Travel 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 1.5 km/h (1 mph).
• Fully retract all boom sections.
• Stow or remove the jib 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 hookblock may be reeved over the main boom
nose or the overhaul ball may be reeved over the main
boom nose or auxiliary boom nose, the other must be
removed. If the hookblock 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
• Engine and transmission fluids must be filled to the
specified levels.
• Axle differentials and planetary hub fluids must be filled
to the specified levels.
• Do not support any loads by the boom (i.e., no pick and
carry loads) while traversing a slope.
• Remove all cribbing or other non-standard accessories
from the crane.
• Avoid holes, rocks, extremely soft surfaces, and any
other obstacles that might subject the crane to undue
stresses and possible overturn.
• Conduct all travel with the assistance of a ground person
to warn the operator of any changing conditions in the
terrain being traversed.
• "Slope limitations:
- Side to side slope shall not exceed 15% (8.5
degrees) & travel speed shall not exceed 1 MPH on
a side slope.
- Fore-and-aft slope shall be less than or equal to
15% (8.5 degrees) for normal crane travel.
- For fore-and-aft slope greater than 15% (8.5
degrees) and less than 25% (14 degrees) the
transmission shall be in 4-wheel-drive and travel
speed shall not exceed 1 MPH. If the crane will be
parked the transmission shall be in 4-wheel drive
and the wheels shall be chocked.
- For fore-and-aft slope equal to or greater than 25%
(14 degrees) an assist vehicle is required, the
transmission shall be in 4-wheel drive, and the
crane shall not be parked.
- Maximum fore-and-aft slope is 30% (16 degrees).
- For machine/application specific slope limitations
(e.g. heavy counterweight) refer to the operators'
manual.
Should the operator of an affected model need to traverse
slopes outside of the criteria set forth in this publication, or
traverse slopes with other crane models not addressed
herein, please contact Grove U.S. L.L.C. for further
guidance.
The owner/lessee must take appropriate measures to
ensure that all persons operating or working with the affected
models are in compliance with Grove U.S. L.L.C.
recommendations. The operator of the crane assumes
responsibility for determining the suitability of traveling on a
slope. Traveling on a slope should only be attempted under
the controlled conditions specified in these guidelines, and
must be conducted with the utmost diligence and care to
ensure the safety of all personnel performing the operation
and/or working around the crane.
Should the operator need to traverse slopes outside the
criteria defined in the above guidelines contact Grove U.S.
L.L.C. for further guidance.
Traveling with Elevated Boom
NOTE: Ensure that all personnel involved in the operation
and those working around the crane are aware of
any hazards that may be encountered and are
trained about how to avoid the hazards.
WARNING
Overhead Objects Hazard!
Contacting overhead objects while driving the crane or
driving the crane over rough terrain with the boom
elevated may result in death, severe injury, and/or
equipment damage. Traveling with the boom elevated
should only be attempted under the controlled conditions
specified in this section.
