I'd call that a tripod, Shear legs are an A-frame, where you lean them at an angle and attach the load to the apex, anchor the bottoms of the legs and pull the whole thing upright. The load rises and swings inward. Or: the frame is secured at an angle and a pulley at the top is used to lift the load.I'm probably wrong but I think the salient point is directing the force down the angled legs.
Sorry, but I'm using the wonderful innovation of the broad band enabled pub to write this!
