Key Features of WTM-03 Hydraulic Travel Motor

This hydraulic final drive motor model is a 2-speed swash-plate hydraulic travel motor, but a single-speed model is optional.

It is integrated with a planetary reducer converting the high-speed, low-torque output of the hydraulic motor into low-speed, high-torque output suitable for driving the machine’s tracks or wheels.

AKD (Auto Kick Down) is optional to enhance the efficiency and productivity of the machine by automatically adjusting the hydraulic motor’s output torque and speed based on the current load and operational requirements.

A parking brake is designed to securely hold the machine to prevent unintended movement when the hydraulic system is not actively engaged.
