Today, we will introduce the reasons for the drop of the lifting arm of the hook arm garbage truck during use. The fundamental reason is that the cylinder itself has leaked due to a problem with the cylinder. The friend of the owner can check whether the seal of the vehicle is damaged. The internal leakage of the oil cylinder is basically caused by the damage of the oil seal, which causes the cylinder to fall.
There are other reasons that can cause the cylinder to fall:
First, the multi-way valve is faulty, and the hydraulic lock in the multi-way valve has a problem. The common reason is that the check valve spool is blocked or the spring fails, which causes the hydraulic lock to fail to act as a lock. The cause will fall.
Second, the hydraulic oil cylinder leaks oil. This is very easy to identify. Friends of the owner can check the hydraulic oil cylinders connected to the oil cylinders one by one to see if there are any leaks in the joints and the pipeline itself.
