Traveling — General
GRT machines are subject to the same road regulations as
any truck, regarding gross weight, width, and length
limitations.
Although GRT machines are specifically designed for rough
terrain, the operator should be extremely cautious and aware
of terrain operating conditions.
• Use four-wheel drive only when greater traction is
necessary. (Refer to Four-Wheel Drive Operation,
page 3-68 for operating instructions.)
• Ensure outrigger beams and jacks are fully retracted
with pads properly stowed.
• Conduct all travel with assistance of a ground person to
warn operator of any change in terrain conditions.
Owner/lessee must take appropriate measures to ensure all
persons operating or working with affected models are in
compliance with Grove recommendations. Operator of the
crane assumes responsibility for determining suitability of
traveling conditions. Traveling under controlled conditions
specified in these guidelines, must be conducted with the
utmost diligence and care to ensure safety of all personnel
performing the operation and/or working around the crane.
Traveling — Towing/Pulling
WARNING
Inadvertent Operation Hazard!
Before traveling, ensure 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 controllers while traveling.
WARNING
Tipping Hazard!
Avoid holes, rocks, extremely soft surfaces, and any other
obstacles which might subject crane to undue stresses or
possible overturn.
Do not drive crane with boom off center because
automatic oscillation lockout will occur, making crane
subject to tipping on uneven surfaces. Center boom over
front, disable swing functions, and engage Turntable Lock
Pin.
Fully retract boom. Ensure 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). Remove hook block
and/or overhaul ball from hoist cable(s) and stow securely
or make sure hook block or overhaul ball is properly
secured to tie down provided for that purpose.
Do not drive crane with lift cylinder bottomed. At a
minimum, position boom slightly above horizontal.
Fully retract outrigger jacks and properly store pads.
Disengage pumps (if applicable) for extended traveling.
CAUTION
Machine Damage Hazard!
Grove Crane recommends towing or pulling another
vehicle with the optional pintle hook (if equipped) or by
attaching at a point no higher than pintle hook height, or
severe damage may occur to the drivetrain.
Do not tow or pull by attaching to tie-down lugs unless
attaching point is no higher than pintle hook height.
Use four-wheel drive when greater traction is necessary
to avoid severe damage to the drivetrain.
Should crane become mired, use a tow truck or tractor to
free the vehicle. Severe damage to drivetrain may occur if
operator attempts to free crane unassisted.

Should the crane become mired down, use a tow truck or
tractor to free the vehicle. Severe damage to the
drivetrain may occur if the operator attempts to free the
crane unassisted.
