Introduction to IHI HVL & HVK Hydraulic Motors

The IHI HVL and HVK series hydraulic motors are among the most widely used heavy-duty hydraulic drive motors installed on marine deck cranes, offshore cranes, cargo handling equipment, winches, and deck machinery systems.

These motors are designed to provide:

• High starting torque
• Smooth low-speed operation
• Excellent load holding performance
• Long service life
• Reliable operation under harsh marine conditions

Because of their rugged design and proven performance, many shipowners continue to operate HVL and HVK hydraulic motors even after decades of service.
