40 Ton 50 Ton 100 Ton Double Girder Rail Mounted Gantry Crane 18 - 35m Span
Compared with the single girder crane, double girder gantry crane is more powerful and the gantry crane design is more complex. It is mainly used to lifting heavy loads, with high working strength, in sever working condition, or with other special working demands.The maximum lifting capacity is almost unlimited. The biggest double girder crane we have made is 900 tons. The span and lifting height and all other main parameters is also complex. For more technical details, please see below parameters.
