Load moment
and anti-two block system
Standard “Graphic Display” load moment and anti-two
block system with audio-visual warning and control
lever lockout. These systems provide electronic display

moment, maximum permissible load, load indication
and warning of impending two-block condition. The
standard Work Area Definition System allows the
operator to pre-select and define safe working areas.
If the crane approaches the pre-set limits, audio-visual
warnings aid the operator in avoiding job-site
obstructions.
