Republican majority could break the methodology impasse. Foxx touts the plan for tax reform, including repatriation of domestic companies’ foreign profits, as a means for funding transportation projects. Shuster says that’s not a “possible”

solution. Many are calling for an increase in the gas tax – which hasn’t increased in more than two decades – but such an increase is quickly drifting to the wayside as a solution. However, both made it clear that both sides are committed to coming up with a solution. “I feel confident that we will do a long-term bill, a five- or six-year bill,” Shuster said during the forum, “because both sides of the aisle, both sides of the Capitol, both ends of Pennsylvania Avenue, everybody’s talking about a long-term bill.” “The one bright spot is that folks like Chairman Shuster aren’t just aware of this problem; they’re committed to solving it,” Foxx said. “Not just with regard to surface transportation, but with regard to rail and to avia-

tion reauthorization. And I very much look forward to working with him on all of those issues.” – Chris Hill

Construction expected to near prerecession employment highs by 2022

onstruction employment will likely grow by 29 percent between 2012 and 2022, according to a report by the CPWR Data Center. According to the center, that would put the number of construction workers in the U.S. at 11.5 million, just under the industry record set in 2007 before the recession took hold. Funded by NIOSH and using date from the Bureau of Labor Statistics, the data center, which is a non-profit research and training institution created by the trades unions, reports that although 2014 construction employment was still below the 2007 level, new hires outweighed job losses last year. Monthly hires outweighed job separations by approximately 25,000 jobs per month in 2014. Construction employment has reached its highest level in six years, with 9.8 million workers in 2014 compared to 8.9 million workers in 2012. Hispanic workers made up approximately 60

percent of this growth, adding a half-million jobs over a twoyear period. Although construction employment overall has improved since the economic downturn, growth levels have varied across construction occupations. Power-line installers experienced the highest percent change in employment at 63 percent, while laborers, electricians, truck drivers and welders also experienced growth. The projected positive change in construction, at 29 percent over the 10-year period, includes a 48.2 percent increase in residential building, a 26.1

percent increase in non-residential building and a 23.1 percent increase in highway, street and bridge construction. This compares favorably to the projected change in employment across all industries, which is expected to increase by 11.3 percent over the same period. On a regional level, 68 percent of states saw an increase in construction employment between 2010 and 2013, with North Dakota experiencing the highest jump at 50 percent, and Alabama experiencing the steepest decline, falling 9 percent. Between 2012 and 2022, the most positive growth is projected for states in the western U.S., Florida and Georgia, with projected growths of more than 25 percent, and close to 50 percent in Nevada. More modest growth is expected in the northeastern U.S., with just 3 percent growth projected for Maine. – Amy Materson

Briefs Holcim-Lafarge merger back on track The short-lived hold on the Holcim-Lafarge merger has ended, with the cement companies jointly stating they have “reached an agreement on revised terms for the merger of equals between both companies.” Holcim previously delayed the merger due to a disagreement of terms on the deal. The companies now expect it to close in July 2015 after the Holcim board accepts terms during their next meeting in May.mThe companies agreed on an exchange ratio of nine Holcim shares for 10 Lafarge shares, and that a new CEO, to be proposed by Lafarge and accepted by Holcim, will be appointed after the deal closes. Reitzle and Lafont will be “non-executive” co-chairmen, and Beat Hess will be vice-chairman.

EDITOR’S PICK

650K

FUEL SAVING ECO MODE Boost productivity and uptime in earthmoving and grading applications with the Tier 4 Final 550K, 650K and 700K crawler dozers from John Deere, which feature a diesel particulate filter that can go up to 15,000 before requiring ash removal. The 550K and 650K feature a PowerTech 4.5-liter diesel engine that delivers 92 and 104 horsepower, respectively, and the 700K has a 6.8-liter PowerTech that provides 130 horsepower. All three models include Deere’s Eco Mode, a new feature that optimizes fuel economy while maintaining ground speed, which is accomplished by automatic adjustment of the engine speed and the transmission settings based on the load. Deere estimates the feature will save customers as much as 20 percent in fuel costs with no loss of productivity in many applications. Additional features include a new push button throttle that controls the engine RPM, instead of a rotary dial. The throttle works by using speed increase and decrease buttons that cause the RPM to either low idle or to go wide-open throttle;

pushing and holding the button allows the operator to locate the desired speed. The hydrostatic transmissions have been updated, including improving response and controllability on the electronic control system. Instead of using two-speed motors, a variable displacement design boosts pushing power and drawbar pull. The electrohydraulic control option includes a larger hydraulic pump on the 550K and 650K, and the EH system is more responsive on all three machines. A feature with EH controls enables the operator to shake the blade in a quick, repeated motion that helps the blade release material. The open architecture design of Deere’s electro-hydraulic controls allows the operator to choose Leica, Topcon or Trimble grade control systems. The 700K has two additional blade size options – the 126inch and the 144-inch blade are now available in addition to the 120-inch blade on an XLT frame and the 132-inch blade on an LGP frame. The 700K also is equipped with Deere’s V-Cool package, a cool-on-demand hydraulically driven fan.

USEFUL UPGRADES

Caterpillar’s 735C, 740C EJ and 745C articulated trucks feature a host of upgrades over the machines’ predecessors, the B Series. With engines that meet Tier 4 Final standards, the 735C’s C15 ACERT delivers 452 horsepower, and the C18 ACERT engine in the 740C EJ and 745C delivers 511 horsepower. The trucks have 36-, 42- and 45.2-ton rated payload capacities, respectively, including a 1.7-ton increase for the 745C when compared to the 740B. The 740C EJ is an ejector model that combines the 745C’s tractor with a horizontal discharge body that enables the truck to unload material to uniform depths while traveling at speed. The ejector model also provides stability when discharging the load in less-than-ideal conditions. The trucks include Cat’s Clean Emissions Module, an aftertreatment system that includes a diesel particulate filter that automatically regenerates, and features a selective catalytic reduction system and easily accessible DEF tank. The transmission, Cat’s CX38 High Density Power Shift, has nine forward speeds and two reverse speeds. The CX38’s electronic features include transmission clutch engagement modulation for smooth shifting and torque management that maintains consistent flow during gear-range changes, while providing automatic shift selection tailored to the job. The transmission also has automatic traction control and the ability to set retarding control to fully automatic. Additional features include a system that facilitates stopping and starting on grades, and a braking system that applies the service brakes during pauses in the work cycle.

MORE HAULING CAPACITY

Talbert Manufacturing has updated their Traveling Axle Series by increasing the hauling capacity of each model in the product line by 5 tons. Set to replace all the models in the series, the new TA models now feature capacities of 40 tons for the 4048TA, 4050TA and 4053TA, and 55 tons for the 5548TA and 5553TA models. The TA Series features a 36-inch loaded deck height to allow for transportation of tall equipment through bridges and tunnels. The models also have Talbert’s piggy-back cylinder, which now has a larger diameter for faster axle travel. An increased number of keyholes across the rear of the trailer provides flexibility when tying down loads, and a lockable curbside gooseneck toolbox has a weather resistant door seal. A standard metal e-chain for air and electrical lines ensures aftermarket dock levelers can be added easily and less expensively. Additional features include a 7-degree load angle, 15,000-pound planetary winch with two-function wireless remote and double keyhole tie-down slots on top of the outside beams and recessed in the center of the main deck. 20 April 2015 | EquipmentWorld.com

AUTOMATIC ENERGY ADJUSTMENT

Perform a range of oversized breaking applications including rock splitting with Montabert’s V1800 and V2500 Evolution hydraulic breakers, which feature an automatic two-speed variation system that adjusts impact energy and striking rate to deliver high energy per blow on hard ground and high frequency on soft ground. The 4,154-pound V1800 is designed for carriers weighing between 55,100 and 66,150 pounds, has a 310- to 800-pbm striking rate and delivers 6,000 footpounds of impact energy. The 5,660-pound V2500 is suited for carriers weighing between 59,500 and 88,200 pounds, has a 350- to 800-bpm striking rate and delivers 8,000 foot-pounds of impact energy. The heavyrange Evolution breakers have a heavy-duty housing and fully enclosed heavy-duty cradles that minimize ambient noise on the jobsite while protecting working parts from dust and debris. Standard features include a blank-fire protection system, soft-start feature and an energy recovery system that recycles recoil energy to increase strike power.

SMALL-SCALE WORKHORSES

Hitachi has updated its smallest compact excavators with new Tier 4 Final engines that require no diesel exhaust fluid. The new ZX17U-5 and ZX26U-5 compact excavators, boasting 14.5 and 20 horsepower, respectively, are designed for a range of jobs including commercial and residential building, site development and rental. The ZX17U-5 weighs 3,790 pounds and the ZX26U-5 weighs between 5,870 and 6,110 pounds. Both machines feature independent swing boom and 360-degree rotation, allowing them to work in tight spaces, as well as simplifying loading and transporting the compact excavators from job to job. A standard backfill blade allows the machines to be used for grading and backfilling, as well as providing additional stability. The ZX17U-5 has easy blade-width expansion with redesigned blade extension pins, and the unit’s variable-width undercarriage and foldable blade assist with navigating tight jobsites. The ZX26U-5 features swing boom and foldable travel pedals that are easy to operate but offer foot room. Short-throw pilot levers deliver precise control smoothly with little effort. Safety is enhanced with a ROPS-certified canopy, as well as a ROPS cab option for the ZX26U-5. The redesigned cab is heated, and has a large front window for better visibility. Heavy-duty side shields protect the propel motors, boom and blade cylinders. The machine’s X-frame not only provides a stable platform, but also resists the buildup of material.

ASSET TRACKER

Simplify asset management with LoJack’s Connect for Equipment, designed to allow manufacturers, rental operations and construction companies to more easily track their equipment. The telematics system enables tracking machine utilization by week, day and hour; provides real-time and historical data, analysis and management features with easyto-use reports; and tracks service data including records and engine hours. Accessible via smartphone, tablet or laptop, the system exchanges machine-to-machine data. When used with LoJack’s Stolen Vehicle Recovery System, the telematics solution enables quick recovery of stolen equipment via the system’s direct integration with law enforcement.

CONVENIENT KIT

Construction companies, utility companies and public works agencies can warn the public about downed power lines and electrical emergencies with the Emergency Utility Marking Kit from William Frick and Company. Stored in a duffel bag, the kit contains a traffic cone sleeve alerting others to the presence of overhead work, utility pole wraps, self-laminating hard hat emergency labels, utility cable ID tags, lock-out tags, utility marker flags and danger tape to create a perimeter around the work area. Small enough to easily store in a utility vehicle, the kit is designed to be useful in areas where severe weather conditions create a need to immediately mark a hazardous location.

PROFICIENT PERFORMANCE

Case’s 570N EP tractor loader offers the same level of performance as the company’s 570N XT tractor loader, but features a maintenance-free Tier 4 Final engine. The 74-horsepower 570N EP has Case’s particulate matter catalyst that requires no fluids or filter maintenance. The 11,134-pound machine has a three point hitch and 28.5-gpm, 3,000-psi hydraulics to power rear attachments. Ride Control helps to reduce spillage and provide a smoother ride while roading, and Comfort Steer allows operators to maneuver quickly by going from lock-to-lock with only 1 1/2 turns of the steering wheel. The machine’s cab includes floor-to-ceiling glass and a climate control system to allow comfortable year-round use. The 570N EP is available with an optional 30-horsepower factoryinstalled PTO or PTO-ready hydraulic setup. Both options include a high-torque, low-speed axle to improve strength and boost performance. Other options include hydraulic and mechanical front quick couplers, auxiliary work lights, a fifth-spool auxiliary circuit for the three-point hitch valve and counterweights. Available attachments include angle brooms, box scrapers, buckets and snow blades.

PRODUCTIVITY BOOSTER

Designed for use with 6- to 26-ton excavators and backhoes, Geith’s tilting couplers provide up to 180 degrees of rotation from side to side. The rotational function allows operators to reposition the bucket or attachment without having to reposition the entire machine. Four independent locking components ensure safe operation while providing attachment retention. The front lock keeps the attachment in place in the event of an improper rear pin connection, while the rear lock and the mechanical spring system keeps the attachment in a working position in the event of a hydraulic power loss. The spring-retained locks are capable of functioning at a high level in severe applications or dirty environments. Additional features include a curved engaging plate, hydraulic cylinder check valve and a curl-to-release control system. A variable pin center design enables operators to change attachments from the cab, as well as reverse bucket orientation in confined spaces.

CONTRACTORS SHARE THE PROS AND CONS ABOUT THREE OF THE MOST POPULAR MACHINES IN THE MARKETPLACE

ace to face most contractors are brutally honest when they talk about equipment. But it has always been a challenge for us to get an objective consensus. So this year we set out to get our readers to tell us, on a scale of 1 to 10, what they liked and disliked about specific machines. The machines we chose for this inititial round of reviews – the Bobcat S650 skid steer, Case 580 Super N backhoe, and Caterpillar 336E L excavator – were identified by our Equipment Data Associates database as some of the top selling (financed) machines in the country. We also used this database to identify owners of these machines to survey. Two machines – the S650 and Case 580 Super N – are current models. The Cat 336E L was just replaced by the

Cat 336F L. All reviewers bought their machines between January 2013 and January 2014. While our reviewers were conservative with their numerical ratings, in their comments, given either anonomously or by name, they seemed satisfied with their purchases. Most indicated they would buy these machines again. Interestingly, our reviewers consistently gave dealer sales, support and service, some of the highest ratings. This is the first of a series showcasing reviews of heavy equipment. We’d like this to become a dialogue, and to hear what you think as an operator or owner. Let’s keep the conversation going. If you have experience with any of these three machines, tell us at equipmentworld.com/reviews. –The editors

hile our reviewers were a bit stingy with their numerical ratings, in their comments to us and in our surveys, many made it clear they like the Bobcat S650 and will continue to buy and use it. “I wouldn’t own any other,” said Chad Heinert, owner of Heinert Enterprises, Papillion, Nebraska. “I’ve owned Bobcat skid steers for 25 years.” Mark Halla, owner and self-described steward of The Mustard Seed Landscaping and Garden Center in Chaska, Minnesota, says he’s run just about every type of skid steer made in the last 20 years, but has settled on the Bobcat. “I think Cat machines are great, they run a little different and I would say they are the crème-dela-crème,” says Halla. “But you pay more for them and I think the Bobcat is a better value. Everything we have is Bobcat.” One reviewer who preferred to remain anonymous said: “I feel confident in our Bobcat products. We cur-

Serviceability: Overall score 7.7 out of 10 Compact machines can be challenging to work on when so many components have to fit in small space, and none of our reviewers gave high marks to any of the service access functions. Heinert in his comments singled out battery access as a particularly difficult task.

But many of the things that count – travel speed, balance and ride handling, the Bob-Tach attachment changing system, truck loading and tractive effort – all scored well. Halla puts foam-filled tires on his S650 and commented that he considers it to be an exceptionally stable machine. “We use it anytime we have a steep slope where something else might tip over – something you might ordinarily use a tracked machine on.” He also uses it for heavy lifting. “It’s a pretty strong machine,” he says. “We like the high speed, high flow hydraulics,” he added. “The reality is the hydraulics have gotten much better than they used to be.

Machine description

he Bobcat S650 is a skid steer loader with a vertical lift path and is part of the 600 series. Vertical lift is becoming more popular in the 1,350- to 2,200-pound class and the S650 is just a bit bigger than this, at 2,690 pounds. Compared to radial lift models, vertical lift machines are better at material handling and stockpiling and generally have a higher reach, which improves truck loading, especially loading to the center of the truck. Vertical lift skid steers are typically used when you have applications occurring above eye level. The S650 has a cab forward design and large windows on the side and top to improve visibility. Control options include: foot pedal, Bobcat’s Advanced Control System, or Selectable Joystick Controls. Hydraulic hoses are routed through the loader arms for protection. According to the 2014-2015 Equipment World Spec Guide, the S650 is one of the heavier models in this class and has the highest standard hydraulic pressure, 3,500 psi. Bucket breakout force has increased from 4,800 pounds last year to 5,138 in the current year’s Spec Guide. Going forward, the company is using a DPF-free Bobcat branded 2.4-liter engine. The Power Bob-Tach system enables you to change attachments without having to leave the cab. The ride control option cushions the loader hydraulic circuit to smooth out bumps in the road and prevent bucket spillage. Joystick controls (on Selectable Joystick Control machines) slide forward and backward independent of the seat, accommodating the needs of different size operators. Optional hydraulic bucket positioning keeps the bucket level when raising lift arms to reduce spillage.

Machine options: Overall score 8.7 out of 10 A quick glance at the chart indicates that almost half or better of all our reviewers opted for the more tricked-out versions of the S650. Two out of three went for the deluxe instrumentation and keyless start, hydraulic bucket positioning and power Bob-Tach. As for the power Bob-Tach, “I can’t ever imagine having one without that,” Halla says. “I’ve always thought getting in and out was the most dangerous part of machine operation and we don’t have to deal with that when changing attachments.” Halla also opted for the hydraulic bucket positioning, “But the reality is that once you’re a good operator you don’t need that,” he says. “It’s good for the new guys, though.” Which of these options are on your Bobcat S650?

Caterpillar 336E L excavator OVERALL RATING: 9.0 W ith a combined 14,000 hours of uptime with the Caterpillar 336E L and after considering every aspect of the machine’s fit in their business, our reviewers gave the excavator high marks in nearly every category. Based on their reviews, the 336E L is a machine that performs well and makes operators happy, despite a few quirks. Chris Cunningham has been running excavators since he was 16 years old. The 26-year-old operator has worked for underground utility contractor Garnto Southern of Evans, Georgia, for the past three years. Carpenter has put in 1,500 hours on the machine by himself and calls it, “the perfect all-around machine for what we do.” He said his favorite aspect of the machine is its size compared to what it can handle. “I can not only lift a structure that’s 20,000 pounds but also put it on the other side of the road,” he says. “And it’s fast. The 336 is Cat’s bread-and-butter in my opinion.” Howard Chaney of Hunter Construction Group in Moorseville, North Carolina, agrees. “It’s a bigger machine with more power that I don’t need a super load permit for,” he says. But the machine isn’t without issues, as our reviewers pointed out. One of the more common complaints was poor rear and side visibility, while one reviewer has

concerns over the machine’s performance compared to older Cat excavators in his fleet. There were concerns over fuel consumption as well. Here’s how our seven reviewers scored the specific aspects of the Cat 336E L, which has now been replaced by the Cat 336F L. All ratings are given on a scale from 1 to 10 with 10 being the best possible score and 1 being the worst possible score.

Serviceability: Overall score: 9.1 out of 10 Our reviewers gave the 336E L high marks for serviceability, though a few of them did subtract points for the machine’s ease of radiator clean out and for access to service points. One reviewer noted, “They changed the location of fuel filters to an extremely hard to reach location behind the cab. The fill port for the hydraulic pump interface is even more difficult to access to fill with 10W-30 in the sight glass. Still can’t reach boom, stick and stick cylinder eye zerk fittings without starting and moving machine. Competitors have installed grease lines to ease maintenance so they don’t get skipped by fuel guys.” EquipmentWorld.com | April 2015 31

Performance: Overall score 8.9 out of 10 All of our reviewers but one said the 336E L has met their expectations, and then some, in terms of performance. Tied for the highest-rated aspects of performance were swing speed/torque, bucket breakout force, dump height and reach, all with a score of 9.3. Among the areas of concern for our reviewers were lift over side at 8.4, fuel efficiency at 8.3 and nighttime lighting at 8.0, “The machine is equipped with a back-up camera, but no light on the counterweight to see at night-making all jobs with laborers on the ground very dangerous,” noted one reviewer. “Two lights on the counterweight can avoid the time and expense of a light tower every night shift.” Keith Brinson, the shop superintendent at J.B. Coxwell Contracting in Jacksonville, Florida, says while his operators like the machine, performance hasn’t met the firm’s expectations, though he may be zeroing in on an explanation for that. Brinson said each of the company’s four 336 E Ls are equipped with the longer stick option. “We do a lot of pipe laying and with the shorter swing radius than on the older model machines we have, some of the operators are complaining about some tipsiness in (the 336E L),” he says. “Plus, with the longer stick, we’ve lost some of the lifting capacity.” Brinson says the company isn’t dissatisfied with the machine and wants to get a 336E L with a medium stick to be sure that the loss in performance is solely due to the longer stick. “Right now we have some heavy storm drains that we’re doing so we’re really testing the limits of the lifting capacity. And right now, according to the machines’ chart, they’re doing what they’re supposed to be doing. They’re performing pretty close to as advertised.” When it comes to performance, Cunningham says the 336E L is unparalleled. “There’s nothing else around here that will run with it,” he says. “We’re in Richmond County, Georgia, doing a highway project right now and the company we’re working with is strictly Komatsu. I told one of their operators to get in the 336E L and as soon as he got out he said he wanted one.” Cunningham said the machine’s only downsides are its regen time and fuel consumption. “It has to regenerate and all that garbage and when it does, it burns a little bit more fuel. I try to regen mine during lunch, because if 32 April 2015 | EquipmentWorld.com

you don’t do that, by the end of the day it’s regenerating and you’re trying to leave,” he says. “And if you get down to a quarter of a tank and this thing starts trying to regen, you better go ahead and call a fuel truck.” Rate the performance of your Cat 336E L:

Operator features: Overall score 8.8 out of 10 When it comes to making the operator comfortable and productive, our reviewers gave the 336E L high praise. However, a common complaint about rear and side visibility brought the overall score in this category down a bit. “In a mid-size machine, contractors often need work done in confined spaces such as between fixed objects or near traffic,” one reviewer explains. “In an industry defined by safety (rather) than performance, the 336 is, what I feel, a step backwards as far as visual awareness. The previous 40-ton machines allowed for better sight of immediate surroundings. Blind spots have been increased on the 336 making the machine more dangerous to operate.” Another reviewer agrees, noting, “Operator visibility is very important. I think the blind spots need to be reduced to at least the previous generation 40-ton models. Line of sight is safer than a back up monitor.” Cunningham, on the other hand, had nothing but praise for the cab. “The cab on the Es, compared to the Ds, is 100 percent better. The seat is 100 percent better, they’ve done something different with the air conditioning and it’s better. The comfort of the whole cab is better,” he says.

Machine description

ompared to the D Series, the Cat 336E L excavator boasted a 12-percent increase in machine horsepower, 5 percent more hydraulic pressure and a 2-percent boost in fuel economy (note fuel economy may change depending on engine type, Tier 4 Interim or Tier 4 Final). As previously noted, the Cat 336E L has been replaced by the Cat 336F L, introduced at ConExpo in March last year. There are two versions, one with a 6-ton machine counterweight with a heavy duty boom and sticks, and the other with a 7-ton counterweight with reinforced extreme service boom and sticks. The 7-ton version offers a 6-percent lift advantage over the heavy duty version. An electric boom regeneration valve recirculates oil on the cylinder

The cooling system is 20 percent larger and a step platform has been added to the engine compartment for convenience during maintenance. The DPF regeneration system can be set to regenerate automatically, or the operator can choose manual regens if he’s working in areas with flammable materials.

Performance: Overall score 8.5 out of 10 While respondents were happy with the fuel capacity of the Case 580 Super N, they weren’t as impressed with its fuel efficiency or travel speed, which at 7.9 scored noticeably lower than other performance features. “We road the machine often and it’s slow on hills. A little more road speed would be nice,” Dowd says. Karr has a different perspective, however: “I like the transmission a lot; everything seems peppy. When roading in 4th gear, the machine keeps the engine rpms down and every rpm leads to wear.” Dowd also cites the hydraulics and fast cycle times. “It’s a smooth machine and I can get back into a hole with no jerkiness.”

Machine description

ntroduced in 2012, the Case N Series of backhoes represented a substantial reworking of the model. The series includes four machines: our review machine, the 580 Super N; the 580N, 580 Super N WT (wide track) and the 590 Super N. The 14-foot-class, 91-horsepower 580 Super N model replaced the 580 Super M Series 3. Notable changes to the line up included a PowerLift feature that boosts the muscle to the backhoe bucket as much as 65 percent when digging in frost, clay, or root bound soils and when lifting or craning heavy objects. Powershift H-type and Powershift S-type transmissions enable you to shift from the column. A kickdown feature is standard and what Case calls the SmartClutch lets you customize the transition from forward to reverse for smoother direction changes. The backhoe also has a ProControl anti-rebound system as an option that reduces side-to-side jerking when bringing a loaded backhoe bucket to a stop. The geometry of the loader arm was redesigned to increase breakout force and reach to the center of dump trucks along with increasing lift capacity 36 percent. 36 April 2015 | EquipmentWorld.com

Backhoe lift capacity – a key performance indicator – came in at a high 9.0 as did backhoe bucket height and reach, the push-button, electric diff lock controls and balance over stabilizers. “I’ve tried others,” says one reviewer, “and for what we do, the machine works well. We have the PowerLift, but don’t really use it.” Rate the performance of your Case 580 Super N:

INTELLIGENT COMPACTION After barely a decade, intelligent compaction still has some issues. But thatâ&#x20AC;&#x2122;s not stopping agencies, contractors, and OEMs from moving ahead.

38 April 2015 | EquipmentWorld.com

hile intelligent compaction (IC) has been popular in Europe for some time, it’s only in the past decade that it began gaining ground in the United States. As with any young technology, some matters are unresolved. There are no standardized intelligent compaction measurement values (ICMVs); OEMs are free to create their own ICMVs to measure the effectiveness of their equipment. And until very recently there was no mathematical way to directly correlate stiffness, which is measured by IC, with density, which is what agencies use to determine compliance with project specs. And while IC can be an important part of quality control, it’s not yet mature enough to provide quality assurance. Testing by traditional methods is necessary even when IC is used, but IC data coupled with traditional test results yield a much more comprehensive picture. “A nuclear density test is still required,” says Katie Pullen, brand marketing manager for Case Construction Equipment, “but if a company goes strictly off the data from a nuclear density meter, they’re not getting load-bearing capabilities. Measuring stiffness is said to be a better indicator than density and since primary metrics with IC include rebound detection and stiffness, the combined results will be more accurate and there will be a higher chance of passing if intelligent compaction is used.” Even though IC is far from fully evolved, it is a huge leap forward in compaction technology. Because of this, agencies are including IC requirements in their projects more often and OEMs are expanding their IC offerings. IC offers value right now and no one’s waiting for IC to be perfected before applying the current state of technology.

Fundamentals Steve DePriest, product specialist, Hyundai Construction Equipment Americas, says the fundamentals of IC are easy to understand. “Depending on the type of system, the information is displayed temporarily on a digital screen to provide guidance to the operator or, with advanced systems, displayed on the screen as well as stored for future evaluation and analysis.” An accelerometer continuously measures the current state of compaction. As the degree of compaction rises the value displayed on the instrument increases. When the value cannot increase any more, the operator knows the maximum degree of compaction has been reached and the compaction process can be stopped. “If no stable value is established, an analysis of the roadbed is required,” says DePriest. If compaction continues after the measurement stabilizes, over-compaction can occur. This can cause the vibratory machine to jump, which may result in damage to the compactor. The Volkel Mikroelektronic IC systems offered by Hyundai can be installed at the factory or in the field. Current compaction equipment models can be upfitted with the system at any time. Hamm Compaction Quality (HCQ) pre-wire kits are available for all H i-series soil and HD+ and HD+ i-series asphalt rollers. Kits include accelerometers, temperature sensors, a mount for the GNSS receiver, and a mount for a tablet PC. This allows the GNSS receiver and tablet computer of the HCQ system to be moved among machines, even from soil to asphalt and pneumatic tire compactors. All relevant dimensional data, such as size and type of roller and offset of the receiver to the center of the drum, are shared with the system by the machine’s computer. This ensures consistently

Stiffness and pass count are available with all rollers; asphalt rollers add mat temperature. HCQ allows communication between up to three rollers at once so operators can see others’ data in real time. Location information requires a subscription to OmniSTAR. The service provides accuracy to within 10 centimeters, or about 4 inches. “We chose OmniSTAR because of its simplicity,” says Tim Kowalski, applications support manager for Hamm. “With differential GPS you get RTK-level accuracy without the use of base stations. OmniSTAR is available anywhere, anytime the machine is running, requires no set-up, and maintains its accuracy and signal strength as the equipment moves around the worksite.” The satellite signal is retained for up to 16 hours after shut-down to minimize signal acquisition time after breaks, at shift changes, at each day’s start, or whenever there’s a gap in operations.

Talk to me It’s not enough to gather data. The data must also be shared. BCM 05, the current version of BOMAG Compaction Management, is one example of what’s available. The BCM 05 system has a touchscreen tablet PC, a lockable holder for the tablet, a USB memory stick and the BCM 05 software. BCM 05 reports conditions to the roller operator using a color-coded display and numbers. Comparisons to previous passes and to target values are indicated. Problem areas — such as those that cannot be compacted or are at risk of being over-compacted — are shown. Date and time are documented. All information can be transferred to a desktop or laptop PC using the memory stick for project management, statistical analyses, archiving, printing, and program calibration. With the addition of BCM 05 positioning software and a GPS receiver, location information can be added to the data. BCM 05 positioning can interface with a conventional differential GPS (DGPS) system and works with or without a reference station. BOMAG says the system is compatible with any currently available DGPS system. With a satellite-assisted reference

Chicago Pneumatic

The SR130D and SR130PD are Chicago Pneumatic’s largest rollers at 4.81 and 4.76 metric tons operating weight, respectively, which puts them just below the 5-metric-ton point at which IC becomes commonplace. CP does not offer IC on any of its compaction equipment.

service positional accuracy is at least 20 centimeters (less than 8 inches). “BOMAG has been working with IC since the 1980s,” says Bert Erdmann, director of engineering/product management heavy compaction, for BOMAG Americas. “The BCM 05 serves as our latest reporting vehicle for machine location, temperature stiffness and other values captured by our advanced IC systems, Asphalt Manager and Variomatic.” Communication must be both ways, says Kowalski. “Someone has to manage the system, setting indicator colors, giving names to projects and parcels, and doing all the background work necessary for successful implementation of IC. Even though it’s straightforward and comparatively easy work, it’s a big responsibility. Some customers think you simply add an IC setup to an existing roller and you’re done. There’s much more to it than that.”

From large to small to not at all Pullen says “There are many definitions of intelligent compaction. All Case compactors have a degree of intelligent compaction available on them from the factory but those systems vary in complexity based on size and type of machine application. It may be as simple as a compaction indicator on our small DV series asphalt rollers. Our full-size soil and asphalt compaction equipment is available with the more advanced intelligent compaction systems that provide rebound detection and stiffness measurements and provide guidance to operators based on real-time conditions.” Josh Steele of Sakai says, “Because not all systems are created equal, customers need to perform due 42 April 2015 | EquipmentWorld.com

Just as not all rollers have IC, not all IC is on rollers. Wacker Neuson is one OEM offering a form of IC on walk-behind compaction equipment. Their Compatec system, offered on three of their diesel-powered, reversible plate compactors, can be installed as a factory option or by the dealer or can be added to non-Compatech machines with the use of an accessory kit. The system’s eight LEDs are very bright and mounted in a location that’s protected yet still easily visible to the operator. More LEDs light up with each pass until optimal compaction is achieved. If all eight LEDs are flashing, there is an overload or over-compaction condition. “The operation is easy to understand,” says David Schulenberg, product manager for compaction products at Wacker Neuson. “Operators simply need to be instructed on how to interpret the number of LEDs that are lit.”

diligence. There are more aspects to consider than just meeting the reporting specs. IC complements jobsite analysis leading to higher efficiency of everything you do. When integrated with other smart-machine applications, IC data can show areas where more training is required, where fewer machines are needed than expected, or where production should speed up or slow down to meet quality measures.” Chicago Pneumatic is one of several OEMs not offering IC on any of its compaction equipment. “There’s not a lot of demand for it in the markets we serve,” says Paul McClendon, south central sales manager for CP. “We’re big in the rental market and oilfield services whereas IC is popular with heavy and highway contractors doing large projects.” He says IC appears mostly at the 5- to 6-metric ton rating and up on machines with rollers of 66 and 84 inches. Chicago Pneumatic’s largest model is the SR130D with an operating weight of 4.81 metric tons and a drum width of 53.9 inches. “There may come a time when the cost drops and it makes sense to offer IC on smaller equipment,” says McClendon. “If that occurs, agencies will likely start requiring IC on smaller projects. But right now municipalities are struggling to fund infrastructure using current standards. Who knows if or when economics will change sufficiently to bring IC to those projects.”

Atlas Copco Introduced at World of Asphalt last month, Atlas Copco’s touch screen tablet IC interface can be put on its CC2200 through C6200 asphalt rollers and their CA2500 through CA6500 soil rollers. The system provides real-time stiffness measurements of soil and asphalt via a drum-mounted accelerometer, while front- and rear-mounted sensors give temperature readings.

such systems, CMV measures ground response to the vibratory impact of the roller. Accelerometer-based systems, including CMV, find subsurface anomalies, such as boulders and tree trunks, up to 2 meters deep. “But accelerometer-based systems work best in granular soils,” says Bryan Downing, global sales consultant for Caterpillar Paving Products. Cohesive soils distort the response to compaction, yielding highly variable measurements. So Caterpillar developed Machine Drive Power (MDP), which relies not on an accelerometer but on rolling resistance. Rolling resistance decreases as materials go from loose to stiff and MDP uses this principle to provide compaction data. MDP can be used on all soil types (granular, cohesive, fines) because the damping effect of troublesome soils has a significantly reduced effect on rolling resistance. Measurements have less variability, giving operators greater confidence in the information provided. Because MDP works with cohesive and fine soils as well as granular it can be used on smooth, padfoot, or padfoot shell kit equipped machines. While accelerometer-based systems are “blind” with the vibration off, MDP works with the vibratory system on or off. This system functions in production mode where the amplitudes are high and the work of compaction is greatest, but also in a static “proofing” mode where the vibratory system is deactivated. This allows material measurement with minimal risk of de-compaction.

Hamm

The rooftop-mounted GNSS receiver and tablet computer of the Hamm Compaction Quality system can be easily moved from one machine to another when each machine has Hamm’s pre-wire kit installed.

Sakai

Sakai offers its CIS2 IC system on the SV540 series of soil compactors as well as the SW880, SW990, and SW770 series asphalt rollers. The system consists of Sakai’s Compaction Control Value system with a Topcon display and GPS antenna.

It’s nothing but a number “It is important to understand that an intelligent compaction measurement value is a ‘unit-less’ measure,” says Bryan Downing of Cat Paving Products. “It is simply a scale based upon a benchmark reading. It is just a reference mark. You establish your compaction targets based on the materials and conditions you are currently working and use that target as a reference.” Thus, an intelligent compaction measurement value, or ICMV, may or may not correlate with other testing devices or even other similarly equipped compactors. And an ICMV measured at one location does not necessarily correlate with an ICMV taken five days later at a new location.

machine matters | continued Another step closer At last month’s World of Asphalt, Volvo Construction Equipment unveiled Volvo Intelligent Compaction with Density Direct, an intelligent compaction system that calculates density. This is the first time IC has been able to provide density calculations and is a major development in bringing IC to maturity. The density algorithm and its use on the compaction of flexible pavement is patented by the University of Oklahoma. Volvo Construction Equipment partnered with the university on its research and has exclusive rights to commercialize the technology. The significant difference between Volvo IC with Density Direct and all other IC systems is that the Volvo system provides a calculated density value, where most other systems provide intelligent compaction measurement values (ICMV) based on calculated material stiffness. “Density Direct can reduce the need for additional core sampling for quality control and improves productivity and quality,” says Mark Eckert, compaction product manager, Volvo. “Operators now receive realtime density calculations covering 100 percent of the compacted mat.” Eckert says that Density Direct is a better solution than traditional nuclear gauge testing, which is more time consuming and provides only spotcheck results. The target density given in project specifications is entered using a calibration touch screen; that specification is typically between 92 percent and 97 percent. Density Direct runs that target percentage against a range of data including material thickness, material temperature, material mix, compactor weight, amplitude, and frequency. When calibrated against cores taken from a test strip, Density Direct is accurate to within 1.5 percent of labtested core samples, providing real-time density values over the complete pavement surface. The resulting calibration is stored for each “lift,” or element of the job and can be referenced later for improved efficiency and accuracy. For instance, if an operator is compacting a 4-inch binder on Monday, the calibration for this job could be “Lift One.” If Tuesday is spent compacting a 2.5-inch wearing, this becomes “Lift Two.” If on Wednesday the operator returns to Monday’s site to continue compacting binder the machine can be switched back to “Lift One” without recalibrating. Volvo will offer both Volvo Intelligent Compaction (Volvo IC) and Volvo IC with Density Direct in North America. The system will be available in Fall 2015. Initially, the systems will be a factory-installed option on new asphalt compactors models DD110B, DD120B and DD140B. There are plans to offer Density Direct as an aftermarket option for Volvo asphalt compactors for sale exclusively through Volvo dealers at a later date. 46 April 2015 | EquipmentWorld.com

IC basics Intelligent compaction is the use of hardware, such as accelerometers, and software to gauge the condition of compacted material, either soil or asphalt. The goal is to achieve optimal compaction with minimal passes while providing documentation of the work. Contractors benefit through reduced costs for fuel, labor, and machine maintenance and repair. Agencies benefit through longer service life of roadways, especially when IC is used for compaction of both the base and the asphalt.

HOW TWO STATES

INCREASED THEIR HIGHWAY FUNDING It’s not impossible:Arkansas and Pennsylvania successfully increase funds for highways

hen events are beyond our control on a macro level, it becomes time to refocus and think both smaller in order to accomplish big things. Such is the situation now with the Federal government and the maelstrom/quagmire of events surrounding efforts to fund infrastructure in the United States. Will the Highway Trust Fund issue be kicked down the road yet again, or will a permanent solution be realized sooner, rather than later? With such an uncertain environment, it’s incumbent upon states to either put long-term road and bridge building plans aside and hope for the best, or take the bull by the horns and come up with their own solution for financing much

needed infrastructure work and repairs. And the latter is just what Arkansas and Pennsylvania have done in recent years. At a presentation of state case studies for highway funding at the National Asphalt Pavement Association’s annual meeting in January, Craig Douglass, of Craig Douglass Communications, offered a look at the successful marketing campaign used in getting funding passed in Arkansas. Pennsylvania Asphalt Pavement Association (PAPA) Executive Director Gary Hoffman described that state’s efforts. For these two states, the focus was on a unified strategy, from start to finish, in getting highway construction and maintenance legislation passed. Their respective strategies involved research and statistics that backed up their

highway contractor | continued In today’s boisterous anti-tax environment, getting increased funding for highway construction and maintenance seems a daunting task. But organizers in these two states found that a powerful, unified message and strategy were the keys to success. message and drove the point home to the states’ residents that funding their highways was a long-term investment that would benefit each individual, in addition to the states as a whole. This meant job creation and the overall economic well being, with improved transportation for commerce, and long-term savings in the cost of driving for residents. They mostly diverted the dialogue away from making these efforts partisan in nature. The message was that improving road and bridge infrastructure was good for everyone and vital to the future of each state.

The Arkansas Example Raising taxes is never a popular move for any purpose, let alone for one as important as infrastructure, but political leaders in Arkansas found a way to get a temporary tax on the ballot, and more importantly, get it voted in by the state’s voters.

In 2011 Arkansas voters approved a constitutional amendment, known as Issue No. 1, which created a temporary, 10-year 1/2-cent general sales tax dedicated to a statewide, bond-financed highway improvement program. While it was a slight

52 April 2015 | EquipmentWorld.com

tax increase, it was “consumption tax” and did not apply to groceries or medicine. The amendment was approved by 58.2 percent of the vote. Also created was the reissuance of Grant Anticipation Revenue Vehicles (GARVEE) bonds to improve state interstates using a revenue stream that was already in place for that purpose, a similar bond program passed in 1999. In addition, one cent per gallon of the existing fuel tax was permanently dedicated to the State Aid City Street Program. This was a culmination of efforts originally started in 2009 by the Arkansas General Assembly’s Blue Ribbon Committee on Highway Finance. This temporary standing committee operated between 2009 and 2010. The state’s legislature created the committee via Act 374 of 2009 to investigate ways to pay for maintaining and constructing highways in the state. To help the committee determine needs and promote the committees recommendations, industry members formed the Move Arkansas Forward campaign. The committee took 18 months to create their recommendations. Move Arkansas Forward helped the committee conduct statewide focus groups to help the committee develop its considerations and recommendations. Douglass, who served as the Move Arkansas Forward campaign coordinator, says the focus groups allowed the general public and some interest groups to comment

on what was needed in their area. “We didn’t make any proposals in the groups,” Douglass says. “We just listened and noted local qualitative concerns that could be addressed in the issue. We then tested through quantitative survey research some of the comments we thought could be salient in the context of a campaign. One such message was that in every focus group, people wanted to feel ‘more connected’ to one another. This ‘better connecting Arkansas’ idea tested well, and was used as one of the selling points in the campaign messaging.” The gist: Move Arkansas Forward and the committee were making potential legislation to fund highway construction real for the people of the state. It had to be palatable to folks, and the campaign was working to give solid reasons why it was so important. Doing this required there to be a “credibility of the process,” according to Douglass. It wasn’t just a committee creating recommendations that made sense to the committee itself; it was having a research-driven process. “The ‘credibility of the process’ is also supported through the public rationale or ‘talking points’ which become the ‘reasons why’ the pro-

highway contractor | continued posals should be supported,” says Douglass. “The same key points determining the recommendations, should be used as the key points on why voters (or legislators) should support the issue, meaning the messaging is credible, because of its consistency, throughout the process.” An interesting strategy Douglass describes was an evolving support tactic. Initially, the Arkansas General Assembly referred to Issue No. 1 as a bi-partisan issue in that maintaining and building roads and highways was “an appropriate function of government. “Then, we moved the issue from bi-partisan to non-partisan, meaning the issue was beyond political considerations,” Douglass says. “In this process we brought together Republicans and Democrats in support of Issue No. 1. Positioning the issue as bi-partisan and then nonpartisan allowed both sides of the aisle to support the issue (without

alienating their so-called base).” Douglass says throughout the campaign, organizers touted the direct benefits to cities and counties, as well as overall economic development, with the creation of jobs being key. “We specifically showed certain areas of the state, with definable voting blocks both in numbers and ideology, what was in it for them,” Douglass added. “We did this with a graphic map of the projects in their area that would be constructed if the issue passed. Then we closed the deal by stating all this could be done ‘without raising taxes on groceries, medicine, or gasoline’ — the clincher.” The combination of the sales tax and reissuing of GARVEE funds is expected to supply roughly $1 billion in improvements to Arkansas interstates.

The Pennsylvania Example While Arkansas focused on the eco-

nomic impact of increased highway funding for repair and construction, Pennsylvania also highlighted safety and savings in transportation-related costs for the state’s residents.

Another big difference: Pennsylvania organizers needed to convince state legislators, and eventually the governor, rather than the voting public, as the proposal was going to become a law, rather than an amendment to the state constitution that required a public vote. Legislators passed the bill, and in November 2013, Gov. Tom Corbett signed into law Act 89, which was originally estimated to generate $2.3 billion for transportation plans per year by fiscal year 2017-18. By the end of 2014, the plan had already created $2.6 billion in projects by

It could happen in your state The following steps can sum up the success of the Arkansas and Pennsylvania highway funding programs: Create a development committee and support what’s needed A group of stakeholders from all sides of road construction and maintenance, from industry to government, should meet to create a list of recommendations. These stakeholders should use as much research as is available in supporting their recommendations. The group should use statistics, studies, and reports from the federal and state departments of transportation, as well as trade associations to highlight the big picture at the state level, and the at-home approach for smaller communities. Determining funding sources Increased taxes will never be popular, so a first step is to develop a way to reallocate existing funding sources. Otherwise stakeholders can recommend smaller taxes that exempt certain items, as Arkansas did, or adjustments to user fees such as what Pennsylvania accomplished.

54 April 2015 | EquipmentWorld.com

Develop a strategy and message Once a group makes their recommendations, stakeholders should from a coalition of support and create a campaign. Whether it’s a new law to be passed, as was the case in Pennsylvania, or a change to the constitution as transpired in Arkansas, the message should be aimed at both state residents and legislators. Highway improvements should be equated with safety, savings, and economic growth. These statements should be supported by the research used in developing the recommendations. Stay consistent and develop support Both Arkansas and Pennsylvania managed to keep at a minimum any bi-partisan grandstanding regarding the highway funding issue. This ties back to the strategy and message: It’s not a political issue, but rather a matter of well being and building the future. The message throughout the campaigns did not waver, and as broad a net as possible was cast to showcase how everyone in the state would be positively impacted.

highway contractor | continued The remaining funding sources are comprised of minimally increased user fees, such as a $5 registrations fee counties can enact on highway and bridge projects, and increases on surcharges for serious moving traffic violations. The effort for the law began in April 2011, when Corbett created the Governor’s Transportation Funding Advisory Commission (TFAC) to create highway work funding recommendations. The commission concluded in August that year and issued a report with their recommendations. In September 2011, the Associated Pennsylvania Constructors, a 400-member trade association for the state’s road and bridge construction industry, launched the Better Safer Roads campaign, with an accompanying website BetterSaferRoads.com. The statewide radio and television campaign promoted the TFAC’s recommendations and directed Pennsylvania residents to sign an online petition on the website to support the funding plan.

In Pennsylvania, laws are amendments to the Pennsylvania Consolidated Statutes (PCS), which is the official statutory codification created by the state’s general assembly. Act 89 amended Title 74 (transportation) and Title 75 (vehicles) of the PCS. The law did a number of things to channel funds for transportation purposes. One significant development was removing a cap on the Oil Company Franchise Tax (OCFT) over a five-year period, while also rolling into the OCFT the flat gas tax of 12 cent per gallon that had been charged at the pump. The last gas tax in the state passed in 1997 and the cap on the OCFT had been reached in the mid 1980s and had not been raised since that time.

The television ads, and more specifically the radio spots, prompted the citizens of the state to go to BetterSaferRoads.com and sign the petition to let the governor know the people wanted the funding law. The ads stated that lawmakers on both sides of the aisle were for it if the governor would get on board. The campaign touted that new user fees, much like the fees applied to the state’s Marcellus Shale drillers, would provide the funding and that it would equate to less than the cost of an extra gallon of gas per week for the average driver. “We did fairly unique marketing research,” says says APC Executive Vice President Robert Latham. “We shifted the message away from a ‘falling apart’ issue to ‘if we fund it, it’s safer for you and your community.” Latham managed the process for the Act 89 Advocacy. “We put together a unique coalition of groups including AARP and other non-traditional supporters of transportation,” he adds. “It enjoyed very great public support.” The Better Safer Roads campaign message, PAPA’s Hoffman told attendees of the NAPA meeting, was comprised of a few key points: safety for roads and bridges; convenience, reliability; savings in the cost of driving; and economic development, which, Hoffman described, appealed more to politically-minded individuals and legislators. “We have the highest number of deficient bridges in the nation,” Hoffman said. Hoffman reported that in addition to road construction and repairs, the law is now going to fund work on 558 structurally deficient bridges in the state.

Logical lifting

Removing a bridge slab calls for caution

The bottom line: A post-accident investigation determined the employer did not have load charts specific to the make and model of excavator being used, and used the load chart for a similar, but not identical, machine. Once the arm was extended, the weight of the concrete slab suspended over the side of the bridge surpassed the load capacity of the excavator. As the excavator began to slide, the operator attempted to decrease the distance of the load from the excavator by arming-in. However, arming-in the load forced the excavator past its tipping point, and the machine slid over the edge quickly.

No room for guesswork Excavators have a diminished lifting capacity when the load is over the side, so making an educated guess on load weight won’t work. Understanding not only the accurate load weight of your machine, but also the weight of the material to be lifted is crucial. In this accident, the concrete slabs being removed were

The accident: An operator was using a hydraulic excavator on a bridge demolition project. While removing a concrete slab, the operator extended the arm of the excavator to raise the load in order to clear the guardrail. The excavator became unbalanced, tipping to the edge of the bridge deck. The excavator went over the side of the bridge, falling 60 feet to the river below. Following a rescue operation, the operator was declared dead from blunt force chest trauma.

of different thicknesses, sizes and shapes, so it’s likely the operator underestimated the weight of the slab. Take the following precautions to ensure your excavator is both stable and within the guidelines of your load limit: Perform a Job Hazard Analysis. Prior to starting the project, your employer will perform a Job Hazard Analysis to determine potential dangers. Be on hand for all parts of the analysis so you will be familiar with any dangers that could arise. Use the information to safely perform the work, and don’t make changes to the operational plan that could change the dynamics of the lift, such as arming-out with a load when that scenario has not been tested. Work within machine limits. If the load weight limit is not visible in the cab, ask the foreman to pro-

vide you with a load limit chart for the machine you’ll be operating. If you are unsure of the weight of the material you’ll be lifting, perform a load test prior to beginning work. Remember, as you extend the load, swing from side to side or suspend the load over a drop, the machine’s load limit decreases. Plan your picks properly. Excavator picks should be planned to ensure the operator is able to maintain the stability of the machine while lifting freely suspended loads. The excavator should be on as flat a surface as possible, and compact. Crawlers should be on pads or cribbing, and outrigger blocking must be used. Load, load radius, center of gravity, and boom length and angle must all be determined exactly. If wind speeds are in excess of 30 mph, do not make the lift.

La lógica de la carga

Retirar planchas de concreto de un puente exige precaución

Conclusión: Una investigación posterior al accidente determinó que el empleado no tenía las tablas de carga específicas de la marca y modelo de la excavadora que estaba usando, y utilizó una tabla de carga de otra máquina similar, pero no idéntica. Una vez que el brazo estuvo extendido, el peso de la plancha de concreto suspendida sobre el costado del puente sobrepasó la capacidad de carga de la excavadora. A medida que la excavadora empezó a deslizarse, el operador intentó disminuir la distancia de la carga a la excavadora recogiendo el brazo. Sin embargo, recoger el brazo forzó a que la excavadora pasara el punto de inclinación, y la máquina resbaló rápidamente por la orilla.

No hay lugar para conjeturas Las excavadoras tienen una capacidad de carga limitada cuando la carga está de costado, por lo que no le servirá intentar un cálculo informado del peso de la carga. Es crucial entender no sólo el peso preciso de la carga de su máquina, sino también el peso del material que va a ser levantado. En este accidente, las planchas de concreto que estaban siendo retiradas tenían diferentes grosores, formas y tamaños, por lo que es probable que el operador subestimara el peso de la plancha. Tome las siguientes precauciones para asegurarse de que su excavadora se mantiene estable y dentro de los lineamientos de su límite de carga: Realice un Análisis de Riesgo del Trabajo. Antes de empezar el proyecto, su empleador realizará un

El accidente: Un operador estaba usando una excavadora hidráulica equipada con un accesorio diseñado para extraer plataformas y planchas de concreto de puentes en un proyecto de demolición de un puente. Mientras retiraba una plancha de concreto, el operador extendió el brazo de la excavadora para elevar la carga y despejar la baranda. La excavadora se desbalanceó, inclinándose sobre el borde de la plataforma del puente. La excavadora cayó por el costado del puente, unos 60 pies hacia el río que corría debajo. Después de una operación de rescate, el operador fue declarado muerto debido a un fuerte impacto traumático en el pecho.

Análisis de Riesgo del Trabajo para determinar peligros potenciales. Esté atento a todas las partes del análisis para que usted se familiarice con todos los peligros que pudieran surgir. Use la información para realizar el trabajo con seguridad, y no haga cambios al plan operacional que pudieran cambiar la dinámica de la carga, como extender el brazo con una carga cuando tal posibilidad no ha sido sometida a prueba. Trabaje dentro de los límites de la maquinaria. Si el límite de peso de la carga no se halla visible en la cabina, pídale al jefe una tabla con el límite de carga de la máquina que estará operando. Si no está seguro del peso del material que estará levantando, realice una carga de prueba antes de comenzar el trabajo. Recuerde que, a medida que extienda la carga, gire de lado a lado o suspenda la carga sobre una caída, el límite de carga de la máquina disminuye. Planifique apropiadamente la elevación de su carga. Los levantamientos de carga con la excavadora deben ser planeados para asegurarse de que el operador es capaz de mantener la estabilidad de la máquina mientras eleva libremente al aire cargas suspendidas. La excavadora debería estar sobre una superficie compacta, y lo más plana posible. Las orugas deben estar acunadas o sobre cojinetes, y debe usarse un bloqueo de acoplamiento. La carga, el radio de la carga, el centro de gravedad, y la longitud y el ángulo del brazo extensor deben determinarse con exactitud. Si las velocidades del viento superan las 30 millas por hora, no levante la carga.

road science | continued Virginia’s I-81 North America’s first highway reconstruction combining cold in-place recycling, cold centralplant recycling, and full-depth reclamation all in one project is now performing “excellently,” according to a 2015 TRB paper.1 The Virginia Department of Transportation rebuilt the section of I-81 in the shadow of the Blue Ridge Mountains in 2011. In Phase I, VDOT rehabilitated a 3.7-mile section of I-81 southbound near Staunton using cold in-place recycling, cold central-plant recycling and fulldepth reclamation. The highprofile project used cold milling machines, a reclaimer, a portable cold-mix plant and a cold recycler, in addition to rollers and asphalt pavers. The processes were performed both “in place” within the roadbed and adjacent to the highway, and contractors reused existing material from the underlying road structure. The driving surface received a new overlay of hot-mix asphalt. After rebuilding the shoulders to accommodate work zone traffic, the top 10 inches of asphalt from the right-hand lane were removed using two large cold mills, and brought to a mobile cold recycling plant near the interstate, adjacent to the work zone. There the materials were stabilized with a combination of foamed asphalt and portland 1 Initial Performance of Virginia’s Interstate 81 In-Place Pavement Recycling Project, by Brian K.

cement using cold central-plant recycling (CPR). Meanwhile, a subcontractor stabilized the revealed, existing aggregate subbase – which had deteriorated to the point of causing damage to the overlying bound layers – with 3 percent lime kiln dust, a reclaimed industrial byproduct, to a depth of 12 inches using a reclaimer. The stabilized materials were compacted in-place with padfoot and smooth drum rollers. The milled, recycled materials from the mobile cold-recycling plant then were used to pave a new base course over the stabilized aggregate subbase to a 6-inch compacted depth. This later was topped with a 4-inch intermediate course of conventional hot-mix asphalt and a 2-inch surface course of stonematrix asphalt. In Phase II of the project, a larger cold recycler performed cold in-place recycling (CIR) in the left-hand passing lane. For this work, the top 2 inches of the pavement was milled and the next 5 inches was recycled in situ using foamed asphalt and portland cement as the stabilizing agents. It then was topped with a 2-inch hot-mix asphalt intermediate course and a 2-inch surface course of stonematrix asphalt. “The section of pavement rehabilitated by the three in-place recycling methods continues to perform well after nearly three years of heavy interstate traffic,” report the authors. “To date, approximately 6 million equivalent single axle loads have been applied.

depot parking areas and dams, but its inherent roughness has made it seldom-used for highway pavements. The Virginia DOT, however, has placed its first RCC pavement and is evaluating it for performance, according to a 2015 TRB paper.2 RCC is a relatively stiff mixture

of aggregate, cementitious materials and water that is placed using asphalt pavers instead of slipform pavers, is compacted by vibratory rollers and hardens into concrete. It contains a low amount of water, exhibits no slump, and can be placed and opened to traffic in a short period of time.

“[RCC] does not contain reinforcement, tie-bars or dowels,” Hossain and Ozyildirim say. “All of these factors combine to produce a relatively low-cost roadway compared to either asphalt or conventional concrete pavements. However, such a roadway may lack the smoothness required for high-speed roadways and can experience raveling and/ or cracking.” While an asphalt overlay could remedy the smoothness and raveling issues, cracks might

In this test, VDOT rebuilt roadways leading to the Staffordboro “Park and Ride” commuter lot. Roller compacted concrete was used to rehabilitate Staffordboro Blvd. (S.R. 684) near the Garrisonville Road (S.R. 610)/ I-95 interchange and other connector roadways leading to and within

the parking lot. RCC could be constructed at reasonable cost using only night time or weekend construction, and the pavement was designed to withstand a high volume of

road science | continued heavily loaded trucks and buses, they say. Contractors paved Staffordboro Blvd. with 8 inches of RCC and used 6 inches of RCC on the rest of the access roads inside the parking lot. In order to achieve a smoother riding surface, all RCC was overlaid with 2 inches of asphalt surface course. The authors concluded that the RCC project was successful, and that RCC with strengths exceeding 1,600 psi at 12 hours, 2,500 psi in 24 hours and 4,000 psi at 28 days can be achieved.

Louisiana limestone/cement blends Interground limestone/cement blends are appropriate for all uses in the Pelican State, according to a new TRB paper.3 Portland cement concrete (PCC) is the world’s most versatile and most used construction material, Rupnow and Icenogle say, but it occupies a substantial carbon emissions “footprint.” But a new method of reducing the carbon footprint of PCC incorporates a much larger portion of interground limestone (Type IL cement) into the cement. Standards organization ASTM and the American Association of State Highway and Transportation Officials have now changed specification language of ASTM C595 and AASHTO M240 to allow up to 15 percent use of interground limestone, the authors report. The incorporation of the increased limestone content significantly reduces the carbon dioxide footprint of the resultant PCC while extending

the life of cement quarries. Use of the blend also permits cement manufacturers to make its cement “go farther,” producing more cementitious material without having to expand production facilities, thus sidestepping associated capital expenditures and environmental permitting. To evaluate the new Type IL cement, the researchers characterized the fresh and hardened concrete properties of binary (twocementitious component including portland cement) and ternary (three-component) combinations incorporating Type IL cement. “The results of this study showed that the use of Type IL portland cement in Louisiana should be allowed for all applications, including ternary mixtures up to 70 percent replacement,” Rupnow and Icenogle report. “Compressive and flexural strength results were comparable. Type IL mixtures exhibited less shrinkage when compared to the control mixtures with Type I cement. Surface resistivity results were comparable and indicated that the surface resistivity meter use will be applicable for mixtures containing Type IL cement.”

Nearly half recycled concrete in PCC pavements Replacing up to 45 percent by volume of natural course aggregate with recycled concrete aggregate (RCA) had no significant effects on any of the concrete properties studied, says TRB research.4 This indicates high-quality RCA can be used as a replacement

for a portion of the coarse natural aggregates in new portland cement concrete pavements. Variables in the study included the source of the RCA, percent replacement of coarse natural aggregate with RCA (0 to 45 percent), and percent replacement of portland cement with Class F fly ash (0 or 20 percent). RCA from all three sources met the Washington State DOT requirements for aggregates, and all fresh and hardened concrete properties met WSDOT requirements as well, they say. “The effects of RCA on fresh concrete properties were evaluated by measuring slump, air content, and density,” the authors write. “Slump and air content were controlled parameters in the batching process, with targets specified by WSDOT of 1 to 3 inches for slump and 3 to 7 percent for air content.” The effects of RCA on hardened concrete properties were evaluated by measuring compressive strength, modulus of rupture, coefficient of thermal expansion, drying shrinkage and freeze-thaw durability. “Test results showed that up to a 45 percent replacement of coarse natural aggregate with RCA had no significant effect on any of the hardened concrete properties tested,” Wen, McLean and Willoughby conclude. “In addition, all samples tested met WSDOT minimum strength requirements for use in concrete pavements.” The authors emphasize that these results were obtained using RCA obtained from

demolished pavements incorporating high-quality original materials.

Light-emitting concrete Concrete pavements can emit light, with important safety benefits, according to a provocative new TRB paper.5 The researchers developed a soy-based luminescent “glow in the dark” (GITD) sealant for use on concrete surfaces. The luminescent sealant is a mixture of soy methyl ester polystyrene (SME-PS) and strontium aluminate; a phosphorescent powder that slowly luminesces after being excited by light. The sealant that could be applied to the surface of concrete has important safety benefits, in addition to creating a more durable pavement, the authors say. “GITD concrete sealant could be used to seal concrete for increased service life, to supplement streetlights, and to increase the safety of the traveling public at night,” they say. “If successful, the GITD sealant could be used to improve safety in construction zones or possibly replace streetlights in certain applications.” As GITD powder derives its luminescent qualities from sunlight, it’s more efficient than streetlights, which send light in all directions and draw approximately 2.3 percent of global electricity consumption. Safety of roadways would be increased by using a glow in the dark sealant as drivers will be able to see the road, its edges, or critical features more clearly, the authors write. “Roads, pedestrian trails, construction barrier walls, bridge piers, provide just some of the other potential applications for a GITD sealant,” they say. “Using a luminescent concrete sealant, one achieves a reduc-

tion of energy consumption by reducing or replacing streetlights, placing light where it is needed, sealing the concrete for a more durable pavement, and increased safety for the public.”

With APUs you can turn the chassis engine off and still have all the tools you need to work without running afoul of the law. “Most of the systems today feature a Tier 4 compliant engine,” he says.

Multi-function auxiliary power units like Vanair’s Air N Arc I-300 can provide welding, electrical power and compressed air in a single device.

Lighter weight The bigger fleets are sensitive to weight issues, says Eric McNally, vice president of sales at Reading. Using aluminum for the service body can cut the weight almost in half, he says. That means a Ford F-250 can stay under 10,000 pounds gross vehicle weight rating and avoid all the DOT licensing and complications that go with trucks heavier than that. Maintainer is also offering alu-

minum service body components. “With higher fuel costs there has been a need to provide a lightweight service truck for increased payload while reducing fuel costs,” says Wibben. Aluminum’s other big advantage is that it is corrosion resistant, he says.

Rightsizing trucks As business levels have picked up there has been a trend toward larger trucks, says Cook. Some of this is driven by the availability of funds for capital expenditures, while in other cases payload or crane capacity is the driver.

After the economy tanked in 2008 many contractors and fleet managers started paying close attention to the acquisition costs and applications for the truck. Too small a truck hurt productivity, while too large a truck created a longer payback period. Both mistakes can hurt ROI. A lot of companies try to do more with less, Heffron says, but that can get expensive if you load the truck up with auxiliary equipment.

you to use a driver without a commercial driver’s license (CDL), he says. Lifecycle costs factor into many contractors’ decisions, says Heffron. “They want a product that’s going to last for their planned usage and environment and still have value when it’s time to replace it.” And spec’ing a truck that a mechanic will enjoy spending his days in is also increasingly important, he says. This helps companies attract and retain qualified people.

Improved crane systems Customers are asking for a stronger fleet management approach to crane control systems and diagnostics, says Davison. This requires more advanced diagnostic and operator feedback, he says. Operators want to know more about what their lifting is doing and how the equipment is performing, he says. Longer reach cranes are also becoming a staple of the customer’s

needs, says Heffron, as well as cranes that operate with wireless controls.

Since many equipment manufacturers size their DEF tanks to be refilled every time you refill with diesel fuel, DEF storage is becoming increasingly prevalent on fuel trucks.

On mechanics trucks, DEF storage seems to be rare, but on the larger lube and fuel/lube trucks, more contractors are requesting it. “DEF has become a common product to carry on our lube trucks now that much of the equipment being serviced is equipped with those systems,” says Wibben.
