Two methods may be used to raise and lower boom and luffing jib combinations.
A. Layout In-Line Method
Boom and luffing jib are assembled in layout, end to end, position. Boom and luffing jib must be inline over end of blocked
crawlers prior to raising boom and luffing jib. Slowly raise boom until angle between boom to luffing jib is approximately
172 degrees. Jib stop pins should engage automatically when inner strut is fully retracted. Visually observe that these pins are
fully engaged before raising boom and jib. 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 table below may be raised and lowered using layout in-line method.
