6.4 Aerial Installation
Back-Pull/Stationary Reel Method
Passing the Cable Puller at Poles
Pull the cable puller to the pole and release the tension in the pulling line. Pass the conduit 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 conduit through the
corner block.
Cable Block/Corner Block Placement
Place corner blocks at all corners greater than 30 degrees in the pole line. NEVER PULL CONDUIT OVER
THE END ROLLERS OF CORNER BLOCKS as they will flatten and deform the conduit.
At corners less than 30 degrees, 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 conduit to move through the corner without undue
bending or drag.
Power Winching Methods
Power winching a pull line to install conduit is a method often used when the pole line is obstructed or is in
extremely rough terrain because the pull line can be placed without tension concerns. In winching, the pull line
is attached to the cable puller and run along the strand. Roller blocks should be placed along with the pull line.
Once the pull line is run, it is attached to the conduit.
Carefully tension the pull line and begin pulling. Adjust the reel brakes to prevent undue pulling tension. Real-
time tension monitoring is required. Radio communications between the lineman observing the pull-out and the
winch operator is required. Intermediate conduit handling may be required as the pulling grips approach cable
and corner blocks.
