Poclain MS11 & MSE11 Heavy-Duty LSHT Radial Piston Motors

Product Overview: The Poclain MS11 Series is a high-performance, modular cam-lobe radial piston motor engineered for extreme environments. Known for its exceptional power density, the MS11 delivers massive torque within a compact installation envelope. This category highlights precision configurations: MS11-2-D21-R11-1212-5EJ0 (with R11 wheel flange) and MS11-2-G21-F12-1510-5000 (with F12 industrial flange). These motors are the industry choice for rotary drilling rig heads, concrete mixer drives, vibratory roller travel systems, and various medium-to-heavy lifting winches.

Key Technical Advantages:

• Elite Low-Speed Stability: The multi-piston radial design ensures consistent, smooth torque output even at minimal RPMs, eliminating pulsation and “creeping.”

• Dual Displacement Options (MS11-2): Supports on-the-fly displacement shifting to balance high-torque climbing needs with high-speed travel requirements.

• Superior Load Resistance: Purpose-built to withstand intense radial and axial shock loads, allowing the motor housing to act as a primary load-bearing component.

• High-Pressure Reliability: Rated for continuous operation up to 450 Bar, featuring a reinforced cam-ring for an extended service life.

• Technical Spec Decoding:

  • D21 / G21: Relates to the distributor plate type and control signal interface configurations.

  • R11 / F12: Represents different mounting standards—R11 for wheel drives and F12 for industrial or gearbox mounting.

  • 1212 / 1510: Corresponds to the cam-ring profile determining specific displacement capacity.
