g) For trucks with a non-articulated, single-drive wheel (steered) on the centre plane. A-A, and sprung castor wheels point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive wheel axle and the centreline of the drive wheel width, with the axle of the drive wheel positioned at right angles to the tilt axis. The castor wheel closest to the tilt axis shall he positioned at right angles to the tilt axis and the castor wheel axle shall be nearer to the centre plane of the truck.
As shown in Table 1, point N is defined as the centre point of the area of contact between the tilt table surface and the load front wheel closest to the tilt axis X—Y, of the tilt table.
4.3 Datum point positions
4.3.1 General
Test I may be conducted with the horizontal position of the load datum point, E, unchanged when elevated from its lowered position as shown in Figure 2.
With the prescribed test load, set the mast vertical and then elevate to approximately 300 mm above the tilt table. With the shank of the front face of the fork arm set vertical, establish point E, as shown in Figure 2 a) and b), on the fork arms or fork carrier having a fixed relationship to the centre of gravity of the test load. Point E shall be used to provide a reference datum point, F, on the tilt table. When the mast Is elevated, a new point, F1, on the tilt table may occur, as shown In Figure 2 c) and d). This new point may be returned to the original location ofF, as shown in Figure 2 e) and 1).
For trucks with tilting masts, changes in the location of F1 may be corrected by varying the tilt of the mast within the limits provided by the design of the truck. See Figure 2 a), c) and e).
For trucks with non-tilting masts, the location of F1 is subject to regional requirements.
4.3.2 Regional requirements for trucks with non-tilting masts
4.3.2.1 North America and Australia
The location ofF1 shall not be corrected. Only correction by varying the mast tilt is permissible.
