-
Introduction:
This trolley hoist or crab hoist is a double girder crane wire rope hoist which is mounted on a trolley frame. It is composed of a hoist and a trolley frame, and the frame is also driven by motors and travels on rails fixed on the 2 crane girders. This trolley hoist is made according to European FEM standards and Germany DIN Stands.
