BS ISO 22915-15 This document specifies the tests for verifying the stability of counterbalanced fork-lift trucks with articulating steering and with mast, equipped with fork arms or load-handling attachments.It is not applicable to trucks with retractable devices such as a retractable mast or fork.The lateral stability tests according to Table 1 shall be conducted on the side of the truck which is the least stable.The truck shall be positioned on the tilt table at maximum articulation with line M-N parallel to X-Y (see Table 1).Point M is defined as the centre point of the area of contact between the tilt table surface and the rear wheel nearest to the tilt axis, X-Y, of the tilt table.Point N is defined as the centre point of the area of contact between the tilt table surface and the load wheel nearest to the tilt axis, X-Y, of the tilt table.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. 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 b). This new point may be returned to the original location of F, as shown in Figure 2 C), by varying the tilt of the mast within the limits provided by the design of the truck.BS ISO 22915-15 pdf downlaod.
