Double girder overhead cranes are available with load capacities up to 50T and with spans up to 35 m. Articulated end carriage joints ensure positive contact of all four wheels with the track. The range of fixing arrangements allows the appropriate integration of double girder travelling cranes into new buildings as well as into existing buildings. Just as with all other types of double girder travelling cranes, the profiles of the main girder are optimally produced using computers so that maximum performance with a minimum of dead-weight can be achieved. An advantage that has financial benefits.
