CATERPILLAR 314D CR CRAWLER EXCAVATOR

Technical Description

The Caterpillar 314D CR is a compact hydraulic excavator engineered for precision digging and material handling in confined spaces. Powered by a Cat C4.2 ACERT engine delivering 97 gross horsepower (90 net SAE), this machine features a 259.4 cubic inch displacement engine with advanced emission controls meeting EPA Tier 3 and EU Stage IIIA standards. The unit operates at an optimized hydraulic system pressure of 5,076 psi with a pump flow capacity of 5.6 gallons per minute, ensuring efficient power delivery across all functions. With an operating weight of approximately 30,865 pounds and a compact tail swing radius of just 4.9 feet, the 314D CR excels in restricted job sites where maneuverability is critical. The excavator accommodates three interchangeable stick configurations—2.5 meters, 2.8 meters, and 3.0 meters—providing maximum digging depths ranging from 16.2 to 19.5 feet and horizontal reaches up to 28.4 feet, depending on configuration selected. The boom and stick utilize electronic regeneration circuitry that conserves energy during boom-down and stick-in operations, reducing fuel consumption and operating costs. Standard bucket capacities range from 0.4 to 1.0 cubic yard, with a reference capacity of 0.6 cubic yards, accommodating diverse material handling applications. The carbody features an X-shaped box section design for superior torsional rigidity, while robot-welded track roller frames deliver exceptional durability. Advanced hydraulic cross-sensing utilizes dual pumps to maximize available hydraulic horsepower under all operating conditions, enhancing productivity through faster implement speeds and stronger pivot turns. Ground pressure of 6.6 psi with 19.7-inch shoe width minimizes ground disturbance, making this excavator suitable for sensitive environments.
