Poclain MK08 & MK18 Compact LSHT Radial Piston Hydraulic Motors

Product Overview: The Poclain MK Series is a masterpiece in the realm of high-performance Low Speed High Torque (LSHT) hydraulic drives. Specifically engineered for heavy-duty applications with severely restricted installation space, the MK series delivers the same massive torque as the MS series but within a significantly shorter axial envelope. This page highlights two elite configurations: the heavy-duty MK18-2-D21-F19-1340 and the high-efficiency MK08-8-124-F08-1340-8AD0. Renowned for their modularity, these motors are the premier choice for skid steer travel drives, combine harvesters, rotary drilling heads, and municipal sanitation machinery.

Key Technical Advantages:

• Elite Compact Design: The MK series features an ultra-short axial length, allowing for perfect integration into narrow wheel hubs or compact frames, maximizing machine design flexibility.

• Tiered Generation Technology:

  • Series 2 (e.g., MK18-2): Enhanced back-pressure tolerance and optimized efficiency under high-pressure duty cycles.

  • Series 8 (e.g., MK08-8): A high-performance version offering increased speed potential and power density.

• Integrated Heavy-Duty Braking: Modular housings integrate multi-disc wet parking brakes (e.g., F19, F08 specs), ensuring absolute safety for incline holding in harsh conditions.

• Superior Low-Speed Control: Patented cam-ring technology ensures constant torque output even at speeds near 0 RPM, eliminating “stick-slip” for millimeter-precision maneuverability.

• Reinforced Bearing Structure: Heavy-duty internal tapered roller bearings handle massive radial loads and operational shocks directly from the vehicle weight.

• Target Applications: Wheel loader travel drives, forestry harvester heads, port material handlers, and specialized construction chassis.
