That's the best picture I could find of one. That's a little one. The idea is that there's a pole attached to the overhead wire by a big spring. The bottom of the pole is curved and has a small round "seat." You grab the thing, place the roung seat under your legs, and it pulls you forward. The big spring is so that it doesn't lift you off the ground as the terrain changes under you, but it also has the effect of launching you a little bit right at the beginning.
A detatchable one has an especially large "launch" at the beginning. All sorts of fun.
