The unique patented system known as the Hydrodynamic System offers an easy and rational solution for numerous hose reel and cable applications. The system is based on a torque unit which has a clutch, brake and reduction gear built into one closed unit. An even torque output is guaranteed due to the clutch acting directly on the main drum shaft.
Another type of system called the Cavotec Torque Control System is provided by Cavotec Specimas which gives a continuous pull on the cable following a torque reference signal based on the speed, acceleration, weight and length of the cable. The cable lifetime is significantly improved which is the key benefit of this system. The system is able to be used for DC feed, single phase and three-phase AC.
