Helix delta-T has been used as the design tool and proven in many thousands of real conveyor installations in more than 25 countries around the world since 1991. The latest version brings you even more power and flexibility in your conveyor designs.

  • Calculate Motor Power and Belt Tensions
  • Use calculation methods CEMA, ISO 5048 or the Viscoelastic method for low resistance rubber belts
  • Dynamic Analysis calculation for Starting and Stopping for long overland high power conveyors
  • Databases for quick equipment selection for Belts, Motors, Gearboxes etc.
  • Calculate Vertical Curve radii and super-elevation (banking) angles for Horizontal curves
  • Share conveyors with other users for project collaboration
  • Open multiple conveyor files in your browser tabs
  • View Belt Tension graphs and generate pdf Reports
