GRT8120 OPERATOR MANUAL OPERATING PROCEDURES
4
Traveling is permitted with the boom over the front, with or
without counterweight installed, and with boom over the rear
with counterweight installed. Traveling is not permitted with
boom over the rear with no counterweight installed.
• Use four-wheel drive only when greater traction is
necessary or as instructed in the following sections.
(Refer to
Four-Wheel Drive Operation , page 4-18 for
operating instructions.)
• Make sure 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.
Traveling — Towing/Pulling
To avoid severe damage to the drivetrain while using the
crane to tow or pull another vehicle, follow these
recommendations:
• Make sure boom is in a horizontal position and not
elevated above 0°.
• Make sure outrigger beams and jacks are fully retracted
with the pads properly stowed.
• Tow or pull on open ground when possible.
• Connect to the optional pintle hook (if equipped) or
attach cables/straps to the crane at a point no higher
than the pintle hook height.
• Select four-wheel drive (low range) (Refer to
Four-Wheel Drive Operation , page 4-18 for operating
instructions.)
• 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.
• Conduct all travel with the assistance of a ground person
to warn the operator of any changing conditions in the
terrain being traversed.
Traveling — Being Towed/Pulled
Grove recommends connecting to a pintle hook (if equipped)
or evenly attaching to the tie-down lugs when being towed by
another vehicle.
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 lock out will occur, making crane
subject to tipping on uneven surfaces. Center boom over
front or rear, disable swing functions, and engage
Turntable Swing Lock Pin.
Fully retract boom. Make sure swingaway boom
extension 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 rope 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 fully retracted. At a
minimum, position boom to horizontal.
Fully retract outrigger beams and jacks and properly stow
pads.
Disengage pumps (if applicable) for extended traveling.
CAUTION
Machine Damage Hazard!
Grove recommends towing or pulling another vehicle with
the optional pintle hook (if equipped) or by attaching at a
point no higher than the pintle hook height, or severe
damage may occur to the drivetrain.
Do not tow or pull by attaching to the tie-down lugs unless
the attaching point is no higher than the pintle hook
height.
Always use four-wheel drive (low range) to avoid severe
damage to the drivetrain.
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.
