Turntable People / Large Platform Loading¶

LIKELY SAFETY CRITICAL

Summary¶

Operators discussed putting multiple people or large surfaces on turntables. The practical advice was to use rigid, well-secured platforms, keep actors close to center, and avoid large off-center loads that can trip the turntable. Any human-load turntable setup needs formal load/safety review.

Symptoms¶

You need to put one or more people on a medium or large turntable and want to know the load and platform requirements.
The turntable is tripping faults during a shoot with actors because they are standing too far from the center.
You are building a large deck or surface on top of a turntable and need to understand how platform rigidity and off-center load affect turntable safety.
You need guidance on what safety review and E-stop access is required before rotating a human-load platform.

One setup used a small wooden plank screwed to the turntable, with a larger board screwed on top. Main problem was off-center actor load: if actors were far from center, force was too much and the turntable tripped. Keep actors as close to center as possible and use a more rigid platform.

WhatsApp Excerpts¶

2025-12-06 10:41 - Mike Greenberg asked whether anyone had put multiple people on the medium turntable, and whether there was a good way to put a large surface on it securely so it would not tip as people stepped onto it.
2025-12-06 10:51 - Ante reported using a small wooden plank screwed onto the turntable with a larger board screwed onto that. The main issue was actors standing far from the center: the off-center force was too high and the turntable tripped. The workable approach was to keep the kneeling/standing actor as close to the center as possible and use a less flexible support.
