2)
Accurately measure the actual radius of the hook block from the centre line of slew
of the machine.
3)
Use

to adjust the Corr.:

value until the displayed radius equals the
measured radius, note that the indicated radius can only be increased, not
decreased. Press
“
”
to accept the change, the system will confirm the calibration
is saved.
4)
The display will show the current boom length and an another target boom length
for calibration. With the hook block suspended, telescope the boom in to the target
length specified on the display, this is normally the half extension available, be sure
to check that the hook block does not foul the boom tip and that the boom is at a
high enough angle to safely permit the half extension.

3.6 Step #14: “Loaded boom deflection”
This procedure is used to add an allowance into the calculation of the hook radius to
compensate for main boom and/or chassis deflection due to a suspended load.
This procedure should only be used with machine configurations on outriggers or on
crawlers.
A known test weight is required to carry out this calibration, the weight should be
between 50% and 90% of the SWL for the configuration being calibrated and should be
based on the SWL with a fully extended boom at approximately 60° boom angle. The
calculated test load should normally include the weight of the hook block and any slings,
shackles etc. that are used.
1)
Use
“

or
“
”
to highlight “Loaded boom deflection” and press
“
”
to enter.
The display will show the current boom length and a target boom length for calibration.
