El SalvadorHydAfter 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.
The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, whether the internal and external emergency stop button switches the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
El Salvador.It is prohibited to work on unstable structures (such as asbestos tile roofs). To prevent accidental boarding, warning signs should be hung at necessary locations of this structure.
The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
.The hydraulic oil used in the system has the same brand,El SalvadorHydraulic lifting platform, and after each cleaning,El SalvadorHydraulic lifting table lifting, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.
The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil,El SalvadorChanging manual hydraulic lifting to electric hydraulic lifting, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve, and the relief time of the overflow valve is too short, it is easy to cause the pilot valve performance of the overflow valve to be partially stable, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn it should be replaced.
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.
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, 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.
How to maintain the cleanliness of hydraulic elevators. If more high-quality hydraulic oil is added, it can prevent oil changes or blockage of system components. However, these additives will lose their effectiveness after a period of time.
When the hydraulic system malfunctions, motor, valve and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.
High quality brand.Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
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.
The main device does not engage. When this fault occurs, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
Lines of various safety equipment
target.Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving, and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.
Lift and move horizontally with load to return to the loading position. For the transportation time of each item, replace the sealing ring. If there are debris or debris on the oil cylinder, it is recommended to replace it with a new one.
El Salvador.The undercut length of the weld mm should not exceed 10% of the weld seam, and the depth should not exceed 0.4mm.
The lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times each load-bearing component must not have deformation or cracks.
Remove the hydraulic oil tank filler cap, filter cover, inspection hole, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap, loosen the tank cap, and remove any remaining debris from the joint (do not rinse with water to prevent water from seeping into the tank). After confirming cleaning, open the tank cap.
