The drive to the reel is by means of chains and sprockets, with single or double reduction accordingly to requirements. They can handle length up to 150 Mtrs multicore cables can be used. The access to the weatherproof sliprings and brush gear is by means of an easily removable cover situated at the non driving end of the reel. These units are specially designed for automatically handling trailing cables supplying power to the long travel motion on overhead and gantry cranes. Motors used are squirrel cage as well as slipring construction. Selection of motor is depends upon torque requirement. Output torque of motor can be reduced in the slipring motor by increasing the rotor resistance.
