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
is the ROPE CAPACITY and the message, ROPE LIMIT will appear in the information area (4).
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).
