Drop Down Bumper Assembly - Efco SWAPLOADER SL-412 Parts And Operation Manual

INSTALLATION INSTRUCTIONS – DROP DOWN BUMPER ASSEMBLY
1. Review all directions and diagrams provided before starting bumper installation. Typically, a
drop down bumper is needed when the rear of the container extends beyond the back of the
truck such that the distance between the truck bumper and container rear exceeds 24" (see
Fig. A). Office of Motor Carrier Safety (OMCS) Regulation 393.86 requires that no bumper
be located more than 30" off the ground when the truck is empty, and the end of the bumper
should not be located
more than 24" from the
extreme rear of the
vehicle, including truck
bodies (see Fig. A).
2. Position drop down
bumper on the longsills of
the sub-frame (see Fig. B
& C). The mount brackets
(Pt. No. 51H17) need to
be positioned correctly to
allow for sufficient room
for bumper cradles (Pt.
No. 51H19) (see Fig. B).
Weld mount brackets onto
the longsills of the sub-
frame.
3. Position bumper cradles (Pt. No. 51H19) on
the longsills of the sub-frame. Check
bumper cradles for squareness with respect
to each other. The bumper tube (Pt. No.
51H16) should come to rest within the
bumper cradles when the container rests on
the ground (see Fig. B & C). Weld bumper
cradles into place on longsills.
