Introduction

The IHI HVKG, HVKP, HVN, HVN-SS, HVN-A, HLA, HKA, HNK and HNS hydraulic motors represent some of the most important hydraulic drive units used in Japanese marine hydraulic systems.

These motors are commonly installed in:

• IHI Deck Cranes
• IHI Cargo Cranes
• IHI Offshore Cranes
• IHI Windlasses
• IHI Mooring Winches
• IHI Hatch Cover Systems
• Heavy Deck Machinery

Because many vessels still operate these hydraulic systems today, marine engineers frequently search for these exact model numbers when sourcing replacement units, repair kits, seal kits, bearings and overhaul components.

SM MARINE SERVICE™ actively supports vessel owners, ship managers and repair companies requiring IHI hydraulic motors and spare parts.
