ISO 22915-5:2014 pdf free.Industrial trucks – Verification of stability
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.
Point N is the centre point of the area of contact between the tilt table surface and a non-articulating wheel or stabilizer pad. Point M is defined as follows.
a) For trucks with an articulating steer axle, B-B, designed to articulate approximately about the longitudinal centre plane of the truck, A-A, the projection onto the tilt table of the point of intersection of the longitudinal centre plane of the truck with the axis of this articulating axle, see Eigure 1.
b) For trucks without an articulating axle or with axle locks or stabilizers in use, the centre point of the area of contact between the tilt table surface and another wheel or stabilizer pad.
When the truck rating is related to the use of stabilizers, suspension locks, etc, such devices shall be used during the tests. If the truck can be used without their engagement, an additional test shall be carried out in this condition.
Tests 1 and 5 shall be conducted with the horizontal position of the load datum point, E, see Figures 2, 3,and 4, unchanged when elevated from its lowered position.
By means of a plumb-line or other suitable equipment, set the mast vertical. Elevate the fork and the prescribed test load to approximately 300 mm above the tilt table. With the front face of the fork arm shank vertical, establish a point, E, on the fork 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 daturm, F, on the tilt table. When the mast is elevated, a new point, F1, on the tilt table may occur, as shown in Figure 3. By the following adjustments this new point, F1, can be returned to the original location of F.
For trucks with tiltable masts, changes in the location of F1 shall be corrected by varying the tilt of the mast within the limits provided by the design of the truck.
Adjustments cannot be made on trucks having non-tiltable masts, or fork carrier. Mast retraction is not permitted.ISO 22915-5 pdf download.
