SYNOPSIS
These brakes designed by controlling for equipment,
auto mobiles and movers are suitable for AC & DC supplies up to 12V to
220V, and are suitable for a wide range of drum sizes 10 to 380mm dia. These brakes are suitable with a rated torque
ranging from 100 kg-cm for the smallest brake up to 2000 kg-cm for a 380 mm dia
at 50% coil rating, i.e., the coil remains in circuit for a maximum of 5 min.
out of every 10 min.
Since these brakes
are in normally closed position, the release of the brake shoes is affected by
energizing the electromagnetic coil which overcomes the spring force and 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 is given to the electromagnetic coil the coil gets
energised 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.
