The reason analysis and solution of five common mechanical failures of manual hydraulic transport vehicles

Manual hydraulic transport car oil spills

Cause analysis: the majority of the situation is the seal parts damaged, spare parts wear or crack

How to solve: to replace the new, wear-resistant seals, check the problem of spare parts to find a professional repair or replace the new

Two, manual hydraulic lift truck lift not up to the highest position

Reason analysis: hydraulic oil shortage, resulting in the rise of the time, the power of the oil valve can not reach

How to solve: check oil quantity and re join the new hydraulic oil

Three, manual hydraulic handling truck fork automatic descent

Reason analysis: the hydraulic oil into the air, or there is debris, the pressure relief valve is too loose,

Discharge air, clean up the debris, adjust the pressure relief valve to the appropriate location

Four, manual hydraulic truck truck can not fall

Cause analysis: the pressure regulating valve of the hydraulic system on too tight, or because of overload on the rise causes the piston rod deformation,

How to solve: check and adjust the pressure relief valve, replace a new piston rod (do not overweight again rise)

Five, manual hydraulic handling truck fork lift not up

Cause analysis:

(1) the hydraulic cylinder pressure is very low, it is difficult to reach the load

How to solve: check and adjust the pressure relief valve.

(2) there is air inside the cylinder, to bring the instability of the cylinder

How to solve: the inside of the air out

(3) the relief valve is in the open state, leading to the hydraulic oil into the cylinder.

How to solve: check the relief valve there is no debris, clean up and adjust the relief valve to the normal

(4) the contact side of cylinder head and piston is very close, so that the hydraulic oil cannot go in, not strong thrust for cylinder operation

If the above methods can not solve the problem of hydraulic manual handling car, can directly contact the manufacturer - Jiangsu Jingxin hoisting machinery maintenance
