Note 1: For most applications, weight of luffing jib and a certain
amount of weight below lower luffing jib point have
been included in boom capacity determination and do
not have to be added to total load.
See capacity chart
for detailed information
.
Note 2: Depending on jib length, some lower boom point
sheaves may have to be removed.
See capacity chart
for detailed information
