How to protect hydraulic hoses ?
« on: November 05, 2015, 08:54:30 PM »
This night be a question for all forwarder or crane operator or those who have a forwarding trailer.
I developed a problem with my Patu loader ( I think they're called Kesla now ).  When the stick is all the way in, the hoses get pinned between the linkage and the nut which holds the shaft in place . On the other side it's not so bad, but there is four hoses. I tried to reroute them and zip tie them together, but it only works  when it's all the way folded back but not when the stick is all the way out, because  then they get pinned from the top of the stick. When I reorganize them the other way it's fine when the boom is all the way out , but get pinned again when it's all the way in. 
Little hard to explain, but hope everybody can follow.  The hoses are protected with some heavy duty water hose, but I don't see a high live expectation in them with having them constantly pinched.  Some of the steel lines on top of the boom are bent and I am thinking this is not all the way it supposed to be.
Any ideas or suggestions ?

 

 
 

 
 
Make sure you know how to fall properly when you fall and as to not hurt anyone around you.
Also remember, it's not the fall what hurts, its the sudden stop. !!

Could you rig up some sort of retraction system, like an tool balancer spool, to pull the hoses out of the way when needed?
Can the hoses run to the outside of the hinge, or did you already try that?

If you can't find a way to move them, get some or 1" pex pipe and cut a lengthwise slit and work it on to the hose and tape it there. The pex is fairly hard and slippery so it will either slide out of the pinch situation or do a better job of protecting the hose.

I use split pex to replace the metal pads at places the hoses are clamped on my backhoe and it's worked well.

Along the same line as sprucebunny mentions, there are cable and hose spiral wraps that could be used and have seen such around hyd. hoses on big machines.

A link to what I refer to here.

a pic from a bit further away would help. hose on the rite in first pic needs to be outside of the steel bracket. real hose wrap would help

From what i can tell from the pic the hoses are not routed right .they should be on the outside but it is hard to tell from the picture

Thanks for the replies. Thought maybe they should run along the outside, but for that the steel lines should be on a 45 angle at the end.  Also there will be a bigger loop hanging down on each side and it's probably easier to catch on to a limb or something.  It actually makes more sense to have them inside , but I need to find a way first, or find out how it originally was routed.  Can't find a tag on the loader ( just says   PATU  )
Will take some more pictures tomorrow.

The spiral wire wraps I've found to be no good as they wear into the hose with time.  Is there any possibiltity that you can run a fixed metal conduit through there where it can't pinch, and have the excess hose that will move in a different location that won't pinch?  Maybe have to have excess hose on either side of the metal conduit so that it can move.  It's hard to tell what exactly you have going on from those pictures.

  It looks to me like the hoses are in the wrong spot  :)
  I get much longer hose life with the spiral wire hose wrap compared to the plastic stuff on my Fabtek head.  The wire protects better against crushing than the plastic stuff.  When a hose fails that was wrapped in wire it was from too many flexes.  Crush failures are common with the plastic but it's way better than nothing  8) 8) 8)

 Google "Baileys Hydraulic". They sell the pigtail wrap, I've gone thru about 12 boxes of it so far. Helps alot, but like Corley said you might have hoses run the wrong way, or maybe a better way to run them. My forwarder is a hose monster, always chasing hoses.

Took some more pictures today. Hope that gives you guys a better idea what I am talking about.
Maybe I didn't had my first post worded right. I wasn't looking for some material or spiral wrap to protect the hoses, more of a way or ideas how to prevent them from getting pinched.   My apology.
Still think it was original to run them on top of the boom right to the end. There is about 1 1/2 " clearance between the main boom and the top of the stick , when it's all the way out. I thought if I find a way to clamp them down neatly side by side, instead having them stacked on top of each other.
Would that be a idea ?  Some short bolts or threaded rods welded in the right position and have some flat stock bent  to hold them down ?

That hose run is probably supposed to be clamped together side to side, so that they all bend as one up and over the center of the hinge, rather than flopping to each side.
Like this, (but not welded to the boom): http://www.surpluscenter.com/Hydraulics/Hydraulic-Hose-and-Hose-Assemblies/Hose-Clamps/1-2-IN-TWO-WIRE-DUAL-HYDRAULIC-HOSE-CLAMP-9-A3-213-D.axd
The steel lines in the last set of photos probably need to be skootched  back a few inches for fitting clearance.

I know what you're saying NRE . I thought about that too.  But if it was like that when it was new, there should be at least some  45 's or 90  elbows at the end of the steel lines. But that doesn't mean it can't be done that way.
I haven't found a place yet up my way , where I can get those clamps, but I have seen them before.  That might be a option too.

^If you aren't the original owner, it's possible a previous replaced expensive angle-ended hoses with cheaper generic straight?
Thus the oddball routing?

I got those clamps from SC for the boom on my forwarder.  They're not very durable  ;) :)

Brought those mounting bracket home the other day from my hydraulic shop.
 

 

Turned out they were too small in diameter. So I got a little pithed at my self for not taking measurement. I really thought,they would work.
But now I didn't wanna make another trip to town and spend another $ 35,  plus  there had to be a bit of a punishment. ;D

So this it what I came up with.
 

  

Seems to work for now, but in the long run thinking about running all hoses over top.
 

 

Thank you for all the replies.

     I'm not too big of a fan of the brackets in the first pic.  That's the style the Ponsse machines use, they would be great but the threaded part in the backing plate is spot welded in. They have a tendency to pop out when you try to torque them down.

I've found that on a lot of new stuff that you buy you have to get out the welder and finish the job before you put it to use.
