#LMI operating code. Refer to LMI manual for operating instructions.
*This capacity is based upon maximum boom angle.
NOTES:
1. All capacities above the bold line are based on
structural strength of boom extension and do
not exceed 85% of tipping loads, in accordance
with SAE J-765.
2. The 33 ft luffing folding boom extension may be
used for single or double line lifting service. The
56 ft luffing folding boom extension may be
used for single line lifting service only.
WARNING: Lifting with the 33 ft extension
base, with the 23 ft extension fly either erected
or folded along side of extension base, is
strictly prohibited.
3. 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.
4. Boom angle is the angle above or below
horizontal of the longitudinal axis of the boom
base section after lifting rated load.
5. Capacities listed are with outriggers properly
extended and vertical jacks set only.
6. For main boom lengths less than 141.7 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.
7. When lifting over the main boom nose with
33 ft or 56 ft extension erected, the outriggers
must be fully extended or 50% extended (17.3 ft
spread).
