Les bras sont montés sur le mécanisme rotatif et peuvent se mettre en rotation entre une position libre et une position restreinte. Les bras dans la position restreinte s'étendent autour de la roue avec chaque face de limitation de course faisant face aux côtés d'au moins une partie de la roue et empêchant ainsi la direction de la roue. Les bras dans la position libre s'étendent à l'opposé de la roue et n'empêchent ainsi pas la direction de la roue.
