The Bi-Bloc Weld Shear EGH1/EGH2 is a hydraulic rail shearing machine designed to shear off excess metal after aluminothermic welding of Vignole rails.
During aluminothermic welding, a deadhead of excess metal remains above the rail head. This was traditionally removed manually with a hammer and chisel, but the Bi-Bloc Weld Shear automates this process and removes the risk of damaging the rail. The shear is operated by a separate hydraulic unit, either with an electrical motor or a gas power engine, which makes it lighter than other sheering machines as the hydraulic unit is not mounted on top.
