What’s Going On? A Quarterly Worldwide Jobsite Roundup
At any given time, Robbins TBMs are operating at dozens of jobsites around the world. Our dedicated Field Service personnel take video and pictures of the TBM progress often, so we’ve decided to offer a quarterly roundup of what’s going on in picture and video format–from deep TBM assembly in New York, USA to an epic TBM launch in the Himalayan mountains of Nepal. Read on to found out the latest.
TBM Assembly in a Deep Shaft in New York, USA
A 6.8 m (22.3 ft) Robbins Single Shield TBM, designed for water pressures up to 20 bar, is undergoing assembly and testing at the Delaware Aqueduct Repair Project. The TBM will be launched from a starter tunnel at the bottom of a 274 m (900 ft) deep shaft.

Crossover Machine Startup in Akron, Ohio
On October 19, a Robbins 9.26 m (30.4 ft) diameter Crossover (XRE) TBM launched below Akron, Ohio, USA to bore the OCIT tunnel. The machine is excavating in soft soils that will transition into mixed face and then full face shale. Before its launch, personnel at the jobsite filmed the cutterhead testing in a unique way.
