Tricks for stacks
« on: July 07, 2017, 05:07:31 pm »

Any tricks you guys have for building tall stacks?   Let's say 2+ 2x18 subs stacked - gets in the 4-6ft height range.  How to get giant mains (100lbs or more) up that high safely?   I can't imagine OSHA is cool with standing on rack cases or the back of a truck. 

Thoughts?

I've seen it done off the back of a ryder truck with a lift gate.  They were able to back up to the stack and place EAW 850s on top up the subs without breaking a sweat.  I have used two ladders but the tops weren't that heavy.
You could use scaffolds in front of the stacks and place boards at different levels to help with the lift.

I know a couple brothers who stacked their dads 850s two high over two high SB1000s the old fashioned way, by climbing and lifting.  They were teenagers and that was just the family business.  Both are touring musicians now, probably a better life.  ;)

Since this is big boy forum, I'd say use the big boy ways:  lift truck of whatever configuration or type is suitable for the terrain or facility.

When I was out west, it was fairly common to see 3 tops over 3 subs for street fairs. Often the tops had a fly bar and Hoist to the stage truss that was left in place even though the weight of the tops was fully on the subs.

I never did figure out if that was just one providers technique that I would see in a number of towns,or a common technique. Honestly in those days I was semi retired from sound and was more interested in trout fishing

I've been occasionally pondering the same thing myself since it's likely my next speaker purchase will push me over the logistical edge to need some sort of lifting device if ground stacking.  Global Industrial seems to have some interesting solutions that might work depending on how high and heavy you need to lift.

. . . in the 4-6ft height range. . .

Easiest way I have found to do this:

1) Set up the top cabinet in front of the subs, correctly oriented
2) Have one guy on each side of the top box, facing the sub stack grab the upper side handle of the top cabinet with their closest hand
3) With other hand, grab lower handle OR place hand low on front of top cabinet
4) Lift and rotate the top cabinet so that the front of the cabinet is facing down
5) Set the bottom front edge of the top cabinet on top of the stack
6) Walk the top cabinet up into position
7) Using the reverse of this method to get speakers down at the end of the night may require someone standing on top of subs to help lower speaker to handlers

Also works for loading the truck when the lift gate breaks or when some idiot bends the ramp up jamming it in after the last stop.
