ACOM CM-10 Antenna Crank-up Mast

lower the winch so that lower tube and the lifter get in the pivot at the mast base, and the rope of the

winch gets into the lifter pulley. By means of the winch lift the lifter together with the lower tube until the

fixing pins enter the fixing holes.

Attach the upper guy ropes to the upper guy strap and orientate them toward the guy ropes anchor points.

When you use a rotator, cut the tube at the tip so that you can mount the rotator. Pay attention that the

antenna should be mounted on the fixing bushing as close as possible and by no means more than 400

mm from it including rotator (Fig.3).

Mount your antenna on the so orientated mast tip. Тhe antenna must be fixed at the desired azimuth

as precisely as possible. No azimuth corrections can be made later.

By means of the hand winch the mast lifting is continuing until the next hole for the support pin passes

through the upper strap. Insert the support pin into it, let the mast settle on it, and remove the lifter.

Insert the two M10x100 bolts into the respective holes (Fig. 5) in order to fix the two tubes together.

Tighten well both nuts, paying attention not to overdo and damage the bolts threads. After the bolts are

placed, put the next tube (No 8) in the way described above.

Place like-wise tubes No 7, No 6, and No

When you start lifting tube No 5 and remove the securing

pin from tube No 6, put bolt M10x100 into the hole so that it supports the lower strap as shown in Fig. 5.

Attach the lower set of guy ropes to the strap and orientate them toward the anchor points.

After you have mounted the lower strap and the guy ropes, put the two M10x100 bolts that fix tube

No 5 and tube No 6 together.

Continue mounting of tubes No 4, No 3 and No 2 similarly as described above.

After that place the last tube (No 1), remove the support pin from tube No 2, and lower the mast until

the lifter settles on the base. Then mount the respective fixtures as shown in Fig. 6.

Adjust all mast guy ropes so that the mast is vertical, remove the upper pulley, rope and winch and

store them to prevent them from damage and corrosion.

Dismantling of the mast is carried out in reverse sequence of the described above.

3. OPERATION IN NORMAL CONDITIONS

No other structures should be attached to mast and antenna.

4. OPERATION IN EXTREME CONDITIONS

No mast operation is allowed in conditions beyond the technical characteristics.

If severe aggravation of operating conditions is anticipated, measures should be taken to prevent

accidents in case of structure crash, including partial or full folding or uninstalling.

5. MAINTENANCE

In order to keep the structure in good technical shape and avoid faults during operation, annual

maintenance is required.

The minimum maintenance includes:

- Inspection of all structure parts for absence of faults and deformations.

- Inspection of all guy ropes and re-adjustment of their strain if necessary.
