The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.The combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.Almero,The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.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)Shandi,Regularly check whether each organization is functioning properly and whether there is noise. If problems are found, they should be promptly cleaned up.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.The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.

Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.When working on the dam crest, steep slopes, roofs, cliffs, towers, suspension bridges, and other dangerous edges safety nets or protective railings should be installed on the side facing the air. Otherwise, workers must use safety belts. Ice, snow, gravel and soil on the steep slopes of steep cliffs, boarding bridges or sidewalks must be regularly cleaned, and a -meter high railing must be installed on the outer side. Install an centimeter high side board or soil ridge on the inner side of the railing to prevent falling objects from injuring people.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, 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, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, 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.knowledge,Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.To consider its capacity, generally mobile equipment takes - times the high flow rate of pump Z, and fixed equipment takes - times.The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump,AlmeroHydraulic lifting platform and hydraulic lifting platform, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.

Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.Supply chain quality management,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.When working at heights, except for relevant personnel, no one is allowed to walk or stay below the workplace. Fencing or other protective devices should be installed below the workplace to prevent falling objects from injuring people.The hydraulic pump produces noise. When the hydraulic elevator rises, which causes periodic changes in the hydraulic system pressure, it will also cause resonance in the hydraulic system and generate noise.Almero,The development of elevators is at its peak, so they also need a device to facilitate the improvement of goods.Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on theThe cylinder head oil seal is too tight or the rod is bent,AlmeroCustomized hydraulic lifting platform, which can also cause noise during movement due to other forces. At this point, the oil seal or straightening rod must be replaced in a timely manner.
