The vehicle safety hook is a device shipped with the
cot. The safety hook activates the safety bar and
prevents the cot from being removed from the vehicle
accidently. The vehicle safety hook was designed to
ensure compatibility and proper operation of the cot
during unloading when used in an ambulance vehicle
compliant with Federal Regulation KKK-A-1822.
According to federal regulations (reference KKK-
A-1822), the bumper height of the ambulance shall
be installed equidistant
5 cm (2 inches) from the
±
ambulance floor to the ground level, defined as the
ambulance deck height (Figure 9). The bumper step
shall have a minimum depth of 13 cm (5 inches) and
a maximum depth of 25 cm (10 inches). If the bumper
depth is greater than 18 cm (7 inches), then the
bumper must be able to fold. Installation of the safety
hook into any ambulance vehicle compliant with this
federal specification will provide adequate clearance
for the cot base to lower to its fully extended position
(Figure 10). The cot is compatible with all ambulance
deck heights up to 36 inches (91 cm) as long as the
ambulance meets the federal specifications outlined
in KKK-A-1822.
CAUTION
Set cot height limit to the proper stop height (see
page 18) prior to operation.
Installation of the safety hook should be done
by a certified mechanic familiar with ambulance
construction. Consult the vehicle manufacturer before
installing the safety hook and be sure the installation
of the safety hook does not damage or interfere with
the brake lines, oxygen lines, fuel lines, fuel tank or
electrical wiring of the vehicle.
WARNING
Have the vehicle safety hook installed by a certified
mechanic. Improper safety hook installation can cause
injury to the patient and/or operator or damage to the
cot.
Failure to install the safety hook can cause injury to
the patient or operator. Install and use the safety hook
as described in this manual.
To avoid injury, verify the safety bar has engaged the
safety hook before removing the cot from the patient
compartment.
