(2) Place a 6000 pound load on the forks with the center of mass
of the load on the longitudinal centerline of the mast which
shall be on the longitudinal centerline of the truck with
the forks in the front carry mode. Pivot and side shift the
load to the position of least lateral stability. Elevate
the load approximately 12 inches above the platform and
position mast in true vertical position using level and
plumb bob, or equivalent.
(3) With the load elevated to maximum height, and the mast
repositioned to true vertical, the test platform shall be
tipped to a 6 percent slope. During the test there should
be no operator on the truck. Maintain the truck position on
the platform by brakes or other similar means, but not by
means of wheel chocks.
(4) Repeat test (c) using left load wheel in lieu of right load
wheel.
(d)
Lateral Stability - Traveling
(1) Placement of Truck
a.
Place empty truck with an articulated steer axle, on an
initially level platform in a position that a line
connecting the center of the left load wheel tire (or
outermost tire where multiple tires are used) and the
projection perpendicular to platform of the point of
intersection of the longitudinal centerline of the truck
and the centerline of the steering wheels is parallel to
the axis of the tilting of the platform. Steering
wheels shall be positioned such that they are parallel
to the tilt axis of the platform (see Figure A-10).
b.
Place empty truck, with a nonarticulated steer axle, on
an initially level platform in a position that a line
connecting the center of the left load wheel tire (or
outermost tire where multiple tires are used) and the
projection perpendicular to the platform of the point of
intersection of the respective steer tire centerline is
parallel to the axis of the tilting platform. Steering
wheels shall be positioned such that they are parallel
to the tilting axis of the platform (see Figure A-11).
(2) Place a 6000 pound load on the forks and pivot the load 90
degrees from the longitudinal centerline of the chassis and
shift to the position of least stability. If the truck has
a tilting mast, the mast shall be either vertical or at full
rearward tilt, whichever is less stable. Elevate the forks
until the point of intersection of the front vertical face
and top surface of the forks are 12 inches from the floor.
(3) Tip the platform to the minimum slope specified in ANSI
B56.1. During the test there shall be no operator on the
truck. Maintain the truck position on the platform by
