Also, I'm having difficulty picturing your proposed solution. Specifically how you get the idler out of the way of the crossbar. If the idler is behind the crossbar, you'd have to move it outwards to disengage the pole, then sideways to clear the bar. Unless an idler is actually two idlers that come in from opposite sides and wrap around the pipe to keep you from sliding off sideways or something.

While I haven't looked into the specific engineering yet, I was envisioning 4 pneumatic cylinders, two on each side, and actuating at a diagonal. When they would move back, they would both retract from the diagonal, and clear the crossbar.
