Crane Control Equipments makes AC Electromagnetic Brakes that 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. We stand in the midst of prominent Electromagnetic Brakes Suppliers based in India. Our Heavy Duty AC Electromagnetic 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 10 min.
These brakes are conventionally termed as single phase EM 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 affected by energizing the Electro Magnetic coil, which overcomes 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.
When the power in given to the Electro Magnetic coil the coil gets energized and in turn pulls the plunger down. The plunger in turn operates the arm of the brakes and the brake opens.
The design of the brake is such that as the lining keeps wearing out due to normal operation of the brake, adjusts itself on its own to achieve the rated toque. When specified, brake drum or drum coupling both pin bush type and flexible geared type can be supplied along with the brakes.
