See Table 1. 4.2.3 Tests 2, 3, 4 and 5 The truck shall be positioned on the tilt table with the line, M—N, parallel to the tilt axis, X—Y, of the tilt table. See Table 1. In all positions, the castor wheel(s) shall be turned away from X-Y to the orientation that produces minimum stability. Point M is the point located on the drive/steer axle end of the truck and defined as follows. a) For trucks with a single drive (steer) wheel: point M shall...
