Many unexpected accidents are inevitable when using lifts, so in order to reduce the probability of safety accidents, we still need to take measures in advance to prevent these common faults. So, how should we operate specifically?

The working principle of hydraulic lift: The main driving method of hydraulic lift is to drive hydraulic oil through the pump station, and the hydraulic oil drives the oil cylinder to rise to reach the set height. To avoid the occurrence of hydraulic lift failures, we should first check what caused our equipment.

The general fault analysis is as follows:

1. If the lift falls by itself, the first thing that is certain is the return of hydraulic oil. Generally, it is due to the loose closure of the shut-off valve or oil leakage in the oil pipe. We can determine which situation it is based on the amplitude of the elevator's descent.

2. If it is a hydraulic lift leaking oil, we should consider whether the oil pipe joint is loose or the sealing ring is damaged, and further diagnosis needs to be made based on actual situations or usage experience.

3.If the lift platform cannot lift or the lifting power is not provided, we need to make a comprehensive judgment. There are also many reasons for this, which can be considered from the following aspects:

• Power failure is the simplest and easiest mistake to ignore, so we should operate carefully.
• Is the return oil valve tightly closed? Check if the return oil valve is closed. If the return oil valve is not closed, the pump station cannot deliver hydraulic oil to the cylinder, causing the motor to idle. This situation not only causes the elevator to not rise, but also burns out the motor. Therefore, we should avoid this low-level error from happening.
• Whether to overload or not, we need to consider whether overloading can cause significant damage to the lift or prevent it from rising. Generally, we install overload protection for lift equipment to further protect the lift from damage caused by overload.

These are some mechanical failures that we may frequently encounter when using hydraulic lifts. You can refer to the contents listed above for reference in the future.
