2.1 Pole Preparation
2.1.1
See pole supplier or contact Holophane Cus-
tomer Service to obtain instructions for proper pole
preparation and pole assembly.
CAUTION
Improper pole assembly will adversly affect the opera-
tion of the lowering device. For proper operation, the
pole sections must be completely seated before
installation of the lowering device.
2.1.2
During or after assembly of the pole, string a light
rope, wire or cable through the pole to aid in pulling
hoisting and power cables.
2.1.3
Orient the pole so that the handhole is facing up,
and support the pole without sag with the top end at
least three feet above the ground.
2.2 Installing the Headframe and Mounting Ring
Assemblies and Stringing the Hoisting Cables
2.2.1
Place the lowering device crate near the top of
the pole. After removing the top and sides of the
carton, remove the headframe assembly by lifting it
from the mounting ring assembly. Lift in one move-
ment, keeping the headframe plate level; otherwise, the
latches may catch. Place the headframe assembly
near the top of the pole on a clean surface.
2.2.2
Slide the LD ring over the top of the pole and
about 4 ft. down. (See Figure 1) The iris-type guide
arms or the bumper ring should be oriented toward the
bottom of the pole.
2.2.3
Unpack the junction box with the main power
cord and place near the top of pole. Uncoil the power
cord halfway down along the pole and back to the top.
Uncoil in a manner that will not leave the cord twisted.
2.2.4
Unpack the clevis assembly with the hoisting
cables and place clevis near the bottom of the head
frame. Uncoil the cables, (hand over hand), without
twisting, laying them along side the pole. It is helpful to
place the clevis inside the pole top during this opera-
tion.
CAUTION
The cables must be carefully rolled out straight, (hand
over hand), as if pulled from a reel; otherwise, they may
coil and kink when pulled tight, resulting in cable
damage.
2.2.5
Securely prop the head frame on its edge with
the large power cable slot oriented up. The head frame
must be fully supported while pulling cables to prevent
it from falling over and potentially causing damage.
2.2.6
Thread one of the hoisting cables up through one
of the small round holes in the cable divider plate inside
the headframe assembly (See Figure 2), then over the
top of the two sheaves in the sheave bracket and down
through the latch barrel. Do not allow the cable to go
outside the cable keepers on the outside edge of the
sheave. (See Figure 3). Pull the cable, to remove the
slack, with the clevis positioned near the bottom of the
triangular slipfitter.
