The Application and Troubleshooting of Pallet Jack

The manual hydraulic truck is a small, convenient, flexible, heavy-duty, durable cargo handling tool. In addition to the function of consigning goods, the truck has hydraulic equipment for the convenience of taking off and landing. It can easily push the car under the base of the cargo box, then raise with hydraulic pressure and lift it up, then goods can be dragged to move. After reaching the destination, the goods can be landed, the truck can be conveniently taken out.  It is a good helper to handle the goods in working process.

Precautions
Routine inspections every day, eliminate abnormal phenomena in time. If there is any fault, ask a professional to troubleshoot, and need to replace the parts, the parts should be provided by the manufacturer. Each rotating joint adds motor oil once every three months, paying special attention to the wheels and shafts to ensure that they are not entangled by debris, keeping all the wheels rotating and meet the safety requirements.

Troubleshooting
This pallet truck often has  problems, such as slow rise and slow decline, or simply can't rise. When it can't rise, people always think that it is broken? In fact, this is not a case. There is only air in the oil pump, which causes the hydraulic pressure to not rise or rise slowly! At this time, it is only need to vent the air to make the manual truck intact.

The method of venting air is simple:
Manual trucks usually have three gear positions

1. In the middle is the positioning gear, which does not rise or fall.

2. The up button is the neutral gear, that is, the lowered gear position and the pressure relief gear position.

3. The downward dial is the hanging gear, that is, the oil seal can be closed to allow the hydraulic pressure to rise.

We only need to push the gear up, and then press the handle a few times as usual. At this time, although the car body does not rise, it can effectively remove the air inside the pump. After about 10-20 times, the air can be drained.
