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 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.

The document refers to luffing jib rigging assembly No. A18387 for detailed make-up of inserts, pendants, struts, and other components.

Usage Features

A. Layout In-Line Method:

Raising: Boom and luffing jib are assembled end-to-end. The boom is slowly raised until the luffing jib stop strut clears the ground. Luffing jib stop pendants are attached, and the inner strut is unpinned from its retracted position. The boom is further raised until the stop strut is fully extended and pins engaged (approximately 168-degree boom-to-luffing jib angle). Luffing jib suspension is tightened with the luffing jib hoist. Both boom and luffing jib are then raised simultaneously using only the boom hoist.
Lowering: The reverse procedure is followed.
Applicability (14000 SERIES 1, Without Boom Catwalks):
- Over End of Blocked Crawlers:
  - Boom Length (Feet/Meters): 65.6/20.0 to 134.5/41.0
  - Luffing Jib No. 135 (Feet/Meters): 70.0-170.0/21.3-51.8 to 70.0/21.3
- Over Side of Crawlers:
  - Boom Length (Feet/Meters): 65.6/20.0 to 114.8/35.0
  - Luffing Jib No. 135 (Feet/Meters): 70.0-170.0/21.3-51.8 to 70.0-80.0/21.3-24.4
Applicability (14000 SERIES 2 and SERIES 3, Without Boom Catwalks):
- Over End of Blocked Crawlers:
  - Boom Length (Feet/Meters): 65.6/20.0 to 164.0/50.0
  - Luffing Jib No. 135 (Feet/Meters): 70.0-170.0/21.3-51.8 to 70.0-90.0/21.3-27.4
  - Note: For 144.4 ft boom with 70.0-140.0 ft luffing jib, this combination cannot be raised using In-Line method when equipped with boom catwalks.
- Over Side of Crawlers:
  - Boom Length (Feet/Meters): 65.6/20.0 to 164.0/50.0
  - Luffing Jib No. 135 (Feet/Meters): 70.0-170.0/21.3-51.8 to 70.0-90.0/21.3-27.4

B. Layout Jack-Knife Method:

Caution: Disengage swing lock and release swing brake if luffing jib point rollers contact the ground during raising or lowering.
Raising: Boom and luffing jib are assembled end-to-end. The boom is slowly raised until the luffing jib stop strut clears the ground. Luffing jib stop pendants are attached, and the inner strut is unpinned. The boom is further raised until the stop strut is fully extended and pins engaged (approx. 168-degree boom-to-luffing jib angle). The boom is then raised while luffing jib point wheels roll on the ground. Tension is applied to the luffing jib hoist to keep the jib strut off the jib. The boom is raised until the boom-to-luffing jib angle reaches the specified value or vertical, whichever comes first. Luffing jib suspension is tightened, and both are raised together using the boom hoist until the desired operating angle is reached. Jib radius must be within the capacity chart before swinging over the side of the machine.
Lowering: The boom is positioned at 85 degrees. The luffing jib is lowered until the boom-to-luffing jib angle reaches the specified value. The boom is lowered until the luffing jib point wheels contact the ground. If the jib is vertical, it is raised a few degrees forward of vertical. The boom is continuously lowered while the jib wheels roll along the ground, maintaining tension on the luffing jib hoist to keep the jib strut off the jib. Lowering stops when the luffing jib stop pendants start to tension (approx. 168-degree boom-to-luffing jib angle). The jib stop strut pins are disengaged, and the boom is lowered to retract the inner strut, which is then pinned in the retracted position.
Applicability (14000 SERIES 1, Without Boom Catwalks):
- Over End of Blocked Crawlers:
  - Boom Length (Feet/Meters): 105.0/32.0 to 164.0/50.0

  - Note: When equipped with boom catwalks, this boom length requires wire rope guide assembly No. 177364 removal and lowerworks jacking cylinders attached.

C. Fold Under Jack-Knife Method:

Raising: Boom and luffing jib are assembled in the fold under position. The boom is slowly raised, allowing luffing jib point wheels to roll along the ground. When the luffing jib hinge pin is 30 Ft. (9.1m) off the ground, luffing jib pendants are connected. The luffing jib top wire rope guide is moved to the working position. Luffing jib suspension is tightened with the luffing jib hoist. The boom is slowly raised until the luffing jib is vertical and its point wheels are clear of the ground. Luffing jib suspension is tightened again. Both boom and luffing jib are then raised together using the boom hoist until the desired boom operating range is reached. The luffing jib radius must be within the capacity chart before swinging over the side of the machine.
Lowering: The boom is positioned at 75 degrees. The luffing jib is slowly lowered to vertical. The boom is lowered until the luffing jib point wheels are just clear of the ground. The boom is slowly lowered, assisting the luffing jib point wheels in the fold under direction. The boom is lowered until the luffing jib hinge pin is 30 Ft. (9.1m) off the ground. Luffing jib pendants are disconnected. The luffing jib top wire rope guide is moved to the stowed position. The luffing jib strut is raised with the luffing jib hoist until it is in line with the luffing jib. The boom and luffing jib are then lowered to the ground.
