Mechanical “Beanstalk” (Aug, 1950)

That thing looks a little unstable to me…

Mechanical “Beanstalk”
Work at a height of 22 feet is easily-reached by a mobile hydraulic platform. The user operates’ a manual hydraulic pump that boosts the tubular-steel platform to its maximum altitude in two minutes. It is lowered by pulling a pressure release. Four screw jacks lift the equipment off its rubber-tired casters and hold it in position during use. The complete unit can be folded to permit passage through a doorway six feet six inches high and less than 2-1/2 feet wide.
