16. Test the anti-two-block circuit for proper operation and
hydraulic circuit cut out.
Alternative #2
This method requires pushing a long rod through the
boom to pull the new anti-two-block wire through the boom.
This method is required in the event the anti-two-block wire
is severed.
Special tools and equipment:
• Electrical tape
• Rod or electrical conduit 30 ft (9,1 m)
1. Retract boom completely.
2. Unplug electrical connector at sheave case end of
boom.
3. Remove electrical connector from the anti-two-block
wire running to the reel.
4. Remove the capscrew, washers and nut, anchoring the
anti-two-block wire at the sheave case end of the last
section.
5. Insert the rod or conduit into the sheave case end of the
boom and push through the full length of the boom. On
the five section boom the rod or conduit must be routed
thru the guide loop on the extend cylinder sheave case.
This can be verified by looking inside the fully retracted
boom, viewed from the sheave case end.
6. At the hoist end of the boom, the rod or conduit will be
below the roller guides at the backs of the extending
sections.
7. Lift the rod or conduit and pull it out the back end of the
boom about 1 ft (0,3 m).
8. Install the new anti-two-block wire on the reel.
9. Route the new wire through the sheave case at the hoist
end of the boom and through the roller guides on the
back end of each extending section.
10. Pull the anti-two-block wire out the hoist mount end of
the boom and tape securely to the rod or electrical
conduit. This will still leave the anti-two-block wire routed
through the roller guides.
11. Draw the rod or electrical conduit plus an additional
length of anti-two-block wire long enough to install the
thimble from the sheave case end of the boom. Install
thimble per instructions out of the sheave case end of
the boom.
12. Attach the thimble to the capscrew retainer anchor in the
sheave case.
13. Allow the reel to retract the thimbles into the boom.
14. Attach the electrical connector and connect to the
switch.
15. Slowly operate the boom to make sure that the anti-two-
block wire runs freely in the boom and that the cable reel
runs properly.
16. Test the anti-two-block circuit for proper operation and
hydraulic circuit cut out.
