Krandura

Double Girder Overhead Crane

A double girder overhead crane carries the trolley between two main girders, or on rails on top of them. That arrangement raises the hook for the same building height, stiffens the crane at longer spans and heavier duty, and provides a platform for the trolley, rope drum and control panel. Use it when headroom is tight, lift height is large, the duty class is heavy, or the crane needs a walkway.
