The failure of the elevator mechanical system accounts for a small proportion of all elevator failures, but in the event of a failure, it may cause long-term shutdown or electrical failure or even serious equipment and personal accidents. Further reducing the failure of the elevator mechanical system is a goal that maintenance personnel strive to achieve.

1Because of poor lubrication or failure of the lubrication system, the parts of the transmission part will be burned and hung, and the parts of the rolling or sliding parts will be damaged and forced to be shut down for repair.

2Because there is no routine inspection and maintenance, the wear and tear of the parts in the transmission, rolling and sliding parts of the parts are not checked in time, and the wear and tear of the parts are not properly repaired, resulting in damage to the parts. Forced to stop repairs.

3Because the vibration of the elevator during the running process causes the fastening bolts to loosen, the parts are displaced, the original precision is lost, and the repair cannot be repaired in time, causing the grinding, bumping and crashing parts to be stopped.

4 Because the elevator balance coefficient is too far from the standard, the overloaded elevator car is bottomed or topped. When the top is over, the speed limiter and the safety gear act to force the elevator to stop running and wait for repair.
