Crane Doors

Champion Door overhead crane door system

Sealing craneway opening with tight door 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 crane door solutions are especially designed to do away with the problems traditionally associated with craneways. Large industrial halls where overhead 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 opened when the craneway is in use. This solution is extremely practical and very flexible to operate. The crane door fabric is UV-protected and extremely durable against wear and tear, windows and burglary protection are available as an optional accessory.
