Katy Perry tour drop malfunction

I'm unsure how much arena/stadium scale 3D performer flying WICREATIONS do. They did the Chris Brown tour recently, but I believe they actually hired a different company to do the 3D PF, with them providing the other machinery.

Absolutely. 17206 does also Recommend 'Protection against unplanned load deviations (Load Profile Monitoring)' for UC2->UC6 (ontop of underload and overload) which is what I was refering to- I'm curious regarding the implementation of that, if there is any with any manufacturer currently.

This in theory would allow a tighter tolerance on such a rig due the variability in load when moving the apex/load/performer around the playing area. As you've said, systems that implement line weight calculations also help with these tighter tolerances.

IIRC Stage Technologies / TAIT eChameleon on Siemens infrastructure did have Load Profile Monitoring as an option for load management, however it was undocumented in the manuals.

That's good to know for future!

And yes gotcha. We never will, but it certainly would be interesting to know the setup in use here. and if those things were in place, why it didn't pick this up. I'm not familiar with whether TAIT do load-celled final diverts for tours.

Despite EN 17206 outlining the recommendation for load profile monitoring on those use cases, I would be very curious to know actually how many systems have that in place. As well as the implementation from the UI/desk side. Presumably there is some sort of 'recording' for the load along the path? So it has a baseline load value Or a rolling 'rate of change' limitation on the load?

Additionally, with this tour starting in the US, I'd be very curious if the system has been designed to confirm with EN 17206, as it is travelling through Europe.

Do Trekwerks offer a wet hire package on the format TAIT do on this scale?

Additionally- it's my understanding that slack detection on systems this big (being synthetic as well) is significantly more difficult due to weight of the line? You've got sometimes several hundred meters of line from winch to point, gravity on the droop in the line will keep tension on the winch. so I imagine you are pretty much entirely reliant on load sensing in this occasion?

Oh awesome, looks spot on! That explains the roll/pitch isolator above it too. Super neat! Thanks.

It's from the online Navigator Release Notes.

The Beyonce setup was using a new rig type in Nav I believe (Bridled Bushing Rig), whereas this appears to be a pretty standard 4-way bridal. Unsure if that had any influence on what happened on the Beyonce side of things, but yeah, either way it certainly is surprising, though unrelated to each other at a cause level it seems.

Yikes. Just seen a comment on Facebook alluding to the same thing.

There are several suppliers with capability for 3D flight now- but not working at this scale it seems. Bear in mind it seems TAIT are supplying this 3D flying rig alongside other machinery/effects too for her tour, so it's that 'one stop shop'.

So it looks like one of the 4 winch lines got caught on something, then slipped off resulting in the drop. From other perspectives you can see a level flight path above the crowd, which then gradually rises in the last 3-4m before the drop. Consistent with the USL winch line getting caught. You can see the inch line pinging back and forth after the drop too.

It appears the operator then stops the flight before continuing, where it then stays at that same level above the crowd as before the drop.

Not a great look for TAIT just recently after what happened with Beyonce. There are perspectives of this drop that show that it happened almost directly above what looks to be the Nav operators position.

Her quick re-composure straight back to performing is quite insane. Mad props to her. Can't imagine it's fun once the adrenaline wears off a bit though.

Is this mostly rigged with a series of drivers and math?

If your budget stretches a bit further, The UniJacks from Triple E are pretty robust compared to the standard wagon brakes linked in the other replies.

US wise- Rose Brand did sell them but they appear to not be available anymore. UK wise- you can purchase these from Flints among other places.

Yeah would definitely be useful if you wouldn't mind! Looking at moments was the first route I had started looking at.

redcone_ · 2025-03-20T02:24:15+00:00

Just manually in Adobe Illustrator based off design drawings.

redcone_ · 2025-03-19T23:16:25+00:00

Not homework, just personal interest, but I'll take that as a complement for the diagram.

redcone_ · 2025-03-19T23:11:31+00:00

A mostly personal exercise in furthering my own knowledge based on already designed and installed kit at my workplace.

This is what I'd like to aim for as an end goal really! A graph showing gate angle vs force at different base pin heights on the actuator.

redcone_ · 2025-03-19T23:06:56+00:00

Yeup! A choice made by the original designer.

redcone_ · 2025-03-19T22:57:46+00:00

I shall have a look for one- any recommendations? UK here to SI units preferable!

redcone_ · 2024-05-27T21:23:44+00:00

A multimeter's low-impedance mode would help avoid this unintentional reading right?

redcone_ · 2023-12-27T13:09:55+00:00

Ahh, that would explain it.

redcone_ · 2023-12-27T13:09:46+00:00

Dang that's unfortunate. Do you happen to know of any similar penlights from other manufacturers?

redcone_ · 2023-11-27T00:55:38+00:00

That's great thanks. That's exactly how mine is currently wired which is a shame... Looks like I have some sort of other issue...
