Even in the most well-planned projects, tough conditions can come up. Everything from squeezing ground to fault zones to sudden inflows of water and mud can delay your project significantly. Find out how our field service teams have dealt with the most challenging
The SBU-RC is a game-changer for the trenchless industry, making long, line-and-grade-sensitive crossings possible at small diameter. The SBU-RC is an unmanned, articulated mixed ground and hard rock boring machine for use with standard Auger Boring Machines (ABMs) or pipe jacking systems.
Robbins’ continuously advancing conveyors are designed to increase the efficiency of muck removal and vastly simplify tunneling logistics. Robbins Continuous Conveyors have been successfully employed on nearly 100 projects worldwide—more than any other TBM tunnel conveyor manufacturer.
If the geology of your project includes high permeability soils combined with sections of low permeability ground, the Crossover XSE is the solution for you. Not all projects fit within the parameters of specific TBM types, and at Robbins we believe that your machine should be custom-engineered for your unique project requirements. That’s where the Crossover Series of TBMs comes in.
Whether the geology of your project includes sections of hard rock, soft ground, boulders, or a little bit of everything, Robbins has a solution for you. Not all projects fit within the parameters of specific TBM types, and at Robbins we believe that your machine should be custom-engineered for your unique project requirements. The XRE TBM offers the best features of both EPB and Hard Rock Single Shield TBMs.
Robbins Main Beam machines feature High Performance (HP) options including large diameter cutters, variable frequency electric drive motors, and adaptable ground support systems. Their design consists of a rotating cutterhead that holds disc cutters (ranging from 17 inches to 20 inches in diameter), which are positioned for optimal boring.
Robbins has integrated over 60 years of TBM design and jobsite experience into our innovative Earth Pressure Balance (EPB) TBMs. Robbins EPBs are engineered with the same rugged structure and time-tested designs of our hard rock TBMs, but their function is purely for soft and mixed ground.
Robbins Double Shield TBMs are the long-haul specialists of the tunnel boring world. Since their development in 1972, Double Shield machines have excavated some of the world’s longest tunnels and achieved world records in the process. The secret lies in their ability to simultaneously bore and line the tunnel with segments, making for faster excavation even in difficult ground.
Robbins designs and manufactures the most technically advanced disc cutters worldwide with a commitment to high quality and continual improvement. No matter the geology, no matter the machine type or manufacturer, no matter the size- Robbins has the cutting solution to meet your needs.
The Robbins Rockhead is ideal on longer utility installations (over 500 ft)
where line and grade are critical. The Rockhead is available in Double Shield (SBU-RHDS) or Single Shield (SBU-RHSS) models. The Double Shield Rockhead is self-propelled using a gripper system. The Single Shield Rockhead must be used in conjunction with a pipe-jacking system or primary liner erected in the tailshield. Muck can be removed using a small invert auger or muck cars.
