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.
Nice build that has multi-functional capability.
One feature I really like is the LED UFO light mounted above the scaffolding on what appears to be a swing arm
I can not even count the times I had wished there had been a work light on an A frame crane I was using when trying to pull and engine or set a machine in place

No matter how many lights you install, you'll still resort to using a flashlight at some point.Quote:

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!Quote:

NeilJohnUK commented also "what use their safety boots and rigger gloves would have been if either item had fallen directly on them was questionable". News report, bodies smashed beyond recognition, but authorities ID'ed via fingerprints of one, bunions and gout of the other.
Fine arts and sculpture. H&S doesn't register with them, nor do they have any understanding of lifting equipment use or maintenance, that's somebody elses job...Quote:

I did use a less drastic version mentoring high school engineering (machining) students.
Subject was clamping work to mill. Demonstrated clearly and verbally how to position stud to apply sufficient pressure, including leverage often. Well, they head for mill tables and start threading fasteners together, straps and step blocks. Most bolts unevenly placed, many bearing on step block........grrrr. I signaled worst offenders over to best (barely) example. "Set your finger on the table, and another this far away" Took lead pencil out of my pocket, laid it over both fingers and pressed in the middle; no reaction. Moved my finger far enough to put majority on his digit and pressed (with a bit more, for insurance, lol).
Instantaneous Ouch and look of surprise!
I'll bet he never forgets.
