The reason why the mobile hydraulic lift does not rise to the rated height

by:Powerston     2021-05-25
The mobile hydraulic construction lift has been used for a long time, and it often fails to reach the rated height during the ascent process. What is the cause of this? How to solve it? The elevator manufacturers will answer for you one by one: (1) Check whether the motor is working normally, because the motor coil is damaged, there will be 'false operation(2) Check whether the fuel tank has bad sealing. If the maximum height cannot be reached, check the fuel tank, as this will cause insufficient pressure, power drop, and inability to ascend to the maximum height. (3) Check whether the hydraulic oil is in good performance. The hydraulic oil should be replaced once a year. The wear resistance and pressure resistance of the hydraulic oil are severely reduced, which will cause the pressure to drop and the lifting cage height cannot reach the standard. (4) Check whether there is a problem with the power system. Whether the diesel engine or the power starting system meets the required standards for lifting, the equipment will be damaged due to the failure of the conditions. (5) Check whether there are foreign objects obstructing the key parts of the support arm. We must pay attention to the cleanliness of the key parts. (6) Check whether the limit switch is malfunctioning. The limit switch will run automatically when the lifting cage platform reaches the rated height. At this time, check whether the operating state is advanced. (7) Check whether the oil cylinder is faulty. The oil cylinder is the main executor of the electric lifting platform. When the equipment is running, check whether the oil cylinder can reach the standard stroke. (8) Check whether it is overloaded and unload it in time. Overloading will shorten the service life of the equipment and affect normal lifting.
