Set Zero and Direction of Swing Pot.
Set the machine to the over front swing area and zero the swing pot. Swing the machine in a clockwise
direction (to the right) and set the direction indicator to ‘+’.
Check the swing angle shown increments as you swing the crane to the right, at 360 degrees the angle
indicator will roll over to zero degrees and you should be back over the front of the machine again
.
Calibrate Main Boom(s)
It is necessary to calibrate radius, moment and deflection for each telescoping mode of the main boom.
Almost all machines have two telescoping modes of operation for the boom. This would include:
Main boom – manual retracted
Main boom – manual extended
Main boom – Power pinned section retracted
Main boom – Power pinned section extended
Main boom mode A
Main boom mode B
Up to four main booms may be calibrated (normally two). The correct configuration must be selected
before carrying out each boom calibration.
Follow all steps – Radius/Moment, Boom deflection correction and Boom Head angle for each Main
Boom Telescoping Mode.
Make sure the correct Boom configuration is selected before continuing.
Note: - Head angle calibration is also required for each boom mode that is capable of erecting a fly.
