I just bought a three section 60 ft crank up tower from a guy for 200.00. I plan on cranking this up to about 45 feet and hanging an Alpha Delta inverted V dipole, (80 through 6 meters) on it. The tower has a triangular hinge plate on the bottom which is connected to two of the tower posts with two bolts. This plate has three holes and it is supposed to bolt down to a concrete slab that you pour. The slab has three threaded rods ( that look like about 1/2 inch diameter) sticking up. I saw this at the guys house but we weren't going to try to take the slab. He said he had used about 5 bags of concrete but I'd feel better if i could see that in print...

To raise the tower you hinge the tower up (against your house I assume), although I understand that some of these are free standing without guy wires!!,(I don't know how that would be possible with my tower), and then insert the third bolt into the base. He told me that he then had this secured against the side of his house. I would do the same.

This tower has been sitting outside for a number of years, however the galvanized coating and cable is still good, and although the winch is pretty rusty the the gears and ratchet assembly still work. for safety purposes though I would really like to see the scoop on the winch, reversing mechanism and brake, and also the base.

I plan on lubricating it and installing this up against my house in the Spring, however I would really like to identify the manufacturer and perhaps get a manual for it. The problem is I can't find any clue on this thing at all as to who made it.

To see a representation of what this looks like please take a look at the LM354 on the following site. It looks very much like what I have, but I really don't Know for su

If anyone has any experience with one of these type towers I'd really appreciate any advice. Thanks very much, Lenny,

A-frame/sheer-legs are useful for this sort of activity

If you really need 2.2 cubic yards like your diagram says, you need about ninety 80 pound bags, not the 5 you mentioned. One bag is about 2/3 of a cubic foot, not yard; a yard has 27 cubic feet.

You'd be dumb to mix it. Delivered it's only about $100 - $150 a yard, if you can get a concrete truck to deliver a small quantity.

another place to look is "Rohn" towers.
crank up and tilt over

The PDF of the tower shows a base for a free-standing tower. You are not
putting up a free-standing tower if you attach it to a building. Your
challenge will be to get it positioned so you can attach it to the
building. What type of bracket do you have?

I just finished putting a short Rohn 25 tower against my pole barn shop.
I fabricated a new hinge base so I could tilt the tower up against the
barn with a flat side fastened to the wall. The Rohn hinge base would
have put a single pipe against the wall and my base allows two pipes to
be fastened to the wall.

Not being free-standing, you only need enough concrete in the base to be
sure it is below your local frost-line, so freezing water doesn't push
up the concrete. My base used 3 1/2, 60 lb bags of premix concrete. It
is not below the legal frost line, 3 ft, but is right next to the wall
and concrete floor of a heated shop. Be sure to add crushed rock to the
bottom of the hole for water drainage.
