Have help. Leave in box. Truck the side that says truck this side only. Put help you don't care that much about on the heavy end going down. Just in case.

LTG : )

Agree with LTG, if you can leave it in the box, do so.

Be patient, and take it one step at a time.

Have some helpers and take your time. Good luck with TNA!!

I've wondered how feasible it would be to leave a pin in the box and then slide it down the stairs while you walk in front of it backwards, holding onto it to control its speed. Or will that end up with a giant box crashing to the bottom of the stairs and you looking like a flattened Wile E. Coyote with a box imprint on your face?

Control slide in box with this end up should work. Biggest helper work the bottom. Enjoy

I have done this several times, and it works just fine...especially with stairs that have a tight 90 degree turn at the bottom.

Do this, but beforehand definitely make sure the width of the box will FIT through a doorway if there's a door near the stairs. Measure with tape measure, and check the top and bottom of door frame to ensure. If the door can't open completely to get out of the way, you need to account for it (or hinges) that also obstruct.

You don't want to get 3/4 down the stairs and realize you have to bring it back up. I even know someone that has to remove his door frame each time a certain backbox width has to be moved. Always measure out the entire path before you're putting 250lbs on stairs.

It depends on size of your basement staircase, if it is an average size staircase and has any turns-it will be difficult to get downstairs in the box. I once got a machine stuck halfway down the stairs while in the box. The way I move my machines into basement: I open in garage and have a friend help me lift onto pinball cart and remove packaging, strapping, and leg bolts. I then have another cart placed in basement to put machine on when we get to basement. We then put on some good grip gloves and essentially just lift and carry the machine down the stairs going very slow through doorways to make sure not to scratch backbox. I have tried dolly's, etc. and find they are not as easy as just carrying the pin down the stairs. I am a bigger guy and have some strong friends-so I guess that helps.
