Crappily Designed Devices

I'm watching two guys traverse down the face of a skyscaper across Mission street. They don't seem to be washing the windows, but inspecting the facade of the building. The facade is composed of flesh colored panels 2x4' or so. It makes me wonder if I should walk under than building: are they in danger of falling off?

Moreso though, another project pops into my head, someone should really redesign those window-washing elevater devices. To lower or raise the platform, both men have to lower or raise their end. These two could never get the platform level, and it looked like there was a constant rocking motion, which can't be good for the cranks up top, nor the wires.

Perhaps, it is to make sure that the men are balancing it as they move up or down.
