See Table 1. 4.2.3 Test3and4 The truck shall be positioned on the tilt table in a turning position with the line, M—N, parallel to the tilt axis, X—Y, of the tilt table. As shown in Table 1, the steered wheel nearest to the tilt axis shall be parallel to X—Y. Point M is defined as follows. a) For trucks having an articulating steer axle: point M shall be the projection on the tilt table of the intersection of the longitudinal centre-plane, A—A, of the truck with the axis of this axle. b) For trucks steered by a single wheel: point M shall be the centre point of the tread contact area between the steered wheel and the tilt table surface. c) For trucks steered by twin wheels: point M shall be the centre point of the tread contact area between the steered wheel closest to the tilt axis, X—Y, of the tilt table and...
