CATERPILLAR 319D L CRAWLER EXCAVATOR

The Caterpillar 319D L Excavator is a versatile machine optimized for medium-scale earthmoving tasks, powered by a Cat C4.2 ACERT engine delivering 131 hp gross (125 hp net) with 256.3 cu in displacement. It features a robust hydraulic system with a maximum implement pump flow of 7.1 gpm and a relief valve pressure of 5076 psi, ensuring strong digging and lifting performance. The operating weight is approximately 43,872 lbs, supported by a durable track-type undercarriage with 27.6-inch shoes, a 7.3-foot track gauge, and a max travel speed of 3 mph. The machine attains a maximum drawbar pull of 46,468 lbs and ground pressure of 5.2 psi, balancing traction and ground impact effectively. Three boom and stick configurations offer tailored reach and digging capabilities: Option 1 provides a max cutting height of 29.2 ft and digging depth of 19.5 ft; Option 2 extends these to 30.2 ft and 21 ft respectively; Option 3 maximizes reach with a cutting height of 31.6 ft and digging depth of 22.7 ft. Maximum bucket capacity is 1.4 cubic yards, with a reference capacity of 1.1 cubic yards. The swing mechanism operates at 11.1 rpm, complemented by a swing fluid capacity of 2.2 gallons. Dimensional specifications include a transport height around 10.2–11.6 ft, length near 29 ft, a cab height of 9.5 ft, ground clearance of 1.5 ft, and tail swing radius of 8.3 ft, facilitating maneuverability and transportability. The hydraulic system features energy-saving boom and stick regeneration circuits. The 319D L also includes electronic controls for precision fuel delivery and efficient combustion, enabling high performance with lower emissions. Its welded box-section boom and thick multi-plate steel sticks ensure durability and long service life in demanding applications.
