The car mover gets a good work-out if the crew doesn't spot the car exactly right on the lift. Our car lifts have a small area to lift on the carbody so fine adjustments are routine at Overbrook Shop on Septa. Newbies are flabbergasted that one person can move a married pair set with a pry bar!
Some time the car puller overshoots the wheel truing machine and the car has to be moved a foot or so back, the car jack does the job. I never tried that with an AEM-7, at 202,000lbs. thats too much for me
