Division 1.2 Impact at the frontF1

United Kingdom Repealed

1. 1.2.1The 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 at an angle of 20 ° to the vertical unless the roll-over protection structure at the point of contact has, during deflection, a greater angle to the 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 roll-over protection structure at the point of impact at the moment of maximum deflection, the supporting chains or wire ropes remaining at an angle of 20 ° to the vertical. Steps must be taken to reduce the tendency of the weight to turn about the point of contact. The suspended height of the weight shall be so adjusted that the locus of its centre of gravity passes through the point of contact.
2. 1.2.2Tractors with rigid bodies shall be lashed down as illustrated in Annex IV, fig. 6. The points of attachment of the lashings shall be approximately 2 m behind the rear axle and 1,5 m in front of the front axle.
3. 1.2.3Division 1.2.3
4. 1.2.4The weight shall be pulled back so that the height of its centre of gravity above that at the point of impact is given by the formula:
