The crane type should be selected taking into consideration the following points: (1) The span, height, component weight and hoisting volume of the structure, etc.; (2) Construction site conditions; (3) The status of the existing lifting equipment of the enterprise and the region; (4) Construction period requirements; (5) Construction cost requirements. The main reasons are as follows:   1.Cranes have a wide range of uses and many models. It is important to choose the appropriate bridge crane model according to different uses. Generally speaking, cranes can be basically divided into gantry cranes and bridge cranes. Generally speaking, gantry cranes are mostly used outdoors, and bridge cranes are mostly used indoors where walls are used as supports. For small lifting objects, you can choose a single-girder bridge (gantry) crane, and for heavy lifting objects, you can choose a double-girder bridge (gantry) crane.   2.Secondly, determine the crane model and tonnage: Each type of crane is divided into different models according to different lifting tonnage, functions, and grabbing heavy objects. For example, electric single-girder crane, single-girder gantry crane, beam bridge crane, etc.   3.In addition, you must determine the tonnage of goods that the crane you purchase will be able to lift. The tonnage cannot be too small, otherwise the crane will be easily overloaded, and if it is too large, it will easily increase the cost of purchasing the crane.   4.Determine the parameters of the crane again: The main parameters that need to be determined are: the span of the crane, which is the distance between the two outriggers; the lifting height of the crane, which is how high the heavy object needs to be lifted; the lifting capacity of the crane; the operating method of the crane, Generally, there are three operating methods for gantry cranes and bridge cranes: operating room operation, ground operation, remote control operation, etc. The selection of cranes is not only related to the life of the crane, but also to equipment and personal safety, to the improvement of productivity, to energy conservation and emission reduction. Reasonable selection of cranes is very important. There are many crane manufacturers across the country, and their production levels vary from good to bad. Choosing a good crane manufacturer not only has good crane quality and low failure rate, but more importantly, it is less likely to cause safety accidents.
