Aerial Loading
The Class1 Aerial Loading Display is designed to warn aerial operators of
dangerous loading conditions when an aerial device is operated at low angles
of elevation. Live loads (factors that increase this load such as ice, occu-
pants on the ladder, water load, extra equipment, etc.) are instantly taken into
account by the system and displayed to the operator.
The display presents load information in an easy to interpret LED bargraph
display as a percentage of maximum calibrated load and includes visual and
aural warnings.
When the aerial load approaches the maximum load (approx. 80%), 18-20
bars will be illuminated on the display. When the load is increased to 90%-
100%, the display will begin to flash, when the maximum load is exceeded by
50-100 pounds, an audible alarm output is activated in addition to the visual
warning to notify the operator of a potentially hazardous condition.
NOTE:
THE DISPLAY PROVIDES A WARNING ONLY AND CANNOT
