Travel Motor
Technology Innovation
Technological innovation creates values.
Travel motors are core elements forming the power trains of excavators.
Piston pumps that form the oil pressure using engine power and main control valves convey the oil pressure to each part. Travel motors are hydraulic motors that increase driving power properly for the travel conditions of excavators using oil pressure, maintain adequate speed, shift the gears to move forward or backward, and convey or cut off power.
