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, insufficient power supply,Washington DCHydraulic lifting platform, 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.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.Washington DC,The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.The guide rail type elevator has a structure of a straight top oil cylinder. The linear operation of the oil cylinder pulls the transmission chain, driving the lifting of the table to complete the operation. The guide rail type elevator is a popular form of cargo elevator in recent years with the advantages of higher lifting height, stable operation,Lines of various safety equipmentI believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.After hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.

For hydraulic cylinders in hydraulic elevators, 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.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.Regularly check the operation of each mechanism for normal operation and noise. If any faults are found, the hydraulic cargo elevator wholesale should be promptly eliminated. Otherwise, it will affect the use of the guide rail hydraulic lifting platform. When refueling, the hydraulic oil should be filtered and filled, and the refueling tools should be reliable and clean. The hydraulic cargo elevator manufacturer should not remove the filter at the fuel tank filler to improve the refueling speed. Refueling personnel should use clean gloves and work clothes to prevent solid and fiber impurities from falling into the oil.Quality assurance,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 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, increase stability, and reduce shaking.When the hydraulic lifting platform is working, the larger the mass of the object,Reason: Cleaning method for internal leakage in the oil cylinder: Replace the sealing element of the oil cylinder. The lifting platform does not lower. Reason: The lowering valve is malfunctioning. Cleaning method: When pressing the lowering button, clean it as much as possible; If there is power, clear the malfunction of the lowering valve itself or replace the lowering valve. The sliding valve should be kept clean and.The manufacturer of hydraulic cargo elevators tells you the precautions for high-altitude operations.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.Washington DC,The above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators,Washington DCManual pressure relief of hydraulic lifting platform, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.. 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,Washington DCFreight elevator type hydraulic lifting platform, 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 the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking
