Now auto 4 s shops, garage, car hairdressing, mechanics school, etc., are equipped with scissors lifting machine, gantry lifting machine, four-column, etc all kinds of lifting machines, lifting machine in the process of using or want to know how to maintain the common sense of the lifting machine, to prevent failure and prolong service life, so today into the metal equipment for everyone to explain the lifting machine maintenance knowledge, In the use of lifting machine must be safe use, scientific maintenance is the premise of safety and reliability.

Lifting machine maintenance knowledge a

The new lifter should be installed and debugted under the guidance of the manufacturer's technical staff. Do not change the machine parts and the scope of use in the process of use, so as not to cause direct or indirect damage to the machine; Don't overload or work too hard; Keep as far away from stoves, grease, oil, garbage, dust, ammonia, alcohol, heaters, faucets, obstacles, air humidifiers, thinners or spray adhesives as possible. It is recommended to use the original lifting machine parts when repairing and replacing parts. Pay attention to timely replacement of hydraulic oil according to the season, with 32# in winter, 46# in summer; The operator must also be trained in the operation of the lifting machine before it can operate the lifting machine.

Lifting machine maintenance knowledge two

In the process of operation, crowds should be avoided. When operating, the lifting machine should be steady, the landing should be slow, and the lifting machine should not be frequently lifted and landed. Once abnormal or failure is found, the doctor should be timely. In general, there are three reasons for the abnormal sound of the lifting machine: lifting overload, loosening of the motor fixing bolt, lack of lubricating oil at the slider. It is necessary to check the lifting weight, tighten the bolt or add lubricating oil according to the specific situation.

Lifting machine maintenance knowledge three

If the failure to lift occurs, there are five possible reasons:

1. There is air in the oil. Solution: loosen the exhaust screw and tighten it after discharging the gas;

2. Hydraulic oil solidification, solution: release hydraulic oil, re-fill qualified hydraulic oil;

3. Hydraulic oil leakage, solution: check whether the joint of each pipe fitting is tightened, whether the cylinder oil seal deformation, warping;

4. Motor reverse, solution: with the motor circuit diagram comparison, wiring is correct;

5. The motor does not turn, the solution: the motor is broken, replace the motor, the fuse is broken, the limit switch is broken, replace the limit switch. When there is oil leakage outside the lifting machine, you can check whether the connection is loose, whether the exhaust valve at the top of the cylinder is loose, whether the cylinder seal is leaking oil, whether the air hole is leaking, and whether the oil quantity is too much. Once the fault can not be solved, you should contact the manufacturer for maintenance in time, and must not work "with disease".
