Spliced eye on lowering line.

[Mesterh]

They do come with sliced eyes if that what you ask for! They are all sold by the meter aren't they? So you order the length you want and ask for eyes if you want.

 

I've never bothered with them but can see the advantages.

 

Ive just never seen them advertised with either spliced eyes or the option to get them spliced unlike climbing lines. I just thought it was something that wouldnt be done rather than couldnt.

 

I do need to get a new lowering line since my old Yale one is looking at bit past its best, well actually some bits are looking a bit square rather than round due to heat damage!

 

Think I will deffo be ordering one with an eye now though.

is it not to do with working load limits???

 

anyway, teufelberger are now offering a spliced eye on the lowering rope in their new catalogue.

A splice is way way stronger than a standard bowline. A splice has generally upwards of 90% strength of the rope. a bowline generally weakens the rope by 40%. I.e a breaking strain of a 1000kgs with a splice may be reduced to 900kgs whereas a bowline would drop it to around 600kgs. these are rough numbers etc. go look em up if you want greater accuracy.

 

a thinble in the eye will improve the strength of the splice over a 'soft eye' but i don't know rough numbers for this.

 

get your new rope send it to me and i'll put a tasty splice in it if you want.

 

oh and you shouldn't be loading karabiners that way. it aint good for them.

Ive got about 5 ropes in need of splicing. What's your address haha

We use a few 3-strand ropes for our basic rigging operations. They are cheaper if they are burnt or need to be cut, etc. They are spliced (without a hard thimble) at both ends. The 3 strand also is incredibly easy to splice and therefore doesn't require it to be special ordered with a splice.

A splice in any rope for rigging purposes also keeps the rope from "milking" (the core sliding up the cover).

 

The use of a Carabiner in Rigging operations should be heavily monitored. Equipment that has been used in rigging operations should be kept only for use in rigging. Once used in rigging, never again use that item in a life support operation. Steel Carabiners are designated for Rigging and are much stronger (40-50 kn vs. 22-28 kn) and heavier than typical life support Carabiners.

A Running Bowline is fine for rigging and I use them all the time. However, breaking strength of a knot (40-60% strength) vs. breaking strength of a splice (90-98% Strength) must be considered in larger/heavier wood extrication operations. Such operations necessitate the use of a steel Carabiner.

 

ok... poor ole decomposing horse has been flogged to a pulp...

Getting prepared to be laughed at here but why arent lowering ropes spliced with an eye?

 

I have my suspicions but was wondering what the real reason is.

 

Would make things a lot easier ,well would for me and my dinosaur lowering ways.

 

They are, or at least can be, it's up to the retailer many of whom are just salesmen and cannot splice rope or don't because of some unfounded fears, my local retailer even told me once that you can't splice double braid rope!

 

Anyway, learn to splice yourself if you can, Nod from Treeworker provides courses or you could just teach yourself, once you get your head around it it's pretty simple, especially lowering lines.

Cheers for the info fellas and the offer of splicing it. At the rate I buy kit I should have a new one by 2015

 

 

I do use a big steel krab I think its rated at about 40kn but could be more as its a nasty big bugger that you dont want smacking you in the gob while lashing it around timber:crying:

 

I never usually rig big stuff off anyway tbh, well nothing even remotely like some of the stuff I see in the vids on here:thumbup:

 

Think I will deffo have a bash at the splicing. Theres were a few nice vids that I think Mick posted up from youtube but they have been taken down now!

 

Anyone got some links to a few good uns?

Mesterh: earlier I think you mentioned that you only do natural crotch rigging? What do you do about pruning trees to be retained or trees with tpos?

[Mesterh]

Well most of the rigging I do is mainly on take downs.

 

Even so I would still use natural crotch rigging regardless, I'm a rebel like that, I dont even own a cambium saver.

 

Cue the slagging off.

Get right off arbtalk now. Your taxi is waiting for you. don't you even care that you maybe hurting the poor tree giving it friction burns of the highest order. I hope the next tree you do gets a branch with a bit of tension on it and slaps you square in the goolies. That'll teach you.
