The TunnelRat is not new but is being readied for a potential project that will require it’s services. The Tunnel Rat can fit into tight spaces where even the Mole cannot venture. It has outriggers with wheels on the ends that help keep it properly positioned in a tunnel. The cutting nozzle is rotated by a hydraulic motor and the whole assembly pulled through the tunnel by a winch.
