Three methods may be used to raise and lower boom and luffing jib combinations, depending on length:
A. Layout In-Line Method
Boom and luffing jib are assembled in layout, end-to-end, position. Slowly raise boom until luffing jib stop strut
is just clear of ground. Attach luffing jib stop pendants and unpin luffing jib stop inner strut from retracted
position. Slowly raise boom until luffing jib stop strut is fully extended and pins engaged (approximately 168
degree boom-to-luffing jib angle). Tighten luffing jib suspension with luffing jib hoist. Boom and luffing jib can
then be raised simultaneously using only the boom hoist. Reverse this procedure when lowering boom and
luffing jib.
Boom and luffing jib combinations in following tables may be raised and lowered using layout in-line method.
