What is the IHI HVK Series Hydraulic Motor?

The HVK Series is a hydraulic vane motor family engineered specifically for hoisting applications. These motors convert hydraulic energy into rotational mechanical power used to drive crane drums, lifting mechanisms, and hydraulic winches.

Unlike conventional hydraulic motors, HVK motors are optimized for low-speed, high-torque operation, making them ideal for cargo handling and heavy lifting systems where precision and safety are essential.

The series is commonly installed on:

  • Marine Deck Cranes
  • Cargo Cranes
  • Offshore Cranes
  • Hydraulic Winches
  • Heavy Lift Systems
  • Specialized Deck Machinery

Main HVK Series Models
