CATERPILLAR 320C LN CRAWLER EXCAVATOR

Technical Description

The Caterpillar 320C LN hydraulic excavator is a versatile, medium-sized machine designed for efficient digging and loading operations. It is powered by a Cat 3066 ATAAC diesel engine delivering a net power output of 138 hp (103 kW) at 1800 rpm. Operating weight ranges around 48,000 lbs (21,800 kg), offering a balance of power and stability suitable for various earthmoving tasks. The excavator features four boom and stick configurations, each providing differing performance characteristics: the first option offers a maximum digging depth of 13.7 ft and a maximum reach along the ground of 30.7 ft, while the fourth option extends digging depth up to 19.6 ft and a maximum reach of 36.6 ft, allowing for deep excavations and extended reach work. Maximum cutting heights span from 35.6 ft to 40.7 ft, and loading heights range from 25.3 ft up to 31.7 ft depending on the boom/stick option. The unit’s bucket capacity varies between 0.7 to 1.8 cubic yards, with a reference capacity of 1.1 cubic yards, providing flexibility for a range of material handling needs. The undercarriage includes 19.7-inch wide shoes and a track gauge of 6.6 ft, with a length of track on ground of 12 ft, designed for optimal stability and ground pressure distribution. Maximum travel speed is 3.5 mph, and the drawbar pull capacity reaches 44,062 lbs, allowing the machine to effectively maneuver on site. Key dimensions include a ground clearance of 1.6 ft, overall height to cab top of 9.7 ft, width of 8.2 ft, and variable shipping lengths from around 30.8 ft to 33 ft, facilitating transport logistics. The hydraulic system delivers robust digging and lifting forces, supported by durable structural components suited to demanding construction and excavation applications.
