The excavator features a variable swash axial piston travel motor and planetary reduction final drive for reliable traction and durability, with a high travel speed of 4.1 mph and a low speed of 2.4 mph. The operating weight is 31,499 lbs, providing excellent stability during operation. The JS131 is equipped with a hydraulic counterbalance valve for the service brake and a spring-applied, automatic hydraulic release disc-type parking brake. Its hydraulic system offers high-pressure relief settings for the boom, arm, bucket, swing, and travel circuits, ensuring smooth and powerful performance. The cab is designed for operator comfort, with features such as a spacious layout, ergonomic controls, and low noise levels. With its combination of power, reach, and reliability, the JCB JS131 is a top choice for contractors seeking a high-performance excavator for diverse applications.
