See Table 1.4.2.3 Tests 3, 4 and 5The truck shall be positioned on the tilt table with the line, MN, parallel to the tilt axis, XY,
27、of the tilt table. See Table 1.Point M is defined as follows.a) For trucks with a single non-articulating drive (steer) wheel: point M shall be the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centreline of the drive whee

37、s the centre point of the area of contact between the tilt table surface and the load front wheel closest to the tilt axis, XY, of the tilt table.4.3 Datum point positions4.3.1 GeneralTest 1 may be conducted with the horizontal position of the load datum point, E, unchanged when elevated from its lo
38、wered 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 h
39、aving 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 origina
40、l location of F, as shown in Figure 2 e) and f).For trucks with tilting masts, changes in the location of F1may 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 F1is subje
41、ct to regional requirements.4.3.2 Regional requirements for trucks with non-tilting masts4.3.2.1 North America and AustraliaThe location of F1shall not be corrected. Only correction by varying the mast tilt is permissible.4.3.2.2 All other regionsAdjustments in the fork arms or fork carrier tilt, fo
42、rk carrier retraction (where provided) or retraction of the mast may be used to correct for changes in the location of point F1, within the limits provided by the design of the truck.
