6.4 LWG CABLE REEL LENGTH/ANGLE SENSOR REPLACEMENT PROCEDURE
MOUNTING
Mount cable reel on cab side of boom to ensure
adequate visibility. Length cable should spool
from the top of the drum.
NOTE:
Boom with a flat side: Use four (4) 2-inch hook bolts.
Trapezoidal Boom with a slanted side: Use two (2) 2-inch and two (2) 4-inch hook bolts.
There are four (4) ½” holes on the mounting plate.
1. Thread a nut onto the upper threaded part of the hook bolt, then place a lock washer and washer onto
hook bolt. Slide bushing on to free end (curved part) of hook bolt.
2. Insert the hook bolt into the holes in the cable reel mounting plate. NOTE: For a trapezoidal boom, the
4” hook bolts go into the top two (2) holes of the mounting plate.
3. Thread a nut onto the threaded part of the hook bolt, then place a lock washer and washer onto bolt to
fasten it into place. Repeat for each hook bolt.
NOTE: ALL WELDS MUST BE APPROVED BY THE CRANE MANUFACTURER.
4. Hold plate and hook bolt up to boom and affix to boom, by placing the inside curve of the hook bolts
facing outward. Mount cable reel to holes. Front of cable reel should be 1/8” closer to boom than rear.
(Front = 2-7/8”; Rear = 3”)
5. Adjust nuts up and down to tighten, and to mount the cable reel.
6. Plate should be parallel with boom.
INSTALLATION
1. Set pretension of the cable reel by turning the drum counter-clockwise 5 to 8 turns.
2. Run the length cable through the cable guides and wrap the length cable around the boom tip anchor
pin (4 or 5 wraps) and secure with tie wraps. Leave enough length cable to connect to boom tip
junction box.
3. Check the spooling. If spooling is not layered properly, carefully pull the cable out and respool the
length cable.
