The stacker is a wheeled carrier used for loading, unloading, stacking and short distance transportation of goods. It can be divided into semi electric stacker, electric stacker and manual hydraulic stacker. Among them, the electric stacker has been welcomed by enterprises in recent years because of its ultra-high working efficiency. However, no matter how advanced the machinery is, it is hard to avoid problems. What should be done if the electric stacker fails to lift? The electric stacker manufacturer tells you these methods.

If the electric stacker is unable to lift, it may be because the gear pump and pump lift are excessively worn; Oil pipe leaks; The hydraulic oil temperature is too high; Abnormal high pressure of relief valve in reversing valve; The lifting chain of the mast is jammed; The speed of oil pump motor is too low. Faced with these problems, the driver can take the following measures: replace the gear pump; Check and replace the hydraulic oil pipe; Replace the hydraulic oil and find out the cause of oil temperature rise; Remove the motor and check the fault. The electric stacker manufacturer reminded that in case the electric stacker is unable to lift, it is necessary to find out the cause in time and suit the remedy to the case.
If it is difficult for the gantry of the electric stacker to automatically tilt or jam, it may be because the tilt cylinder wall and seal ring are excessively worn; The internal spring of the reversing valve is damaged; The cylinder wall is stuck by the oil plug; Excessive bending of piston rod; There is too much dirt in the oil cylinder; The seal is installed too tightly. In this case, try to replace the seal ring, cylinder or spring. The electric stacker manufacturer reminded that the oil cylinder should be cleaned in time to avoid excessive internal dirt.

As a popular logistics transport vehicle, electric stacker has a huge advantage of convenient maintenance and repair. However, some minor failures are unavoidable. In case of problems such as the stacker cannot be lifted or the gantry is stuck, there is no need to worry. Check one by one according to the above methods and solve them in time, so that the work efficiency will not be affected. The electric stacker manufacturer recommends that drivers learn more about this kind of knowledge, which can save a lot of time when encountering problems.
