Double girder cranes consist of two torsion-free box girders. This makes double girder cranes especially suitable for lifting and transporting loads over 10 Ton and for span of more than 25M. Double girder overhead cranes are available with load capacities up to 200 Ton and with spans up to 40 M.
On a double girder crane, there are two girder beams that make up the bridge and they’re supported by an end truck on each side. In most instances, the trolley and hoist run on a rail installed on top of the bridge girders.
Double girder cranes can be either top running or under running in design. A top running double girder bridge crane will provide the most overhead room, as well as the greatest hook height.
Double girder EOT Crane are recommended for heavy-duty applications where the crane has to handle heavier capacities and longer spans.
Double Girder bridge cranes are ideal for lifting heavy loads and can be used in more frequent operation than a single girder crane. They can also be used both indoors and outdoors, in a bridge or gantry setup, and are frequently used in mining, iron and steel production, railyards, and shipping ports.
