Electric hoist maintenance manual

Pre-manufacturing quality determines the life of electric hoist, but if you want to extend the life of electric hoist in the later period, you can’t do without good maintenance. Proper maintenance can not only prolong the service life, but also increase the flexibility of electric hoist operation. After purchasing electric hoist, the general staff will tell us that it needs regular maintenance. If the staff does not specify in the manual, its maintenance work is very important. It can not only reduce the damage of parts, but also extend its service life to a certain extent and improve the safety factor.            

 The maintenance frequency of electric hoist is proportional to the use frequency. If it is used every day, it needs to be cleaned up and maintained after each use. If it is not used for a long time or occasionally, it can reduce the maintenance frequency. In the case of long-term storage, it can be cleaned up regularly and then smeared with appropriate amount of grease. The purpose of this is to avoid rusting of parts. Electric hoist maintenance does not specify a specific time, each user's use of different maintenance frequency is also different, we can formulate corresponding maintenance measures according to their own use frequency.

 With the development and progress of science and technology, as well as the construction industry and the new construction of major factories, the use of electric hoist is also increasing. At the same time, the maintenance of electric hoist is more important. People who use electric hoist for a long time all know that maintenance and non-maintenance, the service life can be much worse. If maintained properly, service life can be greatly increased and construction cost can be saved.

 If the electric hoist is newly installed or installed without disassembly and inspection, it needs to be run empty. Of course, in the process of installation, if the installation is not completed, do not turn on the electricity for trial operation. In addition, before the normal use of the hoist, the rated load should be checked and the distance from the ground should be increased. Static load test operation is required. The main purpose is to check whether it is normal or not. Especially in the use process, in the allowable environment, or more than the rated load  for use.

 In addition, when installing electric hoist, it is necessary to check whether the lower limit device is working properly, or if it exceeds the limit value, the hoist will be out of the predetermined orbit and cause accidents. When the hook is about to move to the limit position, it is necessary to control the speed and keep a certain distance to avoid the damage of equipment caused by too fast speed. In order to ensure safety in use, steel wire rope should also be used, and power supply should be switched off in time after use. It should be operated by  professionals in daily use. At the same time, training should be carried out before operation of hoists, including operation specifications, related matters and so on. Only when the relevant knowledge points are fully grasped, can the use effect be ensured in the process of use. Especially in the daily use process, once equipment failure and other issues occur, should be cut off immediately in the other use process, special attention should be paid to the  situation of vulnerable parts.

 Maintenance and maintenance of electric hoist is mainly to maintain the good working state of the equipment and use appropriate technical measures to maintain or restore its technical performance, because various physical and chemical effects in use will cause equipment wear, fatigue and corrosion, maintenance can restore or minimize wear and tear, give full play to its role.

 To sum up, it is very necessary to improve and standardize the maintenance process of electric hoist. Before its application, electric hoist must carry out scientific debugging work, and then pay attention to the maintenance of brake and reducer during the overhaul. This can greatly prolong its service life and improve its efficiency for a long time.
