Need advice for long pulls

[masterinbama]

I've created a diagram to assist:

Either it's an easy pull or Mr. Pull is a show off, he's only using his left hand.

If you are using PVC for the runs, you may want to change to rigid for the 90s where they stub up, I have had pull strings and rope cut through the inside of 90s during longer pulls. Use lots of lube, pull a swab or rag back and forthe to pre-lube the conduit. If you dont already have them, get yourself a pair of hands free radios.

Mr. Pull isn't showing off by just using his left hand.... he's pulling the slack of the rope up. Notice the head next to Mr. Push? The real work is about to begin.

Not shown is the drawing is Mr. Lube, and the Grunt quadruplets. It would be easier to pull straight up instead of the 40? angle, however.


Apparently, Mr. Phasetape called in sick.











I won't mention the apparent 300.18 violation.

With big reels, I always pull from the bottom, your not pulling the weight of the remaining wire, (odd when you really start to think about that, huh!)

Walkie talkie's or open phone line or the cherp masters (nextel's)!
All should be relocated to ones collar, esp. the motorized tugger man!

I like to use a roller on the inlet side, on a chain ususally placed about 1.5 to twice the distance up and away from the size of the roller itself, this will buffer the slap of the rope/toggler, and not whip someone's arms around.

If your can: use a chain for the pipe thats through the reel as well, if you have to use jack stands keep one stand leg pointed at the pull and keep the reel as low as possible if on a jack stand. The rise up to the roller again will buffer the heave-ho of the puller. Your "feeder" should be between about 9' between the roller(feed)and the reel. Put it this way if using any chain increase the distances so that no breakage puts any one in peril!

With the use of a chinesse gripper, be sure to pull some circuit strains back through the metal weaves... do not tape the end of the grip, this will cause the grip to loosen from the stop and start of a pull... and don't use at all (OK, JMO)

Everybody be sure to swing their arms and flex and stretch there upper body, before the Orders are given to man-up on this ! ! !

It is fun to experiment with new programs.


But....

You need to feed those guys...otherwise they will not have the strength for long pulls. :grin:

Probably the most important comment yet was pull and push straight into the pipe (called the critical angle).

If working alone, I use a remote wireless switch to start & stop a winch and just guide the wire in straight.

Wow I completely spaced the lengths. Sorry for that. The #2 is about 380' and the 1/0 is about 550'.

i'm assumiing you don't have tugging stuff.....

buy yourself a spool of mule tape. it comes in different strengths.
buy a spool of 3000# test. you can get it cheaper on ebay.

buy a pail of pull string, and a mouse for the size pipe you have in the ground.
use a strong shop vacuum to suck the mouse in, and get a string in the pipe.

use that string to pull in the mule tape. the mule tape will not cut plastic pipe,
is very low friction, and can be used to pull directly. 3,000# test is enough.
it has every foot marked, so you can get an accurate wire measurement.
it is disposable, and a spool of the stuff is wonderful to have around.

did i mention i like mule tape?

get the mule tape in, get your measurement, order your wire cut, on separate
spools.

get a stick of 2" rigid. use it for an axle. put all the spools on the rigid, with
the wire coming off the top. i'm assuming this is an industrial situation, so
borrow a forklift, set the forks wide enough for two or three of the spools,
and put the other two spools outside of the forks. make sure there are no
tails of wire sticking out the sides of the spools, cut them off flush. place a
3" coupling in between each spool, and forks as well, to keep them from chafing.
i also use couplings on the outside of the reels, with kant-twist
clamps, to keep the outside spools from walking, otherwise the pipe will flex
and they'll walk off the pipe.

use a pair of c clamps on the forks, to capture the axle, so it doesn't walk.

pick this up, and position it so the wire will feed off the tops of the reels,
down into the pipe.

if your supplier uses webco reels, get it on webco's. put in the axle the
same, and get it up in the air. webco reels have a locking pin that holds
all the spools together, so the wire can be wound on at the supply house.
make sure you pull the pin out BEFORE you start the pull. i had a crew working
for me once that didn't, and the 4/0 turned the 500's faster, and the whole
thing got balled up.... don't even ask how long it took to fix, with 2,000' of
500 mcm at stake.

make up the pulling head. if you don't have hardware, like socks or cable
grips, you can make up a basket from tie wire, or skin back the wire for
2', take two strands from each side of each wire, cut the rest off, and
make up a pulling head.. use a swivel. buy one if you have to, or pm
me, and i'll lend you one... i have half a dozen.

there is wire insulation available that does not require soap. use it.
it's wonderful. use it. dump a quart of soap down the pipe anyway.

get a maxis 3000# tugger. rent it, whatever. set the tugger up to pull
out enough cable to make up without re rigging to pull more.

wires up in the air, soaps in the pipe, spacers between spools. take up the
slack, get the head in the pipe, and pull it. it should feed by itself. if you rig
it right.

it should take longer to set up the pull than to pull it.

working by myself, i've pulled 4 500 mcm copper and a ground 300', thru 4
90's, without help, using the above setup. took two hours to set up, and
half an hour to pull.

if you've got any questions, pm me.....
have fun.

They're stub-ups for future pole lights

Look at the power cable installation guide here:

You can order a printed version that doesn't seem to have some of the font issues seen in the web version.

LOL! That is a cool graphic!

Pullbox/voltage drops

How come no one mentions these Items.

U can use NJTP shows their requirements. They have JB set at not to exceed increments.
