Crane brake function

• Support role: The original stationary objects remain at rest. For example, in the hoisting mechanism, the crane is kept stationary in the air; in the luffing mechanism of the boom crane, the boom is maintained at a certain position and remains stationary;
• Control purpose: Consumption of kinetic energy part of the movement through the friction into the friction heat, so that institutions quickly in a certain period of time or a certain course to stop the movement. For example, the brakes of each body in motion state.
