SYSTEM DESCRIPTION
The MicroGuard
®
414 Rated Capacity Indicator (RCI) System for lattice boom cranes is intended to aid
the crane operator in efficient crane operation by continuously monitoring the load and warning the
operator of an approaching overload or Two-Block condition. Monitoring crane functions is accomplished
with the use of highly accurate sensors that continuously compare the load suspended below the boom
head with a copy of the crane capacity chart stored in the computer memory. When an approaching
overload or Two-Block condition is sensed by the system, audible and visual alarms activate. This
System can also be configured to cause cessation of boom movement – winch up, boom down, and
extend out (function kick-out).
The MicroGuard
®
414 Rated Capacity Indicator (RCI) System for lattice boom cranes is used with the
MicroGuard
®
Rated Capacity Indicator (RCI) 414 Display.

♦
Working Area (if applicable)
♦
Crane

messages are displayed in the left and
upper right displays. The lower right
display provides information about the
currently selected crane configuration.
