Rolling Metal Scaffolding with Crane

[NeiljohnUK]

Many A-frames don't take moving under load kindly, but can't dispute this works. Actual load weight is one factor, load height [CG], position within footprint of casters, and load balance. I'm certain doubled bracing on the same side might be more instrumental than apparent, along with combined outrigger-brakes, unloading the casters.
Good job, moving heavy parts single-handed is frequent issue.

I had to investigate a minor injury/near miss involving a runway beam A frame being pushed along with a suspended load failing some years ago. 2 tonne's of stainless steel cactus sculpture covered with sharp steak knives scratched one s-too-dense arm as it fell, the runway bean narrowly missed another, what use their safety boots and rigger gloves would have been if either item had fallen directly on them was questionable. They started out lifting, running the beam, lowering, then reposition and repeat, but as it was taking too long to move ~30 yards the leading Academic decided to push the frame along, it caught a tiny floor defect and the momentum was enough to snap all the high tensile bolts holding it together. Never under estimate the kinetic energy of a swinging load!
