Recommended boom and luffing jib raising and lowering procedure.
Machine must be equipped with 492,000 lb (223 170 kg) crane counterweight,
320,000 lb (145 150 kg) carbody counterweight and 0 lb (0 kg), 247,800 lb
(112 400 kg), 467,800 lb (212 190 kg), or 599,800 lb (272 060 kg) hanging
counterweight. Refer to luffing jib rigging assembly No. A08238 for boom 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.
