How do you secure your Port A Wrap?

[Scott Farmborough]

I;ve never thought of doing that.....Had a Beech to do and my whoopie wasn't long enough......Grrrrr. Ended up using the tree strop.

 

I shall find a hench rachet strap and give that a go. I use a Buckingham Porty.....how is your porty attached to the rachet strap?

I just use a D shackle behind the strap, the great thing about the ratchet strap is their is zero movement (i find it a pain when the port a wrap flies in the air under load)

with the rachet it stays in a fixed position.

Bodean,

your picture is neither a cow hitch, or a timber hitch. Where did you learn that knot?

surley though a properly pre-tentioned rigging line should not fly up anyway?

When snatching as you push the piece over the line always goes slack, there are ways to minimise this, anyway i've seen groundies lose control of pieces as the capstan has thrown a wrap when going taught, it is rare but can happen especially with the larger ISC capstan.

You can always use a mechanical advantage system to pretension the lowering rope, or just get a couple of big groundies to hang off it!

 

This is the one application where the Hobbs really rocks. Much better than the grcs or indeed any other lowering device out there.

I have never understood how this can happen especially if you use a krab to secure the line. Operator error?

Of course its operator error not knowing the device needed a krab to secure the rope and the slack throwing the rope, lesson learned. How many people here know that you should secure the line to the larger ISC capstan with a krab? It doesn't exactly come with instructions.

I can see this happening with the isc portawrap I've got, theres nowhere to secure the rope with a krab.

A bit off topic i know but with a grcs you can snatch on the sailing bollard, with this you take advantage of the one way drum as the climber snatch's a piece you can immediatly remove all slack then let it run for some real smooth rigging.

Not sure about the hobbs as i've only used a grcs.

[Peter]

I always find the lowering part of the exercise a bit jerky on the winch drum with the grcs.

The ratcheting drum of the Hobbs is a far superior animal for this particular job, you can whip all the slack out as the piece goes over, just as you say, but letting the piece run and bringing it to a controlled stop is much much easier.
