We have completed the installation of a set of double-girder gantry cranes in Poland. This is a set of MG type 20 ton gantry cranes, which are shipped from Qingdao port to Gdynia port by sea. MG type double-girder gantry crane is mainly used for loading, unloading and handling materials on open storage yards. The lifting capacity is large, and the operation form is divided into two types: ground and driver’s cab. The gantry crane has the advantages of simple structure, convenient maintenance and light weight. The double main girder gantry crane has the characteristics of strong bearing capacity, large span and good overall stability.
