Technical Information
Hydraulic Motors in Excavators
Hydraulic motors are essential components in earthmoving equipment including excavators, backhoe loaders, skid-steer loaders, forklifts, heavy dump trucks, and bulldozers. These motors power hydraulic cylinders that extend and retract during various machine operations.
Excavator Swing Brake Operation
The swing brake features a multi-disc and plate assembly located in the first stage planetary gear assembly. This spring-applied, hydraulically-released brake functions as a parking brake only and is not designed for cyclic service braking. The discs and plates are lubricated by the release signal oil for optimal performance.
