OT tower disassemble tool

I have to take down a 60ft Rohn-25 tower that's been up for 20 plus
years. I remember seeing a tool advertised in QST and CQ for just this purpose. It resembled a long "lever" that was dimensioned for Rohn-25 specifically and helped to pry the sections apart. Any leads to this "tool" would be greatly appreciated. Thanks in advance. ...robert -- Robert G Strickland, PhD ABPH - KE2WY [hidden email] Syracuse, New York, USA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

I remember seeing that tool in magazine ads. I have a modified light weight
scissor jack to loosen tower sections. It loosens all three legs at the same time. It works very well. If you don't find the rohn tool you might consider the jack. 73 Joe K2UF -----Original Message----- From: Elecraft [mailto:[hidden email]] On Behalf Of Robert G Strickland Sent: Monday, October 13, 2014 10:26 PM To: Elecraft Subject: [Elecraft] OT tower disassemble tool I have to take down a 60ft Rohn-25 tower that's been up for 20 plus years.

I use a small bottle jack and a pair of 2x4 all tied together and then
tied to a tower leg. This protects those below if something slips.

The original Tower Jack is no longer made. A newer/better design is
manufactured by KF7P Metalworks: http://www.kf7p.com/KF7P/YellowJack.html Called the "Yellow Jack". That said, be EXTREMELY careful disassembling an old tower, particularly one that you may not know much of its history or if it was installed properly. Be sure you check the integrity of the tower itself AND the guy anchors/guys. The safest way to take it down may be with a crane. If you can..a sawzall/torch may be a better solution. Be safe and understand what you're doing. I would check the Towertalk archives on this subject. On 10/13/2014 9:35 PM, Dr. William J.

Are you actually going to climb Rohn 25 that has been up in the air for 20+
years, for disassembly? Consider taking the thing down with a crane, supporting it at the top with the crane and cut the bottom off, then lay it down with the crane. As soon as you loose the top guys there are all kinds of age-related things that can go wrong down below. You should take this subject onto the TowerTalk reflector. 73, Guy K2AV On Mon, Oct 13, 2014 at 10:26 PM, Robert G Strickland <[hidden email]> wrote: > I have to take down a 60ft Rohn-25 tower that's been up for 20 plus years. > I remember seeing a tool advertised in QST and CQ for just this purpose.

I have always used temporary guy wires whenever I had any doubts, not
only during removal but also during installation of a tower. As long as the tower is well-guyed it's not going to fall down. The trick is to guy it just below the section you're working on. As you add/remove each section, move the guys up or down a section. A little tedious but worth the trouble.

All it takes is ONE rusted out telescoping joint between sections. The
install could have been textbook, and you could still have a rusted telescoping joint. Rohn 25 is the low end, minimum metal, inexpensive tower. Rohn 45 and 55 are far more robust. Take this subject to TowerTalk reflector and see how many horror stories you dig up. If a tower joint kicks out sidewise between guys below, rope guys won't necessarily save you. There are stories of towers collapsing straight down, inside the guys, with all the guys below still attached. When you plan for the worst, then you don't get killed, maimed or crippled by the worst. Why would anyone bet the rest of their life on old Rohn 25? Own stock in the company? Use a crane to take down old Rohn 25, or if you got the space, cut it down like a tree by cutting the guys opposite the desired direction of fall. May you live long enough and healthy enough to play video games with your great-grandchildren. 73, Guy.

> Be sure you check the integrity of the tower
>> itself AND the guy anchors/guys. Amen to that. One of the local guys was seriously hurt when a tower he was taking down fell with him on it. One of the turnbuckles parted. The widow said the husband used only stainless steel hardware. This turned out to not be true. And keep in mind that towers made with tubing rot from the inside out. You can't check the outside and know if the tower is in decent shape. A local ham, as well as business-band tower owner, looked up at his tower one day and saw that one leg was bowing out. This was tubular tower as in the Rohn 45 or 55 stuff. He replaced it with a tower made from solid rod. There is no 'inside' to rot with solid rod. Since one cannot see the inside of a tower leg, and since tubing rots from the inside out, it is good to be cautious. If I were going to climb an old tower I would guy it securely every 10' on the way up. I dunno that that would prevent it from collapsing, but it would go a long ways toward preventing that. Old tower is dangerous stuff. 73 de dave ab9ca/4 On 10/13/14 9:51 PM, Gary K9GS wrote: > The original Tower Jack is no longer made.

Assuming the tower is completely unsafe could result in an unnecessary
crane bill. Assuming the tower is completely safe could result in an unnecessary medical bill. Easy choice.

Thanks for all the info. For those who expressed concern for safety and
for myself, I initially erected the tower, and to the best of my knowledge did all the right things. I've been climbing it regularly for the whole 20 years with no mishaps. Time and season dictate that I have a commercial rigger take it down. This person, somewhat as a surprise, said he was going to lift the tower away from the house [it goes through a porch floor/roof and is bracketed to the roof peak] in one piece and lay it on the ground. Once on the ground it will be my job to pry the sections apart. As most noted, this will not be easy, and thus my interest in the "tool" or any similar method. With the tower on the ground, I imagine it will be somewhat unwieldy, so the "tool" may be the best bet. When the rigger heard about the "tool" he commented that it would probably be a handy thing to have on hand. I'll be off the air for a while getting set up in the new house. A vertical will probably be an interim antenna until some time next year when I can start with a new tower installation. Any comments on prepping the old tower sections for a new lease on life? Again thanks to all who replied. ...robert On 10/14/2014 02:26, Robert G Strickland wrote: > I have to take down a 60ft Rohn-25 tower that's been up for 20 plus > years.
