There are many structural types of gantry cranes. The performance of gantry cranes produced by different gantry crane manufacturers are also different. In order to meet the needs of customers in different fields, the structural forms of gantry cranes are gradually becoming more diverse.
In most cases, gantry crane manufacturers divide the structure of the gantry crane based on its main beam form. Each structural type of gantry crane has different working characteristics, especially in terms of the main beam form.
Box type single main beam gantry crane
Usually, gantry crane manufacturers will divide the main beam form from two dimensions, one is the number of main beams, and the other is the main beam structure. According to the number of main beams, gantry cranes can be divided into double main beams and single main beams; according to the main beam structure, gantry cranes can be divided into box beams and flower rack beams.
The biggest difference between the use of double main beam gantry crane and single main beam gantry crane is the different weight of the lifting object. Generally speaking, for industries with higher lifting tonnage or larger lifting objects, it is recommended to choose a double-main beam gantry crane. On the contrary, it is recommended to choose a single main beam gantry crane which is more economical and practical.
Flower stand type single beam gantry crane
The choice between box beam gantry crane and flower girder gantry crane generally depends on the working scene of the gantry crane. For example, flower girder gantry crane has better wind resistance performance. Therefore, people who carry out lifting and transportation operations outdoors usually choose flower girder gantry crane. Of course, box beams also have the advantages of box beams, which are that they are integrally welded and have good rigidity.
