Always ratchet strap the cabinet to the hand truck. That's key.
And arcade machines are way heavier than pins, so I consider move a pin up and down stairs fairly easy. My X-Arcade "mame" cabinet I am selling weighs 480lbs! That was not fun getting it out of the seller's home. Didn't come out of a basement, but the second floor of a split level house. 6 steps down out of the living room to a tight landing, then 13 steps down out of the house. Ugh.
