Array Solutions Swinging Gate Side Mount

Congratulations.

You have selected one of the finest, and safest side mounts built for your antennas. We have strived to make this product very easy to assemble and also to be non-destructive on the tower.  For instance our use of thick cast aluminum saddles on the tower legs will assure you  that you will not crush or dent a tower leg. Care has been taken to chose the finest parts available. We used a CAD program to assure all parts fit exactly and precisely as planned.

Hardware List, please count and make sure you have the following

NOTE : check the holes in the parts for galvanization fills.  Use a punch hammer, and a rat tail file to clear any excess zinc.

Assembly instructions

Bolt together the rotor/bearing plate and tower arm assembly. The Tower Arm assemblies are the 2 inch angle iron arms with slotted holes in them.  Use four of the 3/8 -16 X 1 inch bolts, washers, split washers, and nuts. Fig. 1 has the finished cross arm picture. One cross arm you will notice has a flange welded to it to allow the plate to be bolted at the correct height to keep it horizontal on the tower.  You may bolt your rotor onto the plate at this time. Or you may bolt the rotor in after the side arms are mounted to the tower.

Bolt the bearing plate onto two of the crossed tower arms as you did for the rotor plate.

Since the bearing plate and the rotor plates are identical they will look exactly the same. 

Bolt the block bearing on top of the bearing plate as in fig 2.  and fig 3. Use the 1 1/4 inch bolts and hardware for the bearing block since it is quite thick.

                                                        Fig. 3

Next built the swinging gate with the remaining four pieces. The horizontal arms are straight cut on the ends and the diagonal braces have a miter cut on their ends.  Put them together with the remaining 3/8-16 bolts using the 1 1/4 inch  larger bolt in the center.  Put two flat washers in the center of the diagonal braces first to space the diagonals properly. Use figure 4 as a guide.

                                                    Fig 4.

Notice how the diagonals are mounted above and below the horizontal arms. The holes on the right are for the 2 inch U-bolts, saddles, and mounting hardware. Place your 1.5 inch (1.9 inch OD) water pipe mast inside the U-bolts and tighten either on the ground or up on the tower later.

The holes on the left of figure 4 are for the remaining 2 2 inch U-bolts saddles and antenna Mast.  Use the inside holes for ROHN 25 and the outside holes for ROHN 45 Towers.

Assembly on the tower

Hoist the Rotor plate to the desired position with or without the rotor mounted. Mount the cross arms to the tower through the appropriate holes in the cross arms.  Use the saddles with the U-bolts as in figure 5.  The U-bolts supplied should be the exact ones for your tower. Do not use over sized U-bolts and saddles.

                                    Fig. 5

You may mount the rotor at this time with it's bolts and hardware if you have not already done so.  Loosen the mast plate so you can insert the mast easily later.

Next mount the bearing arms as above and using the remaining 4 U-bolts and saddles.  Place the bearing plate arms at the desired height above the rotor plate arms.  You can determine this by the length of your mast.

Finally hoist in place the swinging gate side arm with both masts mounted on it.  Slide the rotor mast up into the bearing and down into the rotor. Tighten the rotor mast plate with the side arm pointing in the correct direction.  

Some installers pin the mast into the rotor and some do not.  If your installing this fixture you probably already know if your going to pin or not.  Call us us you wish to discuss the pros and cons of doing this.

Haul up your beam and hook up the rotor!  Your Done.

The Side mount may be use to turn multiple beams on a very long rotor mast.

We can supply bearing plates and tower cross arms for these installations.  For instance you may have a large rotor mounted near the ground and a 42 foot rotor mast held in place with 3 bearing arms. This could allow several beams to be mounted with their own swinging gates.
