It provides a wheel v a pole attached in the center as one axle to help it come lift or relocate loads. In some cases this an equipment works choose a bar to multiply force (like v a doorknob or a fishing reel). In other situations it is supplied to move objects easier such similar to wheels top top a bicycle.
