Mini electric hoist brake pressure spring fatigue caused by prolonged use
If the mini electric hoist is disabled for a long time, someone may start adjusting the brake adjusting nut by mistake, or the brake ring may be worn out too much, which will directly reduce the brake spring pressure and reduce the braking force. The brake is not reliable when the machine is stopped, so the sliding distance exceeds the specified requirements. In this case, it is usually necessary to readjust the brake nut according to the lifting instruction.
If the problem is that the mini electric hoist brake ring is loose or damaged, and effective braking cannot be guaranteed, then the brake ring can only be replaced. If the brake ring is not damaged, but only a poor contact between the brake ring and the rear cover cone has occurred, resulting in a sliding distance exceeding the specified requirements. Then it is necessary to increase the braking force, find out the location of poor contact for repair grinding, increase the contact surface during braking, and replace the parts when it cannot be ground.
