and luffing jib make-up of inserts, straps, struts, strut raising procedure, jib stop positioner setup
and operation, jib stop raising and lowering procedure and miscellaneous parts, etc.
Boom and luffing jib combinations must be raised and lowered using jack-knife method.
Release swing brake (disengage swing lock) and slowly raise boom while jib point dolly is
allowed to roll on ground. Tension should be applied to luffing jib hoist to keep jib strut off
luffing jib during boom raising. Boom up until boom to luffing jib angle reaches 140 degrees.
Extend jib stop positioner cylinders (see procedure). Continue to boom up until boom to
luffing jib reaches value specified in table. Tighten luffing jib suspension with luffing jib
hoist. Boom and luffing jib are then raised together using boom hoist until boom reaches
desired boom operating angle. Luffing jib radius must be within capacity chart before
swinging over side of machine when raising over end of blocked crawlers.
Position boom at 85 degrees prior to lowering luffing jib. Lower luffing jib until boom to
luffing jib angle reaches value specified in table. Lower boom until luffing jib point is just
above ground. Position dolly under upper jib point, then lower upper jib point onto dolly.
Release swing brake (disengage swing lock) and continue to lower boom while luffing jib
rolls along ground until boom to luffing jib angle reaches 140 degrees. Keep enough tension
on luffing jib hoist to keep jib strut off luffing jib. Retract jib stop positioner cylinders (see
procedure). Continue to lower boom while luffing jib rolls along ground.
CAUTION: Do not under any condition allow boom to luffing jib angle to become less than
70 degrees.
