CommScope Trunk & Distribution Cable - Manual (Page 24)

Back-Pull/Stationery Reel - Passing the Pole and Winching
Passing the Cable Puller at Poles
Pull the cable puller to the pole and release the tension in the pulling line. Pass the cable across the pole face
and the pole/line hardware, and attach the cable puller back to the strand. Place cable blocks on each side of
the pole.
At corner block locations, pass the cable puller to the opposite side of the pole and route the cables through the
corner block.
Cable Tails
A cable tail at least 3 feet (1 meter) in length should be left at the first and last poles and at all splicing locations.
More tail may be needed depending on the splicing that must be done or the size and location of the expansion
loop that will be made. Cap the end of the cables and tie them gently but securely to the strand. MAKE EVERY
EFFORT TO AVOID DAMAGE AT THE CABLE TAILS.
Power Winching Methods
Power winching a pull line to install CommScope cable is a method often used
when the poleline is obstructed or is in extremely rough terrain because the pull
line can be placed without tension concerns. In winching, the pull line is placed
in the cable puller and run along the strand. Once the pull line is run, it is
attached to the cable.
Carefully tension the pull line and begin pulling. Adjust the reel brakes to
prevent undue pulling tension. Real-time tension monitoring is required. Radio
communication between the lineman observing the pull-out and the winch
operator is required. Intermediate cable handling may be required as the
pulling grips approach cable and corner blocks.
