A Project of Firsts
Robbins introduced HP-TBM™, also known as the High-Performance TBM, for the Norwegian contractor Statkraft Anlegge when a project called for very difficult geology to be bored. The three HP-TBMs employed had substantially higher capacity main bearings, more cutterhead power, and more cutterhead thrust than any other hard rock TBMs of that size at the time (3 to 5 m in diameter). To withstand all of this additional thrust and power, Robbins developed the new high-capacity 19″ cutter with wedge-lock mounting system.
