Caterpillar has introduced the Cat 253 compact track loader, placing the new machine between the existing 249D3 and 255 models in its 8,000- to 10,000-pound class. The company describes the 253 as a versatile solution for grading and material handling, with a rated operating capacity of 2,006 pounds (910 kilograms) and an operating weight of 9,343 pounds (4,238 kilograms) — figures that Cat says support easier transport between job sites.
Built on the foundation of the Cat 259D3, the 253 adopts a next-generation one-piece undercarriage. Its four fully independent axles mount directly to the frame, a layout Cat says supports traction and stability when handling heavy loads while enhancing grading capability. The loader runs on new 15-inch (380-millimetre) general-duty C-Pattern tracks designed to increase ground engagement and deliver grip in mud and other soft underfoot conditions. Cat describes the redesigned one-piece track roller frame as similar to the unit used on the 255, and notes that the 255 and 253 track types are interchangeable.
Cab options and hydraulics
Buyers can choose between a canopy and a sealed, pressurised cab. Hydraulic output differs by configuration: canopy models come with standard-flow hydraulics rated at 20 gpm at 3,336 psi (76 lpm at 23,000 kPa), while cab models are equipped with high-flow hydraulics rated at 30 gpm at 3,336 psi (112 lpm at 23,000 kPa).
Operator comfort and control
Cat equips the 253 with a standard high-back, heated air-ride seat and adjustable joystick pods. Operators can switch joystick command patterns between ISO and H layouts, and a full-colour 5-inch (127-millimetre) LCD screen with soft-touch buttons provides operating control. A two-speed transmission enables higher travel speeds, and aftermarket customisation is available through purpose-built kits.
Engine and serviceability
The electronically controlled Cat 3.3B engine is stated to deliver high horsepower and torque while meeting U.S. EPA Tier 4 Final/Stage V emissions standards. A tilt-up, one-piece cab design provides quick access to under-cab components, and Cat says ground-level access to daily service and routine maintenance points helps improve productivity.
Technology features
- Standard dual self-levelling automatically keeps attachments and material level when raising and lowering, for better stability and material retention.
- Return to dig/work tool positioner automates repetitive tasks to increase operating efficiency.
- Creep speed technology helps prevent overspeeding to achieve a smooth, precise finish in applications such as cold planing or fine grading.
Zach Waite, commercial director for Caterpillar Industry Solutions, said each model in the 8,000- to 10,000-pound compact track loader class features a unique undercarriage design engineered for a range of applications. He said combining the one-piece next-generation undercarriage with independent rigid, frame-mounted axles gives customers a system that helps deliver a stable platform when lifting and grading. Waite added that the 253 fits well between the 249D3 and 255, and that the C-Pattern track design is intended to give customers a productive all-around machine able to work on gravel, dirt, hard surfaces, turf, snow and unfinished terrain.
