Daily maintenance and common faults of lifting columns

Routine maintenance

1. Avoid continuous rise or fall during use. Rise and fall should not be switched quickly and continuously, which will easily shorten the service life of the motor and hydraulic pump.

2. Check the oil level in the fuel tank regularly. If the oil level is lower than the bottom line, you need to add oil. If the oil color becomes dark and turbid, you need to consider replacing the oil.

3. It is strictly forbidden to raise if there is a vehicle or pedestrian above the road pile to avoid danger.

4. Keep the bottom of the pile on the hoistway clear and clean around, to ensure the service life and performance of the lifting pile parts and waterproof sealing.

5. On large ice and snow days, if there is severe icing inside the column, lifting is prohibited. It can be used after thawing by heating.

common problem

Hand pressing the control panel button has no action

Causes: 1. The power supply line is faulty.

2, the fuse is blown

3, motor failure

Processing method: 1. Check if the AC220V power supply is normal.

2, replace the same type of fuse

3. Replace the starting capacitor or repair the motor

The column cannot rise or rise very slowly

Reasons: 1. The oil supply system is not smooth.

2. The pressure relief valve is not closed tightly.

3, overflow cutting over pine

Treatment method: 1. Check the oil pipe to ensure that it does not gamble.

2, close the pressure relief valve

3, fine-tuning the relief valve

The cylinder drops very slowly:

Reasons: 1. The oil supply system is not smooth.

2. The relief valve is too tight or too loose

Treatment method: 1. Check the oil pipe to ensure that it does not gamble.

2, fine-tuning the relief valve

The cylinder has a straight drop

Reasons: 1. Manual pressure relief valve is too loose

2, hydraulic oil leakage

3, hydraulic lock failure

Treatment method: 1. Close the pressure relief valve

2, eliminate leakage, add hydraulic oil

3, replace the hydraulic lock
