A crane brake pulley is a metal wheel with a wide rolling surface, which works as part of the brake system of the crane mechanism and serves to hold the shafts of electric motors and gearboxes when the drive is not running.

Serially and to order brake pulleys with a diameter of D = 160, 200, 300, 400, 500, 600 mm, (material - steel 45 (forging)), production time up to 10 working days. If you find it hard to determine which standard size of the brake pulley you need, we will make the necessary calculations and restore the product design.

The brake pulley is being installed between the motor shaft and the gearbox input shaft, or on the back of the gearbox input shaft. Mostly, it is used when working in conjunction with shoe brakes, it is held stationary due to the frictional force that arises from the pressing action of the brake shoes of the brake.
