Essentials of daily safety inspection and maintenance of lifts

一．Safety inspection of the lift

1. Before each use of the elevator, check whether the circuit is fully connected to prevent missing items, so as not to burn the pump station motor.

2. Check whether there are sundries on the outside of the elevator or objects that hinder the operation of the elevator.

3. Ensure that the hydraulic oil of the lift is filled up to avoid high temperature of the hydraulic station due to lack of oil.

4. Check whether the transmission system runs smoothly.

5. Run once without load before use, and observe whether the elevator is running smoothly.

二．Second, the maintenance points of the lift

1. Replace the hydraulic oil. Generally, after half a year of operation of the elevator, small particles will appear due to the friction of the oil cylinder. In order not to scratch the cylinder wall of the oil cylinder, new hydraulic oil needs to be replaced. The labels of the hydraulic oil are different, and the appropriate hydraulic oil model needs to be selected according to the local temperature.

2. Replacing the chain will cause very large wear during the use of the chain. Generally, the chain shaft must be replaced after it is worn to 10% of the original diameter.

3. Replace the wire rope. The wire rope is the second protection of the elevator, so the replacement of the wire rope is very important. It is recommended to check frequently to ensure the safety of the elevator.

4. Regular replacement of electrical components helps smooth operation. The aging of electrical components will affect the control system of the elevator and easily cause the elevator to be paralyzed.

The above is the daily safety inspection and maintenance of the lift. I hope everyone will strictly follow the above points for inspection and maintenance.
