Recommended boom, luffing jib and fixed jib raising and lowering procedure:

14000 SERIES 2 must be equipped with 168,000 lb (76 200 kg) crane counterweight and 53,000 lb (24 040 kg)

carbody counterweight. Refer to fixed jib rigging assembly No. 179361 for makeup of inserts, pendants, strut, jib

stop setup and operation, and miscellaneous parts, etc. Refer to luffing jib rigging assembly No. A18387 for boom

and luffing jib make-up of inserts, pendants, struts, strut raising and lowering procedure, jib stop setup and

operation and miscellaneous parts, etc. Refer to Operator’s Manual for setup and installation.

Three methods may be used to raise and lower boom, luffing jib and fixed jib combinations, depending on

length:

A. Layout Jack-Knife Method With Fixed Jib Attached:

Caution: Anytime luffing jib or fixed jib point rollers are in contact with ground during raising or lowering

procedure, disengage swing lock and release swing brake.

Raising:

Boom, luffing jib and fixed jib are assembled in layout, end-to-end, position. Raise fixed jib strut and attach

pendants and backstays. Attach fixed jib stop to fixed jib butt and temporarily tie off to fixed jib strut. 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). Boom is then raised while luffing jib point and

fixed jib point wheels are allowed to roll on ground. Tension should be applied to luffing jib hoist to keep luffing

jib strut off luffing jib during boom raising. Boom up until boom-to-luffing jib angle reaches value specified in the

tables. Tighten luffing jib suspension with luffing jib hoist. Boom and luffing jib are then raised together using

boom hoist while fixed jib point wheel rolls on ground. Continue raising until fixed jib suspension tightens.

Attach fixed jib stop to luffing jib top. Boom, luffing jib and fixed jib are then raised together using boom hoist

until boom reaches desired boom operating angle. Fixed jib radius must be within capacity chart before

swinging over side of machine when raising over end of blocked crawlers.

Lowering:

Position boom at 85 degrees prior to lowering luffing jib. Lower luffing jib until boom-to-luffing jib angle reaches

value specified in the tables. Lower boom until fixed jib point wheels contact ground. Remove fixed jib stop from

luffing jib top and temporarily tie off to fixed jib strut. Lower boom as fixed jib point wheels roll on ground. Lower

boom until luffing jib point wheels contact ground. Continue to lower boom while luffing jib and fixed jib point

wheels roll along ground. Keep enough tension on luffing jib hoist to keep luffing jib strut off luffing jib. Stop

lowering boom when luffing jib stop pendants start to go into tension (approximately 168 degree boom-to-luffing

jib angle). Disengage luffing jib stop strut pins and lower boom to retract luffing jib stop inner strut. Pin strut in

retracted position.

B. Layout Jack-Knife Method With Fixed Jib Attached Before Luffing Jib Lift-Off:

Raising:

Boom and luffing jib are assembled in layout, end-to-end, position. Attach fixed jib backstay pendants to luffing

jib insert and place on ground. 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). Boom is

then raised while luffing jib point wheels are allowed to roll on ground. Tension should be applied to luffing jib

hoist to keep luffing jib strut off luffing jib during boom raising. Boom up until boom-to-luffing jib angle reaches

value specified in the tables. Tighten luffing jib suspension with luffing jib hoist. Attach fully assembled fixed jib

to luffing jib. Attach fixed jib backstays to fixed jib strut. Attach fixed jib stop to fixed jib butt and temporarily tie

off to fixed jib strut. Boom and luffing jib are then raised together using boom hoist while fixed jib point wheel

rolls on ground. Continue raising until fixed jib suspension tightens. Attach fixed jib stop to luffing jib top. Boom,

luffing jib and fixed jib are then raised together using boom hoist until boom reaches desired boom operating

angle. Fixed jib radius must be within capacity chart before swinging over side of machine when raising over

end of blocked crawlers.

Lowering:

Position boom at 85 degrees prior to lowering luffing jib. Lower luffing jib until boom-to-luffing jib angle reaches

value specified in the tables. Lower boom until fixed jib point wheels contact ground. Remove fixed jib stop from

luffing jib top and temporarily tie off to fixed jib strut. Lower boom as fixed jib point wheels roll on ground. Lower

boom until luffing jib point wheels contact ground. Remove fixed jib from luffing jib. Continue to lower boom

while luffing jib point wheels roll along ground. Keep enough tension on luffing jib hoist to keep luffing jib strut

off luffing jib. Stop lowering boom when luffing jib stop pendants start to go into tension (approximately 168

degree boom-to-luffing jib angle). Disengage luffing jib stop strut pins and lower boom to retract luffing jib stop

inner strut. Pin strut in retracted position.

Luffing Jib Raising Procedure

Fixed Jib No. 138 on Luffing Jib No.135 on Boom No. 76

C. Fold Under Jack-Knife Method:

Raising:

Boom and luffing jib are assembled in fold under position. Slowly raise boom; luffing jib point wheels will roll along

ground. When luffing jib hinge pin is 30 Ft. (9.1m) off ground, connect luffing jib pendants and fixed jib backstays. Place

fixed jib backstays on ground clear of luffing jib point wheels. Move luffing jib top wire rope guide to working position.

Tighten luffing jib suspension with luffing jib hoist. Slowly raise boom until luffing jib is vertical and luffing jib point wheels

are clear of ground. Slowly raise luffing jib to 10 degrees ahead of vertical with luffing jib hoist leaving wheels on ground.

Attach assembled fixed jib to luffing jib top. Attach fixed jib backstay pendants to fixed jib strut. Attach fixed jib stop to

fixed jib butt and temporarily tie off to fixed jib strut. Boom and luffing jib are raised together using boom hoist while fixed

jib point wheels roll on ground. Continue raising until fixed jib suspension tightens. Attach fixed jib stop to luffing jib top.

Boom, luffing jib and fixed jib are then raised together using boom hoist until boom reaches desired boom operating

range. Fixed jib radius must be within capacity chart before swinging over side of machine, when raising over end of

blocked crawlers.

Lowering:

Position boom at 75 degrees prior to lowering luffing jib and fixed jib. Slowly lower luffing jib until luffing jib angle

reaches 10 degrees ahead of vertical. Maintain 10 degrees ahead of vertical angle with luffing jib while lowering boom

until fixed jib point wheels contact ground. Remove fixed jib stop from luffing jib top and temporarily tie off to fixed jib

strut. Lower boom as fixed jib point wheels roll on ground. Maintain 10 degrees ahead of vertical angle with luffing jib

while lowering boom until luffing jib point wheels contact ground. Remove fixed jib from luffing jib. Raise boom slightly

and lower luffing jib to vertical. Slowly boom down and assist luffing jib point wheels in fold under direction. Continue to

lower boom while luffing jib rolls along ground. Boom down until luffing jib hinge pin is 30 Ft. (9.1m) off ground.

Disconnect luffing jib pendants and fixed jib backstays (if still attached). Move luffing jib top wire rope guide to stowed

position. Raise luffing jib strut with luffing jib hoist until luffing jib strut is in line with luffing jib. Lower boom and luffing jib

to ground.

Boom and luffing jib combinations in following table may be raised using fold under jack-knife method.
