4.5.2 Tests.
4.5.2.1 Operational. The loading plates shall be positioned with a height
differential of zero inch and 6 inches with the railcar or truck end at the
higher level. The span opening shall be 2 inches or less for types I and III
loading plates and 10 inches, 26 inches, and 42 inches for type II loading
plates, when lifting loops are specified, and style B loading plates shall be
lifted, transported and positioned, utilizing the lifting loops, by a forklift
truck having forks 36-inches long, 6-inches wide and located on 24-inch centers.
At each height position with each span opening, a forklift truck having a gross
vehicle weight (GVW) of 15,000 pounds shall be driven forward across the plate
from the dock to the railcar or truck and then backward from railcar or truck
to the dock. Nonconformance to 3.4.2, 3.4.3, 3.4.6, and 3.4.7 as applicable,
or evidence of instability shall constitute failure of the plate.
4.5.2.2 Static load. The loading plate shall be placed over a span of
not less than 20 inches for type I and not less than 42 inches for type II
loading plate. Type III loading plate shall be placed over a span of not
less than 20 inches across the dockboard section. The platform end and the
truck or railcar end shall be supported at the same height. The loading
plate shall be subjected to a static load of 30,000 pounds applied over an
area extending not more than 2 inches on each side of the transverse center-
line of the loading plate for the full width of the loading plate. The load
shall remain on the loading plate for a period of 30 minutes, after which the
load shall be removed and the loading plate shall be inspected. Evidence of
permanent deformation, weld failure or damage shall constitute failure of
this test. During this overload test the loading plate shall be supported as
during normal use.
4.5.2.3 Lifting loops. Lifting loops, when provided, shall be tested
as follows. The loading plate shall be supported by a 4 inch wide forklift
tine or equivalent support member through each lifting loop. The support
members shall be located centrally within the lifting loops. The dock
board shall be loaded with twice the weight of the loading plate while being
supported as described above. This overload shall remain for 5 minutes.
Permanent deformation, weld failure, or damage of any kind shall constitute
failure of this test.
