[SML] sprung floor load capacity???

[Bill Conner]

> We've got sprung floors here in all our performance spaces.   True 3 layer basket weave in some and ply on sleepers on pads in others.   University facilities is doing some work over the summer.  There is talk of using a self propelled genie scissors lift---older unit but pretty much a GS 3232 which has a weight of 5185 lbs.  and a 32' platform height.

Hard to say.  Possible they can hold a fork truck with correct
construction.  Pretty sure our standard does - 1 1/8" ply on 2X4
sleepers on 16" centers with stopper blocks (anti-deflection) 24" on
center on the sleepers. We sometimes allow double 3/4" ply on 12"
centers. I would just assume it would deflect the resilient pad the
max.  An engineer can calculate the system if you know the details.

I would guess you are right about basket weave depending on spacing
and sub floor material.

A single floor for ballet dancers en pointe and for trucks is tough
