Caterpillar has introduced the Cat 253 compact track loader, a new model aimed at grading and material handling that the company positions between the Cat 249D3 and 255 in its lineup. The machine carries a 2,006-pound (910-kilogram) rated operating capacity and an operating weight of 9,343 pounds (4,238 kilograms), a combination the company says supports easier transport between job sites.
The 253 builds on the Cat 259D3 foundation and adopts a next-generation one-piece undercarriage with rigid frame-mounted axles. Its four fully independent axles mount directly to the frame, a design Caterpillar says enhances grading capability. New 15-inch (380-mm) general-duty C-Pattern tracks are intended to increase ground engagement and deliver strong grip in mud and other soft underfoot conditions.
Stability and configuration options
The redesigned one-piece track roller frame is similar to that used on the 255, which the company links to stability and operator confidence. Buyers can choose between canopy and sealed, pressurized cab designs. Hydraulic output differs by configuration: canopy models come with standard-flow 20 gpm at 3,336 psi (76 lpm at 23,000 kPa) hydraulics, while cab models are equipped with high-flow 30 gpm at 3,336 psi (112 lpm at 23,000 kPa) hydraulics.
For the operator, a standard high-back, heated air-ride seat with adjustable joystick pods is intended to provide all-day comfort. Joystick command patterns can be switched between ISO and H patterns to suit preference. The electronically controlled Cat 3.3B engine is described as delivering high horsepower and torque while meeting U.S. EPA Tier 4 Final/Stage V emissions standards. A two-speed transmission enables higher travel speeds.
Service access, controls and technology
Service and maintenance are addressed through a tilt-up, one-piece cab design that provides quick access to under-cab components, along with ground-level access to daily service and routine maintenance points. A full-colour 5-inch (127-mm) LCD screen with soft-touch buttons provides operating control, and purpose-built kits support aftermarket customization.
Caterpillar also highlights connected features on the machine. Standard dual self-levelling automatically keeps attachments and material level when raising and lowering, which the company says improves stability and material retention. A return to dig/work tool positioner automates repetitive tasks, and creep speed technology helps prevent overspeeding for a smooth, precise finish in applications such as cold planing or fine grading.
Positioning and applications
Zach Waite, commercial director at Caterpillar Industry Solutions, said each model in the 8,000- to 10,000-lb compact track loader class features a unique undercarriage design engineered to optimize performance across a wide range of applications. He said the addition of the 253 gives customers another solution for their toughest challenges, and that combining the one-piece next-generation undercarriage with independent rigid, frame-mounted axles helps deliver a stable platform when lifting and grading.
According to Waite, the 253 fits well between the Cat 249D3 and 255 models, and the C-Pattern track design gives customers a productive all-around machine that can perform on gravel, dirt, hard surfaces, turf, snow and unfinished terrain. He added that the 255 and 253 track types are interchangeable, giving customers more options.
