normal operating conditions
operating conditions corresponding to the truck travelling indoors on smooth, level floors of sufficient strength such as those of concrete
Note 1 to entry: This definition is different from the one given for normal operating conditions in ISO 22915-1.
steering mode, either mechanical (e.g. guidance rails) or non-mechanical (e.g. inductive guidance, laser sensor or infrared) not controlled directly by the operator, used to steer the truck on a predetermined straight path while travelling
operation under which the truck’s steering is controlled by the operator and the steering angle is limited to not more than 100 from the forward or reverse travel direction
steering mode controlled by the operator with no limitation of the steering angle
4.2.2 Tests 1
The truck shall be positioned on the tilt table so that its drive/steer axle, B—B, and load axle, C—C, are
parallel to the tilt axis, X—Y, of the tilt table. See Table 1.
4.2.3 Tests 2, 3, 4 and 5
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. See Table 1.
In all positions, the castor wheel(s) shall be turned away from X-Y to the orientation that produces minimum stability.
Point M is the point located on the drive/steer axle end of the truck and defined as follows.
a) For trucks with a single 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 wheel width.
b) For trucks with a drive/steer axle in an articulating frame articulated in the centre plane of the truck: point M shall be the vertical projection onto the tilt table of the point of intersection between the lateral axis of the articulating frame and the centre plane, A—A, of the truck.
c) For trucks with dual drive (steer) wheels: point M shall he the vertical projection onto the tilt table of the point of intersection between the centreline of the drive/steer axle and the centre plane, A—A, of the truck.AS ISO 22915.21 pdf download.
