Mounting the Reels
No matter how you string the wire, you will have to
mount the reels on some support that allows them to
revolve freely. This is usually done by raising a reel on
reel jacks, as shown in figure 4-64. A metal rod strong
enough to support the reel is put through the hole in the
center, and the rod and reel are jacked up on each side
with the leg of the T-base away from the reel, as shown.
You may have to fasten down the bases of the jacks to
keep the strain from upsetting the reel. When you are
jacking up, it is necessary only to raise the reel just clear
of the deck.
When you are stringing wire in rough terrain, the
best method is to anchor a reel to the ground at the end of
the line by means of guys run to driven stakes. Then run
a rope line over the crossarms or through running blocks
mounted on the crossarms for a distance of 1,000 to
1,500 feet. This is accomplished by a lineman climbing
each pole and placing the rope in place.
After the rope has been strung over the crossarms,
one end is secured to the wires to be pulled, and a couple
of turns are taken with the other end around the winch
drum on the line truck. The drum is then rotated to haul
in the rope and the wires with it. As each wire passes a
crossarm, a lineman must climb the pole to set the wire
in proper position and guard against twisting.
To keep a paying-out reel from revolving too fast,
set a brake or drag against the reel. This can be simply a
board, held against the outer edge of the reel by a
helper. As a wire or wires are being pulled, enough crew
