What Are The Reasons For The Mechanical Failure Of The Brake? How To Prevent It?

Causes of mechanical failure of the brake:
a. The brake belt or brake wheel is too worn; the brake belt has a small piece of part off; the main spring is adjusted too loose; there is grease between the brake belt and the brake wheel; there is a stuck place outside the movable hinge or There are parts with excessive wear; the lock nut is loose and the whole tie rod is loose; the impeller of the hydraulic push rod brake release device does not rotate flexibly;
b. The brake pads are severe or a large piece falls off, or the long-stroke electromagnet is stuck, the main spring fails, or the main parts of the brake are damaged;
c. The gap between the brake and the gasket is adjusted too large or too small;
d. The hinge is stuck or the braking torque is adjusted too large, or the cylinder of the hydraulic push rod brake release is short of oil and mixed with air, or the grease used for the hydraulic push rod brake release does not meet the requirements, or the brake pads There is dirt between the brake wheel and the brake wheel.
2 Precautions
Check and maintain the brakes on a regular basis. The brakes of the lifting mechanism must be performed once a shift, and the brakes of the operating mechanism must be performed once a day. The main inspections are as follows:
a. Check whether there is stagnation and wear at the hinge, and whether there is any looseness at each fastening point;
b. Whether the action of each movable part is normal;
c. Whether the hydraulic system is normal;
d. Whether the wear between the brake wheel and the brake band is normal and clean.
Determine whether the brake is normal according to the inspection situation, resolutely put an end to running with a disease, and at the same time lubricate and maintain the brake regularly. In order to ensure the safe operation of the crane, the brake must be adjusted frequently to ensure the working requirements of the corresponding mechanism.
