Robbins Boring Machine

This is a large scale model of a 7-meter Tunnel Boring Machine (TBM) which was constructed for The Robbins Company in Renton, WA. Robbins is one of the foremost builders of TBM’s in the world. This model was commissioned by The Robbins Company for use as a sales tool and is one of many tunneling machine engineering models we have fabricated for Robbins over the years.
