Instructions
1
If the boot is located in a pit, the leg in
the pit must also be laterally (horizontally)
braced. The leg may be braced near ground
level (work floor) to obtain maximum head
clearance on the first set of cables above
the ground level.
2
Before setting the leg on the boot,
be certain that the head section is in
an exact plumb position to the boot.
Use a transit (or transits) to check its
position.
Use a bead of caulking at the
flanges and set the leg into position. Bolt
the flanges together.
3
Connect each guy cable to its anchor.
See
pages 31 - 32
. Start connecting the
lower set of cables first and progress
towards the top. Locate a turnbuckle in
each cable at a convenient distance from
the anchor. Extend the turnbuckles as
far as possible for later adjustment. See
for anchor and cable
clamping information.
4
Use (2) transits to keep the leg straight
and plumb when tightening the cables.
Locate (1) transit in line with (1) row of
anchors and about 50’
[15,240 mm]
further
away from the leg than the furthest
anchor. This transit will be used for
adjusting cables extending to the right and
left of it. Set a second transit 90 degrees
from the first transit in line with the second
row of anchors to adjust cables extending
in the other (2) directions. When
plumbing the leg, tension the cables to
600-700 pounds
[273-317 kgf]
.
5
Tighten (2) opposite cables on the same
level together. Keep the leg straight when
tightening the cables. This will balance
the tension in the (2) cables. Tighten all
(4) cables at each level before proceeding
upward to the next level of cables.
6
A final recheck on the plumbing is made
with a plumb bob.
If the leg is not
perfectly plumb, there can be difficulty
experienced with the belt not running
true.
Insert a plumb bob into the up leg
section from the head section. Lower the
plumb bob past the inspection door. Tie the
plumb line to a cross board over the top of
the head frame. Locate the line so it clears
all sides inside the leg. Note the position of
the plumb line at the top end and bottom
end.. The distance to the sides of the leg
must be the same at the top and bottom. If it
is not the same within 1/2”
[13 mm]
, readjust
the guy cables. Readjustment of the transits
may be helpful to maintain the straightness
of the leg.
NOTE:
Either end or the center of the
turnbuckle may turn and loosen the cable.
One method of securing the cable is to lace
a short length of cable through the ends
and center of the turnbuckle and secure
the cable with cable clips. This also deters
children and other unauthorized persons
from loosening the cables.
NOTE:
Most contractors lift the uppermost assembly
section by looping a nylon choker or other strapping
device around the shaft. Also, wiring or attaching the
hood while lifting the uppermost assembly section will
eliminate a separate lifting of the hood.
WARNING!
After all cables have been tensioned
and the leg rechecked for plumb and
straightness, secure the turnbuckles to
prevent turnbuckles from loosening!
