Quoted from pinnaf:1 person high, 1 person low (2 low is crowded), stair climber appliance dolly, STRAP around pin and secure strap directly to the dolly. I have done this many times and its the BEST way. Going to the gym everyday and getting on the "back" machine doesnt hurt either!
good luck my friend
Thats methods works good for me to ,just make sure your belts turn freely and the smaller wheels seem to work the best
