What are the hydraulic failures of the manual hydraulic transporter
The main performance is that the hydraulic vehicle can not rise or the lifting speed is slow, and even there may be automatic landing. All these will give you the illusion of whether the hydraulic vehicle is broken, but don't worry at this time. Try to operate the following points, which may save a lot of maintenance costs.
First, check the cylinder oil. The first is that there is not enough oil. Just like we drive, enough oil can make the machine run normally. Therefore, before using the machine, make sure that the oil cylinder is filled with oil; In the second case, the purity of the oil is not enough, which will lead to failure to press. Here, it is necessary to replace the pure hydraulic oil in time.
Secondly, check the pressure valve. If the joint bolt is too close or the adjusting screw is too tight, and the valve is always open, the carrier may not be able to press up. Just close the check valve here.
