CATERPILLAR 320D LRR CRAWLER EXCAVATOR

Technical Description

The Caterpillar 320D LRR is a versatile long-reach hydraulic excavator engineered for demanding earthmoving and material handling applications. Powered by a Cat C6.4 ACERT engine producing 148 horsepower and 110 kilowatts, this mid-sized excavator delivers robust performance in compact configurations. The machine features an advanced hydraulic system with maximum equipment pressure of 5,076 psi and a pump flow capacity of 54 gallons per minute, enabling increased stick and bucket forces approximately 7% higher than previous models for superior digging capability. With a maximum drawbar pull of 46,311 pounds, the 320D LRR excels in slope climbing and poor ground conditions. The long-reach boom configuration accommodates three bucket-and-stick combinations, ranging from a 18 ft 7 in boom with a 12 ft 8 in stick achieving 32.6 feet cutting height, to a more compact 18 ft 7 in boom with an 8 ft 2 in stick for tighter working spaces. The reference bucket capacity measures 1.4 cubic yards. Operating at 52,249 pounds, the excavator maintains a 10.5-foot track width and generates 11.5 rpm swing speed for efficient material placement. The cab features SAE J1356 FEB88 standards with operator comfort visibility. An innovative heavy-lift function increases system pressure to 36,000 kPa, providing additional front-end lift capacity while automatically reducing engine speed for enhanced load control. The 77-gallon fuel capacity and 56-gallon hydraulic system capacity support extended operation cycles, making the 320D LRR suitable for construction, demolition, and aggregate industries.
