How to make roll cables through corners and all around ? Answered

Well I decided to join cause I was looking for a solution of a problem I have at my job. I work in a datacenter, and frequently I have to pull delicate cables, which have to run through many corners, sometimes they got stuck between sharp metal pieces on top of the racks, or even the doors. Not only that, but also the times that get to pull them from one place to the other (sometimes cables of 60 or 80 meters. You have to be also carefull on not pulling so much. So I was thinking in to invent something to put in many places as auxiliars that let run the cable in every corner. Many Ideas but I am not in use very frequently with the inventive that your experience have. But I think I discovered what I like most in life. INVENT THINGS.!!!!

This is actually the skill I took in my first trip through college - network cabling/info tech :D Pulling wires can be a pain, you always want your plenum or rack feeding wires over rounded corners or through electrical conduit with pull-boxes every few meters to keep the pull tension low. There are dielectric lubes available for cabling to aide in pulling long lengths through tubes. If you can't run conduit, then plenum or troughs designed for cable shouldn't have much for sharp edges. If you want to invent something, then make little guards for around corners to make pulling easier.

Well I have to admit that this is getting very interesting. Let's try to interchange all ideas we have. This adds a lot to the whole problem

So you guys do you think we can invent something with all the coments and graphics we did here. Or at least bring some graphic Ideas to try to invent something. ???

Well guys and girls of course... As you can see I have to pull this cables. The cable comes in a roll which has to be set on the floor, one end very far away through the corridors and with the other end in your hand needs to be pulled from one rack to another. In the way you will find corners, sometimes with the abitilty to get the cable stuck or even cut it, when you have to pull hard being far in the path. :) The idea is to invent a kind of device or something to attach it to corners, but should be also for all kind of corners or metal places as you can see on the pictures that shows through where the cables have to go through. Sometimes also we need to pull a lot of utp cables, So what you think brotherhood of the mind ?!?!!?

The idea is that I can carry 5 or 6 devices on my pants and puting them very easy and then later once the cable is hanged and it's place easy to take it out.

This has been a huge issue since the day cables were able to be pulled - either greased plenum or conduit, or literally only pulling 'the entire length' past each bend manually was the way to go. I'm sure there's some sort of pulley that you could outfit whose axle was detachable from the 'grappling hook' mount to allow you to make the corners easier. I can't remember the name of the clip I'm referring to - you use them in sailing a lot to hold the mast stays on - a pin with a clip that keeps it in, but easily hinges off to be removed.

Really though there's no substitute for pulling short distances at a time, with the full length required to get from a-to-b.

When you have to pull cable 100 meters, you pull the full 100m length of cable, but you only pull it 1-10 meters at a time. Start, feed the wire (to someone) who pulls the correct length, as far as they can safely - usually to the next corner. once it's all pulled through, you move forward and pull the next section. It's a lot more work, but it makes sure the cable arrives safely.

the problem is that you make this alone. there is no problem pulling little by little. It is what we do, the thing why I need this devices is not mainly to protect the cable, but to make the process faster.

Hire a minimum wage kid who is going to college for 'network' IT. Good help can be hard to find, but if you get the ones that really want the job when they graduate they'll work hard to get a good reference.

Well look the device should be adaptable for a corner in rack aswell when you use agains one of the wall of the mini metal corridors in the top part

You could do exactly that - have an 'inside corner' and 'outside corner' version, either tethered to a hook, or attached to a clamp would do.

minimum bend radius in optical cable is a farse. You can tie that shizz in a knot (tightly), or hit it with a hammer with no ill effects- it's when something sharp penetrates the outer casing and nicks the glass it's game over (we did attentuation tests in network cabling classes) that bend radius is just for pulling - because pulling around applies a lot more force. VERY good suggestion with the half cut tube.

yes seandogue they have to be removable, and little to carry arround. Cause this task is done many times during the week let's say.

They don't have very good plenum - so its ripping the casings when they drag it around corners. He wants to be able to pull a longer length with a 'something' (I suggested pulley) at each corner...then remove the pulleys later.

I'm not sure I fully understand the problem, but I'd imagine that parts of the connectors on the end of the cable would hook and catch on sharp edges. So some kind of removable sleeve is needed to stop (for example) the little hook on the ethernet connector (RJ45) from catching on things?

Yes, that's happens too, but when we have to take out the cables pulling back through 20 or 40 other cables in the metal little corridors from the top

when you use fiber optic cable, you use with terminators too
