NOTE The location of the sheave cluster (6) can vary depending on
reeving. See the Reeving Diagrams at the end of this section for
dead-end locations. See
Remove/Install Lower Boom Point
Sheaves on page 4-93.
The pendant (8) and dead-end link (9) have two uses:
• Tandem drum reeving. The pendant and link must be installed
around the sheave that is symmetric about the centerline of the
boom top with the dead-end link (7).
• They can be used to improve the block-up distance from the
boom top to the load block for single drum reeving.
The pendant (8) is stored in the boom butt. The dead-end link (9) is
stored in the parts box.
