The brake will fail after running for a period of time. What are the solutions to the brake movement failure of crane accessories? When the lifting mechanism can't stop the heavy objects, walking, amplitude change, etc., it is not braked within the specified braking stroke, the movable joints in the brake system are stuck, and the oil on the brake friction plate is the most commonly encountered brake. failure. The effective solution is:
1. You can use oil to lubricate the joints of the equipment, and then use gasoline to clean the oil stains or replace the friction plates to effectively adjust the lock nuts of the equipment. Carry out the corresponding test.
2. The brake of the crane can be adjusted correspondingly to the stroke of the electromagnet, and the operating environment can be cleaned to ensure that it operates in a clean environment.
3. Maintenance of the brake wheel, the working surface roughness of the brake wheel should not be lower than Ra=16μm, HRC should not be lower than 50, and the depth should not be lower than HRC40 at 2mm;
4. Overhaul of brake pads of crane parts brakes: the amount of wear cannot exceed one-half of the thickness of the transport, and the rivets should sink more than 2 mm.
