NBT60XL OPERATOR MANUAL
SAFETY PRECAUTIONS
2
Follow the instructions in this manual when preparing the
equipment for travel.
If using a boom dolly/trailer, thoroughly read and understand
all the steps and safety precautions in this manual for setup
and travel.
When driving the equipment, make sure that the cab is level,
if equipped with a tilting cab.
Secure the hook block and other items before moving the
equipment.
Watch clearances when traveling. Do not take a chance of
running into overhead or side obstructions.
When moving in tight quarters, post a signal person to help
guard against collisions or bumping structures.
Before traveling with equipment, check suitability of
proposed route with regard to equipment height, width, and
length.
Never back up without the aid of a signal person to verify the
area behind the equipment is clear of obstructions and/or
personnel.
On equipment that features air-operated brakes, do not
attempt to move the equipment until brake system air
pressure is at operating level.
Check load limit of bridges. Before traveling across bridges,
make sure that they will carry a load greater than the
equipment’s weight.
If it is necessary to take the equipment on a road or highway,
check state and local restrictions and regulations.
Keep lights on, use traffic warning flags and signs, and use
front and rear flag vehicles when necessary. Check state and
local restrictions and regulations.
Always drive the equipment carefully, obeying speed limits
and highway regulations.
Stay alert at the wheel.
If equipped, make sure that the hoist access platform hand
rail and step are in the travel configuration.
Slopes:
-
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.
Equipment Access
You must take every precaution to make sure that you do not
slip and/or fall off the equipment. Falling from any elevation
could result in serious injury or death.
Never exit or enter the equipment 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
equipment.
If necessary, use a ladder or aerial work platform to access
the boom nose.
Do not make modifications or additions to the equipment
access system that have not been evaluated and approved
by National Crane.
Do not step on surfaces on the equipment that are not
approved or suitable for walking and working. All walking and
working surfaces on the equipment 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 equipment.
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 equipment
cab/operator’s station or climbing onto the equipment
superstructure. Excessive dirt and debris on the handholds,
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.
