OPERATING PROCEDURES GRT9165 OPERATOR MANUAL
4-50 Published 7-23-2020, Control # 668-02
Load = 36.0 (a higher load than above)
Length = 150.0
A new table of available boom configurations can appear
and a new selection can be made and sent to the Semi-auto
telescoping mode.
Finally, if it is desired to keep lifts within a criterion such as
75% of the maximum values for the load chart data, then the
search can be based on a modified hook load. The modified
hook load value would be the hook load divided by the
decimal value for the desired limitation such as the following:
P
modified
= P / 0.75
For example, if hook load is 10,000 lbs, and 0.75 is the
modification desired, then the value to enter on the Boom
Configurator screen would be the following:
P
modified
= 10,000 / 0.75
P
modified
= 13,333
Thus, enter the value of 13.5 klbs for the Boom Configurator.
