Double Girder Crane

Double Girder Cranes:
Double girder cranes give a better height of lift in a given headroom as the hook travels between the beams. They are available in higher capacities than single girder and for heavy duty applications they can be supplied with open winch hoists.
Normally double girder cranes have 25 tonnes capacity and also in higher capacities. One simple advantage of the double girder design is the possibility to fit a walkway to the crane which gives maintenance access to many critical parts of the crane and often to overhead lighting etc.
