JCB JS300 CRAWLER EXCAVATORS

Technical Description

The JCB JS300 is a robust hydraulic crawler excavator engineered for demanding construction and excavation applications. Powered by a 241 horsepower (180 kW) engine, this machine delivers exceptional productivity with a maximum digging depth of 24.9 feet and an impressive maximum reach along ground of 37.0 feet, making it suitable for a wide range of excavation tasks. Weighing approximately 73,826 pounds, the JS300 features a reinforced boom and dipper constructed from high tensile strength steel with internal baffle plates and heavy-duty wear strips for enhanced durability and longevity. The machine is equipped with an advanced open-centered, negative control hydraulic system featuring twin variable flow piston pumps that provide efficient flow-on-demand operation. It generates a massive 245 kilonewtons of bucket tearout force, enabling superior excavation capability and fast cycle times for maximum productivity in all applications. The fully hydrostatic three-speed track drive with autoshift provides tractive effort of 243 kN and gradeability up to 70 percent continuous, with travel speeds ranging from 2.1 km/h in low gear to 5.2 km/h in high gear. Standard features include servo-lever operated controls following ISO control patterns, a spacious and comfortable cab design, and comprehensive safety systems. The machine is equipped with a service brake featuring a hydraulic counter balance valve to prevent overspeeding on gradients, and a disc-type park brake with automatic hydraulic release. Optional equipment includes air conditioning, AdBlue systems, rearview cameras, and specialized piping for hydraulic hammers or shear attachments, making the JS300 a versatile solution for professional earthmoving operations.
