6.1.1.
The Bar Graph
This is the rectangular bar that is in the top centre of the LCD. This gives an “analogue” indication
of the percentage the current load is of the Safe Working Load. The bar will start to grow when the
load is 50% of the SWL and reach the amber section at 85%. The start of the red section
corresponds to 100% rated capacity.
6.1.2.
SWL
The displayed S.W.L. is extracted from memorised look-up load-charts and will depend on the
current crane configuration, duty, winch selected, the maximum line-pull and the falls selected.
6.1.3.
Length
This is the current TOTAL boom length as selected from the Crane Duty Listing provided for each
System. TOTAL boom length includes any attachment/s as specified by the current crane
configuration duty.
eg. For a SINGLE WINCH CRANE with #1 winch selected for a MAIN BOOM configuration,
the boom length will be the MAIN boom, however, for a fly-jib selected configuration the
boom length will be the MAIN + FLY-JIB length.
eg. For a TWIN WINCH CRANE,
#1 winch selected will display MAIN BOOM length and,
#2 (or #3) winch selected will show TOTAL BOOM length inclusive of the Upper Boom
Point (rooster sheave) OR inclusive of the FLY-JIB.
6.1.4.
Angle
This is the current boom angle. This angle will be either the MAIN BOOM, OR the LUFFING FLY
(when selected and in use)
6.1.5.
Radius
Shows the operating radius for the CURRENT CONFIGURATION and DUTY and WINCH
selection. The radius is calculated from the Boom Angle and Length sensors with compensation
applied to include, slew offset distance, head sheave radius and boom deflection.
6.1.6.
Load
This shows the current total lifted load for the selected winch. For endless/tandem reeving it will
show the total load of both winches. Please note that this load value may contain some TARE
value. The TARE lamp being on indicates this
(see TARE function later in this section).
Use the WINCH button to switch between #1, # 2 or #3 selection.
INVALID WINCH SELECTIONS WILL BE DISABLED IN SOFTWARE.
Although the RCI-1550 will always check safe operation for all winches, you should make sure that
the correct winch is selected as the winch selection affects the values shown on the displays.
When the ACTUAL LOAD exceeds the SWL for the current crane configuration the RCI-1550 will
activate audible and visual alarms.
