Bigge’s Elevated Modular Girder System is a modular, pin connected system specifically suited for the installation and removal of reactor vessels and power plant equipment for the nuclear and fossil power industries. Bigge’s proprietary system, along with its high-capacity girder inventory, allows for the fewest possible support columns, greatly reducing system installation and dismantling requirements. In combination with strand jacks and hydraulic gantries, Bigge has deployed elevated runways in dozens of projects.
