Rated for Production: APEX Roof Load Ratings and Rigging Capacity

A modern show hangs a lot of weight overhead: line array audio, lighting trusses, moving lights, LED video walls and motors. A mobile stage is only as useful as the load its roof can safely carry — and how clearly that load is documented. Every APEX model comes with engineered, published ratings so production teams can plan the rig with confidence.

Published Ratings by Model

• APEX 5040 GEN3 — 102,000 lb load rating, the highest in its class, with an overhead beam system designed to eliminate traditional no-fly zones.
• APEX 4240 GEN3 — roof structure rated to 97,600 lbs; columns and towers rated to 144,000 lbs combined (16,000 lbs on each corner tower and 40,000 lbs on each mast column).
• APEX 2016 — 800 lbs on each flybay with 3,400 lbs total roof capacity, a strong rating for a compact stage.

Beam-by-Beam Capacities

The engineering spec sheets go further than a single number. On the 4240 GEN3, for example, every member is rated individually — upstage and downstage beams, spanners, trusses, slide-out frames, PA beams and side extension beams — with notes on which loads are subtracted from their supporting members. That level of detail lets riggers place each point correctly.

Check Your Plot Before Show Day

Use our APEX rigging calculators to enter each hanging point and see every beam, spanner, tower and mast checked against capacity in real time, color-coded green, yellow or red. Download the full spec sheets for your model, and send us your plot for review.
