This Wenger Drum Major Podium is a beast. It's a heavy duty rolling steel cart with a platform that elevates to 6 ft. Designed for field performances, it's meant to be quickly rolled out onto a field and easily set up/taken down. A wide base, 2 locking casters, and quick-to-install guard rails keep this safe and stable enough for all sorts of active use (we tested with a short dance number). It would certainly be handy as construction or film production scaffolding. These retail for $4400 new, see more details here. This one has a slightly bent ladder, price reflects.

Stored platform height: 21.25 Raised platform height: 72.5 Rails add 38" to height when installed.
