What should I do if the manual hydraulic truck can bear the load but cannot be pressed high?

The principle of use of manual hydraulic trucks and hydraulic jacks is similar. They are lifted up by the force of the internal hydraulic cylinder. There are two large and small pistons at both ends of the oil cylinder. The force will be immediately transmitted to the large piston at the other end of the oil cylinder, and the large piston will then act on the handling steel plate, thereby smoothly pressing the heavy object up.

If the manual hydraulic truck can bear normal load but cannot be pressed high, it means that there is no problem with the load-bearing steel plate of the trolley. The source of this failure may be on its hydraulic device, which can be summarized as 4 reasons:

1. The hydraulic oil is less or there is no hydraulic oil; 2. The hydraulic oil inside the cylinder is of inferior quality and the purity is not enough; 3. Excessive tightening of the bolts or too tight screws will also make the hydraulic valve open; 4. The hydraulic cylinder Air was mixed inside.

To solve the above problems, we can start from four aspects: refueling, changing the oil, removing the air, and adjusting the bolts and screws.
