beal regate 10mm

[PRUNER 1]

is beal regate 10mm actually strong enough to be using as a bridge on the bf, attached with fishermans? swl etc

 

[John Paul Sanborn]

I looked it up on the internet and it is rated for 1700# tensil. wich would make it 3400# as a prussik.

Not ANSI complient.

I don't know if i would want 10mm either. Seems a little bulky.

 

[PRUNER 1]

does this mean its strong enough though?

 

[John Paul Sanborn]

Doubled it has a 3400# tensil.

That means that it could not be manrated in the US, using ANSI Z133 standards.

The new Z also requires that the Manufacturer approves the rope for tree cimbing useage.

 

[PRUNER 1]

what would be the appropriate stuff to use then that i can get my hands on over here in blighty? and what is the best way to attach without splicing?

 

[lync]

simple solution

How about a piece of climbing line? Or perhaps a split tail, you could girth hitch one side and double fishermans the other side?
No special ropes need.

Guys, he's talking about using this as the bridge on his saddle, not as his friction hitch. So the "doubled strength" is of unimportance.

And it's strength is listed in kilograms. That'd equal about 3,700lbs. Still not really strong enough

I woulda thought that rope to be much stronger than only 3700lbs.

Pruner, are there any sail supply stores near you? I bet we could find you something good from there!

ive heard of using climbing line threaded through the small rings and fisherman'ed(?) on the ends so it cant pull through, but sounds a bit hit and miss to me or is this sound?

 

[PRUNER 1]

there aint no sails places as ime inland but we do have rock climbing shops with loads of different statics

 

[TreeJunkie]

Well you could use something as small as say 5/16th ultra tech, either tied w/ fisherman's to each ring. The breaking strength i believe to be around 7,800lbs. Or, you could have it spliced to each ring if you can find someone to do it. 11mm kernmantle tied up the same way would also do a nice job. This isn't how mine is personally modified but, then again my saddle get's d/q at comps.. not that it's not strong enough or safe. By the way you should probobally consult w/ Komet in regard to this before hand, don't take any suggestions unless you speak w/ them first. These are only things i've seen in the past, not that i am condoning them as being safe...

Which is why i said here in the US.

heres another look

Pruner1,

Have a look at the SWL of Beal Regate 170kg (10:1) configure it is a bridge for your butterfly, load it in the middle and do the calcs with a deflection of say 30 degrees, take a look at the applied loads. Not something i would want to use!

Plenty of options to create a bridge if you want to, home made, ART Butt Set, Petzl Swivel, Cambium Saver ring .. just a few.

As far as Bacou-Dalloz (manufacturer of the butterfly) are concerned ....

The strap should be replaced with a rope, and not a sewn strap as BD cannot identify thread strength and procedure.

The rope diameter should be equal or above 11mm

The rope should have a breaking strength of equal or above 22kn

The rope shoudl be attatched to the rings by an anchoring knot (double fishermans knot)

The total length (from ring to ring) of the bridge should be 400mm max.

If the replacement bridge is configured so that you pass the rope through the ring and tie a monkeys fist to prevent the rope pulling back through the ring the recommended diameter is a minimum 12.5mm / 16 strand rope

What are you using at the moment?

Also remember that your set up will have to undergo the scrutiny of an independant LOLER (UK Legislation) inspection, six monthly in the case of PPE.

ive stopped using the beal on my bridge now and this is what ive come up with, only used it once so still unsure of it.

 

[PRUNER 1]

heres a close up

 

[ccooperabbs]

Looks good, what's the line XTC "Spearmint" 12mm? And the ring? An old buckingham cambium saver or something else? Pretty much he same as mine on my evolution, i Have the ART Butt Set, would maybe want to get some loading into the system and keep an eye on the length of those tails, ideally 12mm rope, 6mm tails min. Would get you through a LOLER check with me.

as far as ime aware its spearmint 13mm, my old climbing line, now the end of my short street tree line, another lump lost, anyway i was going to stick arborgold in just cos its pretty!! anyway, the ring is from a buckingham cs and ile keep an eye on the tails. them knots are absolutely solid, aint comin apart so will have to cut them off!

Chris, do thay have that on the internet or other on paper?

I've heard the oposet that they recomend 22kn sewn strap as replacement.

Competetors may need the documentation for ITCC chapter events.

 

[TreeJunkie]

Why would 22kn, be sufficient, in every thing else we use for life support it has to be 5,000, 22, is falling short of this.... I have a sewn strap but have ditched the aluminum rings, it's safe as could be...
