SYSTEM DESCRIPTION
SYSTEM DESCRIPTION
SYSTEM DESCRIPTIONSYSTEM 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).

operation of the system. These
messages are displayed in the left and

MAXMUM RATED CAPACITY (1)
is the maximum permitted capacity of the
crane. This value, which appears digitally in
the left display, is derived from a copy of the
crane's capacity chart stored in the memory
of the computer.

MAXIMUM RATED CAPACITY is the
reference capacity for any lifting operation
and is dependent on the crane configuration
currently selected. The currently selected
configuration must be the same as the actual
configuration. The current selection may be
viewed in the lower right display. The crane
configuration determines the section of the
capacity chart used as the capacity
reference. If the MAXIMUM RATED
CAPACITY is limited by parts-of-line, the
DISPLAYED MAXIMUM RATED CAPACITY
The BAR GRAPH (2) is an analog BAR GRAPH that shows the amount of crane capacity being used
and the rate at which an overload is being approached. This BAR GRAPH in conjunction with the 100%
capacity marker visually indicates when an overload point is reached.
PERCENT OF RATED CAPACITY (3) is shown as a digital read out in which Actual Load appears as
a percentage of Maximum Rated Capacity. For percentages less than 100%, the read out will be at the
right side of the bar graph. For percentages over 87%, the display will move to the center of the bar graph
to make space for the leading edge of the bar graph.
The INFORMATION AREA (4) provides the operator with a visual indicator of the various alarms that
may occur during normal operation of the system. For example, PRE-ALARM, OVERLOAD, ATB ALARM,
or ROPE LIMIT.
ACTUAL LOAD (5) is a digital display that shows the total load suspended below the boom or jib head.
It includes the load, slings, pins, or tackle used to secure the load, and the hook block. Using the
STOWED DEDUCT button, the operator can "tare out” the slings and hook (see page 9).

RADIUS/HEIGHT (1) gives a continuous indication of the radius of the load, which is the horizontal
distance from the centerline of rotation to the centerline of the hook. When the Radius/Height push button
is pressed, the display will give a momentary read
out of the height of the boom head above ground
level, i.e. the vertical distance from the ground to
the boom/jib head. Information about height is
only displayed while the Radius/Height push
button is pressed and held.
PARTS-OF-LINE (2) shows the parts-of-line
currently selected. If the parts-of-line selected has
a lower safe working strength than the actual
capacity, the MAXIMUM RATED CAPACITY
display will show the reduced capacity and the
message, "ROPE LIMIT" will be displayed in the
information area.

from the boom foot pin to the shaft of the head machinery. Information about length is only displayed while
the Angle/Length push button is pressed and held.
THE BARGE MOUNT SELECTION (6) shown in the lower left of the upper right display is
determined by the current duty selection.
THE LIFTING POINT-150 FT FROM MAIN BOOM CONFIGURATION (7) is continuously
displayed on the upper line of the lower display.
The WORKING AREA (5) is in the lower right section of the upper right display. Descriptions conform
to the current configuration selected and to the swing position of the crane upper. On this crane, it will only
display 360° (AS SHOWN).
