Profile: Collis Civil Engineering specializes in mechanical and structural applications for railway signalling & other projects. We design and fabricate railway signalling support structures. Fabrication of points fittings and infrastructure are our other works. Our standard cantilever is based on a single tubular leg design. Each cantilever is supplied complete with a ladder top safety gate, an adjustable ladder bottom bracket giving vertical adjustment, a signal ID plate and its associated bracketing. Cantilevers are supplied in a hot-dip galvanized finish with all surfaces above and including the boom painted in black. All cantilevers are pre-install tested to ensure compatibility of parts. Foundation bolts can be supplied as an option. Cantilevers for use on electrified lines are supplied with dropper cages.
