skin a cat

[bren guzzi]

There are loads of ways to skin a cat.
How would you guys tackle this problem ?
The pole on the right is rotten. You can get a tracked bucket truck to the poles. The line is dead. No cranes or hoist to lift any thing. The bucket can only lift "a man" ... SO how do ya change the pole on the right. Not a great pic but its an intermediate pole ( straight through). We've a digger to take the old pole down and put the new one up. I know how we do it. :) what about you guys. ????????????

[RadonHuffer]

Even if it was off the original structure a bit in the end, Then I would tie the old broken pole to the new one for a while till I was sure it was safe and to take pressure off the steel frame work and cross arm.

The hard part is over IMHO.

[bren guzzi]

While your doing that ........ We would have changed it out.

Have changed one in less than an hour. ( 47 minutes. ).

I will let ya guys work it out. Time for. Zzzzzzzzzz up here. :)

[RadonHuffer]

Ya I bet it could be done. I am use to building new.
So I would play safe like dropping an old farm Silo.


I would love to see how its done.;)

Ummmmm set new pole as close as possible to bad un.chain em together, drop right side conductor to make the arm manageable, detach the arm and bracing from bad pole ,use a comealong if necessary between the 2 good poles to move new pole to where the thru bolt will align and restab arm.Reattach outside conductor,cut the old pole out in sections or fall it down the line, reattach bracing, and have me a bananna

Sorry poot.( Your right about the banana though.). If ya did that the arm would be out of twist. Gotta put the new pole where the old one was. :(
Ya could have done it by now. :)

Changed hundres of these single rotten poles in a H pole set. Got it down ... Pity we are changing both of these or I'd do it an show ya pics. But I will explain in the morning.

Nite ... ZzzzZzzzZzzzz...... :)

My 12 year old has been watching this puzzle and even he likes it.

Dropping the right conductor would take off lots of weight so would all those bells.

I am so use to rotten cross arms my thinking is they mostly get changed out but that could vary with geography?

[dooghi]

How about taking the guy wires (stays) off the right pole and temporaly attach to arm on left side. Unbolt X bracing, and crossarm, and pull old pole and set new pole reattach crossarm and X bracing and guy wires. Then go home.

[Pootnaigle]

Ummmmmmmm I suspect that Arm is angle iron or sumpin similar........ not wood. I am absolutely not seeing a twist of any kind happening to the arm.

[THE KID]

drop the outside phase on the right side down to the ground. I'm asuming the spans are far enough apart that it will reach the ground or close to it. Move middle phase to good pole and tie it there. Undo hardware pull old pole. Set new pole fasten hardware to new pole move middle phase back put outside phase back up. The other outside phase will help hold the arm level.

[bren guzzi]

Steel x arm.

Ok what ya do is you attach a tirfor to the bottom of the pole on the left with a sling. Run the bond up to the x arm and attach the bond to the farthest part of the arm on the left. Take up on the tirfor . With not to much pressure.the weight will come of the bolt on the rotten pole. You can then take the bolt from the rotten pole. Drop the old one and set the new one in the same place. New bolt in and your done.
And before you ask. YES the pole on the left will easily take the extra weight. It looks odd when the wires and x arm are supported by one pole..... But trust me it works.

[RadonHuffer]

A little clarification please.:D

[T-Man]

Similar to a jack.

What do you anchor the Tirfor to. The other pole butt or do you set an anchor and trust it?

[aviewfrom]

A little clarification please.:D

Tirfor = kinda like a come-a-long. If I'm following correctly you attach the tirfor to the bottom of the left hand pole and attach the cable to the left edge of the x-arm. Tighten to take off the pressure on the right hand pole, unbolt, and pull out. Set new pole in it's place.

I had the concept right. Just used the stays instead of the pole butt.

[Pootnaigle]

Ummmmmm and thats spozta keep the arm from a twist? I dont think so.There is gonna be way more strain on that arm doing it your way.With no insulators or conductor on the outside The arm would only be slighty outta balance and I would think manageable .

[RadonHuffer]

Nice Drawing exactly what I was thinking.

If its a very long span we might drop the outer wire. And even move the centre one towards the "good leg. But rarely have to.

By leaving every thing clamped in the arm will want to stay square. The insulators an shoes stop it moving to much if it move as all. Once your insulators are plumb in the end everything is back where ya started.....

Nice drawing. :)

[aviewfrom]

Nice drawing. :)

Thanks :)... I forgot to draw in the wallabies though.

[BigClive]

You could probably have used the tirfor to both support the good pole and extract the old pole in one action. I've attached a picture to show how. What do you reckon?

[bren guzzi]

I will try your method on the next one clive...

If it works we shall name it ... "The CLIVE caber toss method".

Keep taking the tablets "brother". ;)

[BigClive]

Just make sure you video it. :rolleyes:

[birdog37]

Drop outside phase down off rotten pole,attach middle phase to existing old good pole,cut old pole off a little above ground line with digger attached.After cutting rotten pole off set old pole to side enough to set new pole to best accomodate you for arm xfer. The pole should balance itself.Drive a ground rod in center of rotten pole with hilty gun, pull butt with bulldog grip.Set new pole in same hole reamed out to proper depth.Tie old pole to the one you just set.Begin transfer from old pole to new one.Utilizing your chain saw to accomodate the xfer.

[Special ED]

Drop outside phase on the side your changing out the pole. Take a short web strap around the arm and to a 1.5 ton hoist right above the x braces. Tighten it up a little. On pin the arm on the bad pole yank it out and plant a new one. Pretty easy. We do 4 a day and you gotta drag the trucks in with dozers.

If its double arms it's easy too. Take a strap around each arm and up to the static with ton and a half hoists. Leave enough room for the old pole to be slid into the middle of the structure. Tighten the hoists un pin the arm. Take you a car jack (be sure to tie it to an arm) and jack the arms apart to give you some room. Now it's time to grab the pole with the digger and cut it off about ground level. Slide it in towards the middle of the structure and set it on an outrigger pad. Clean out the hole and set the new pole. Now stab your arms transfer the static and pull up the dropped out phase.

Piece of cake.

[bren guzzi]

We've got to use the company "aproved" method that I showed earlier....

BUT if I can try another way ............ I think big Clives Scotish caber tossing method is favorite. :). ;) ;)

[Pootnaigle]

Ummmmmm as the title implies there are a number of ways to do this. I beleve all of em mentioned thus far would work just fine.( ummmmm maybe not clives) but it is interesting to see how it would be done by different folks.I spect before itz over n dun with there will be several more workable methods.
