Demag Standard Single Girder Under Running Cranes

Underrunning box girders are designed with same optimal combination of strength and lightweight design as our toprunning box girders. Standards include 2-speed hoist and bridge with 2-speed, single speed and push trolleys available. Standard options include variable speed variations for all travel and hoist drives, dual hoist arrangements and outdoor operation.

• Our girder construction utilizes two types: WF beams or our unique box girder design.
• WF beams are used for cranes up through 10 ton capacity and 60 foot spans.
