- 100% OEM Genuine: Manufactured by Mottrol, the original supplier for Doosan undercarriage components.
- Multi-Stage Planetary Gears: Optimized gear ratio delivers maximum torque multiplication for heavy loads.
- Reinforced Housing: High-strength cast iron shell resists impact and deformation in mining conditions.
- Premium Bearing System: Heavy-duty tapered roller bearings ensure smooth rotation under extreme loads.
- Integrated Parking Brake: Built-in spring-applied brake provides reliable holding force on slopes.
- Sealed Design: Multi-layer sealing prevents oil leakage and contamination from dust/water.
🧠 How It Works
The hydraulic travel motor (mounted on the reducer) converts hydraulic flow into high-speed, low-torque rotation. This rotation enters the travel reducer, where a sun gear drives multiple planet gears inside a stationary ring gear. The planet carrier outputs a much slower rotation with massively increased torque — exactly what a 50-ton excavator needs to crawl over rocks, climb grades, and reposition efficiently. The integrated brake locks the output shaft when no pilot pressure is present, preventing unwanted movement.
