Step #15: Main boom “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. A
separate calibration is available for each crane configuration that also has an individual
no load calibration, but is not used for configurations with boom attachments (refer to
Section 3.10).
A no load calibration should be completed before continuing with this procedure.
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
