As we know that a crane is a large-scale machinery and equipment, which requires a lot of work every day. In its various mechanisms, the brake is very important and is an indispensable part to ensure the safe operation of the crane. When braking, it is an important component used to ensure the accurate, reliable and safe operation of the crane.
The braking device of the lifting mechanism ensures the stop position of the hanging object, and can keep the hanging object in this position after the lifting mechanism stops running, which plays a role in preventing the heavy object from falling.
In addition to the braking devices of the operating mechanism and other mechanisms to achieve stopping and staying in the resting position, under special circumstances, the operating speed of the mechanism can also be reduced or adjusted according to work needs.
Crane brake device is usually composed of crane brake, brake wheel and brake drive device. Including adjustment of working stroke, adjustment of braking force, adjustment of braking clearance in three aspects of adjustment work. It realizes mechanism braking through the principle of friction.
When the friction part of the brake set on the stationary frame presses against the friction part on a certain operating shaft of the mechanism with a certain force, the friction force generated between the two contact surfaces produces a friction moment on the axis of rotation. Torque is usually called braking torque.
When the braking torque is balanced with the torque generated by the torsion force during the operation of the crane, the braking requirement is reached.
