& nbsp; The mechanical system of elevators accounts for a relatively small proportion of all elevator malfunctions, but once a malfunction occurs, it may result in long-term downtime for repair or electrical problems, and even serious equipment and personal accidents. Further reducing the mechanical system problems of elevators is the policy that repair personnel strive to achieve. Due to poor smoothness or problems with the smooth system, the transmission parts of the components may overheat, burn, and get stuck on the shaft, causing damage to rolling or sliding parts and forcing the machine to stop for repair.

  & nbsp; Due to the lack of daily maintenance and inspection, the wear level and condition of the relevant components in the transmission, rolling, and sliding parts of the components were not detected in a timely manner, and the correct correction was not made based on the wear level of each component, resulting in component damage and forced shutdown for repair.

  & nbsp; Due to the oscillation of the elevator during operation, the fastening bolts become loose, causing displacement of the components and loss of their original accuracy, which cannot be corrected in a timely manner, resulting in wear, collision, and damage to the parts and forcing them to stop repairing. Due to the significant difference between the elevator balance coefficient and the specifications, an overloaded elevator car may squat or crash, causing the speed limiter and safety gear to actuate during the crash and forcing the elevator to stop running, waiting for repairs.
