2) the vertical projection onto the tilt table of the point of intersection between the centreline of the castor wheel width, with the non-sprung castor positioned so that the centreline of the castor wheel axle is parallel to and further away from X—Y.
g) For trucks with a non-articulated, single drive wheel (steered) on the centre plane, A—A, and having 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 X—Y. The castor wheel axle closest to X—Y shall be positioned parallel to and further away from X—Y.
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 1 shall 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), 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, F.1, on the tilt table may occur, as shown in Figure 2 b). This new point may be returned to the original location of F, as shown in Figure 2 c).
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, as shown in Figure 2.
For trucks with non-tilting masts, the location of F1 may be returned to the original location of F by adjusting the fork arms or fork carrier within the limits provided by the design of the truck.
In the ‘Test 7’ column heading, add a reference to footnote “h, so that the heading reads “Test 7 e, f h”,
In the “Test 9” column heading, replace the reference to footnote “b by a reference to footnote “1”, so that the heading reads Test 9 e. f. h”•
In the “Lift height”,’“Travel” line, ‘Test 9column, delete the “X” and replace it by footnote reference g.
In the “Tilt table angle” line containing an explanation of symbols I and v, replace “v is the maximum travel speed of the unladen truck, in km/b” by “v is the maximum travel speed of the truck (unladen or laden with the actual load), in km/h.”
