6.2 Aerial Installation
Back-Pull/Stationary Reel Method
Back-Pull/Stationary Reel Method
The back-pull / stationary reel method is the usual method of aerial conduit placement. This method is also best suited
for locations where the strand changes from the field side of the pole to the street side of the pole and where there are
excessive obstacles to work around. The conduit is run from the reel up to the strand then pulled in a direction away
from the reel and is held aloft by the cable blocks and rollers. Once the section of conduit is pulled into place it is
lashed and then cut.
Set-Up Chute Placement
The set-up chute should be positioned on the first pole of the conduit route or attached to the strand at the first pole.
Placement of the set-up chute should keep the conduit from rubbing on the reel or pole. Either a 45 degree or 90
degree corner block may be used as a set-up chute.
Trailer Set-Up
The trailer should be positioned in-line with the strand and twice the distance of the set-up chute to the ground from
the set-up chute. This prevents the conduit from rubbing on the pole or reel or binding on the chute. If the trailer
cannot be positioned there, move the set-up chute and the trailer to an adjacent pole.
The conduit should pay-off the top of the reel. The pay-off of the conduit from the reel should cause a downward force
at the hitch of the trailer.
Chock the trailer wheels. Adjust the reel brakes as needed. Place protective barriers and cones as needed
to protect pedestrians.
