4.7.2.3 Maximum fork height. With no load and mast in the true vertical
position, measure and record the maximum fork height. Nonconformance to the
applicable specification sheet shall be cause for rejection.
4.7.2.4 Free lift height. With no load and mast in the true vertical
position, measure and record the free lift height. Nonconformance to the
applicable specification sheet shall be cause for rejection.
4.7.2.5 Drift. Start the truck and allow the hydraulic system oil to reach
normal operating temperature. Position truck on a level surface and raise the
rated load to the maximum lift height with uprights in a true vertical
position. Immediately mark a reference point on upright. After 10 minutes
record vertical and rotational drift. Nonconformance to 3.6.5 shall
constitute failure of this test.
4.7.2.6 Sideshift. Sideshift level forks to extreme left position. Note
and measure any increase in truck width and whether there are any protrusions
beyond the sideshift carriage. Sideshift forks to extreme right position.
Measure sideshift travel. Note and measure any increase in truck width and
whether there are any protruaions beyond the sideshift carriage.
Nonconformance to 3.6.6 shall constitute failure of this test.
4.7.2.7 Fork size and spacing. Measure and record fork size and spacing.
Nonconformance to the applicable specification sheets shall be cause for
rejection.
4.7.2.8 Lifting speed and lowering speed. Measure and record distance in
inches from floor to top surface of forks in fully lowered position. Record
time in seconds required to raise capacity load to maximum fork height using a
timing device. Record the difference between maximum fork height and the
height of the forks in the lowered position. Record time in seconds to lower
capacity load at maximum speed (full open valve) to 3 or 4 foot height, load
to be abruptly stopped at the 3 to 4 foot height. Repeat the raising and
lowering three times. Raise capacity load to maximum height and simulate hose
failure to demonstrate conformance to 3.13. Remove load and raise empty forks
to maximum lift height. Record time in seconds required to lower forks to
lowered position. Nonconformance to 3.6.8 or 3.6.9 shall be cause for
rejection.
4.7.2.9 Right angle turn. With capacity load on forks raised 6 inches
above ground, demonstrate in accordance with test method 3 that the truck can
meet the right angle turn dimension as specified on the applicable
specification sheet. Nonconformance to 3.6.10 shall be cause for rejection.
4.7.2.10 Slope ascension. Drive truck forward with capacity load along a
horizontal approach and onto a ramp or slope of specified grade and bring to a
complete stop. Apply parking brake to see if brake holds on slope, release
parking brake. Start from a dead stop and proceed up the ramp to a horizontal
surface. Remove capacity load and repeat above test. Nonconformance to
3.6.11 shall be cause for rejection.
