The failure of the spring of the electric stacker may cause the gantry to be skewed or unbalanced, etc.

The electric stacker plays a great role in handling and stacking goods, which greatly reduces human resources and improves the efficiency of operations. Today's stacker trucks no longer use diesel as raw material, and use more environmentally friendly and clean electric energy, which makes the operating environment better. With the advancement of technology, the current stacker trucks use an integrated operating system, which greatly reduces the difficulty of use. The safety protection system is also very well done, and the speed is freely controllable. The lightweight body makes them suitable for more However, there will inevitably be some small problems in the process of use. What are the common problems? How should we maintain them?

1. The stacker gantry is skewed or unbalanced

1. p>

The reasons for the difficulty in actively tilting the stacker gantry or the inability of the movement to flow include the failure of the valve stem spring in the reversing valve; excessive wear on the wall of the tilting cylinder and the sealing ring; too much dirt in the tilting cylinder or too much seals Compression; piston stuck to cylinder wall or piston rod bent. The solution is that the spring should be replaced with a new one immediately if the spring fails.

2. Seal ring wear

If the seal ring is severely worn, it should be replaced immediately. If the oil cylinder is also severely worn, the oil cylinder needs to be replaced; the dirt in the oil cylinder should be cleaned and cleaned. As for the seals If it is too tight, it can be adjusted. If the wearing parts of the piston are damaged, they should be replaced immediately. The oil pump pressure is insufficient, and the lifting speed is obviously slowed down: the oil pump pressure is insufficient or the speed is too slow because the sealing ring in the pump cover groove is damaged or the gear is severely worn. .

3. The speed of the oil pump motor drops and there are foreign objects in the pipeline.

Treat these faults and replace the damaged sealing ring or gear. If the speed of the oil pump motor decreases, the position of the carbon brush may be incorrect or it may be carbon deposition between the sheets, so it is only necessary to clear or adjust the position of the carbon brush; if the foreign body is blocked, just clean it.

4. The circuit is not running normally

The circuit may be running abnormally because the micro switch in the electrical box is damaged or the position is not adjusted properly. This only needs to replace the micro switch and re-adjust the position; if the main circuit fuse or the control electrical fuse is blown, just replace the fuse of the same type; if the battery voltage is too low, it can be recharged; if it is a contactor Contact singeing or too much dirt can cause poor contact to repair the contact, adjust or replace the contactor; if the contact does not move, it may be that the contactor coil is open and should be checked and dealt with immediately, or the contactor may be replaced.

While enjoying the convenience brought by the electric stacker, the daily maintenance should not be forgotten. After use, it should be parked in a suitable location, and it is also regularly repaired, which not only can Extending the service life of the stacker is also responsible for its own safety and ensuring smooth use. The operator should also check the brakes, power supply, body, etc. before use, and repair them in time if there are any problems.
