Hitachi excavator HMGF40FA ZX200-3 final drive 9257254 9258325 travel motor assy

The excavatortravel motor assembly is a critical component of the machine’s chassis system, responsible for supporting the entire weight and providing mobility. It typically consists of tracks, sprockets, idlers, rollers (carrier and track), and travel motors. The design of the undercarriage directly impacts the excavator’s stability, traction, and operational efficiency. A high-quality undercarriage ensures smooth movement across rough terrain, minimizes slippage and wear, and offers excellent durability for demanding applications in mining, construction, and agriculture.

Working Principle

The undercarriage is driven by the hydraulic system, which powers the travel motor to rotate the sprocket, propelling the track. The idler wheel and carrier rollers ensure proper track movement, while track rollers prevent sagging. The track frame maintains overall stability, allowing the excavator to move flexibly across rough terrain.
