Considering the oil level in the oil tank when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, the oil level should not be higher than the Z-high oil level. In fact, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted,NiorHydraulic cylinder lifting platform, and if the adjustment is ineffective, replace it with a new valve.Nior,Hydraulic cargo elevator sinking refers to the lifting of the cargo elevator equipment to a designated position, and after a period of time, the entire table surface will automatically descend by a certain distance under its own weight. The phenomenon of hydraulic cargo elevators naturally descending during the leveling process. This phenomenon is definitelyTherefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.Zaihran, There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, overload is the root cause of many faults.The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.

The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years with the advantages of higher lifting height, and simple maintenance compared to the scissor fork type elevator.The hook or rope of the seat belt should be hung on a sturdy and sturdy component or a steel wire rope specifically designed for hanging the seat belt. Prohibit hanging on moving or unstable objects.When the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.Installation material listBefore installation, pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.

The cylinder head oil seal is too tight or the rod is bent, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.Total quality management,The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness,NiorMobile hydraulic lifting platform/lifting platform, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.The hydraulic system of the fixed lifting platform of the hydraulic cargo elevator is equipped with anti fall and overload safety protection devices, and operation buttons can be set on each floor and the lifting platform workbench to achieve multi-point operation.Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.Nior,NiorHydraulic lifting platform lifting cargo elevator,Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.When using an electric mobile scissor lifting platform outdoors, if the wind force exceeds level , please stop using it; When the lifting height exceeds meters, the wind ropes at the four corners of the hydraulic lift platform should be tightened and fixed, and the support legs should be reinforced for protection and stability to avoid safety accidents caused by excessive swinging of the electric lifting platformDue to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
