Chapter 10 – Stowing and Transporting

Use a winch to load and unload the aerial platform on
ramps that exceed a 25 percent grade. A 25 percent grade
is a 0.76 m (30
″
) vertical rise in 3.05 m (10
′
) horizontal
length. A winch may also be used when poor traction,
uneven surfaces, or stepped ramp transitions make driv-
ing hazardous.
Drive the aerial platform onto the transport vehicle if a
winch is not available and the ramp incline is within the
25 percent grade capability of the aerial platform.
Use the following procedure to drive the aerial platform
onto the transport vehicle.
1. Position the transport vehicle so the aerial platform
will not roll forward after it is loaded.
2. Chock the vehicle wheels so it cannot roll away from
the ramp while the aerial platform is loaded.
3. Remove any unnecessary tools, materials, or other
loose objects from the platform.
4. Retract the platform extension deck and ensure both
lock pins are engaged in the holes with the handles
angled upward. Fully lower the platform.
A
Caution
The extension deck is free to move when the pins
are disengaged. Make certain the pin is engaged
when the deck is extended in the working position
and when it is stowed.
5. Drive the aerial platform to the foot of the loading
ramp with the front wheels nearest the ramp. Make
sure the aerial platform is centered with the ramps
and that the steering wheels are straight.
6. Place the drive range switch in low (turtle) for climb-
ing or descending a ramp.
7. Drive the aerial platform on or off the transport vehicle
in a straight line through the grade transitions with
minimal turning.
Hoisting
Use a four point sling arrangement attached to the lifting
lugs when hoisting the aerial platform. Machine damage
can occur if the sling is attached to the chassis, scis-
sors structure, or platform.
A
Warning
The potential for an accident increases when the
aerial platform is lifted using improper equipment
and/or lifting techniques. Death or serious injury can
result from such accidents. Use proper equipment
and lifting techniques when lifting the aerial plat-
form.
Know the weight of the aerial platform and the capacity of
the lifting devices before hoisting. Lifting devices include
the hoist or crane, chains, straps, cables, hooks, sheaves,
shackles, slings, and other hardware used to support the
machine. The gross vehicle weight is stamped on the
serial number placard and is listed in Chapter 2.
The user assumes all responsibility for making sure the
equipment used is capable of supporting the weight of
the aerial platform and that all manufacturer’s instruc-
tions and warnings, regulations and safety rules of their
employer and/or any state or federal law are followed.
Use the following procedure to hoist the aerial platform
onto the transport vehicle.
1. Properly stow the aerial platform.
2. Inspect the front lifting lugs (refer to Figure 10.5) and
the rear lifting lugs (refer to Figure 10.6) to make
sure they are free of cracks and are in good condi-
tion. There are two lugs on the rear of the chassis
and two on the front. Have any damage repaired by a
qualified service technician before attempting to hoist
the machine.

3. Remove all personnel, tools, materials, or other loose
objects from the platform.
4. Connect the chains or straps to the lifting lugs using
bolted shackles. Hooks that fit properly in the lugs
and that have latching mechanisms to prevent them
from falling out under a slack line condition may also
be used.
Do not run the sling cable through the lifting lugs.
Cable damage and/or failure can result from the cable
contacting the sharp corners of the lift lug. There is
no effective way of putting a corner protector in the
hole of the lug.
