Daily use of double column lifting machine

    

The double column lifting machine is frequently used, and its various parts may have some failures due to frequent load. If the failure is not solved in time, it will bring threat to our lives and property. What are some of the daily problems and how should we solve them,

In one case, the lifting machine has abnormal sound. It may be lifting overload

Solution: check the lifting weight. It may be that the fixing bolts of the motor are loose: tighten the bolts. There may be a lack of lubricating oil at the sliding block: add lubricating oil.

In the second case, the lifting machine can no longer lift. This may be due to the presence of air in the hydraulic oil. The solution is to loosen the exhaust screw and tighten it after exhausting the gas. There may also be a problem of hydraulic oil solidification.

Solution: drain the hydraulic oil and refill qualified hydraulic oil. The double column lifting machine may be caused by hydraulic oil leakage,

Solution: check whether the pipe fittings are tightened and whether the oil seal of the oil cylinder is deformed and warped. It may be the reverse rotation of the motor: check whether the wiring is correct by comparing with the circuit diagram in the motor. It may be that the motor does not rotate: the motor is broken, replace the motor fuse and the limit switch is broken, and replace the limit switch.

In the third case, there is oil leakage outside the lift. The problem may be that the connection of the lift is loose. The solution is to retighten the connection of pipe fittings. It may be that the exhaust valve at the top of the oil cylinder is loose. Solution: tighten the exhaust valve. It may be oil leakage at the seal of the oil cylinder. Solution: replace the sealing element. It may be the oil leakage from the vent hole. The solution: the internal seal of the hydraulic cylinder fails, and the seal shall be replaced. It may be that there is too much oil. Solution: the oil flows out of the container and the oil volume is appropriately reduced. The double column lifting machine is widely used in automobile maintenance and is an important automobile maintenance and repair machine. The product characteristics and quality of the lifting machine directly affect the personal safety of the maintenance personnel. Lifting machine plays an important role in automobile maintenance. I hope the brief introduction can help you. Thank you for your reading.
