RT540E OPERATOR MANUAL
Traveling — General
WARNING
Inadvertent Operation Hazard!
Before traveling, ensure that the crane functions are fully
disabled. The crane function enable switch is a spring
return switch and cannot be put in a specific OFF
position.This will prevent inadvertent operation of craning
functions due to bumping of the controllers while
traveling.
RT machines are subject to the same road regulations as
any truck, regarding gross weight, width, and length
limitations.
Although RT machines are specifically designed for rough
terrain, the operator should be extremely cautious and aware
of the terrain in which he is operating.
WARNING
Tipping Hazard!
Avoid holes, rocks, extremely soft surfaces, and any other
obstacles which might subject the crane to undue
stresses or possible overturn.
Do not drive the crane with the boom off center because
automatic oscillation lockout will occur, making the crane
subject to tipping on uneven surfaces. Center the boom
over the front, disable swing functions and engage the
Turntable Lock Pin (if equipped).
Fully retract the boom and ensure the swingaway jib is
properly stowed and secured.
CAUTION
Machine Damage Hazard!
Do not travel with an empty hook in a position where it can
swing freely (except where noted). Either remove the
hook block and/or headache ball from the hoist cable(s)
and stow securely or make sure the hook block or
headache ball is properly secured to the tie down
provided for that purpose.
Do not drive the crane with the lift cylinder bottomed. At a
minimum, position the boom slightly above horizontal.
Fully retract the outrigger jacks and properly store the
floats.
Disengage the pumps (if applicable) for extended
traveling.

OPERATING CONTROLS AND PROCEDURES
Use four-wheel drive only when greater traction is necessary.
(Refer to Four-Wheel Drive Operation, page 3-17 for
operating instructions.)
On open ground, tow or pull only on the tow/tie-down lugs
or with the optional pintle hook.
Do not tow or pull in 1st gear with the Drive Axle Selector
Switch in two-wheel drive position. Severe damage to the
drive train will result. Always engage four-wheel drive.
Should the crane become mired down, use a tow truck or
tractor to free the vehicle. Severe damage to the
transmission or axles may occur if the operator attempts
to free the crane unassisted.
There are two tow/tie-down lugs installed on each end of the
crane. Use both lugs to tow or pull the crane.
Ensure the outrigger beams and jacks are fully retracted with
the floats properly stowed.
Traveling on Slopes
Crane operators need to exercise caution whenever
operating the crane on uneven surfaces. Travel on slopes is
permitted as long as the following conditions are met.
• Do not exceed a 15% (8.5°) slope side-to-side or fore-
and-aft.
• Travel must be on an improved surface or on hard-
packed dry earth having a minimum 0.5 coefficient of
adhesion.
• Limit travel to a forward direction only.
• Do not exceed a speed of 1.6 km/h (1 mph).
• Fully retract all boom sections.
• Stow or remove the boom extension from the crane.
• Lower the boom to horizontal and position over the front
of the crane.
• Engage the swing brake and turntable lock pin.
• Either the hook block may be reeved over the main
boom nose or the headache ball may be reeved over the
main boom nose or auxiliary boom nose; the other must
be removed. If the hook block or headache ball remains
reeved on the boom, it must be secured at the tie down
on the carrier to prevent swinging.
• Inflate tires to the recommended pressure for pick and
carry operations.
• Ensure the hydraulic tank is filled to the specified level.
Ensure the fuel tank is over half full.
