While mechanical system failures in elevators are relatively rare compared to other types of issues, they can still lead to significant consequences such as prolonged downtime, electrical malfunctions, or even serious equipment and personal safety incidents. Reducing the occurrence of mechanical failures is a key objective for maintenance professionals.

One common cause is poor lubrication or failure of the lubrication system. This can result in overheating, jamming, and damage to moving parts, forcing an unscheduled shutdown for repairs.

Another factor is the lack of regular inspections and maintenance. If wear and tear on transmission components, rolling or sliding parts are not identified and addressed in a timely manner, it can lead to more severe damage and ultimately force the elevator to stop for repairs.

Vibration during operation can also cause bolts to loosen, leading to misalignment and loss of precision. If these issues are not corrected promptly, they may result in grinding, collisions, or other mechanical failures that require immediate attention.

Additionally, if the elevator's balance coefficient is off from the standard, it can cause the elevator car to hit the top or bottom. When this happens, the speed limiter and safety gear will activate, stopping the elevator until repairs are completed.

Proper maintenance, regular checks, and attention to all mechanical components are essential to prevent these issues and ensure the safe and efficient operation of the elevator system.
