8) Tower Raising Options
There are various options for the raising and lowering of a tilt-up tower. The
towers are equipped to be raised and lowered with a vehicle, such as a truck or
tractor. They come with a hoist cable and pulleys for raising with a vehicle. The
ideal vehicle is a heavy pickup with 4 wheel drive and an automatic transmission.
However, there are situations where this is not a viable option.
The other common means of raising a tower is the use of a hand or electric
winch or a “grip hoist”. An optional hand winch that is setup to be driven with an
electric drill and other winches are available from ARE.
Whatever the hoisting method, make sure that it is rated for the load. The 85 foot
tower requires 3,000 pounds and the 64 and 43 foot towers are 2,000 pounds.
This is for a straight pull. Pulleys will reduce the force and increase the cable
length required.
9) Tower Assembly
Step 1 (Base Installation and Anchor Setup)
Base Installation- The start of the tower assembly begins with the base plate.
Mount the base plate on the bolts in the center tower foundation and level it. Use
5/8” nuts on the base bolts under the base plate and adjust them to level the
base. Next, install the base plate with a 5/8” washer, one on each side of the
plate, and a 5/8” nut on top. Tighten the nuts and check for level. If it is not
level, readjust until it is level. When you have it level, use a non-shrinking grout
under the base plate to make a solid support. (See drawing D9 and Figure 2)
Anchor Set Up- Attach the equalizer plates (uneven triangles with holes) to the
side and down anchors. Use the 1/2” shackles provided and make sure that the
pointy end of the equalizer is pointing toward the ground. (See Figure 3) Attach
the jaw side of the Jaw & Eye Turnbuckles 1/2” x 12” to the equalizer plate. Start
with the lowest hole and work up, except always put the last turnbuckle in the top
hole. There is one turnbuckle for each tower section, for example the 64 foot
tower will have 3 turnbuckles. Adjust the turnbuckles so that they are a little
more than half way open. Do this for the left, right and down side foundations.
