The improvement of construction speed and the reduction of physical labor among construction personnel have made work simpler and more technically operable, all of which are the values of mini lifting equipment. Currently, the most widely used mini lifting equipment is the "electric hoist", which is flexible in manual operation and has high safety, and can be divided into two types: wired control and wireless remote control. Nowadays, the vast majority of electric hoists are followed and controlled by operators on the ground using controllers.

　　The intermediate and heavy level work systems for electric hoists are:

　　When the lifting weight of the electric hoist in the intermediate working system is reduced by 30%, it is considered as a heavy-duty working system. JC40% of the electric hoist in the heavy-duty working system is generally used for heavy work, and the load is usually used under high rated values or specified safety factors. Electric hoists not only save time and improve work efficiency, but also have greater safety than manual handling. Let's hope that in the near future, with the development, the specifications and types of mini lifting equipment will become more diverse and advanced.
