Kino sled
From The Stargate Omnipedia
Makeshift levitating platform invented by Eli Wallace to help transport heavy objects over distances. The sled has the surface area of a small table, and is large enough for a man to lie on.
It was invented by placing several kinos underneath a tabletop, and (most likely) linking together all of their navigation to a single remote.
