Patent DE-4314587-A1 (DE)
Title: Conveying and transport device
Inventor: BORDE HELMUT
IPC: B65G15/60
Filed: 1993-04-29
Abstract: Known conveying devices often consist of a functional separation of       - supporting structure (bridge)   - conveyor (trestle)   - housing (weather/environmental protection).   For example, conveyor bridges consisting of a lattice structure with a multiplicity of nodal points necessitate a considerable outlay in terms of production (a plurality of different profiles and individual parts, cutting to size, welding, completion, etc) which can be mechanised/automated only with difficulty, assembly including. The abovementioned device contains the combination of the abovementioned functions into one structural part and largely cost-effective mechanised/automated production, including the assembly of the tubular body. Device and its part solutions are suitable for different conveying/transport tasks in the case of stationary/mobile plants.
