The compact solution for long, small diameter rock bores.
Win your next bid with the pinpoint-accurate Remote Controlled Small Boring Unit (SBU-RC). The Robbins SBU-RC was developed from many requests for a cost-effective machine that could excavate small diameter tunnels in rock with strict line and grade requirements. The Robbins SBU-RC uses a smart guidance system, allowing the machine to work unmanned during small diameter, long crossings up to 500 ft (150 m). If your next small diameter project is line-and-grade-sensitive or requires excavating long distances, then the revolutionary SBU-RC is your solution.
What is an SBU-RC?
The SBU-RC is a motorized, remotely operated mixed ground and hard rock boring machine for use with standard Auger Boring Machines (ABMs) or pipe jacking systems. In a launch pit or shaft, the SBU-RC is attached to the lead steel casing. The ABM or pipe jacking system provides thrust through this steel casing. The SBU-RC is optimized for line-and-grade sensitive bores such as gravity sewers, and operates in much the same way as a Motorized Small Boring Unit. If you are not familiar with the SBU-M, read up on this proven machine on the Motorized SBU page.
The SBU-RC is a similar concept to the SBU-M with the following additional features:
Smaller diameter machine: currently available between 24 inches (600 mm) and 42 inches (1,100 mm)
Continuous steering from an operator’s station at the surface using a smart guidance system
