Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.Regularly inspect the hydraulic lifting equipment of the upper and lower materials to ensure the safety of the rail type elevator and the safety of the material supply to the rail type lifting platform.Pabiannis,When working simultaneously at the upper and lower levels, a tight and firm protective partition, canopy or other isolation facilities must be erected in the middle of the boarding bridge, and workers must wear safety helmets.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.Rocafuerte,The hydraulic oil used in the system has the same brand, and the oil temperature is between ~ ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, 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 characteristics of the platform include reliable hydraulic system, large load-bearing capacity,PabiannisHydraulic guide rail type lifting platform, and rear hinge support.Therefore, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.

. 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. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents, a hydraulic one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.Stable and widely applicable cargo lifting equipment is mainly used for transporting goods between height differences in production lines; Material online and offline; Adjust the height of the workpiece during assembly; High altitude feeder feeding; Lifting of components during assembly of large equipment; Large machine material and cutting; The warehouse loading and unloading site is equipped with forklift and other transportation vehicles for rapid loading and unloading of goods.investment, confirm that there are no omissions in the shipped equipment details, check if the tools are complete, and ensure the smooth progress of the installation process.The noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, Mixing air into the oil to eliminate: The concentricity should be adjusted to within .MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, filter the oil, lock the return oil pipeline, it will cause cavitation under high pressure and cause significant noise. At this point it is necessary to exhaust the air in a timely manner.When the hydraulic lifting platform is working, the larger the mass of the object the load cannot exceed its rated load. When it is raised to a certain height, the greater the shaking

To consider its capacity, generally mobile equipment takes - times the high flow rate of pump Z, and fixed equipment takes - times.Discount,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.Clean the surface of the base and install anchor bolts. If the construction elevator is installed on the floor, use a pad iron under the base screws to increase the force surface between the nut and the floor, in order to reduce the impact of the nut on the floor; Insert steel plate gaskets of different thicknesses between the chassis and the foundation stone at the anchor bolts to adjust the verticality of the guide rail frame; Install three standard sections and measure the verticality of the guide rail frame using a theodolite; After adjusting the verticality of the guide rail frame, tighten the four foundation bolts; Adjust the verticality of the fence door frame as above and press it tightlyThe 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,PabiannisSelf propelled hydraulic lifting platform, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.Pabiannis,The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.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.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.
