GRT8120 OPERATOR MANUAL SAFETY INFORMATION
2
Slopes
- Pick and carry on level surfaces only.
- Refer to the Operation Section for more detailed
information on traveling on slopes.
- Driving across a slope is dangerous, as unexpected
changes in slope can cause tip over. Ascend or
descend slopes slowly and with caution.
- When operating on a downhill slope, reduce travel
speed and downshift to a low gear, to permit
compression braking by the engine, and aid the
application of the service brakes.
WORK PRACTICES
Personal Considerations
Always adjust the seat and lock it in position, and fasten the
seat belt securely before you start the engine.
Do not wear loose clothing or jewelry that can get caught on
controls or moving parts. Wear the protective clothing and
personal safety gear issued or called for by the job
conditions. Hard hat, safety shoes, ear protectors, reflective
clothing, safety goggles, and heavy gloves may be required.
Crane Access
You must take every precaution to make sure that you do not
slip and/or fall off the crane. Falling from any elevation could
result in serious injury or death.
Never exit or enter the crane cab or deck by any other means
than the access system(s) provided (i.e., steps and grab
handles). Use the recommended handholds and steps to
maintain a three-point contact when getting on or off
the crane.
If necessary, use a ladder or aerial work platform to access
the boom nose.
Do not make modifications or additions to the crane’s access
system that have not been evaluated and approved by
Grove Crane.
Do not step on surfaces on the crane that are not approved
or suitable for walking and working. All walking and working
surfaces on the crane should be clean, dry, slip-resistant,
and have adequate supporting capacity.
Do not walk on a surface if slip-resistant material is missing
or excessively worn.
Do not use the top of the boom as a walkway.
Do not step on the outrigger beams or outrigger pads (floats)
to enter or exit the crane.
Use the hoist access platform (if equipped) when working in
the hoist area.
Wear shoes with a highly slip-resistant sole material. Clean
any mud or debris from shoes before entering the crane cab/
operator’s station or climbing onto the crane superstructure.
Excessive dirt and debris on the handholds, access steps, or
walking/working surfaces could cause a slipping accident. A
shoe that is not clean might slip off a control pedal during
operation.
Do not allow ground personnel to store their personal
belongings (clothing, lunch boxes, water coolers, and the
like) on the crane. This practice will prevent ground
personnel from being crushed or electrocuted when they
attempt to access personal belongings stored on the crane.
Job Preparation
Before crane use
• Barricade the entire area where the crane is working and
keep all unnecessary personnel out of the work area.
• Make sure that the crane is properly equipped, including
access steps, covers, doors, guards, and controls.
• Conduct a visual inspection for cracked welds, damaged
components, loose pins/bolts, and wire connections.
Any item or component that is found to be loose or
damaged (broken, chipped, cracked, worn-through, etc.)
must be repaired or replaced. Inspect for evidence of
improper maintenance (consult your
Service Manual ).
• Check for proper functioning of all controls and operator
aids (for example, RCL).
• Check all braking (for example, wheel, hoist, and swing
brakes) and holding devices before operation.
You must make sure that the outriggers and jack cylinders
are properly extended and set before performing any lifting
operations. On models equipped with outriggers that can be
pinned at the mid-extend position, the outriggers must also
be pinned when operating from the mid-extend position.
Clear all personnel from the outrigger area before extending
or retracting the outriggers. Carefully follow the procedures
in this
Operator Manual when extending or retracting the
outriggers. Death or serious injury could result from improper
crane set up on outriggers.
Be familiar with surface conditions and the presence of
overhead obstructions and power lines.
WARNING
Fall Hazard!
Working at elevated heights without using proper fall
protection can result in severe injury or death.
Always use proper fall protection as required by local,
state or federal regulations.
