Crane brake working principle:

Although the crane brakes vary according to the type of job requirements, the function in the gantry crane is the same. It's mainly by controlling the rotation of the motor and the inertia movement so that the control device can be parked, accelerated or decelerated in a state of motion.

In conclusion, a crane brake not only serves a control purpose, but also functions as a safety device. With the brake, a hoist can speed up or slow down its vertical motion as well as control the rising or lowering goods to stop stably at a required height. Another use of the brake is in the crane traveling or luffing mechanism, where it allows the mechanism to stop at a pre-set location.
