Back-Pull/Stationery Reel - Puller Set-Up and Block Placement
Cable Puller Set-Up
Place an appropriate cable grip on each cable. Secure the grip to the cable with tape to keep the cable from
backing out of the grip should the pulling tension be relaxed.
Place a breakaway swivel between the pulling grip and the cable puller. An in-line dynamometer may be placed
there instead or along with the breakaway swivel.
Place the cable puller on the strand and close the puller gates to secure the puller to the strand.
Attach a pulling line to the cable puller. Pull the cable puller along the strand by hand or by winch (see next page
for winching notes). Place cable blocks to support the cable as it is pulled. The cable puller has an internal brake
which prevents the cable puller from moving backward on the strand when the pulling tension is released.
Do not overspin the reel - keep the cable wraps tight.
Cable Block/Corner Block Placement
Use a cable block lifter/lay-up stick to place cable blocks on the strand every 30 - 50 feet (9 - 15 meters).
Place corner blocks at all corners greater than 30° in the pole line. NEVER pull cable over the end rollers of
corner blocks as they will flatten and deform the cable.
At corners less than 30°, cable blocks can be placed on the strand several feet from and on each side of the
pole/line hardware. The cable blocks should allow the cable to move through the corner without undue bending
or drag.
