e. Loading/Unloading a Scissored Bridge to/from a Lowbed or Flatbed Semitrailer using forklifts -
(c) With the folded bridge raised off the ground, back the trailer slowly underneath the folded
bridge so that the bridge may be laid flat and centered on the trailer. Position two timbers fore
and aft on the bed of the trailer, so that the bridge will be raised off the trailer bed only enough
to allow the forks to be retracted from underneath. The size of the timbers should be
approximately 8" x 8" x 8' long and placed across the trailer bed, 3-4 feet in from each end of
the bridge. The timber needs to be 8" wide x 8" high because the decking of the bridge will
rest on it and there needs to be ample room underneath for the forks to be inserted and/or
retracted easily. If necessary, carefully jockey the bridge so that it is centered on the trailer.
The tractor should be kept hooked-up to the trailer to prevent any movement of the trailer
from occurring. There is no need to chock the rear duels of the trailer, unless the tractor is
removed. When loading onto the lowed/flatbed semitrailer, care should be taken to keep the
quadrant clear of the gooseneck of the lowed or the vertical head board of the flatbed trailer to
avoid any damage.
(d) Once the bridge is in position aboard the trailer, it should be secured IAW applicable
When securing the bridge to the trailer, DO NOT pass the steel chains through the
aluminum pin holes of the center hinges or connectors. If this is done, damage to the
aluminum pin holes will result, rendering the bridge inoperable.
(2) Unloading. This operation is essentially the reverse of the loading operation, above.
Prior to releasing and removing the tiedown chains from the bridge/trailer, the forklifts
should be in position along each side of the bridge with forks cradled underneath the
bridge to prevent the bridge from slipping or shifting its position.
When releasing the tie down chain binders use extreme caution to avoid binder handle
backlash which may likely occur.
(a) Position two forklifts on each side of the folded bridge on the semitrailer, spread and center
the forks on the black vertical lines painted on the sides of the sections (Class 70) or bridge
