Poclain MS125 & MS50 Heavy-Duty LSHT Radial Piston Motors

Product Overview: The Poclain MS125 and MS50 Series represent the pinnacle of power in radial piston hydraulic motor technology. As premier high-displacement LSHT (Low Speed High Torque) motors, they are engineered to directly drive heavy-duty wheeled or tracked equipment without the need for external reduction gearboxes. This category features high-precision models: MS125 (Ultra-Torque) and MS50 (Industrial Heavy-Duty). These motors are the definitive power units for mining machinery, large rotary drilling rig heads, port machinery winches, and travel systems for 30+ ton construction vehicles.

Key Technical Advantages:

• Explosive Torque Delivery: The radial piston architecture ensures massive torque output even at ultra-low speeds or during startup, with starting efficiency near 100%.

• Extreme Mechanical Resilience: Reinforced housings and oversized tapered roller bearings allow these motors to sustain massive axial and radial forces, functioning as direct load-bearing hubs.

• Flexible Functional Integration:

  • Supports Fixed or Dual Displacement (2-Speed) shifting to balance heavy-duty work and high-speed transport.

  • Fully compatible with integrated multi-disc parking brakes and high-precision speed sensors.

• High Pressure & Longevity: Rated for a continuous pressure of 400 Bar with peak capabilities reaching 450 Bar (6500 PSI), ensuring stability under intense shock loads.

• Target Applications: Heavy loaders, railway maintenance vehicles, marine deck machinery, and underground tunneling equipment.
