Read before rigging
- These calculators are for use by qualified personnel only.
- All rigging loads applied to APEX stages should be reviewed by an APEX technician prior to deployment.
- All rigging attachment to structure must be done per manufacturer specifications using overhead-rated rigging equipment.
- Complex rigging plans, or any plan within 10% of allowed maximums, should be reviewed by an engineer prior to deployment.
- Vertical loads only. Loads subject to wind — backdrops, scenic elements, video walls, etc. — need engineer review for the horizontal forces they induce.
- In all cases the High Wind Action Plan (HWP) is in effect while the stage is in use.
Prefer Excel?
Download the original APEX workbooks. They require desktop Microsoft Excel with macros enabled — see the setup instructions.
