NOTES:
. All capacities above the bold line are
based on structural strength of boom
extension and do not exceed % of
tipping loads, in accordance with SAE
J .
. The ft luffing folding boom
extension may be used for single line
lifting service only.
. WARNING: Operation of this
machine with heavier loads than the
capacities listed is strictly prohibited.
Machine tipping with boom
extension occurs rapidly and without
advance warning.
. WARNING: Lifting with the
ft extension base, with the ft
extension fly either erected or folded
along side of extension base, or with
either one or two ft insert sections
installed, is strictly prohibited.
. For main boom lengths less than
ft with the boom extension erected,
the rated loads are determined by
boom angle. Use only the column
which corresponds to the boom
extension length and offset for which
the machine is set up. For boom
angles not shown, use rating of the
next lower boom angle.
. When lifting over the main boom
nose with the ft extension erected
and inserts, the outriggers must be
fully extended and vertical jacks set.
