That's the main reason you should never, ever, ship games standing up on their legs!!! They should always be blanketed and wrapped and strapped to a pallet. Sure, they can damage it that way, too, but it's much less likely.
I will move a pinball machine with a pinjack across a room, but if it's going to another floor or another location, the legs come off and it gets dollied around safely and securely.
I have several games including a TZ and a Road Show that both need new leg reinforcing plates because the old ones are all stripped out from the previous owners MOVING THE GAMES ON THEIR LEGS!!!
I think that's also the main reason cabinets split at the corners, on newer and older games. Nobody tilts games hard enough to do that kind of damage. It happens because the game was moved around everywhere with its legs on.
Friends don't let friends ship pinball machines with the legs on!
