When the hydraulic system of the truck crane is under-pressured or has no pressure at all, the operating speed is slow or the lifting is weak. The operator of the truck-mounted crane should stop the operation immediately and resume the operation after troubleshooting. CLVEHICLES.COM crane truck inform you how to eliminate various methods of insufficient pressure in the truck crane hydraulic system.
1. See if the hydraulic pump can output hydraulic oil. If there is no hydraulic oil output, it may be: the steering of the pump is not correct; the parts are severely worn or damaged; the resistance of the oil suction pipe is too large (the oil filter is clogged, the oil viscosity is too high, etc.) or air leakage.
Remedy: Disassemble and clean the overflow valve; check or replace the spring to restore its working performance.
2. See if the entire hydraulic system can build up normal pressure. There is no pressure in some pipelines or hydraulic cylinders (hydraulic motors), which may also be caused by blockage of pipelines, throttle valves, reversing valves and other components.
Remedy: Check the pressure and whether there is oil passing through section by section, find out the reason, and eliminate it.
3. See if the overflow valve is working properly. If it is not normal, it may be that a valve in the pressure oil circuit has dirt or other reasons and is stuck in the oil return position, causing the pressure oil circuit to communicate with the overflow circuit. It may also be that the oil pipe joint is loose, or some valves in the pressure oil circuit are leaking seriously, or the seals of the hydraulic cylinder and hydraulic motor are damaged, causing serious leakage.
Remedy: Disassemble the relevant valve for cleaning, check the size of the sealing gap and various sealing devices. If the sealing device is damaged, it should be replaced.
