Compact track loaders offer versatility and a return on your investment

Beyond plenty of tractive effort and 66 horsepower, Bobcat’s K-Series T180 can also be operated via remote control.

Boasting many of the benefits and capabilities of its cousin, the best-selling skid-steer loader (SSL), the compact track loader (CTL) has altered the landscape of the heavy equipment marketplace in a big way. That success has sparked much debate over whether a CTL or an SSL is the better investment. In the end, the choice comes down to matching the equipment to the application. CTLs are more versatile, able to work on soft ground and in wet conditions, but are also more expensive to purchase and operate than SSLs, which perform well on asphalt and in tighter spaces.

But what kind of changes have CTLs undergone themselves in recent years? With rising demand, the companies behind these versatile machines have not been content to let innovation stagnate. With new features that make for a more comfortable ride and a less disrupted jobsite, work is constantly being done to reinvent the wheel – or in this case, the track.

 

Explosive growth

Jamie Wright, Terex Construction Americas product manager, explains that CTLs saw a slow start in the U.S. market until about 10 years ago. “The CTL market shot up due to the demand that jobs get done faster and more efficiently,” Wright says. Caterpillar senior marketing engineer Kevin Coleman calls the last decade of growth in the CTL market “an explosion,” as more customers have grown to favor the traction, flotation, machine stability and minimal ground disturbance CTLs offer. “Compact track loaders are essential machines for many applications,” Coleman says.

“The CTL market shot up due to the demand that jobs get done faster and more efficiently”

Bobcat loader product specialist Mike Fitzgerald agrees. “Compact track loaders are more powerful and productive than ever before, making them more than just an auxiliary piece of equipment,” he says. “Because of the increased flotation provided with their tracks, these loaders can work in softer ground conditions while carrying heavier loads, plus their versatility has grown exponentially with attachments.” Bobcat marketing manager Greg Rostberg adds: “Growth has been phenomenal in the last decade and many more manufacturers are producing CTLs because the demand is there.”

Wright, however, disagrees. He says Terex has seen a shift in favor from the CTL back toward the skid steer loader since the 2008 economic downturn. Wright estimates that CTLs make up between 20 and 25 percent of the market while SSLs hold between 75 and 80 percent. “The compact track loader trend started … as a result of contractors wanting to get jobs done faster, no matter what the acquisition costs or operational costs of the unit,” he explains. “With the economic downturn, contractors were more selective and looking for ways to manage their equipment inventories more efficiently. As part of this, they are adding skid steer loaders back into their fleets since they are able to accomplish many of the same tasks at a lower operating expense.”

 

Cost

Despite their versatility, the major drawback to CTLs has been their high initial investment and operating costs, compared to skid steers. However, each manufacturer that spoke with Equipment World say significant strides have been taken to address this issue. Coleman says, for example, the work Cat has done to maximize track life has contributed to making CTLs more affordable. “Track technology has advanced. Now track composition and construction better align with the rigorous load and weight requirements of a compact track loader,” he says. “As a result, the life of the tracks is far better than what would have been achieved just a few years ago.”

“With proper operation of the loader, rubber tracks should last about twice as long as tires,” Fitzgerald says.

 

Bobcat’s Fitzgerald says a CTL’s operating cost can be drastically reduced by evaluating the types of applications your CTL performs best in, keeping them busy in those applications, calculating the increased productivity attachments may add and, of course, performing regular maintenance. “Rubber tracks cost $3,000 to $4,500 per set and last 1,200 to 1,600 hours. With proper operation of the loader, rubber tracks should last about twice as long as tires,” Fitzgerald says.

Though CTLs are more expensive to purchase and operate, they can also be more cost effective than other loaders because they are able to operate in more jobsite environments. To prevent premature track failure, which can easily negate any added benefits the CTL offers, Wright recommends operators avoid the temptation of running CTLs in the same way they do skid steers. That means no counter-rotating and spinning the tracks, which sends a lot of material into the undercarriage.

“Compact track loaders have enough traction; the tracks do not need to spin to fill the bucket,” he says. “If the tracks are spinning, and the machine is staying still, your track life will be greatly reduced. When you counter-rotate with a compact track loader, especially in loose underfoot conditions, a lot of material is ingested into the undercarriage. Three-point turns, rather than spinning or counter-rotating, will save on undercarriage wear.”

If all goes well, Wright says a CTL can pay for itself in as little as 18 months. Fitzgerald adds that Bobcat has seen its CTLs add days – and in some cases, months – of income to its customers’ seasons. When choosing a compact track loader, Wright recommends customers choose one that will be adequate for 85 to 90 percent of their needs. “Don’t sacrifice just to save a dollar,” he says. “Always buy quality; a loader and attachment needs to durable and reliable because downtime is expensive. Be sure to select equipment that makes the most sense for the applications it’ll be used in.”

Terex’s PT-60 is the company’s largest compact track loader in this category with an operating load of 1,900 pounds.

“You should also consider the reliability of the machine/attachment and how well you know and understand its parts,” Fitzgerald says. “Are you comfortable with the technology? If you can handle the small maintenance issues yourself, you can help reduce overall cost and downtime.”

 

A smoother ride

When talking about how CTLs have evolved in the past decade, the conversation always comes back around to the tracks and undercarriage. “One of the significant advantages of tracked loaders is low ground pressure,” Coleman says. “The greater the amount of track on the ground, the greater the traction and the lower the ground pressure.” Recently, some manufacturers say they have been focusing attention on the suspension systems of these machines to lower ground pressure.

“Systems with suspended axles help distribute weight more evenly when a machine is loaded and also ensure tracks maintain maximum ground contact,” Coleman explains. Caterpillar brought the torsion axle suspension system from its multi-terrain loader platform to CTLs such as the 259B3, providing the machine with an independent, fully-suspended steel-embedded rubber track undercarriage. “The undercarriage suspension on both the CTL and the MTL undercarriages distributes the machine load to greatly reduce shock and vibration throughout the machine so that the operator is more comfortable. This decreases owning and operating costs by allowing the suspension to absorb the shock loading that would normally be driven into your tracks.”

John Deere’s 319D is powered by a Tier 4-certified engine that provides the machine with 63 horsepower and a 2,900-pound operating load.

Coleman says in the under 3,000-pound operating load size class customers are “seeking substantial performance increases” in both the engine and hydraulics “to allow these small-frame machines to perform as larger machines in confined spaces. Essentially customers want a power dense machine.” He says Cat’s 257B3 and 259B3 models were updated in 2010 to meet that demand.

And while some companies use the same frames for both their SSLs and CTLs, Terex says it builds its machines as CTLs from the ground up with its Posi-Track technology. Wright says all Terex undercarriages are built with a torsion axle suspension that also creates a comfortable ride while reducing vibration and shock to the machine. In order to provide more even weight distribution, Terex designs its CTLs with a greater number of bogie wheels, lowering impact when traveling over rocky or rough terrain.

And though most of the industry has opted for a steel-embedded track, Terex uses its own all-rubber track, which Wright says is lighter in weight than steel-embed tracks and extends the life of the undercarriage components. “Unlike with steel-imbedded tracks, rust and corrosion are not a problem,” he says.

Fitzgerald says one of Bobcat’s biggest design changes has been its roller suspension system for CTLs, which uses an all-steel design with steel-embedded tracks. “A comfortable ride is achieved by the durable steel leaf springs, which greatly reduce the feedback from the ground,” he says. “The smooth ride coupled with easier turning, less vibration and noise, works to keep operators more comfortable.” He added that Bobcat’s roller suspension system features an enclosed steel undercarriage with few moving parts, to minimize maintenance costs. Forged steel rollers and idlers are permanently sealed and lubricated, requiring no routine maintenance. Fitzgerald noted that track tensioning is also easy, requiring no special tools – just a normal grease gun.

In addition to the roller suspension system, Bobcat has worked to keep up with the more sophisticated electronics in machines. The company’s Deluxe Instrumentation Panel option offers contractors the ability to monitor various attachments, machine management, security and system protection, as well as troubleshoot issues.

Takeuchi has a different take on the undercarriage entirely, says David Steger, product manager. Rather than a suspension system, Takeuchi CTLs, including the TL230 Series 2, ride atop a fully-welded and integrated track frame that incorporates a unitary design. “We use forged-steel rollers riding directly on a pad of metal imbedded into the track…we feel that gives us some additional durability along with wider operating ability,” Steger says.

Steger adds that Takeuchi’s also working to increase an operators’ ability to tailor a CTL’s power output for the work being done. “Our newer machines have an Eco Mode feature that was inspired by the auto-idle found on excavators,” he says. “It reduces the maximum rotations per minute that an operator can achieve while maintaining torque and horsepower. If the engine load is below 35 percent, the engine rpm will actually decrease even more. And when the load exceeds that, the engine speeds go back up.” Steger estimates Eco Mode could save a contractor up to 50 percent on their fuel bill.

 

Looking forward

What does the future look like for these machines? Is it possible for CTLs to overtake the skid steer loader in popularity and market share?

“The track loader market has really taken off in the last decade, with the largest market in North America. I believe that the benefits a track loader model provides will become more recognized in other regions and increase their track adoption rate,” Coleman says. “However, we don’t see the compact loader market in terms of popularity of tracks versus wheels.”

Bobcat’s Rostberg says while the CTL market share will continue to grow, there will always be a demand for wheeled machines. “This is especially true in applications involving concrete or asphalt, or if an operator needs to travel a significant distance on a jobsite,” he says. “Demolition applications are also best approached with a wheeled machine with solid-filled tires. In those cases, skid-steer loaders will always perform better.”

Wright says Terex has a positive outlook on CTL sales due to their versatility in numerous applications. Rental is in fact one of the top markets for CTLs,” he says. And while he isn’t sure if they will ever surpass SSLs in popularity, Wright doesn’t rule out the possibility of their matching SSLs in sales. “As the construction industry continues to recover, compact track loaders could again become as popular as skid steer loaders because their productivity is incredible.”
