To a large extent the type of supporting structure used in handling equipment depends on the function and the support spacing distance required.
For support spacing distances up to 12 m, self-supporting framework trusses can be used.
For support spacing distances up to 25 m, the continuous girder bridge made of IPE profiles is a suitable and convenient solution.
If the support spacing distance exceeds 25 m, conventional framework bridges like those used in railway construction are a practical option.
For very large support spacing distances up to 76 m, the possibilities of using an air-supported belt conveyor should be considered.
