A pressure brake is a brake that is achieved by pressing the brake pads against the brake wheels. A single brake block exerts a large and uneven pressure on the brake wheel axle, so an additional pair of brake blocks is usually used to counteract the pressure exerted by the brake blocks on the brake wheel axle.

In order to reduce braking torque and structural dimensions, brakes are usually installed on the high-speed shaft of equipment, but for large equipment with high safety requirements (such as mine hoists, elevators, etc.), they should be installed on the low-speed shaft near the working part of the equipment. Some brakes have been standardized and serialized, and are manufactured by professional factories for selection.
