What happened if rocket scientists trying to get into film business...

Well, I think I can prove that it is safe!

 

Base on the video, and using the operator foot dimension as a measurement unit (1 foot).

The concrete is:

Width = 6ft

Length = 12ft

Height = 0.5ft

Density = 143 lb/cubic foot

The weight of the concrete will be; W = W * L * H * D

6x12x0.5 x143 = 5148Lbs = 2335Kg = 2.335 metric ton = 2.5 US ton

 

 

I really don't think we should recommend this method. Besides, I think your calculations may be a little out, it certainly doesn't look 6ft wide for a start. Granted it will still be very heavy but and may be unlikely to topple but I'd still rather do it with the proper equipment.

 

 

Mike,

 

It's fine

Eric,

 

Which aspect? I'm not saying lifting a person with a forklift can't be done safely, it can and I've done it many times. However, this is definitely not the way I would go about it.

Did a shot on a forklift once.

We craned up higher than a huge stack of containers at Port of Houston. The stability of the forklift was beyond question.

 

Having said that, the math above may or may not be spot-on but the video does make it appear that the fellow was on a fairly stable platform. Safety and support is key as Jerry pointed out. Me, I'd want a flat plate behind me and below me. Pallet with 1" ply nailed to it, handrail, etc. Falling from 15 feet could be painful.

 

Oh wait...

I do agree with Ken's calculations. But I also agree with Erik, Sanjay and Jerry..

 

I myself did this a few weeks ago:

 

 

 

When I first saw this scaffolding on that Fisher 10 (100x70cm or 38x26inch base) I was almost to say no (somewhat of a safety freak as I am), but then after climbing on it (without the steadicam), hanging on it like a monkey to see how easily it could tip over- didn't at all!, and asking the grip to lower the platform for about 20cm (8 inches) for safer roof lamps clearance, I climbed on, hard mounted the steadicam with my CG-s and steadicam CG-s common CG (if that makes any sense in a sentence) somewhere in the middle of the platform, and we got the shot very nicely done in 2 or 3 takes.

 

I also must add, that I was introduced to this idea before the whole shoot began and it was all safe (seemingly), so it wasn't the someones last minute crazy idea without any proper preparation.
