Chapter 9 – Stowing and Transporting

Driving

Danger
The aerial platform can tip over if it becomes un-
stable. Death or serious injury will result from a tip-
over accident. Do not drive on ramps that exceed
the machine gradeability specifi cation, or where
conditions of the ramp could cause driving to be
hazardous.
Use a winch to load and unload the aerial platform on
ramps that exceed the machine gradeability specifi cation.
A winch may also be used when poor traction, uneven
surfaces, or stepped ramp transitions make driving
hazardous.
Drive the aerial platform onto the transport vehicle if a
winch is not available and the ramp incline is within the
35 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.
Caution
The extension deck is free to move when the exten-
sion handle locks are disengaged. Personal injury
may result from accidentally extending or retracting
the deck. Make certain both extension handle locks
are fully engaged when the deck is extended in the
working position and when it is stowed. Do not at-
tempt to extend or retract the platform unless the
aerial platform is on a level surface.
4. Fully retract the platform extension deck and ensure
that it is secured in position, with the latch handles
fully lowered and the locks fully engaged. Fully lower
the platform.
5. Drive the aerial platform to the foot of the loading
ramp with the rear 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 ve-
hicle in a straight line through the grade transitions
with minimal turning.

Danger
Pinch points may exist between moving compo-
nents. Death or serious injury will result from be-
coming trapped between components, buildings,
structures, or other obstacles. Make sure there is
suffi cient clearance around the machine before
moving the chassis. Allow suffi cient room and time
to stop movement to avoid contact with structures
or other hazards.
Note
To make an emergency stop push the emergency stop
button inward to apply the parking brakes.

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 anywhere else.
Warning
The potential for an accident increases when the
aerial platform is lifted using improper equipment
and/or lifting techniques. Death or serious injury
could result from such accidents. Use proper equip-
ment and lifting techniques when lifting the aerial
platform.
Know the weight of the aerial platform and the capacity
of the lifting devices before hoisting.
Ÿ
Lifting devices include the hoist or crane, chains,
straps, cables, hooks, sheaves, shackles, slings,
and other hardware used to support the machine.
Ÿ The empty vehicle weight is stamped on the serial
number placard and is listed in Chapter 2.
The user assumes all responsibility for:
Ÿ Making sure the equipment used is capable of sup-
porting the weight of the aerial platform.
Ÿ Making sure all manufacturer's instructions and
warnings, regulations and safety rules of their em-
ployer 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 and the rear lifting lugs
to make sure they are free of cracks and are in good
condition. There are two lugs on the rear of the chas-
sis and two on the front (see fi gure 9.3). Have any
damage repaired by a qualifi ed service technician
before attempting to hoist the machine.
