Crane brake type classification:
Commonly used crane brakes include spring-type short-stroke electromagnet double-shoe brakes, referred to as short-stroke brakes (single-phase brakes); spring-type long-stroke electromagnet double-shoe brakes, referred to as long-stroke brakes (three-phase brakes); hydraulic push rods Type double brake shoe brake, referred to as push rod type brake. The brake plays an indispensable role in the escort of the crane. It can be said that if the brake device is not installed in the crane, then just like the car has no brake function, parking under the action of inertia is a serious hidden danger.
Crane brake maintenance:
The role of the crane brake in the equipment is so important, so we need to pay more attention to the maintenance of the brake in the daily use process: regularly check whether the brake is in good working condition, and can find that the existing safety hazards are reduced in time Crane accident rate occurred. Identify whether there are abnormalities in the brake equipment by sound, and regularly check the inside of the crane brake to see whether the wear condition is beyond the allowable range, whether the spring is invalid, whether there are more impurities and dirt in the internal parts, etc., must be timely Clean or replace internal components.
