Division 1.3.1 The tractor shall be so placed in relation to the weight that the weight will strike the roll-over protection structure when the impact face of the weight and the supporting chains or wire ropes are vertical unless the protection structure at the point of contact is, during deflection, other than vertical. In this case the impact face of the weight shall be adjusted by means of an additional support so that it is parallel to the protection structure at the point of impact at the moment of maximum deflection, the supporting chains or wire ropes remaining vertical. The suspended height of the weight shall be so adjusted that the locus of its centre of gravity passes through the point of contact.F1
