In our daily operation, there may be various problems in the process of using the lifting platform. Some customers said that the platform does not rise when using the hydraulic lift. In response to this situation, today Jinan Huagong lifting platform manufacturer will give you a summary A few possible reasons:

1. The voltage is too low

Check the starter potential when the motor load is operating. Usually the voltage floating range allows ±10%.

2. The motor does not turn

Check whether the motor and circuit are connected properly.

3. Motor reverse

Arbitrarily change two phases of the three-phase line.

4. The motor is out of phase (the motor does not move, and there is a humming sound)

Check circuit breaker and motor wiring.

5. The drop valve is open

When the lowering button is released, use a voltmeter to check whether the lowering valve has electricity. If there is no electricity, check the circuit and troubleshoot; if there is electricity, troubleshoot the drop valve itself. The spool of the drop valve must be kept clean and flexible.

6. Low pressure of relief valve

Readjust the relief valve. Adjust at 100% rated load.

7. The oil level is too low, the oil pump sucks empty

Top up the hydraulic oil.

8. The oil suction filter is blocked

When cleaning the filter, keep the filter unobstructed at all times.

9. Air leakage in the oil suction section

Check suction pipe and fittings; tighten fittings. Replace the connector if necessary.
