[SCCC] tower climber

[Drew Arnett]

Yes the tower should not be saved.  Want to remove with first priority
human safety, 2nd the house it's attached to, and we'll let whatever
fall where it does.

Whether it's allowed to tip away from the house and just fall or if we
have a line on it to control the descent, the concern is that the base
can't kick and cause damage.  The corrosion is likely limited to the
very bottom.  The hinged base plate looks solid as well as the single
(no backup!) bolt that anchors that to the concrete base.  The hinge
pin looks solid.  The hinge might be solid on one side (must probe to
know!).  Same side one of the 3 tower legs looks (we don't bank on
looks) solid.  So, it might be safe to lower as is, but I'd much
rather crane it out or put a solid backup anchor in the ground at the
base to provide a safety.

Thanks for the suggestions!

A tower guy recommendation is what I should have askedfor, not a climber.  Definitely nobody should climb this thing.  Lookslike the rust problem is at the bottom and so is limited so the craneidea is a good and safe one.  It's on the back of the houseunfortunately so would need a crane large enough to go over the house.(Not uncommon, but I haven't rented one myself.  I have used genielifts, but it's been a few years.)And this isn't a tubular; it's a triangle 2 section nested tower.Fairly small.  I should have measured the size of the section, butit's definitely not bigger than rohn 25 and maybe a tad smaller.Thanks,Drewn7daOn Fri, Apr 16, 2021 at 2:03 AM NA6MB Mike <na6mb.mike at gmail.com> wrote:>> I don’t think you need a tower climber, you need a crane.> That would be the safest way to remove a rusty tower.> Rig a cable above the balance point, unbolt or cut the bottom and lift it away and lower to ground level.> You may be able to use a bucket lift.> Remove the antennas and rig to lower the tower tube.>> NA6MB> Mike>>>> Sent from my iPad>> > On Apr 15, 2021, at 7:48 PM, Drew Arnett <arnett.drew at gmail.com> wrote:> >> > I saw a referral some time back, but don't have the info.> >> > Looking at a 2 section telescoping & hand winched tower at a SK home.> > Very solid bracket at the eaves, but the tubing at the foot is at> > least partially rotten.
