What issues should users carefully consider when selecting a suitable crane for a hoist?

In the construction industry, we often see many cranes equipped with additional lifting devices to improve the overall efficiency of the machinery. The crane hook plays a very important role in the crane; its own tonnage is one of the key factors affecting the lifting capacity of the crane. To this end, experts advise users to keep the following points in mind when making a choice: when lifting, the tonnage of the crane must be taken into account in the calculations regarding the lifting capacity. At the same time, it is also necessary to understand the length and size of the crane’s boom. It should be noted that when a crane moves up and down, the longer the boom extended by the crane, the lower will be its lifting capacity. Furthermore, based on certain calculations and practical experience, it is known that the optimal lifting capacity of a general crane, as well as the maximum lifting mass of the entire machine, should ideally fall within the 70%-90% range. At the same time, when selecting it, the relevant margins also need to be calculated. Finally, we also need to select the appropriate crane capacity based on factors such as the type of goods being lifted and their weight. During lifting, to ensure the operational efficiency of the entire equipment, the elevation angle of the crane’s boom must not be less than 40°.
