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.Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch,NicastroIndoor fixed hydraulic lifting platform, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.Nicastro,In winter, when working outdoors at heights below minus degrees Celsius, heating rest areas should be set up near the construction area if necessary. Heating equipment should be managed by dedicated personnel and attention should be paid to fire prevention.A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.Kyenjojo,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, 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.The elevator is evenly distributed at any position on the guide rail at % of the maximum load capacity, and should be stable at the maximum lifting height.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, 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.

The hydraulic lifting platform is a manually movable type, and the lifting power of the platform is a two machine or three-phase power supply. It has manual and electric power, stable lifting, and easy operation,NicastroSmall hydraulic lifting platform, and are mainly used in factories, commercial stores, and the construction and decoration industry.The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.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-.ranking,Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner. Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of meters, if possible, please use safety protection measuresThe lifting platform is placed on a horizontal support surface, and the concentrated load of MAX load capacity is placed at any position mm away from the periphery of the workbench. After lifting times, each load-bearing component must not have deformation or cracks.

When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.Quality inspection report, 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, 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.In on-site hydraulic elevators, it is difficult to detect the rising position, middle position impact noise, and oil film leakage of hydraulic cylinders. Field observations have shown that the excessive lifting speed of the hydraulic cylinder has led to an increase in failure rate,Nicastro8-meter hydraulic lifting platform, seriously affecting production efficiency. The unstable hydraulic lifting requires an analysis of the hydraulic oil flow rate. Hydraulic pressing oil has poor quality and contains a large amount of impurities, which can also prevent slow and unstable lifting. In addition, there are other reasons: lifting the composition of the hydraulic ring. Oil pump, safety valve, directional valve, directional valve, one-way throttle valve (without throttling), and lifting cylinder. 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, 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.Nicastro,Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, becoming a better choice for some high-altitude operations. However there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.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.Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use, it will cause leakage. Disassemble and clean the check valve, and replace it if necessary.
