Escalator maintenance

The maintenance of escalators is an important link to ensure their safe and reliable operation. The following are some basic points for escalator maintenance:

Regular inspection:

Check the operating status of the escalator daily to ensure there are no abnormal phenomena such as abnormal noise and vibration.

Regularly check whether the safety devices of the escalator, such as emergency stop buttons and photoelectric protection devices, are normal.

Cleaning and maintenance:

Regularly clean the steps and handrails of the escalator to prevent the accumulation of dirt and debris.

Clean the surrounding environment of the escalator to ensure that there are no obstacles affecting the operation of the escalator.

Lubrication maintenance:

Regularly lubricate the moving parts of the escalator to ensure its smooth operation.

Check and replace lubricating oil to prevent wear due to lack of oil.

Inspection of electrical system:

Regularly check the electrical circuits and control systems to ensure there are no short circuits or leakage phenomena.

Check the operating status of equipment such as motors and frequency converters.

Inspection of mechanical parts:

Regularly check the wear conditions of mechanical parts such as chains, gears, and bearings.

Ensure that all bolts and connectors are tightened to prevent loosening.

Safety inspection:

Regularly conduct safety performance tests to ensure that the escalator complies with relevant safety standards.

Check whether the warning signs and instructions for use of the escalator are intact.

Record maintenance:

Maintenance work should have detailed records, including inspection dates, contents, discovered problems and treatment measures.

Professional maintenance:

It is recommended to regularly invite professionals to conduct comprehensive inspections and maintenance, especially for escalators that are frequently used or old.

Regular maintenance can effectively extend the service life of escalators and ensure the safety of passengers.
