Failure analysis of the brake of cantilever hoisting tool in clean room workshop

The brake is an important safety component of the cantilever hoisting tool in the clean workshop, which has the function of preventing the hanging objects from falling and realizing the parking function. Only good brakes can ensure the accuracy and safety of clean boom lifts. In the operation of the cantilever crane in the clean workshop, there will be mechanical failures such as insufficient braking force, sudden failure of the brake, excessive temperature of the brake wheel, smoke from the brake pad, and unsealing of the brake arm. So what caused this mechanical failure? Learn more about it below!

The reasons for the failure of the cantilever hoisting tool brake in the clean workshop are as follows

Excessive wear of the brake band or brake wheel; part of the brake band falling off; the main spring is too loose; there is grease between the brake band and the brake wheel; there are clamps or excessively worn parts outside the living hinge; lock nut Looseness; impeller hydraulic push rod tensioner R is not flexible; brake pads are not flexible. Serious or large pieces fall off, or the long-stroke electromagnet is stuck, the main spring fails, or the main components of the brake are damaged; the adjustment of the gap between the brake and the shim is too large or too small; the hinge is stuck or the braking torque is too large, or the hydraulic push rod is loose Lack of oil, air mixture, or hydraulic pressure in the cylinder. The grease used in the pushrod release brake is not acceptable, or there is dirt between the brake pads and the brake wheel.

Preventive measures: Regularly check and maintain the brake of the cantilever crane in the clean workshop, the brake of the hoisting mechanism must work once a day, and the brake of the running mechanism should be checked once a day. The main contents are as follows: whether the hinge is stuck and worn, whether the fastening point is loose; whether the movement of the moving parts is normal; whether the hydraulic system is normal; whether the wear of the brake wheel and the brake band is normal and clean.

According to the inspection situation, determine whether the brake is normal, and resolutely do not work with illness, and at the same time, the brake should be lubricated and maintained regularly. In order to ensure the safe operation of the crane in the clean workshop, the brakes must be adjusted frequently to ensure the working requirements of the corresponding institutions.
