Mechanical jumpers

Got another question for you power folks.............which do you prefer? Duckbill hot line clamps on mechanical jumpers or those big orange screw on heads on your jumpers?

I just got word yesterday that we can no longer have any mechanicals with the duckbills or standard hot line clamps on them. The only approved jumper clamps that we can now have are the big orange screw ons. What is funny is that the utility here made it a point that they do not want any jumpers with the big orange screw on heads to be left overnight on any part of their system. That came after a circuit burned to the ground over the weekend a while back. My opinion was that maybe that head was not tightened down good enough anyway, but I still think that with hot line clamps, there is no mistaking whether you have that baby tight or not.

Most of us know the tricks to tightening those screw ons, but there are still a lot of new guys that don't. So now, if we are jumpering out a phase, before we can leave for the evening, we will have to put up jumpers made of the same size wire and more than likely, we will have to install temp. insulators also.

My time is limited here at this place, which I am glad of, but I am still curious on what you guys prefer out there.

Does that mean you guys are throwing out all the duckbill jumpers? :smilie_daumenpos[1]:

We use the big orange heads when we rubber glove. But if we are hotsticking we use the hot line clamp style mechanicals (not home made ones). So for me it depends on what work method we are using.

Not sure what you mean by duckbill type. We've used anything from poly wire with hotline clamps to the big 4/0 orange mamas. I trust the big bad orange mamas more, just dont like taking off hotline clamps with my hands like I was taught. :smilie_daumenpos[1]:

I agree with what you said about the line burning down, I doubt the wire was brushed clean nor were the heads tightend down enough. You could screw them tight and hit them a few times and be able to get 2-3 more turns on it and tighten it even more.

They are going to wear your ass out making up jumpers everyday of the same size wire. Mechs can be left online safely, we made sure the heads were on tight and even kept the line off the pole even though its protected.

This 11000.JPG vs. this 10375.JPG or this 10476.JPG.

The problem with the screw ons is that they don't get tightened down as good as they should be. Had an instance where a high wind picked up over a weekend and the moving of the conductors loosened the clamp even more and burned the wire down. Plus, I like the option of being able to stick the duckbill in a shotgun if there is any doubt in my mind about a particular phase. I know to hit on the screw ons and tap them with a hammer, I even put my channel locks on them to get that extra measure of security, but the problem of them working loose is still there. They are fine for jumpering something for a short time and then putting a permanent jumper in place before you leave the pole, but I don't trust them overnight......and especially not over a weekend. So, I am still trying to figure out why we have to get rid of all our duckbills. And your right, that just created a whole lot more work for us and we are already getting the hammer lowered on us for more production.

(1) Tapping the head of a Insulated jumper with a set of Klines while tightening will prevent the jumperfrom lossening in the wind. Also tieing up slack will prevent wind from swinging the jumper.

(2) Houston Light and Power was one of the first company's that started rubber gloving over 4,160 volts. I have been rubber gloving above 72,00 since 1968.

One of the first rules about jumpers is NEVER PICK UP OR DROP a LOAD by hand. They make a Hot MAC that has a load break built in. Apply it by hand, back off and trigger it with a stick. Jumpering out lines by hand is a major cause of Fatal Burns. Work Safe.

Personally, I use the duckbill for almost everything, and have left them temporary for over a week sometimes and never had them loosen up.

Very rarely do we use the screwon type, but I can see where they will loosen easy especially when being put on by a gloved hand, and would be hesitant putting channellocks on them.

I use the duckbill mechanical for everything from mechanical jumpers to personal grounds, and like them.

Everyone probably doesnt agree with that but ot works for me.

USE USE THE BIG ORANGE HEAD --HANDS ON--SCREW TYPE..........................THERE IS A TOOL ...........MADE BY A LINEMAN---IN TEXAS, IF I REMEMBER RIGHT--------MADE FOR TIGHTENING THESE, WITHOUT DAMAGE TO THE HEAD.................WE USE CHANNEL LOCKS AND HAVE LEFT THEM ON FOR WEEKS, BUT ONLY BECAUSE WEATHER PREVENTED US FROM COMING BACK TO FINISH UP......................TRIED TO GET THE COMPANY TO BUY THE TOOLS, CAUSE IT DOES NOT DAMAGE THE HEADS OF THE MECH............BUT THE COMPANY SAID NO,,CAUSE THE GUY DIDN'T HAVE A MILLION DOLLAR BOND ON HIS COMPANY :laugh: .THEY PREFER TO REPLACE THE MECH OR HEADS-----MORE MONEY---THAN BUY A $15 TOOL TO SAVE MONEY :shakin[1]:

WE DON'T STICK ANYTHING ON DISTRIBUTION................ALL HANDS ON...........ONLY STICK THE TRANSMISSION VOLTAGES AND I DON'T THINK THEY /WE DO MUCH OF IT ANYMORE.......................

Livewire, what do y'all do to tighten them and keep them tightened?

Batts, I agree with not using them for dropping or picking up load. But, I have picked up load with them (Duckbills) before using a shotgun. Was an emergency situation and no where at all to mount a temp switch. 3 Crappy ass CSP's would not open at the secondary switches. Got lucky and no drama came from that one. Would not have been able to do that with the big orange screw ons.

We always just had them hand tight (and used the slap technique a few times) and they always held for us. Never had a problem. Also rolled up the access and tied it to a standoff pin to try and keep pressure off the orange mechs and to try and keep them from tracking in case of a hole. Used the duckbills on grounds and that was it.

We worked an Ice Storm in Georgia around 2000, and we had this 'so called' lineman with us that decided we were going to pick up a whole community (500 or more houses give or take) and he wanted us to pick up the load with a big orange mama. Told him to go to hell and he could do it himself. He eventually done it, I walked off and wasnt going to be involved in it. That was the last time we worked with him, but he is now a foreman in those yellow trucks. It's a shame somebody like that runs a crew.....

What did you expect? The things that I have seen in 4 months! Heard of a crew that opened a 100kva 3 pot bank under load. Sustained some good burns when everything went phase to phase. I asked where the loadbuster was or why no one dropped load from the bank beforehand. I don't even think anyone got voltage and rotation before opening the bank.

SOME PEOPLE................ARE JUST LUCKY AND STUPID :confused-smiley-013[1]:

I GUESS GOD LOOKS OUT FOR DUMB LINEMAN TOO :Voskl1[1]:

I HAVE NEVER PICKED UP LOAD WITH A MECH.........EXCEPT THE LOAD-PICK-UP ONE I HAVE ON MY TRUCK :rolleyes:

TEST IT OPEN....TRIP IT............OPEN IT BACK UP...TEST IT AGAIN.............PUT IT ON-LINE...THEN TWIST THE HANDLE.................THIS ONE IS CLOSED BY TWISTING THE HANDLE, WHICH IS PRETTY LONG.......NO SHOTGUN OR STICK NEEDED...............

We used the orange insulated duckbills type jumper with the shot gun. we trie the new type of duckbills all aluminium. The scew on them if you tightening them realy good and trie to remouve it, you will have a suprise because the tread will jam and you won't be able to remouve it. We replace them with the old brass type

I must have missed this post TLW

I tighten mine the way Crip described, slap'em side to side and tighten some more, repeat.

Jos Lapointe, we have grounding chains just as you described with the AL threads. Your right if you over tighten them it'll jam the threads and it's a real SOB to remove.

Any of you guys use the temporary cutouts and mechs in combination?

Never have seen the duckbills with aluminum threads and from the way it sounds, glad I haven't!

Livewire, I have used the temp. loadbreaks that you hang on the conductor and used a mechanical from the switch to the other side of a temp floating dead-end to kill out a section of a neighborhood before. Wanna have fun? Send your grunt with an extendo to close them in! :surrender[1]:

I use the A B chance in line switch with one short and one long orange insulated jumper work realy good to separate line circuit with the load boster we have 12 of them to work on tree phase line

It make easy to separate a bad conner or replace a pole that is not safe to work on

be safe

Hello texas lineworker

Look back at you reply on the 22 dec 2006. the duckbill that we use is the one on the right but the tread is brass. The rating of the jumper is the wire gauge inside of it

Hey bro, yes, that one with the spring loaded duckbill is the kind that we have been using. But, every one of them is coming off the trucks real soon.

JOS,

TLW IS HEADED FOR TULSA. OKLA, ON THE ICE STORM................................. BUT TO ANSWER YOUR QUESTION.............I BELIEVE JOHN HAD TOLD ME THAT CPS--CITY PUBLIC SERVICE IN SAN ANTONIO , WHOSE OUTFIT TLW IS CONTRACTED TO, HAD TOLD THEM THAT THE MECHS WERE NOT TO BE USED ON THEIR SYSTEM....................SEEMS A LINE WAS MECHED OUT, TEMPORARY OVERNIGHT, AND THE LINE BURNED DOWN..............AT THE MECH............CAUSING A LARGE OUTAGE......................

I MAY BE WRONG, BUT TLW WILL NOT BE ON THE BOARDS UNTIL RETURNS FROM THE STORM.........AND DIDN'T WANT YOU TO THINK HE WAS IGNORING YOU :Voskl1[1]:
