Step #15: “No Load calibration”
Before proceeding with this section, ensure that all previous sections have been
completed, in particular that all dimensions have been entered correctly and all sensors
are correctly calibrated.
The No load calibration procedure must be carried out for each of the Boom Mode
configurations to record the empty boom weight. For example a separate no‐load
calibration needs to be done for main boom with the manual section in, and the manual
section out.
For machines with more than one length sensor where multiple no load calibrations are
done the system will continue to monitor the temporarily non‐telescoping section(s) to
ensure it is not moved. If a change is detected then the calibration will be suspended
until the situation is corrected.
For all other configurations using the same main Boom Mode but with an attachment
fitted (i.e. main boom + jib stowed, main boom + jib erected, lifting over jib, etc…) no
other no load calibration is necessary. The system will calculate the load on the hook in
use making allowance for the fitted attachment using the weight and center of gravity
of the attachment already stored in memory.
For any given basic Boom Mode calibration it is highly recommended that all
unnecessary stowed attachments are removed from the boom to ensure the best result.
Only the main block should be rigged during a no load calibration and no jibs should be
fitted or stowed, including rooster sheave assemblies. Refer to the duty list to
determine the appropriate configuration for no load calibration and to the system
configuration section of the Instruction manual.
The crane needs to be rigged for each of these main boom conditions and the
appropriate duty needs to be selected before starting this procedure. Since this also
applies to boom deflection calibration, it is recommended to do both no‐load and boom
deflection calibrations while the machine is rigged on one particular condition to save
time.
Notes:
1. During this procedure boom angle, boom length and pressures are displayed at
various times for reference purposes on the display window.
2. The derrick motion immediately before recording a calibration point should
always be up/in. If it was necessary to derrick down/out, then derrick up/in
slightly before recording the calibration point. When telescoping in or out it is
not necessary to derrick up/in, unless the crane has had to be derricked down/out
during telescoping for some other reason.
3. Ensure that the crane chassis is level for all no load, boom deflection, and load
correction calibrations.
