3.1 BOOM ASSEMBLY
The boom assembly, Fig. 3.1, consists of inner,
intermediate, and outer booms. The intermediate
boom slides in the outer boom and the inner boom
slides in the intermediate boom. As the boom
extend/retract cylinder extends or retracts the
intermediate boom, a pair of extend chains and one
retract chain moves the inner boom in the same
direction.
IMPORTANT: The inner, intermediate and outer
boom replacement instructions in paragraphs 3.1.1
through 3.1.3 must be completed in sequence.
Replacement of two or more booms as a unit
requires special considerations that are not covered
in these instructions.
