A pressure brake is a mechanical component that stops or decelerates moving parts in machinery. Commonly known as brakes or brakes. The Qiandai electromagnetic brake mainly consists of a brake frame, brake components, and control devices. Some electromagnetic brakes are also equipped with automatic adjustment devices for the clearance of brake components. In order to reduce braking torque and structural dimensions, electromagnetic 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.

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.
