The WDM Series Two-Speed Walking Motor is a high-performance hydraulic solution engineered specifically for crawler and wheeled driven vehicles, self-walking machinery, winches, and roller lifting equipment. By integrating a specialized cycloid hydraulic motor with a compact structural design, the WDM series allows for seamless integration into track wide grooves or winch drums, significantly optimizing space utilization and simplifying the overall installation process.
Designed for versatility, these motors are compatible with both open and closed hydraulic loop systems. The standout feature of the WDM series is its hydraulic control capability, allowing users to switch between high and low speeds with a precise 1:2 speed ratio. Combined with a robust sealing system for radial and axial stability, the WDM series ensures reliable power delivery and long-term durability in demanding industrial environments.
