Transporting
The aerial platform may be moved on a transport vehicle.
Depending on the particular situation, the aerial platform
may be driven, winched, or hoisted onto a vehicle such
as a truck or trailer. Driving is the preferred method.
A
Danger
The aerial platform can tip over if it becomes un-
stable. Death or serious injury can result from a tip-
over accident. Do not drive on ramps that exceed
25 percent grade, or where conditions of the ramp
could cause driving to be hazardous.
Drive the aerial platform onto the transport vehicle if the
ramp incline is within the 25 percent grade capability of
the aerial platform.
A 25 percent grade is a 30
″
(0.76 m) vertical rise in 10
′
(3.05 m) horizontal length.
Use a winch to load and unload the aerial platform on
ramps that exceed 25 percent grade. A winch may also
be used when conditions of the ramp could cause driving
to be hazardous.
The equipment used to load, unload, and transport the
aerial platform must have adequate capacity. Refer to
Chapter 2 to determine the approximate weight of the
aerial platform.
The user assumes all responsibility for choosing the
proper method of transportation, and the proper selection
and use of transportation and tie-down devices, making
sure the equipment used is capable of supporting the
weight of the aerial platform and that all manufacturer’s
instructions and warnings, regulations and safety rules
of their employer, the DOT and/or any other state or fed-
eral law are followed.
Driving
Use the following procedure to drive the aerial platform
onto the transport vehicle.
1. Locate the transport vehicle so it is in a straight line
with the loading ramp.
2. Chock the vehicle wheels so it cannot roll away from
the ramp while the machine is loaded.
3. Remove any unnecessary tools, materials, or other
loose objects from the platform.
4. Drive the machine to the foot of the loading ramp with
the front wheels nearest the ramp. Make sure the
machine is centered with the ramps and that the steer-
ing wheels are straight.
5. Rotate the platform so it is perpendicular to the boom.
6. Retract the tip boom and raise the jib so it is horizon-
tal.
7. Rotate the turntable slightly to the side so you can
see the front wheels.
8. Verify that the machine wheels, loading ramps, and
transport vehicle are aligned.
A
Danger
The aerial platform can tip over if it becomes un-
stable. Death or serious injury can result from a tip-
over accident. Set the drive range to low before
driving up or down a grade.
9. Place the drive range switch in the low position.
10. Drive the aerial platform onto the transport vehicle in
a straight line through the grade transitions with mini-
mal turning.
11. Rotate the turntable to align the main boom between
the rear wheels.
12. When driving down the ramp, always back the ma-
chine with the platform on the downhill side only.
Winching
Use the following procedure to winch the aerial platform
onto the transport vehicle.
1. Locate the transport vehicle so the aerial platform
will not roll forward after it is loaded.
2. Remove any unnecessary tools, materials, or other
loose objects from the platform.
3. Drive the machine to the foot of the loading ramp with
the front wheels nearest the ramp. Make sure the
machine is centered with the ramps and that the steer-
ing wheels are straight.
4. Properly stow the aerial platform.
5. Attach the winch to the tie-down lugs (refer to Figure
9.3) on the front of the chassis.
