2.4.9 Repeat the tightening of the three cables with one
worker pulling as hard as possible on each cable as
another worker pushes the terminal fitting against the
fitting holder.
2.4.10 Make a small loop in each cable below the
fitting and secure the loop with a U-bolt cable clamp.
Position the U-bolt clamp 1/2" to 3/4" below the terminal
fitting. Securely tighten the nuts on the U-bolt clamp.
(See Figure 13) Cut off the excess cable leaving about
6 in. below the clamps. Tape the ends of the cables for
a distance of about one inch to prevent fraying.
2.4.11 Use a 5/8” torque wrench and rotate the winch
input shaft to approximately 40 Ft. Lbs. to put tension
on the cables. Check the terminal cable fittings to
insure that they have set properly. Cable should not be
pulled into the terminal cable fitting more than 1/4”.
CAUTION
If the cable has moved more than 1/4” through any of
the cable terminal fittings, the fitting has not set prop-
erly. Contact the Field Service Department. (740-345-
9631).
2.5 Completing the Pole-top Assembly
2.5.1 If the device is equipped with a bumper ring
instead of iris-type guide arms, proceed to paragraph
2.5.3. Otherwise, attach both guide arm spring brack-
ets to the ring. (See Figure 14) The double washers
must be installed between the brackets and the ring to
avoid possible interference with the luminaire mounting
brackets which will be mounted to the ring later.
Tighten each locknut until it is snug and then loosen it
about one half turn to allow the bracket to pivot.
2.5.2 Adjust the guide arms so the distance between
each wheel and the surface of the pole is 1/4 - 1/2 in. It
will be necessary to lift the ring to center the wheels
while checking the clearance between the wheels and
the pole. The adjustment is made by rotating the two
adjustment nuts on the ends of the two spring guide
rods. Use two wrenches to lock the adjustment nuts in
place by jamming them together tightly. (See Figure
14)
