How is the work of Shanghai Mitsubishi Elevator?

Judging from the simple work at present (responsible for the regular maintenance and inspection of elevators), this work is not bad.

Whether it is suitable or not depends on salary, benefits and development space. All work is a process of mutual choice. This job needs a strong sense of responsibility, and it will be hard. After all, the daily maintenance and inspection of elevators are closely related to the safety of residents' elevator travelers. If you are careless and lazy, it is not appropriate.

Detailed work contents of elevator maintenance:

1, lubrication

Traction wire rope is a very important part in elevator. It is a device that provides suspension for the elevator and bears all the weight of the elevator and passengers. The elevator car is also driven by the friction of the traction wire rope on the wheel groove. Therefore, once the traction wire rope is damaged, it will be related to the safety of people's lives and property, and it needs regular inspection and lubrication maintenance.

2, nondestructive testing

Once the wire rope is put into use, its performance and service life will gradually decrease, so it must be inspected regularly and monitored in real time according to the regulations, which is mainly divided into two parts: external inspection and internal inspection.

External inspection can monitor whether there are defects such as corrosion, deformation and excessive broken wires on the surface, and internal damage can be realized by ray inspection, acoustic inspection, mechanical inspection, ultrasonic inspection, eddy current inspection, vibration inspection and other technologies.

3, steel wire lubrication

Wire ropes need to be lubricated and cleaned regularly to ensure a short service life. In particular, the surface of traction wire rope often accumulates a layer of oil stains, which is caused by the mixture of lubricating oil and dust. If it is not removed, it will affect the service life, change the friction coefficient and reduce the traction capacity. Steel wire lubrication also has anti-corrosion effect, which can reduce wear and tear.

4. Mechanical part

Elevator traction machine, elevator car guide shoes, elevator hall doors, elevator car doors and other mechanical parts also need to be well maintained and cleaned, which are related to the use of elevators.
