Caterpillar has introduced the Cat 253 compact track loader, a machine designed for grading and material handling that the company positions between its existing 249D3 and 255 models. The 253 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 loader builds on the Cat 259D3 foundation and adopts a next-generation one-piece undercarriage with rigid, frame-mounted axles. According to Caterpillar, four fully independent axles mount directly to the frame to support grading capability, while the redesigned one-piece track roller frame, similar to the arrangement used on the 255, is intended to add stability and operator confidence when lifting and grading.
Undercarriage and tracks
The 253 runs on new 15-inch (380-millimeter) general-duty C-Pattern tracks. Caterpillar says the design increases ground engagement and delivers strong grip in mud and other soft underfoot conditions. Zach Waite, commercial director for Caterpillar Industry Solutions, said 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.
Cab, controls and hydraulics
Customers can choose between canopy and sealed, pressurized cab designs. 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 fitted with high-flow hydraulics at 30 gpm at 3,336 psi (112 lpm at 23,000 kPa).
Both configurations include a standard high-back, heated air-ride seat with adjustable joystick pods. Operators can switch joystick command patterns between ISO and H patterns to suit preference. A full-colour 5-inch (127-millimeter) LCD screen with soft-touch buttons provides operating control, and a two-speed transmission supports higher travel speeds.
Engine and serviceability
The electronically controlled Cat 3.3B engine delivers high horsepower and torque while meeting U.S. EPA Tier 4 Final and Stage V emissions standards. A tilt-up, one-piece cab design provides quick access to under-cab components, and daily service and routine maintenance points are reachable from ground level to help improve productivity. Purpose-built kits allow aftermarket customization.
Technology features
Cat technology is included to advance efficiency and safety on the job site, and the company says the 253's connected-worksite capabilities help streamline equipment maintenance. Standard dual self-levelling automatically keeps attachments and material level when raising and lowering for better stability and material retention. A return-to-dig/work tool positioner automates repetitive tasks to increase operating efficiency, while creep speed technology helps prevent overspeeding to achieve a smooth, precise finish in applications such as cold planing or fine grading.
Waite said each model in the 8,000- to 10,000-pound compact track loader class features a unique undercarriage design engineered to optimize performance across a wide range of applications, and that adding the 253 to the line gives customers another solution for meeting their toughest challenges.
