How often should the brakes of overhead cranes be checked?

Common problems of bridge crane brakes:

The main brake spring is damaged or adjusted too loosely, and the braking torque is insufficient; The excessive wear of the brake shoe exposes the cap nails, resulting in insufficient friction, and the brake cannot brake heavy objects; 

The brake lever lock nut is loose, the lever moves, or the joints of the lever system are stuck, etc., which will affect the brake. Bridge crane brakes should be inspected once per shift, inspection standards: 

The brake should act accurately, and the pin should not be stuck. 

The brake shoe should fit the brake wheel correctly, and the gap between the brake shoe should be equal when the brake is released; the wheel rim and tread should be checked regularly. 

When the rim wear or crack reaches 10% of the thickness, a new wheel should be replaced. 

The bridge crane pulley block mainly checks the wear of the rope groove, whether the rim is cracked, and whether the pulley is stuck on the shaft. 

Check the spreader regularly; the working performance and service life of each organization of the smooth bridge erection machine mainly depend on the smoothness.
