Belt Conveyors for Spoil-removal Systems

These are used chiefly during mechanised excavation of a tunnel by a TBM in order to carry spoil out, also called a belt conveyor spoil-removal system.

SAMMI has been working in this sector for several years, supporting its clients from the very first stages of design then through analysis and technical studies, taking the following factors into consideration:

  • Section of the tunnel, depending on the excavation diameter of the TBM
  • Plano-altimetric inclinations and curves
  • System for suspending the belt in the tunnel
  • System for storing the material outside the tunnel
