attempting to operate aerial lift on which you have not been
trained.
You must be mentally and physically fit to operate an aerial
lift. Never attempt to operate an aerial lift while under the
influence of medication, narcotics, or alcohol. Any type of
drug could impair physical, visual and mental reactions, and
capabilities.
As operator of this aerial lift, you are granted the authority to
stop and refuse to lift loads until safety is assured.
OPERATIONAL AIDS
Operational aids are accessories that provide information to
facilitate operation of an aerial lift or that take control of
particular functions without action of the operator when a
limiting condition is sensed. Examples of such devices
include, but are not limited to, the following: rated capacity
indicator, rated capacity limiter, boom angle or radius
indicator, boom length indicator, aerial lift level indicator and
wind speed indicator.
National Crane remains committed to providing reliable
products that enable users and operators to safely lift
personnel. National Crane has been an industry leader in the
incorporation of operational aids into the design of its aerial
lifts. Federal law requires that aerial lifts be properly
maintained and kept in good working condition. The manuals
that National Crane provides that are specific for each aerial
lift and the manufacturer’s manuals for the operational aids
shall be followed. If an operational aid should fail to work
properly, the aerial lift user or owner must assure that repair
or recalibration is accomplished as soon as is reasonably
possible. If immediate repair or recalibration of an
operational aid is not possible and there are exceptional
circumstances which justify continued short-term use of the
aerial lift when operational aids are inoperative or
malfunctioning, the following requirements shall apply for
continued use or shutdown of the aerial lift:
• Steps shall be taken to schedule repairs and
recalibration immediately. The operational aids shall be
put back into service as soon as replacement parts, if
required, are available and the repairs and recalibration
can be carried out. Every reasonable effort must be
made to expedite repairs and recalibration.
• When a Load Indicator, Rated Capacity Indicator, or
Rated Capacity Limiter is inoperative or malfunctioning,
the aerial lift shall be shut down until repairs can be
made. When a Boom Angle or Radius Indicator is
inoperative or malfunctioning, the radius or boom angle
shall be determined by measurement.
• When a Level Indicator is inoperative or malfunctioning,
other means shall be used to level the aerial lift.
Rated Capacity Limiter (RCL) System
Your aerial lift is equipped with an RCL system which is
intended to aid the operator. An RCL is a device that
automatically monitors radius, work platform capacity and
prevents movements of the aerial lift which would result in an
overload condition.
Test daily for proper operation. Never interfere with the
proper functioning of operational aids or warning devices.
Under no condition should it be relied upon to replace the
use of Load Chart/Reach Diagrams and operating
instructions. Sole reliance upon these electronic aids in
place of good operating practices can cause an accident.
Know the load in the work platform is within the capacity of
the aerial lift before operation.NEVER exceed the rated
capacity of the aerial lift. Always check the Reach Diagram to
ensure the desired platform reach or platform height is within
the capability of the aerial lift.
For detailed information concerning the operation and
maintenance of the RCL system installed on the aerial lift,
see the RCL manufacturer’s manual supplied with the aerial
lift. Manufacturers of rated capacity limiters may refer to
them in their manuals as a load moment indicator (LMI), a
hydraulic capacity alert system (HCAS), a safe load indicator
(SLI); National Crane refers to these systems as a rated
capacity limiter (RCL) throughout its Operator and Service
Manuals.)Never interfere with the proper functioning of
operational aids or warning devices.
Working Area Limiter (If Equipped)
This aerial lift may be equipped with a working area limiter as
part of the RCL system, designated as either Work Area
Definition System (WADS) or Working Range Limiter (WRL).
You must read and understand the operator manual before
operating the working area limiter system. Become familiar
with all proper operating procedures and with the
identification of symbol usage.
The working area limiter is intended to be used as an aid to
the operator. It is not a substitute for safe aerial lift operating
practices, experience and good operator judgements.
AERIAL LIFT STABILITY/STRUCTURAL
STRENGTH
To avoid death or serious injury, ensure that the aerial lift is
on a firm surface.Ensure all pins and floats are properly
installed and outrigger beams are properly extended before
operating the aerial lift. Use adequate cribbing under
outrigger floats to distribute weight over a greater area.
Check frequently for settling.
Read and follow the safety decals and instructions for aerial
lifts with center front stabilizers.
