1, hydraulic valve. Mainly hydraulic lock problem, when the hydraulic check valve spool jamming or spring failure and other reasons, resulting in the hydraulic lock can not play a locking role, the cylinder will fall due to the load. In addition, there may be a reversing valve jamming, there is a load when the valve leakage caused by the cylinder fall.
2, the cylinder internal leakage. Cylinder has no bar cavity seal damage or sealing is not tight and other reasons, resulting in internal leakage of the cylinder and the fall is unknown.
3, pipeline oil leakage, due to pipeline or iron pipe oil leakage, will also lead to the automatic fall of the cylinder.
