Lifting machinery refers to the electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, and its scope is specified as a lift with a rated lifting capacity greater than or equal to 0.5t; Tower cranes greater than or equal to 40t m, or loading and unloading bridges with productivity greater than or equal to 300t/h) and cranes with a lifting height greater than or equal to 2m; mechanical parking equipment with layers greater than or equal to 2. Most of the accessories of single-beam hoisting machinery and equipment are made of metal, so how to avoid rust and corrosion when using them.
1. Pay attention to maintenance in normal times. If you find that there is too much dust on the surface of the crane equipment, you should clean it up in time. Long-term accumulation is not conducive to the normal heat dissipation of the equipment. At the same time, pay attention to some oil pipes so as not to cause blockage, etc. Otherwise, it is easy to cause the internal temperature to fail to dissipate. Remember to completely replace the oil on a regular basis, which is conducive to smooth oil circulation of the equipment.
2. Corrosion not only damages the image of the external structure of the equipment, but also can easily cause the crane equipment to fail to work properly after long-term corrosion. The common corrosion mainly includes contact with air and rain, which can easily cause corrosion of the equipment. There is also strong acid and alkali, etc., which will also have a great damage to the equipment.
3. For rain and other conditions, the operator of the single-girder crane should pay special attention to the equipment not to be placed in a humid place for a long time, and should try to be in a dry and ventilated place. If water has entered the equipment, it should be dried if it is not used for a long time Good, to prevent it from rusting and corrosion. For the environment around the equipment, be careful not to place some strong acid and alkali objects, so as to avoid the phenomenon of damage to the equipment caused by people's careless actions.
