I'm no Hercules, but I rotate the monitor of my NNC standing up alone, and it's heavier than the Blast City monitor.Hats off to the person that can lift the monitor out with those bars with the cab standing up.
The weight alone is not the issue. The issue is the weight + lack of place for your hands + the very narrow space to manovre that will result in scratching your fingers or the cab's paint with the sharp edges of the frame + the stupid precise precision you have to put it in to fit de D shape holes.
The handle bars would solve only one part of the issue. Clearly not a magic trickand you'd have to take the time to screw them in place before use, and remove them afterwards.
