Travel motor OVERVIEW

Hydraulic travel motor (also named final drive, track motor) is an integrated crawler driving unit, combining axial piston hydraulic motor, multi-stage planetary reducer and built-in spring parking brake as one compact assembly. It converts hydraulic pressure into low-speed high-torque mechanical power to drive crawler undercarriage of construction machinery. Equipped with two-speed shifting function, it switches freely between high-torque climbing mode and fast flat-ground travel mode, delivering stable, smooth and efficient driving performance for all-terrain working conditions.

Features and Benefits

• Dual-speed adjustable design: Low speed for steep slope climbing & heavy load dragging; high speed for flat-site quick transfer;

• Ultra-compact integrated structure: Easy installation, small occupation space for mini to large crawler machines;

• Heavy-duty durable parts: High-strength cast housing, hardening gear teeth, imported floating oil seals to reduce leakage failure;

• Low noise & stable running: Precision matching internal components, less vibration during frequent forward/reverse switching;
  

• Full OEM interchangeability: Perfectly replace original travel motors of CAT, Komatsu, Hitachi, Volvo, Doosan, Sany, XCMG and other mainstream excavator brands;
  

• Strict factory testing: Every unit undergoes pressure, speed and leakage test before delivery, test videos available upon request.

Travel motor FAQ:

1. What is the Travel motor ?

A travel motor, also known as final drive, is an integrated hydraulic drive assembly for crawler‑type machinery. It consists of an axial piston hydraulic motor, multi‑stage planetary reducer and built‑in spring parking brake. It converts hydraulic energy into low‑speed high‑torque mechanical power to drive vehicle tracks. Most models support two‑speed shifting for climbing and fast travelling. Widely used on excavators, crawler loaders, drilling rigs and other tracked construction equipment.

2. What makes the Travel motor ?

3. What is the working pressure range of Travel motor ?

The rated working pressure of travel motor ranges from 21 MPa to 34.5 MPa, and the peak pressure can reach up to 37 MPa. The two‑speed control pressure is 2‑7 MPa, and brake release pressure is 1.6‑3.9 MPa. Specific values vary according to different motor models and matching machine tonnages.
