AHC Cranes

Reliable Lifting in the Harshest Offshore Conditions

PALFINGER active heave compensated (AHC) cranes ensure smooth, trouble‑free operation even in extreme environments. Designed for SOVs, subsea lifts, and module handling deployments, they deliver high performance with low power consumption – perfectly tailored for demanding offshore applications.

Lightweight Design for Maximum Deck Capacity

All major components are positioned low within the crane structure, resulting in a low center of gravity and optimized overall weight. Combined with powerful lifting capabilities, this design maximizes available cargo capacity on deck while maintaining superior stability.

Intelligent Energy Use and Effortless Control

Featuring built‑in energy storage systems and an optimized drive train, PALFINGER AHC cranes deliver exceptional speed, accuracy, and lifting capacity. For even greater efficiency, the optional energy recuperation system recovers excess energy and returns it to the vessel’s grid, reducing overall power consumption.
