4

CM106BK Tripod Kit

WARNING

5. Attach each leg assembly to the tripod body using two 5/16-18 x 2.00 in.

bolts and lock nuts. Do not over-tighten the bolts. The tripod legs and leg
braces must be able to pivot.

2.2 Tripod Base Positioning

Tripod installation near power lines is dangerous. The
minimum safe recommended distance from overhead
power lines is 1 1/2 times the height of the tripod and
mast combined. Call your local utility providers to
locate buried utilities prior to installation.

The tripod base has three legs, which are individually adjustable, that allow the
tripod to be installed over non-level terrain.

Prepare the area where the tripod will be installed. The tripod requires an area
approximately 3.4 m (11 ft) in diameter. Natural vegetation and the ground
surface should be disturbed as little as possible, but brush and tall weeds should
be removed.

Stand the tripod base up on end, and rotate the feet perpendicular to the legs.
Each leg has a clamp bracket with a bolt that locks the leg in place when
tightened.

5

CM106BK Tripod Kit

2.2.1 Mounting on a Relatively Flat Area

2.2.2 Mounting on an Incline

Loosen one clamp bracket bolt at a time and extend each leg until the three legs
are at the same extension. With the legs extended, orient the tripod so that one
of the legs points South (assuming the instrument enclosure with –MM Mast
Mount bracket will face North). If the instrument enclosure has the –LM Leg
Mount bracket, orient the tripod so that the enclosure will mount to one of the
three leg mount positions on the tripod, facing the desired direction. The tripod
is typically plumbed after the mast has been installed, as described in Section

2.3, Mast.

Loosen the bolts on the clamp brackets. With the legs extended, orient the
tripod so that one leg points downhill and the other two legs point uphill. The
tripod is more stable with only one leg pointed downhill because the mast is
closer to the center of the footprint (see FIGURE 2-2). Tighten the bolts on the
clamp brackets to lock the legs in place.

The tripod is typically plumbed after the mast has been installed, as described
in Section 2.3, Mast.

6

FIGURE 2-2. Tripod with one leg pointing downhill

2.3 Mast

Slide the mast into the tripod base orienting the end with the hole upwards,
making sure that it extends below the lower bolts and rests on the tripod body
tabs. Tighten the six 5/16-18 x 2.25 in. bolts to secure the mast.

Plumb the tripod by adjusting the northeast and south facing legs (use the
downhill leg and one of the uphill legs when the tripod is installed on a slope).
With a level on the East side of the mast, adjust the Northeast leg for plumb.
With the level on the South side of the mast, adjust the South leg for plumb.
Tighten the 5/16 bolt on each clamp bracket after the adjustments have been
made.

2.4 Installing the Optional Guy Kit

Guy Collar

Guy Wire

Guy Bracket

Part 29813, CM106B Guy Kit, can be ordered separately for areas that
experience high wind speeds (Section 4, Specifications). Install the guy
brackets to the mast as shown in FIGURE 2-3. Attach the three guy wires to
the guy collar and slide the collar over the mast so that the collar butts against
the brackets.

CM106BK Tripod Kit

FIGURE 2-3. Guy collar

On the end of each guy line is a case and hardware to attach to the turnbuckles.
Unscrew the turnbuckles so that only 1/2 in. of thread extends beyond the
inside of the turnbuckle body. Attach the case and turnbuckle to the tripod leg
as shown in FIGURE 2-4. Loosen the two clamp nuts, and remove the slack in
the guy line by feeding the load end of the guy wire through the case while
pulling up on the free end.

After the slack has been removed from the guy lines, tighten the clamp nuts,
and then tighten the turnbuckles to the desired tension.

2.5 Staking the Tripod Feet

Six stakes are provided for securing the tripod feet to the ground. Drive two
stakes through holes in each foot at an angle as shown in FIGURE 2-5.

Stakes may not be adequate depending on soil structure, maximum wind
speeds experienced at the site, mast height, or wind load from the
instrumentation. For questionable situations, additional stakes (pn 17049) or
even concrete footings for the tripod feet and guy anchors should be
considered.
