Jib Operation EEC-0044 V1.1
Jib Operation
J. When the jib is stowed, the boom cannot be fully retracted if a boom tip
attachment option is installed.
K. For manually extendable jib options:
1. Extension retaining pin ‘E’ must always be installed before operation.
2. All swing around (stow and unstowing) operations shall be done with jib
retracted and pinned.
3. Extendable section may slide out of 1st section jib when pin ‘E’ is
removed. Keep personnel clear of area.
Deployment Procedure
A. Using boom telescope function, fully retract boom.
B. Using lift function, lower boom to allow for easier access to jib deployment pins
‘C1’ and ‘C2’.
C. Install pins ‘C1’ in upper and lower jib ears. Install retainer spring clips. These
pins will be used as a pivot point to swing jib into the deployed position.
D. Locate the stowed position of pins ‘C2’. If in jib attachment holes or boom sheave
case jib holes, remove pins from storage location.
E. Remove jib-swing pin ‘B’ from top ear of jib.
F. Remove stow pin ‘A’ from ramp/side stow bracket assembly on jib.
G. Attach tag line to sheave case end of jib.
H. Using lift function, raise boom to a horizontal position.
I. Using telescope function, slowly extend boom approximately one foot. This will
pull the jib out of the stow bracket.
Use Caution during this step. The jib is free to swing away from the boom upon
boom extension.
J. Using tag line, swing jib into deployed position.
K. Remove cable keeper pins from boom sheave case and jib. Remove hook block.
