Electro Magnetic Brakes By Crane Control Equipments

Crane Control Equipments make Electro Magnetic Brakes are suitable for AC supply up to 400 to 440 volts, and are available for a wide range of Drum sizes from 10mm to 380mm Dia.

These brakes are available with a rated torque ranging from 200 Kg cm for the smallest brake (100mm Dia) up to 6900 kg cm for a 380mm dia at 50% coil rating i.e. the coil remains in circuit for a maximum of 5 min out of every 10min.

These brakes are conventionally termed as single phase EN Brakes although they are to be operated on 2 phase.

3 Phase Brake are also available where a higher torque is desired.

Since these brakes are in normally closed position, the release of the Brake shoes is effected by energizing the Electro Magnetic coil which over comes the spring force and the shoes are moved clear off the drum by lever/arm linkage system so that the drum is free to rotate without any friction.
