JCB JS370 CRAWLER EXCAVATOR

Technical Description

The JCB JS370 is a heavy-duty tracked excavator engineered for demanding construction and excavation applications. This mid-range machine delivers exceptional strength, productivity, and efficiency through its closed box section revolving frame construction, which increases structural integrity while reducing operational stress and impact damage. The excavator is powered by a highly efficient MTU or Isuzu diesel engine producing 281 gross horsepower (210 kW) at rated power, compliant with Tier 4 Final emission standards for environmental responsibility. With an operating weight of approximately 85,156 lbs (38,626 kg), the JS370 provides substantial mass for stable operation in challenging terrain. The machine delivers a maximum digging depth of 26.5 feet (8.08 meters) and an impressive maximum reach along the ground of 38.6 feet (11.78 meters), making it versatile for deep excavation and extended reach applications. The bucket tearout force reaches 59,754 lbf (265.8 kNm), delivering up to 12% greater productivity compared to competing models in its class. Standard bucket capacity ranges from 1.6 to 2.0 cubic yards, with expandable options available. The JS370 incorporates reinforced boom and dipper construction using high-tensile strength steel with internal baffle plates for extended durability. Its fully-welded X-frame undercarriage provides maximum load distribution and longevity in demanding applications. Four operating modes—light, general, heavy, and heavy plus—allow operators to optimize performance for specific tasks. Centralized grease points facilitate safe and efficient maintenance, while individual serviceable radiator and cooler components enhance accessibility and reduce downtime during maintenance operations.
