JCB JS300NLC CRAWLER EXCAVATOR

Technical Description

The JCB JS300NLC excavator is a robust mid-size hydraulic excavator designed for high productivity and versatility across various earthmoving applications. Powered by a turbocharged, intercooled MTU 6R1000 engine producing 281 hp (210 kW) at 2000 rpm, it is Tier 4 Final compliant, ensuring modern emissions standards. The machine operates at a weight of approximately 71,053 lbs (32,229 kg) with a standard fuel capacity of 155.9 gallons and an efficient 24-volt electrical system supported by a 100 Amp alternator and dual 12-volt batteries. The JS300NLC offers multiple boom and stick configurations allowing flexibility in reach and digging capabilities. Option 1 features a maximum digging depth of 21 ft, a cutting height of up to 32 ft, and a digging reach of 33.1 ft, with a minimum swing radius of 184 in. Subsequent configurations increase depth and reach, with the fourth option achieving a max digging depth of 27 ft and a max digging reach of 38.7 ft, optimizing loading and material handling heights near 24.5 ft. The machine sustains a max vertical wall digging depth up to 23.4 ft depending on configuration. Hydraulically, it is equipped with a high-flow system delivering 153.3 gpm at relief valve pressure up to 4627 psi, enabling powerful bucket tearout forces up to 245 kN. Fully hydrostatic, the travel system features a three-speed autoshift drive capable of 3 mph speed with a drawbar pull of 54,904 lbs and ground pressure at 9.1 psi. The undercarriage includes 24-inch shoes, nine carrier rollers per side, and a 7.5 ft track gauge. Braking is managed via a hydraulic counterbalance valve and an automatic spring-applied disc park brake. The excavator’s bucket capacity ranges from 1.6 to 2.5 cubic yards, with a reference capacity of 2 cubic yards, suited for large-scale digging and loading operations. Structural durability is enhanced by high tensile steel booms and wear-resistant plates, ensuring long service life. The cab height is 9.9 ft with a shipping height under 12 ft to aid transport logistics. Overall, the JCB JS300NLC combines powerful performance, advanced hydraulics, and adaptable configurations for demanding excavation tasks.
