Shri Cranefab manufactures “Double Girder Overhead Cranes” in SWLs ranging from 1T to more than 50 T. These cranes can either incorporate standard “SHRI” Hoists (up to a SWL of 15T) or fully customized open winch type crabs. Double Girder Cranes can be offered for a very large range of spans, large range of height of lift as well as HIGH speed. They can also be provided with multiple hoisting trolleys running on the same bridge.
Precise control of up/down motion and/or travel motion can be achieved by fitting Variable Frequency Drives in the panels (optional).
The double girder cranes are used when heavy loads and wide spans are required. Double girder cranes consist of two torsion-free box girders. This makes double girder cranes especially suitable for lifting and transporting loads over 10 T and for span of more than 25 m. Double girder overhead cranes are available with load capacities up to 50 T and with spans up to 50 M. Heavy duty end carriage joints ensure positive contact of all four/eight wheels with the track. The profiles of the main girder are optimally produced using computer so that maximum performance with a minimum of deadweight can be achieved.
