GMS mechatronics from Austria has developed a fully automated solution to manufacture tunnel lattice girders.
As the labor costs for the production of tunnel girders dominates the cost structure, the newly designed production cell from GMS enables manufacturers of tunnel girders to cut costs immediately by 50%.
Tunnel girders show a lot of different shapes and dimension. The new production system is capable to cover all these characteristics. The new solution was developed by Franz Filzmoser, well known for highly automated lattice girder welding lines, which serve concrete precast-plants with high-quality lattice girders.
Lattice Girders for tunnels are lightweight, three-dimensional steel frames, typically fabricated of three primary bars connected by stiffening elements. Lattice girders in conjunction with shotcrete achieve an excellent level of support in tunneling. They consist of steel bars welded together in triangular or rectangular pattern and they are made to suit the shape of the tunnel. This combined system acts as an armor that provides balanced support and reduced consumption of shotcrete.
GMS is an Austrian company in Wels, which is focused on trading and manufacturing of lattice girder production lines.
