Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply,AjakshawScissor fork hydraulic lifting table, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.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.Ajakshaw,If any problems are found please contact the manufacturer in a timely manner to avoid exceeding the warranty period.. 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.Taranto,After hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.There are many reasons for unstable workbench descent such as overload, unstable support, severe eccentric load,AjakshawCustomized hydraulic lifting platform, hydraulic oil impurities etc. In response to the above reasons, it can be solved by reducing the load, adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.

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, 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.It is prohibited to work on unstable structures (such as asbestos tile roofs). To prevent accidental boarding, warning signs should be hung at necessary locations of this structure.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.Safety production,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.The elevator itself has a simple structure and is easy to maintain, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.Users should arrange dedicated personnel to operate hydraulic elevators, 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.High value,Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.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 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, and reduce shaking.Ajakshaw,Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use,AjakshawHydraulic lifting platform frame, it will cause leakage. Disassemble and clean the check valve, 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.Car mounted lifting platform: The car mounted lifting platform is designed to improve the mobility of the lifting platform by fixing it to a transport vehicle or truck. It receives power from the car engine and achieves the lifting function of the car mounted lifting platform. To adapt to high-altitude operations inside and outside the factory area.
