Hydraulic winches easily transformed without expanding installed power

Existing rotating hydraulic winch systems are now easy to convert to the HeaveCom System.

New HYDAC technology saves on energy consumption, mass, nitrogen supplies, reduces wear throughout the entire system & extends the area of your application. Invite us to tell you more about the magic of our new HeaveCom System; your advantages, the costs and everything you need to know!

HYDAC Innovation

Ready for cost reduction? Invite us to tell you more about 'the magic'!

A small actuation cylinder, directly connected to the piston accumulator, compensates for the effi ciency losses. Oil fl ow to the winch motors is regulated based on a modified MRU-signal. The method results in an energy saving up to 85%. 

Existing rotating hydraulically driven winch systems are easy to convert to the Heave-Com System. Parallel installation of HYDAC AHC-drive on a winch system provides redundancy to the AHC-system. Direct wear throughout the entire system is reduced, since there is no more need for additional cable disks.

How does it work

Watch our presentation

An hydraulic winch with a variable displacement motor operates at a constant pressure difference regardless of the operating conditions. The constant load pressure allows for accumulation of the wave energy inside the HeaveCom cylinder. The cylinder is in force equilibrium with a constant nitrogen pressure on one hand and the constant load pressure on the other. The balance inside the accumulator allows for easy control with a small actuator. The system is actively controlled based on a modified signal from a motion reference unit.
