3. Pay out the rigging line by moving the Drum 0 control
handle forward.
4. Reeve the rigging line through the load block and boom
point sheaves and connect the rigging line to the desired
load line as shown in the Rigging Winch Assembly
drawing at end of this section.
5. Use the engine throttle to snug up the rigging line prior to
paying out the load line from selected load drum. Faulty
operation will result if there is slack in the rigging line
before engaging the automatic part of operation.
NOTE Use the engine throttle to increase and decrease
rigging winch line pull.

winch.
7. Move the Drum 0 control handle to off and push the
corresponding load drum control handle forward to pay
out the load line. The rigging winch will haul in rigging
line automatically.
NOTE The stall line pull of the rigging winch is regulated
with a proportional relief valve controlled by the
crane’s programmable controller.
8. Once the load line is reeved through the load block and
boom point sheaves:
a. Move the load drum control handle to off.
b. Pay out the rigging line to slacken the load line by
pushing the Drum 0 handle forward.

CAUTION!
Avoid Rigging Winch or Wire Rope Damage!
The rigging winch will not automatically pay out line if the
selected load drum control handle is pulled back to the
hoist position.
Structural damage to winch or rigging line will occur!
If it is necessary to haul in the load line on the load drum
when the load line is connected to the rigging line,
proceed as follows:
• Pay out the rigging line with the Drum 0 control
handle while hauling in the load line with the load
drum control handle.
• Keep the rigging line slacker than the load line with
the engine throttle.
WARNING
Flying Object Hazard!
Do not attempt to disconnect the rigging line from the load
line until the lines are slack.
The lines could fly apart with explosive force and
strike personnel.
