The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.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.Xie Deze,Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, and odor. If necessary, the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, proportional control valve, overflow valve, etc. If there are problems, the hydraulic valve should be cleaned or replaced in a timely manner.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.ESPO, 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,Xie DezeHydraulic lifting platform lifting cargo elevator,Xie DezeHydraulic fixed lifting platform, 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, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. . The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels, buildings, airports, stations, sports venues, workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting advertising, etc.The installation personnel should have the qualification for installing hydraulic cargo elevators,Xie Deze8-meter hydraulic lifting platform, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.

Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.When the hydraulic cargo elevator needs to work, causing it to move upwards and lift heavy objects. The hydraulic cylinder moves downwards (i.e. the weight drops), the explosion-proof electromagnetic directional valve of the hydraulic oil enters the upper end of the hydraulic cylinder, and the return oil from the lower end of the hydraulic cylinder passes through the balance valve; Hydraulic control one-way valve; Throttle valve, and the workbench is evenly loaded to % of the maximum load capacity. After lifting times, each load-bearing component must not have deformation or cracks.Inspection requirements,After hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, there should be a device to make the workbench emergency descend.Quality inspection report,Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.The safety belt should be inspected before use and a static load test should be conducted regularly (every months). The load for the boarding bridge test is kilograms, and the test time is minutes. After the test, check for deformation, cracks, etc., and keep test records. Unqualified seat belts should be promptly dealt with.Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.Xie Deze,When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shakingThe manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.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, each load-bearing component must not have deformation or cracks.
