50t Double Girder Overhead Cranes with Two Torsion-free Box Girders
?
This is QD box type double beam Electric Overhead Travelling Bridge Crane with 50t capacity which use winch as lifting mechanism. When heavy loads and wide?duty are required, the double?beam?electric?overhead travelling cranes for workshop show their strength. They consist of two torsion-free box girders. This makes them especially suitable for lifting and transporting heavy loads.?
They 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.
