Robbins Tunnel Conveyors

The backup systems are designed and built for every tunnel boring requirement. From simple, short gantry systems for small diameter machines to complex, remote-controlled double-track deck systems for maximum production using muck cars, the backup is matched to the tunnel. We also provide rolling stock (muck cars, segment cars), california switches, substations, ventilation and dust-control systems (scrubbers, booster fans, flexible ducting and ducting cassettes) to complete the system.

Main features of conveyors:

  • Conveyors systems powered by a heavy-duty head drive pulley designed preventing belt overloading during spart-up
  • Depending on space restrictions, storage cassettes can be mounted vertically as well as horizontally
  • Booster drives are designed for quick installation which becomes essential in long tunnels
  • Multiple drives are designed to share the load, maintaining proper belt tension under any load condition such as empty belt, partially or fully loaded
  • New patented curve idlers facilitate rapid muck removal and minimize belt wear in even the tightest TBM curves
  • Vertical conveyors provide the lift needed to keep up with our horizontal conveyor system
