[1] BOOM LENGTH
“Boom (1)”, “Booms (1) + (2)”, “Booms (1) + (2) + (3)”, “Booms (1) + (2) + (3) + (4)” and “Booms
(1) + (2) + (3) + (4) + (5)” shown on the top horizontal column of the Rated Total Load Chart
represent the conditions shown in the following figures.
1. Boom (1): All the booms retracted.
2. Booms (1) + (2): All of booms (3), (4) and (5) are retracted, with boom (2) fully extended.
If boom (2) is extended to some extent, work should be performed in accordance with the
performance of this column.
3. Booms (1) + (2) + (3): Both of booms (4) and (5) are retracted, with booms (2) and (3) fully
extended.
If boom (3) is extended to some extent even only slightly, work should be performed in
