Poclain HMCR & HMCRE Motor | HMCRE05, HMCR03, HMCR05-1-11A | Radial Piston Motor

Poclain HMCR & HMCRE Series High-Performance Radial Piston Motors

Product Overview: The Poclain HMCR and HMCRE Series are radial piston motors specifically engineered for compact, heavy-duty drive applications. Based on Poclain’s legendary cam-lobe technology, this series is deeply optimized for extremely restricted installation spaces. This selection features two core configurations: HMCRE05-1-11A-B02-2A20-F2-1 (Enhanced compact motor) and HMCR03-2-11A-A03-2A20 (Dual-displacement versatile type). These motors are the premier choice for skid steer loaders, municipal sweepers, mini-excavator travel systems, agricultural propulsion, and various closed-loop hydrostatic circuits.

Key Technical Advantages:

• Ultra-Compact Engineering: The HMCRE series compresses axial dimensions even further compared to standard MS models, making it ideal for narrow-track vehicles.

• High Starting Torque Efficiency: Optimized cam curves ensure superior mechanical efficiency at low speeds, minimizing power loss during machine start-up.

• Rugged Shock Resistance: The robust radial piston architecture directly absorbs impact loads from rough terrain, eliminating the need for additional dampening components.

• Dual-Displacement (2C) Control: The HMCR03-2 model enables seamless displacement shifting, allowing machines to switch between high-torque work mode and high-speed travel mode.

• Extreme Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, handling instantaneous heavy loads in harsh conditions.

• Target Applications: Compact wheel drives, crawler drive systems, auxiliary drives, forestry cutter heads, and specialized municipal vehicles.
