It is a kind of whippletree, and the term is also used sometimes for other whippletrees.
The swingletree is a horizontal bar, attached or suspended in the middle, and able to pivot in a horizontal plane. The traces (the straps by which the horse pulls the load) attach to the ends of the swingletree, and the load is pulled from the centre point.
