ASV Holdings Inc., an industry-leading manufacturer of high-performance compact track loaders and skid steers, recently announced the largest and most powerful compact track loader in the industry: the large-frame, radial-lift Posi-Track RT-120. The rugged RT-120 helps operators easily handle tough excavation, mulching and other challenging applications within the aggregates, construction, landscaping, agriculture, forestry and snow removal industries. The RT-120, like all ASV machines, includes superior serviceability, highly efficient hydraulics and innovative, high-capacity cooling systems. These features allow operators to handle the largest attachments for longer without bogging down or overheating. ASV’s patented Posi-Track undercarriage provides versatility on all surfaces thanks to the industry’s highest ground clearance, lowest ground pressure, best traction and longest track life.
“The RT-120 is quite simply the largest, most powerful and highest performing compact track loader ever built. We designed the machine for the toughest jobs so our customers achieve maximum productivity and profitability,” said Jim DiBiagio, ASV chief operating officer. “The unit is part of our new lineup of compact track loaders revolutionizing the market with high-quality components, convenient serviceability and overall efficiency, power and performance. We use our 25 years of experience designing compact track loaders to deliver our customers a machine with a promise of maximum performance — no compromises!”
ASV builds all its machines from the ground up, starting with the undercarriage. The RT-120 features the company’s patented Posi-Track rubber-track suspension. The dual-level suspension — well known for its smooth ride — includes both suspended wheels and axles, allowing it to achieve faster speeds over all types of terrain. The fully-flexible track and suspended wheels conform to the ground, assuring maximum traction in the roughest conditions. In addition, the multiple wheel contact points and three guide lugs — compared to many machines with only one or two guide lugs — maximize performance on steep slopes. The RT-120 comes standard with 18-inch-wide tracks, resulting in a ground pressure of only 4.4 psi. Buyers can also choose optional 20-inch tracks. The features, combined with the RT-120’s 15 inches of ground clearance, allow the unit to work in more places, on more days and more comfortably than competitive machines.
Over the past 10 years, ASV completely transformed its undercarriage from a closed design — similar to those used on competitive steel-embedded undercarriages — to an open-rail and drive-sprocket design. The result is increased sprocket and bogie life and an undercarriage that’s easier and faster to clean. All rollers include mechanical face seals that don’t require maintenance for the life of the machine. The tracks contain embedded co-polymer cords for extra strength and are produced using a single-cure process, eliminating cure-point weaknesses in the track that can lead to premature breakage. The result is a 1,500- to 2,000-hour track life — 30 percent more than steel-embedded track units. ASV backs that up with an industry-leading two-year, 1,500-hour track warranty.
A Cummins 3.8-liter, turbocharged diesel engine powers the RT-120. The 120-horsepower engine produces 360 foot-pounds of torque — about 8 percent more than the machine’s 111-horsepower predecessor, the RT-110. The torque is transferred to the ground through direct-drive hydraulic motors. There is no need for servicing because the RT-120 does not use planetary drives, and highly efficient motors transfer maximum power to the patented internal-drive rollers. Internal rollers prevent friction loss in the undercarriage, allowing all power to be transferred to the track regardless of drive speed. The RT-120 achieves Tier 4 Final compliance using a diesel oxidation catalyst that, unlike DPF systems, requires no additional maintenance or replacement of filters.
ASV designed the machine with serviceability in mind, giving operators easy access to the reliable Cummins engine through a three-panel hood and tilting cooler arrangement. The design, paired with sight gauges for both hydraulic oil and coolant, simplify routine inspections of filters, oil and normal service items. The rearward tilting cab provides easy accessibility when further service is required.
ASV built the RT-120’s auxiliary hydraulic system to be highly efficient, including 45 gpm high flow and 4,060 psi. Because the machine includes larger line sizes, hydraulic coolers and direct-drive pumps — rather than belt-driven pumps — more flow and pressure transfers directly to the attachment. This allows operators to maximize horsepower efficiency while running demanding attachments, such as brush cutters and mulching heads. Many competitive machines lose as much as 30 percent of the horsepower shown on their spec sheets as a result of belt-driven pumps and restrictions in their hydraulic systems. Conversely, the RT-120 achieves 16 percent more actual hydraulic horsepower than the PT-110 compact track loader it replaces.
The RT-120 achieves superior performance over competitive machines. The unit features a rated operating capacity of 3,535 pounds and a tipping load of 10,100 pounds. It is 71 inches wide and has a 125-inch lift height. Standard joystick controls make operation easy and intuitive. The machine’s cab is pressurized for a clean operator environment. Buyers can also choose an optional all-weather cab that includes heat and air-conditioning. The RT-120 works with all standard attachments, such as backhoes, buckets, snow blades, brush cutters and pallet forks.
ASV also offers a road profiling as well as a heavy-duty forestry option of the RT-120. The RT-120 Forestry includes metal guarding around areas such as lights, the AC condenser and the rear screen. The unit also features superior rollover and falling object protection as well as reinforced windows for impact resistance. The machine uses a hydraulically driven, auto-reversing cooling fan to blow debris out of the engine compartment screens.
“We strive to provide equipment our customers can use for the toughest jobs, no matter the conditions,” said Bill Wake, ASV director of product development. “The RT-120 delivers a high return on investment by allowing workers in demanding industries such as forestry and excavation to work longer and more productively in a wide variety of applications. We’re always committed to maximum performance with no compromises and the powerful RT-120 doesn’t disappoint.”
