Truss load distribution calculator
Why truss load math matters
A truss line is rarely one clean number. Movers, video, audio, and scenic stack weight across spans and motors. On tour, you need per-motor loads you can hand to structural, the house, or your own crew without rebuilding the spreadsheet every room.
RigThis distributes loads across your truss layout and surfaces the numbers in a format you can verify on site—then send per-motor values into bridle math when you need to hang picks off the same run.
Dynamic Load Factors (DLF)
Automated moves change effective load. RigThis supports Dynamic Load Factors so shifting weight from movers and effects does not sneak up on your motors after the static pass looked fine.
- Layout truss with gear placed where it actually sits
- Apply DLF for automated or moving elements
- Read per-point and per-motor distribution
- Pass loads into bridle calculations when picks hang off the truss
Built for load-in, not the office
The UI is designed for dim venues and fast calls on the floor. Saved venue specs in Pro let you pull grid heights, ratings, and room-specific details when you walk the building again—without mashing every job into one generic profile.
Works with bridle math
Truss distribution and bridles are connected workflows. RigThis lets you move from motor loads to bridle geometry without retyping everything. See the bridle calculator for 2-leg and 3-leg solver details.
