Crane Doors

Sealing craneways with door solutions improves the building’s energy efficiency considerably and also reduces dust and noise problems.

Champion Door fabric fold-up crane door technology is ideal for large special doorways required within the industrial sector. Champion Door craneway door solutions are especially designed to do away with the problems traditionally associated with craneways. Large industrial halls where cranes are used can be divided with special door solutions that cover both the craneways and access doorways with a single fold-up door assembly. The crane door can also be used separately and the whole door can be raised when the craneway is in use - saves energy in cold climates. This crane door system is extremely practical and flexible. The fabric is always UV-protected and extremely durable against wear and tear, windows and burglary protection are available as an optional accessory.
