●
The socket-head cap screws must be long enough to pass
through the safety hook, patient compartment floor, both
washers,
and
still have at least two full threads extending
past the nut.
●
The hardware should be of at least SAE Grade 5 with UNC-2
threading (or equivalent).
PROPER SAFETY HOOK PLACEMENT
Position the safety hook as close to the rear of the ambulance
as possible, within the limits below:
●
The bumper or extended folding bumper must not
exceed 14 inches (356 mm).
●
Position the safety hook with the hook facing the front
of the ambulance.
●
Position the safety hook at least 11 inches (279 mm)
from both sides of the door frame (Figure 3) so the cot
safety bar will engage the hook when the cot is loaded
or unloaded.
●
Position the safety hook no more than
19-7/8 inches (505 mm) from the front edge of the
hook to the rear of the ambulance,
including
the
bumper and folding bumper step in the extended
(open) position.
INSTALLING THE SAFETY HOOK
1.
Mark the position of the safety hook on the floor.
2. Drill holes for the screws and attach the safety hook to
the floor (Figure 4).
3. To test the hook, load and unload the cot. Verify that
there is no interference with folding or unfolding
the legs.
Important
If the safety hook is installed too far inside the
ambulance, you will not be able to properly fold or
unfold the cot undercarriage when it is secured by the
hook. Measure and install the safety hook as instructed
in this manual.
