Caterpillar has introduced the Cat 253 compact track loader, a machine positioned for grading and material handling that slots between the existing Cat 249D3 and 255 models. The new unit 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 is built on the foundation of the Cat 259D3 and adopts a next-generation one-piece undercarriage. Its rigid, frame-mounted axles are designed to support traction and stability when the machine handles heavy loads, while four fully independent axles mount directly to the frame to enhance grading capability.
Undercarriage and track design
New 15-inch (380-mm) general-duty C-Pattern tracks are intended to increase ground engagement and deliver grip in mud and other soft underfoot conditions. Caterpillar describes the redesigned one-piece track roller frame, similar to the one used on the 255, as contributing to stability and operator confidence.
Zach Waite, commercial director for Caterpillar Industry Solutions, said each model in the 8,000- to 10,000-pound compact track loader class has a unique undercarriage engineered for a range of applications. He said the 253 gives customers another option for demanding work, adding that pairing the next-generation one-piece undercarriage with independent, rigid, frame-mounted axles provides a stable platform when lifting and grading.
Waite said the 253 fits well between the Cat 249D3 and 255, and that the C-Pattern track design produces a productive all-around machine able to work on gravel, dirt, hard surfaces, turf, snow and unfinished terrain. The 255 and 253 track types are interchangeable, he added, giving customers more options.
Hydraulics, cab and operator features
Two hydraulic configurations are offered. Canopy models come standard with standard-flow hydraulics rated at 20 gpm and 3,336 psi (76 lpm at 23,000 kPa), while cab models come standard with high-flow hydraulics rated at 30 gpm and 3,336 psi (112 lpm at 23,000 kPa).
- Canopy and sealed, pressurized cab designs are available to match operator preference.
- A high-back, heated air-ride seat and adjustable joystick pods are standard.
- Joystick command patterns can be switched between ISO and H patterns.
- An electronically controlled Cat 3.3B engine delivers high horsepower and torque and meets 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 daily service and routine maintenance points are reachable from ground level.
- A two-speed transmission enables higher travel speeds.
- A full-colour, 5-inch (127-mm) LCD screen with soft-touch buttons provides operating control.
- Purpose-built kits allow aftermarket customization.
Technology and control
Caterpillar highlights technology intended to advance efficiency and safety on the job site, with connected worksites used to help streamline equipment maintenance. Standard dual self-levelling 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 to raise operating efficiency, and creep speed technology helps prevent overspeeding to achieve a smooth, precise finish in applications such as cold planing or fine grading.
