Poclain MK Series High Power Density Radial Piston Motors

Product Overview: The Poclain MK Series is an advanced evolution of the classic MS range, specifically developed for higher power density and more demanding operational environments. As a premier Low Speed High Torque (LSHT) drive unit, the MK series utilizes optimized internal geometry to deliver significantly higher torque within a compact installation envelope. This category features high-precision models: MK08, MK18, and the large-scale MK47. This series is the definitive power source for heavy-duty wheeled loaders, railway machinery, large agricultural harvesters, mining rigs, and industrial mixing drives.

Key Technical Advantages:

• Elite Torque Output: Provides higher specific torque compared to standard motors of the same size, ideal for heavy-duty travel systems requiring extreme tractive effort.

• Optimized Speed Spectrum: Features a specialized distributor valve design that maintains superior efficiency and minimizes heat generation during high-speed operations.

• Compact & Rugged Architecture: Reinforced housing design capable of withstanding extreme axial and radial loads, allowing the motor to act as a direct load-bearing hub.

• Integrated Functionality: Easily configurable with integrated multi-disc parking brakes, speed sensors, and 2-speed displacement shifting capabilities.

• Target Applications: Rotary drilling rigs, heavy roller drives, forestry harvesters, and underground mining vehicle travel drives.
