Welcome to the Helix delta-T Conveyor Design Program - an essential tool for engineers, contractors and plant operators to quickly and easily optimise Conveyor system designs. This program includes features:

  • Tension and Power Calculations
  • Equipment Selection from Databases for Belts, Idlers, Pulleys & Shafts, Gearboxes, Motors, Fluid Couplings, Brakes etc.
  • Draw a sketch of the conveyor Profile and also view a scale drawing and a 3D line model of the conveyor
  • Calculate Vertical Curve radii and super-elevation (banking) angles for Horizontal curves
  • Calculate using CEMA, ISO 5048 or the Viscoelastic method for low resistance rubber belts
  • Add any number of Conveyor Pulleys, Drives, Loading points, Trippers, Brakes etc.
  • Create pdf Reports and view directly in the browser or save
  • Copy and Paste Raw data directly into a spreadsheet
  • Create and download an excel .csv Conveyor Comparison List comparing multiple conveyor files

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 Helix delta-T Online brings you even more power and flexibility in your conveyor designs.

Build your conveyor from scratch in on a drag and drop canvas by selecting the node and entering it's x, y, z coordinates.

Copy and paste conveyor x, y, z coordinates from a spreadsheet directly into your Online Conveyor File or upload an existing Helix delta-T6 .xml Conveyor design File

Use one of our Demo Conveyor Models as a template to get you started. Just Copy the file and rename it.

Calculate with the ISO, CEMA and Viscoelastic calculation methods

Determine belt tensions at all points along the conveyor, drive traction, take-up weights, starting and stopping times and more..

Generate reports including Belt tensions, design, take-up and Drive traction, resonance, starting and stopping, vertical and horizontal curves, equipment and pulley reports.

Instantly view or download reports in .pdf format.

View bar and line graphs of belt tensions at each point under different loading conditions and running states to quickly and easily understand the conveyors behaviour

Use our extensive equipment databases for quicker design or to auto select equipment. Our Databases include:

  • Belts
  • Brakes
  • Fluid Couplings
  • Gearboxes
  • Holdbacks
  • Idlers
  • Materials
  • Motors
  • Pulley Shafts
  • Pulley Shells
  • Pulley Widths
  • Shaft Couplings
  • Starters

Save your own equipment in your own database for use in other conveyors

Consolidate your companies equipment into your own private databases

Store all your conveyor models online in your own database

Give another user permission to view or edit your conveyor for project collaboration

Give another user ownership of the conveyor document

Lets have a look at a few demo files

Demo 02 - C223 Iron Ore Loadout
Demo 06 - C344 10km Overland Conveyor
This Demo shows a basic conveyor layout and is a good starting point to familiarise yourself with the program Overland conveyor 10km long with 2 drives and Brake
