Once upon a time there was this twenty four foot long piece of six inch schedule forty pipe that wanted more than anything else to be a cross bar over an entry way.
All that separated it from this lofty goal was, well, just sixteen and a half feet. It needed an elevator.
First a Ford 540 tried to be enough elevator for the job. Then a Cat 953 crawler loader tried. Neither could, just not enough, well, elevating ability.
Enter Iris, a little small as far as elevators go, but a lot of heart. /forums/images/graemlins/smile.gif
