  & nbsp; Hydraulic elevator components are very important, and any problem can affect the operation and safety reliability of the elevator. If the elevator rises, what should we do? Perhaps many people do not understand. When the hydraulic elevator is overloaded, it will rise, mainly because each elevator has its own additional load. Once overloaded and lifted, it will show a phenomenon of weak lifting or rising. So a good approach at this point is to ensure that the goods are not overloaded.

  & nbsp; If the return valve of the equipment is not closed, it will not be able to rise. At this moment, the method of tightening the return valve can be chosen. When the manual pump check valve of the equipment gets stuck, the backflow problem will increase. The port can loosen the oil pump valve bolt to provide a solution for further protection, cleaning, and replacement of the cleaning hydraulic oil supply.

  & nbsp; The manual oil pump and gear pump of this device have severe oil leakage, which can be addressed by modifying the sealing ring of the oil pump. This may be due to equipment damage in the gear pump, but there is no lift pressure. A good solution is to replace the gear pump.

  & nbsp; When there is a shortage of hydraulic oil in the equipment, it will not rise or fall, and only needs to add sufficient hydraulic oil to operate. If the circuit of the device is disconnected and not improved, it is necessary to check the fuse for repair and replacement.
