Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, the new seal is too tight, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition,AboniLifting table hydraulic pressure, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.Aboni,What technical issues are required for the installation of hydraulic freight elevators? The installation of hydraulic freight elevators is actually quite complex. If you do not understand the equipment pictures designed by the elevator manufacturer and the detailed situation of the hydraulic freight elevator designed by the elevator manufacturer, installation errors may occur,AboniGuide rail hydraulic lifting platform, leading to equipment failure of the freight elevator! When installing hydraulic freight elevators, it is necessary to accurately calculate the size of the pit. The guide rail hydraulic freight elevator is a freight elevator composed of chains, guide rail torque tubes, and other components, mainly driven by the chain to assist in the upward and downward telescopic lifting of the freight elevator. The pulleys at the four corners of the countertop should be fixed on the surrounding guide rails. The entire elevator equipment is installed on the wall, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.Rosetta,What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork,AboniElectric hydraulic fixed lifting platform, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, and high safety.The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, hydraulic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.Users should arrange dedicated personnel to operate hydraulic elevators, and hang them on the

The undercut length of the weld mm should not exceed % of the weld seam, and the depth should not exceed .mm.When repairing the hydraulic system, only clean plastic plugs can be used to seal the end of the pipeline.Regularly check the operation of each mechanism for normal operation and noise. If any faults are found, the hydraulic cargo elevator wholesale should be promptly eliminated. Otherwise, it will affect the use of the guide rail hydraulic lifting platform. When refueling, the hydraulic oil should be filtered and filled, and the refueling tools should be reliable and clean. The hydraulic cargo elevator manufacturer should not remove the filter at the fuel tank filler to improve the refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.Installation material list,The vibration range is proportional to the lifting height. The higher the height the larger the shaking range, especially for mobile hydraulic cargo elevators. When the working height exceeds meters, the wind ropes at the four corners of the hydraulic cargo elevator should be tightened to strengthen leg protection, increase stability, and reduce shaking.When using hydraulic elevators, the main causes of noise are mechanical mechanism failures hydraulic system failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, 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.

Stability: The workbench should evenly withstand % of the MAX load capacity and be stable at the MAX elevation.Promotion,Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB-.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.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.Aboni,Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)Each brush should be kept clean on its surface, 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 shaking
