Hydraulic freight elevator is a kind of machine equipment for direct transportation of goods in buildings with high stability and high working efficiency. Hydraulic freight elevator in the usual work, if there is no good care or irregular operation will appear some common problems, hydraulic freight elevator failure is characterized by the probability of failure and the use of time. The longer the application, the greater the probability of failure.

Here is a brief analysis of the hydraulic freight elevator work often encounter what problems:

1. Due to the internal and external influences of the distribution cabinet, excessive ripple index of switching power supply and excessive device load will also lead to unstable operation of hydraulic freight elevator.

2. The problems of the oil cylinder and its hydraulic power unit system are usually caused by insufficient driving force and unqualified quality of the oil cylinder, which also need to be paid attention to for the company itself.

3, the hoisting cargo transmission chain length is different, resulting in the table skew. It is proposed to contact the manufacturer to carry out dismantling and replacement. The probability of occurrence of such situation is low.

4. The slide rail link is misplaced, causing the platform to shake and sound in the process of lifting and lowering. After carefully check general hydraulic cargo lift installation ready to stringent inspection is used, caused many safety accident, hydraulic cargo lift in the installation phase, in view of the numerous small and medium-sized enterprises is not very care about this one phase, which is why have such amount of cargo lift equipment entities because of the problem.

5, there is a foreign body inside the delivery pipe, resulting in the transport of hydraulic oil support asymmetrical, will appear on the table asymmetrical status, it is proposed to carefully check whether the transport pipe is unobstructed.

6, the cylinder depletion is more serious, the inside of the closed ring damage is not symmetrical or there is a blockage is very easy to lead to the support is not symmetrical, resulting in the cylinder height is not symmetrical, carefully proposed oil cylinder is not all normal. No matter how it is caused by the loading fault must be dealt with immediately, otherwise it will turn from a small fault into a major safety accident, attach great importance to the cause of the fault, timely handling and solving the problem can greatly improve the application efficiency of the hydraulic freight elevator.
