The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, safety contact bars to prevent foot rolling, organ type safety protective covers, manual or motorized rotating workbenches, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, and universal ball countertops.Ketai,In case of strong wind of level or above, thunder, fog and other bad weather, the work at heights in the open air shall be stopped at the boarding bridge.The optional configurations of a fixed lifting platform include manual hydraulic power, movable flip plates that are easy to overlap with surrounding facilities, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, organ type safety protective covers, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, and universal ball countertops.Toreviyeha,Materials enter the production line at one end of the factory building, and the production process ends at the other end of the factory building with multiple separate platforms; This can greatly shorten the distance of material flow in the factory building.The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil,KetaiIndoor fixed hydraulic lifting platform, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within .MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to % of the maximum load capacity. After lifting times,KetaiHydraulic aluminum alloy lifting platform, each load-bearing component must not have deformation or cracks.

Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder, it is recommended to replace it with a new one.Usage and instructions for steel wire ropes in elevators: The steel wire ropes of the steel wire ropes require very high strength, usually made of high-quality carbon steel with a carbon content of .% -.%. They are widely used as transmission components in elevators. Due to its large load-bearing capacity, light weight, smooth operation, no noise, suitable for high-speed transmission high strength, strong overload capacity, and reliable operation,Ketai12 meter hydraulic lifting platform, it has become a commonly used rope for hydraulic elevators.There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.total cost,When the hydraulic system malfunctions the hydraulic elevator may experience problems with the hydraulic pump, motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.The use of cleaning oil and the brand used in the systemWhen using hydraulic elevators, frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator, but also enables it to exert greater power during operation. Of course, hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).

After hours of elevator operation, perform minor repairs to the mechanical and electrical systems.Total quality management,The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.Due to the formation of a flow closed-loop, the volumetric speed regulation hydraulic elevator has good performance and high load stiffness. The hydraulic system using the volumetric speed regulation scheme has a higher efficiency and greater energy loss compared to the throttling scheme, as its output power is roughly equal to the power required for the elevator to move up. But using an elevator volume speed control system can only reduce the energy consumption during the upward process of the elevator. When the elevator goes down, the oil in the cylinder moves down the throttle valve under pressure, which will cause the temperature of the hydraulic system to rise. Not to mention anything else, just an intelligent alarm is enough to demonstrate the true value of hydraulic elevators.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.KetaiWhen 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 platformLines of various safety equipmentAfter long-term use of the automatic lifting platform equipment, it is inevitable that some malfunctions will occur. In order not to affect work, it is necessary to promptly solve the difficulties in starting the motor and abnormal sounds. Generally, due to overload, insufficient power supply, and a small cross-sectional area of the power supply cable
