Cart Lifter
®
When the mounting height is
determined, the lifter's
mounting plate frequently ends
up being higher than the
original load sill. This is normal
and requires the addition of a
supporting structure.
It is necessary to fully support
the mounting plate to provide a
rigid base for the cart lifter. An
unsupported mounting plate
can easily deform through
normal use in a short period of
time. Failure to fully support
the mounting plate can lead to
rapid premature failure of the
cart lifter.
Perkins recommends adding
steel structural tube across the
entire length of the load sill.
This tube becomes the new load
sill.
The tube should be at least ¼"
thick, and sized to allow the top
of the support to mate to the
top of the mounting plate. Do
not extend the support tube
above the mounting plate top
edge.
The size needed will vary from
installation to installation, use
what best suits your needs.
Note: Simply adding gussets to
the back of the mounting plate
does not provide adequate
support. The reinforcement should
cover the entire rear of the plate
and be welded fully.
