COMMAND 07 RADIUS/MOMENT MAIN BOOM
COMMAND 07
is used to calibrate the radius and moment
of the main boom.
Before starting Command 07, ensure that the crane is appropriately configured and that the
related data has been entered into the computer (see pages 29-33).
This Command requires computer entry of the radius measured with the boom retracted at both
high and low angles, and the radius measured with the boom extended to the prescribed
lengths at both high and low angles. The radius is the distance between the centerline of
rotation and the center of the hook load.
Calibration is carried out at each length. Both high and low angle radius measurements for each
length are required for the calibration to operate. This data is called “store data.”
If this data is not stored, a warning message “no data” will appear requiring re-entry of this
information.
Radii are entered in tenths of feet. Recommend using a surveyor’s tape that is marked in tenths.
A high angle is between 60 ° and 65 ° and will have a shorter radius. A low angle is below
20 ° and will have a longer radius.
Entering data outside of these limits will result in the
warning message
, “poor angle.”
If entered in error,
Press D
to abort the entry. Continue the
procedure using correct keyboard entries.
When this message occurs due to entry of data outside of the preferred angles, press A or B to
select the desired function; then enter the radius.
The routine on pages 38-41 is used for the main boom. The routine on pages 42-45 is used for
the main boom + manual. Select the appropriate routine and continue.
If and when calibrating the main boom + manual, first select main boom + manual as well as
setting up the crane in that physical configuration.
Interpretation of the display Command 07 output is as follows
:
(
D
) = LOW ANGLE DATA ACQUIRED.
(
U
) = HIGH ANGLE DATA ACQUIRED.
(
DU
) = HIGH AND LOW ANGLE DATA ACQUIRED.
