Rexroth A6V & A6VM Series Heavy-Duty Hydraulic Motors for Cranes

Product Overview: The Rexroth A6VM and A6V series axial piston variable displacement motors are the global power standard for crane winches, slewing mechanisms, and travel drives. This series spans a comprehensive displacement matrix from 107cc (A6V107) to the heavy-duty 160cc (A6VM160). Featured models like the A6VM160EZ2/63W-VZB020HB utilize advanced EZ2 electric proportional control for an extremely wide speed modulation range. Additionally, the paired A4VSO355EO2/30R-PPB25N00 high-displacement pump provides stable high-pressure power for the entire system. Renowned for their “Superior Starting Torque” and “Fine-Tuning Performance,” these motors ensure smooth movements and precise positioning during heavy lifting operations.

Key Technical Advantages:

• Wide Speed Regulation Range: The A6VM series allows displacement adjustment from maximum to zero, providing high speed ratios for fast empty-hook cycles and slow, precise heavy-load lifting.

• High Starting Torque Efficiency: Patented spherical valve plate design ensures high mechanical efficiency at ultra-low speeds, effectively preventing load slippage.

• High-Pressure Robustness: Rated at 350-400 Bar continuous with peaks up to 450 Bar, specifically reinforced to handle the shock loads typical of crane lifting.

• Precision Control Modes: Supports EZ (Electric Proportional), HA (Automatic Pressure), and HD (Hydraulic) controls, seamlessly integrating with modern crane bus-control systems.

• Longevity & Reliability: Built with heavy-duty bearings and reinforced piston groups to maintain long service intervals even in harsh 24/7 environments like ports and crawler crane sites.
