Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.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.Ulm,Cleaning and maintenance: When there is oil in the oil tank or when oil is refilled, it is necessary to ensure the cleanliness of the filter tank cover. Clean the oil and funnel or container before use. Never bring dirty things into the system, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.Wurize,After 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, and a small cross-sectional area of the power supply cable, the starting voltage drop is too large and the price of the cargo elevator is reduced.The hydraulic pump produces noise. When the hydraulic elevator rises, the hydraulic pump runs at high speed. If there is a problem with the gears or bearings of the hydraulic pump, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.Stability: The workbench should evenly withstand % of the MAX load capacity and be stable at the MAX elevation.

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.Therefore, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited amount of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.The manufacturer of hydraulic cargo elevators will tell you about the knowledge of specialized lifting platforms for unloading.discount,After hours of operation on the hydraulic lift, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally, the speed can only be adjusted by changing the flow rate. For variable displacement motors, speed regulation can change both the flow rate and the motor displacement.When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear and its meshing surface is not less than %. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.

If the circuit of the device is not disconnected or lowered,UlmFixed hydraulic elevator, it is necessary to check the fuse for repair and replacement.Quality inspection report,Do you know the classification of simple cargo elevator lifting platforms? The manufacturer of the hydraulic cargo elevator is here to inform you.Any work carried out at a height of meters or above should be considered as work at height. Any work that can be done in advance on the ground must be done on the ground to minimize high-altitude operations.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,UlmElectric lifting platform Hydraulic lifting platform, 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, 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.Ulm,Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve,UlmHydraulic lifting platform frame, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
