Customer-Inspired Technology.

“So, what is better about Tier 4 Final engines?” That’s a likely question from operators looking to purchase new equipment from the dealer. The obvious answer is that they meet near-zero emissions regulations to improve air quality. Perhaps less obvious is that Cummins Tier 4 engines also bring improved engine sociability to the job site, with cleaner, smoother and quieter operation than their Tier 3 predecessors. Field-test users made a point of telling us that Tier 4 made a real difference to their working environment.

But an equally valid message to deliver to your customers is that Cummins achieves near-zero emissions with no compromise to engine reliability. From the start of our Tier 4 work, we put in-service dependability at the top of our priority list. No other engine company has a stronger reputation in that respect than Cummins, so we had to set our sights higher than others in the engine industry to meet the expectations of all our customers, from OEMs to their dealers and the equipment users. This approach means our Tier 4 technology is inspired – and driven – by our customers.

So, I am delighted to report that our low-emissions technology is doing what we said we would do. Our tracking of Cummins Tier 4 engine population since 2011 clearly indicates that equipment operators are seeing the same level of uptime availability as they experience with our mature Tier 3 engine population.

You can find more about that – and much else to support your Tier 4 business – in this edition of CTB. If you need more details on any of the topics, please contact your local Cummins distributor, or feel free to e-mail


Tier 4: In-Service Report

The advantage of Cummins Tier 4 low-emissions engines comes with no compromise to reliability or fuel efficiency. That has been confirmed by in-service reports based on a large 6-cylinder engine population in operation since the introduction of exhaust aftertreatment from 2011 through 2015. Analyses of warranty data and service events clearly indicate that Cummins low-emissions engines are delivering uptime availability at least equal to that of previous Tier 3 engines with an established reputation for reliability.

The Tier 4 engines are also capable of achieving between 8 percent to 10 percent better fuel efficiency compared with Tier 3, depending on equipment type and duty cycle. With no impact on service costs, and with lower fuel consumption, it adds up to a great message for your customers.

QSF On Track With ASV®


Midsized tracked loaders are increasingly popular because they offer the ability to perform a variety of tasks while working on soft or rough ground, and few come with as strong as reputation as ASV’s RT range, with its renowned Posi-Track® system.

Working closely with Cummins NPower, ASV has recently installed the QSF2.8 and QSF3.8 in two RT models – the popular RT-75, rated at 74 hp, and the soon-to-be-released RT-120, taking output up to a new high of 120 hp.

“We are really excited to see the QSF engine featured in the RT lineup,” said John Laka, Off-Highway Business Leader – "Operators will notice the enhanced performance those engines offer in the tracked loaders, plus they work more smoothly and quietly when under load compared with many other engines,” he said.

In 2014, ASV LLC was formed through a joint venture by Manitex® Inc. and Terex,® wherein Manitex owns 51 percent of ASV. In April 2015, ASV LLC began marketing its own line of compact track loaders under the ASV brand. The tradition of innovation and expertise in rubber-track undercarriage design that started in the early 1980s continues today.

ASV will continue to manufacture the
Posi-Track range for the Terex Gen2 range, built at ASV Grand Rapids, Minn.

Manitowoc® Heavy-Duty Duo

Manitowoc Cummins NPower Logos

Manitowoc has started deliveries of its two new huge crawler cranes – the 330-ton MLC300, powered by the QSG12, and the 717-ton MLC650, powered by the QSX15. Introduced for
Tier 4 Final at CONEXPO last year, these hotly anticipated cranes are already proving their worth on the work site.

“Our heavy-duty engine duo provides an ideal power match for each of these highly impressive cranes, and operators know that no other engines in the 450 hp-to-600 hp class come with more inherent durability than Cummins,” said John Laka, Off-Highway Business Leader. “These cranes are intended to be transported anywhere in the world, and of course Cummins will be there, ready to provide whatever engine support is needed,” he said.

VPC Models

The two MLC cranes feature the Variable-Position Counterweight (VPC) configuration, a unique floating counterweight design that decreases the amount of space taken up on the job site and reduces ground-bearing pressure.

With optional VPC-MAX, as forward movement is increased or decreased; the counterweight position is changed to offset changes in movement.

The heritage of Manitowoc Cranes dates back to 1925, when the company built its facility in Manitowoc, Wis. Today, as a global leader in crawler cranes, the company’s range extends from 80 U.S. ton to 2,535 U.S. ton capacity, relying on the local support of Cummins NPower machine integration expertise for Tier 4 Final engines such as the QSL9, QSG12 and QSX15. Equally important to Manitowoc is the Cummins global support network, which provides the field expertise to keep its cranes up and running – and keeps customers loyal to both famous brands.


Manitowoc® Wind Farm Lift

30 m (98 ft.) fixed jib attachment on main boom
157 m (515 ft.) luffing jib maximum combination
107 m (351 ft.) wind attachment maximum length

Bigge Crane and Rigging is the first company to put the Manitowoc MLC650 to use, employing the innovative crane to erect a large wind farm in Minnesota.

The MLC650 is rented to Broomfield, CO based Renewable Energy Systems (RES), which is using the crane to erect wind turbines at the Pleasant Valley Wind Farm near Austin, Minn. The company is using the crane to erect 18 towers on what will be a 200-megawatt-generating project when it’s completed in late 2015.

Weston Settlemier, president and CEO of Bigge, said the MLC650 offered several advantages over other large crawler cranes for the wind farm project. “Moving forward, we expect the wind turbine market to demand the MLC650 over the current offering of crawler cranes because the Variable-Position Counterweight saves time and money. The crane’s technology allows for the VPC-balanced technology reduces the point loading of crawlers, and reduces ground preparation required by the wind turbine erection contractor.”

On the site, the MLC650 is configured with 341 feet. of main boom, 24.9 feet of extended upper boom and only 326 U.S. tons of counterweight. The crane is lifting prefabricated wind tower sections and turbines in loads weighing up to 118 U.S. tons. It is also erecting blades that weigh 12.5 U.S. tons each to heights up to 295 feet. The VPC system dynamically positions the MLC650’s counterweight to suit each lift. The counterweight moves along the rotating bed, and is automatically positioned based on changes in operating radius.

The company will also soon deploy its second MLC650 to job sites, where it’s expected to be used on power plant projects.

The first Manitowoc MLC300 to go into action belongs to Milwaukee-based Dawes Rigging & Crane rental, an ALL Erection group company – one of 10 MLC300s that ALL has on order. The crane was leased to Lunda Construction of Black River Falls, Wis., for a highway project at the Zoo Interchange, just west of Milwaukee. The first lifts involved setting large tub girders for a highway ramp weighing over 68 U.S. tons and measuring up to 66 feet.

The crane was rigged with 157 feet of main boom and 190 U.S. tons of counterweight. Joe Ruddell, sales manager at Dawes Milwaukee, said, “One big challenge is the limited space we have to situate the crane in, along with having to move the crane from one location to another in a limited amount of time over uneven ground conditions. The MLC300 offers a smaller footprint than other crawler cranes, and its Variable-Position Counterweight system is perfect for this job. The MLC300 has afforded us greater lifting capacity and more stability, and it needs less ground prep time and around 50 percent less matting, which can mean thousands of dollars in savings a month.” The interchange job is due to continue until 2018.

Introducing The Expert Diagnostics System (EDS)

Red Shirt

Getting To The Root Cause – Fast.

Imagine that an operator has a recurring issue with a QSB6.7-powered excavator working on a road construction site in your area. How valuable would it be to have the troubleshooting information from all other similar pieces of equipment that are operating globally? Now Cummins has the capability to do just that, and it’s called the Cummins Expert Diagnostic System (EDS).

EDS is an intuitive Web-based platform that works through Cummins INSITE tool to give every technician access to that knowledge base, both in the service shop and out in the field, all across the globe. All repair information is compiled into a database, creating smarter troubleshooting trees that can reduce the number of diagnostic steps by up to 50 percent.

EDS also provides a complete repair history of all diagnostic service events that have been performed on a particular engine. Cummins EDS does more than just provide improved troubleshooting trees for your technicians. It’s a tool that also improves every aspect of the repair process, from productivity and accuracy to billing and reimbursement. And it’s going to get even better, because every day, as more service events are logged into the database, EDS will continue to “learn” and provide even better advice on even the most complex troubleshooting challenges.

It’s the smartest, fastest engine diagnostic system in the industry, and it’s available to all of our dealers.

  • Increases equipment uptime
  • Provides faster, more accurate diagnostics
  • Reduces labor time for repairs by minimizing unnecessary steps
  • Makes every technician an instant Cummins engine expert

“EDS has been a helpful tool to our service technicians. It helps us to get to the root cause of the failure faster than using the troubleshooting tree, and even works well on remote sites, helping to cut customer downtime.”

Cold-Weather Aids

As temperatures drop, operators need to ensure that they are taking the right measures to make sure their engines will start when they need them to. It is important that the correct winter diesel fuel is used that doesn’t wax at the temperature the engine is operating at. The coolant and lube oil specification also need to be appropriate for the engine, and capable of operating down to at least -40° F (-40° C). Talk to your Cummins distributor about advice on the correct diesel and fluids for engines to start readily in the cold temperature conditions the equipment is working in.

Most Cummins Tier 4 engines in your equipment will have a standard intake manifold grid heater, but may also come with factory-fitted cold-start-aid options specified by the OEM. They can include an oil-pan (lube) heater, coolant (block) heater, fuel filter heater and crankcase breather heater, which typically enable a minimum ambient-temperature cold start down to -40°F (-40°C). Ether injection is approved for use only with the QSX15, which does not have a grid heater option.

Operators may also benefit from using a range of superior Fleetguard® cold-weather aids available as aftermarket products, including:

  • Battery warmer blankets
  • Coolant heaters
  • Diesel fuel warmers
  • Lube-oil heaters

Cummins Filtration also offer accessories such as wiring harnesses, power receptacles, extension cords and more for cold-weather aids. For information on cold-weather aids or other Fleetguard products, visit

Battery Warmer Blankets

Batteries have only 75 percent of their cranking power available at 10°F (-12°C). By -5°F (-21°C), only about 60 percent is available. By -40°F (-40°C), cranking power is virtually nonexistent. Battery warmers plug into the nearest outlet to retain cranking power for ready starts. Fleetguard® wraparound battery warmers feature:

  • Enough warmth to keep full battery power through the coldest nights
  • Fast and easy installation
  • Oil- and acid-resistant heavy vinyl cover
  • Thick fiberglass insulation that retains warmth even when the warmer is not plugged in

Blankets are CSA-approved, but are not recommended for nickel cadmium batteries.

Coolant Heaters

Cummins Filtration offers both immersion heaters and remote- mount coolant tank heaters. Their purpose is to keep coolant and cylinders warm so that cranking power is used to heat the fuel, not the cold metals surrounding it.

Because the combustion temperatures needed to ignite. No. 2 diesel fuel are 550°F (288°C) to 600°F (316°C), warmed coolant is vital to the starting process, even in temperatures as warm as 50°F (10°C). Coolant should be maintained at a minimum of 120°F (49°C) for a diesel engine to start readily.

Diesel Fuel Warmers

The clouding and waxing of diesel fuel is a problem during cold temperature conditions. In addition, No. 1 diesel is no longer readily available in all climates. Diesel fuel additives are helpful but not completely effective, and they are expensive. Fleetguard’s selection of diesel warming alternatives is representative of the best products on the market today. Make your selection based upon operating environment and other starting/warming aids in use on the vehicle.

Lube Oil Heaters

Lube oil pan heaters are needed to keep lubricant flowing freely so that full power is available immediately. Adaptable to all sumps, these heaters should be installed at a low point in the sump to allow heat to rise. Engine oil, transmission fluid and hydraulic fluid may be warmed with Fleetguard oil immersion heaters. Special attention should be paid to wattage requirements according to system capacity and temperature in the environment. The use of 10 to 20 watts per quart of oil is recommended. In moderate climates, a thermostat is recommended in order to avoid charring or coking if wattage exceeds 10 watts per quart.

The QSB6.7 has reached new heights of Tier 4 performance – literally – by working on the top of the Manhattan skyline to power the high-speed hoists for Timberland derrick cranes, used for dismantling tower cranes after a new skyscraper is topped out.

Sitting some 1,400 feet (427 meters) above New York City, the QSB6.7 engines provided the strength and smooth power delivery required for precision lifting on the tallest buildings in the Western Hemisphere – 1 World Trade Center and 432 Park Ave.

Most of the derrick cranes manufactured by Timberland Equipment of Ontario are used on high-rise towers, the most popular model for the work being the ASD 35/120 Stiffleg derrick, with hoists powered by the Tier 4 Cummins 6-cylinder QSB6.7 and 4-cylinder QSB4.5. The 35-ton-capacity derrick is fully portable, consisting of a reinforced mast, swinger boom, support legs, wire drum hoists, diesel power modules and controls – all in a lightweight, high-strength modular format so that assembly and load testing on the roof can be completed within five days.

432 Park Ave

The pencil-thin skyscraper is 88 floors above ground, and at 1,396 feet, has a slightly taller roof than 1 World Trade Center, which is at 1,362 feet excluding the spire, which brings its official height to 1,776 feet. After the building was topped out, the Potain® tower crane lifted the Timberland ASD 35/120 Stiffleg derrick, where the compact design fits well within the crowded space of a roof.

The derrick disassembled the tower crane boom in four pieces, then lowered them to the ground vertically. Next, the 14 tower sections were lifted out of the internal climbing collars holding them in place, and lowered to the ground. Almost all the lifts were accomplished at a 70-foot radius, allowing a 25-foot clearance to the front of the building. When the tower crane was removed, the derrick was used to make some final installations, including a window-washing rig and a huge chiller lifting into the 83rd floor.


QSB6.7 Takes Tier 4 To New Heights

The main hoisting work was undertaken by a GP500 hoist powerpack with a Tier 4 QSB6.7 rated 260 hp at 2300 rpm, with a second powerpack available with a Tier 4 QSB4.5 rated 160 hp. The GP500 hoist travels at a high speed of 85 feet per minute, which gave a 14,000-lb line pull, and nearly 50 feet per minute in low speed, with a 50,000-lb pull. The total capacity of the ASD35/120 derrick is 70,000 lb (35 tons).

Given the need for environmental considerations working in such a sensitive location, the Tier 4 engines provide clean, fuel-efficient power for the derrick. Engine dependability was critical, as any issue with the derrick could severely impact a very tight job completion schedule and soon run up a high cost.

Although preceded by a long process of logistical planning with the crane rigging contractors, the Timberland derrick was situated on the roof for just six weeks, including a week to build and test. The ASD35 derrick proved strong enough to work in winds of 30 mph at the top and 15 mph at the bottom on the building, with only five days lost due to clouds or fog preventing work.

With all lifting work complete, the derrick was demobilized and taken down using the elevator, being broken down into sections of about 8 feet, which allowed it to be
man-handled. The Tier 4 QSB6.7- and QSB4.5-powered derrick worked perfectly on the 432 Park Ave. project, and the contractor – Able Rigging – so impressed that it ordered a second ASD35 derrick for its supertall building crane fleet.

1 World Trade Center

As the new 1 World Trade Center neared completion in May 2013, Timberland supplied a 35-ton capacity ASD35 Stiffleg derrick with double-drum hoist using 1-inch (25-mm) wire rope to perform the required pickup and lowering of the tower crane used throughout its construction.

The dismantling project was completed smoothly and without incident by rigging contractor DCM Erectors. Powered by a Tier 4 QSB6.7 engine rated 260 hp, the derrick’s first job was to carefully lower the big tower crane’s 160-foot-long boom down to ground level, some 105 floors below the roof.


Red QSX15 Goes Deere® Green

With the 2015 release of Deere’s 9R Series tractors, Cummins iconic red engines went green to match the famous color of the supersized tractors. The 9R Series is intended for large-scale farmers who need to cover lots of acres under tough conditions with a new breed of cleaner, higher performance tractors meeting Tier 4 Final near zero emissions regulations, including tracked versions.

Of the nine 9R models Deere released in 2015, Cummins 15-liter powers the 9570RT (570 hp), the 9570R (570 hp) and the 9620R (620 hp). The QSX15 sets the standard for heavy-duty engines at Tier 4 Final, and this made for an ideal solution when Deere needed a higher rated power than the 572 hp achievable with the PowerTech PSS 13.5-liter. John Deere and Cummins have a long relationship with high-output engines, extending back to 1969, when a Cummins 14-liter NT855 powered a John Deere 4-wheel-drive tractor.

"The 9R installation restores a historic link with one of the earliest Deere 4-wheel-drive big tractors powered by Cummins over 40 years ago and we very proud to be continuing that power partnership now with the QSX15,” said Kevan Browne, Cummins Marketing Communications. “In fact, no other engine company has played such a prominent role in powering high-power, 4-wheel-drive tractors as Cummins since they were first introduced by Wagner in the late 1950s."

Antarctic Snow Cruiser

The giant Snow Cruiser made headline news as a unique diesel-electric expedition vehicle intended to drive to the South Pole, powered by 2x150-hp Cummins HBI-600 6-cylinder 11-liter, regarded as the most dependable diesel of its time. The drive system gave space for the crew, equipment, fuel and supplies for a self-sufficient 5,000 mile-trip, with aircraft attached. However, the 38-ton weight proved too great to allow traction in the deep snow and ice, and the vehicle was abandoned when World War II began. The vehicle had a bold but overly ambitious design, but did lay the foundation of diesel-electric drive on large mining haul trucks in the 1960s. In 1958, the Snow Cruiser was found buried deep in the snow, and was left in place for later use, but then disappeared without trace.
