The brake of the hoist is one of the important components, and each independent driving mechanism must have its own brake set. In the lifting mechanism, the brake is used to adjust the descending speed of the heavy object, brake and hold the heavy object, so that it can reliably hang in the air; In the walking mechanism, the brake is used to absorb the inertia in motion, causing it to stop walking within a certain braking distance.

There are many types of brakes for hoists, and they are generally selected based on the braking torque and usage. When the braking torque is not high, short stroke AC brakes or long stroke AC brakes can be selected; Long stroke (or double short stroke) AC brakes are used for high braking torque. Recently, electric hydraulic or electromagnetic hydraulic brakes have also been used to replace electromagnetic brakes.
When selecting the type of hoist, the following factors should be considered: gate form, seal size, and operating conditions, number of gate openings and gates of the same type, number of gate lifting ears, opening and closing force, opening and closing stroke, and opening and closing speed, as well as the opening and closing power status, setting location, spatial scale, and other operational requirements.
