AHC cranes
Active heave compensated (AHC) cranes stand for trouble-free operation in the most extreme conditions. PALFINGER delivers AHC offshore cranes ranging from smaller models for SOV’s to larger models for subsea lifts, in addition to special systems for module handling deployments. Tailor-made for the harsh offshore environment, they combine low power consumption with high performance. All components are placed as low as possible to ensure a remarkably low weight and low center of gravity. In combination with high lifting capabilities, this leads to a maximized cargo capacity on deck. Offering outstanding operator ergonomics and maintenance access, our active heave compensated cranes come with built in energy storage systems for AHC operations and an optimized drive train for correct speed, accuracy, and high capacity. For further increasing total energy efficiency, the crane can be delivered with our energy recuperation system allowing excess energy to be recuperated and returned to vessel grid.
