How to deal with several common faults of manual stackers?

The most common faults of manual stackers are that the forks cannot be driven and the oil cylinder leaks. This is the most common failure and the one we deal with the most. If the forks of the manual stacker cannot be struck, let's analyze the main reasons for the failure and some troubleshooting methods.

In the first case, the fork frame of the manual stacker cannot reach the maximum height. The reason for this is insufficient hydraulic oil. The solution is to add hydraulic oil;

In the second case, the fork of the manual hydraulic stacker cannot be lifted. There are four possibilities:

1. There may be no hydraulic oil, this only needs to be refueled;

2. The hydraulic oil may be impure, release all the hydraulic oil in the cylinder, and re- Replace the hydraulic oil;

3. It may be that the adjusting nut is too high. Open the unloading valve to increase the test pressure of the adjusting adjusting nut.

4. It may be that there is air in the hydraulic oil. . It is sufficient to remove air from the hydraulic oil. The exhaust method is to pull the finger handle to the lower position, and then pull the handle up and down several times.

The fork of the manual stacker cannot be lowered:

1. The piston rod or cylinder body is damaged and deformed due to the deviation of the goods to one side or overload, replace it The piston rod or cylinder block is enough;

Secondly, it may be that the fork frame of the manual stacker is in the raised position for a long time, and the piston rod is exposed and rusted, so that the piston cannot move. The solution is to lower the fork carriage of the manual stacker when not in use. To the lowest position, pay attention to lubricating the piston rod in time;

Third, the adjustment nut may be in the wrong position. The solution is to adjust the nut.

There are also some common failures, such as aging or damaged seals in the manual stacker, and oil leakage due to damage to certain parts. The solution is to replace the seals and parts.
