Hilti Capping

[Tim Watts]

A couple of people have recently asked 'what is capping'. Being no expert at all on this i thought i'd post this video.

NOTE: Just to be clear, BCA Insurance DOES NOT cover this activity!

Q:
Is the use of Hilti caps covered?

A:
No. While it is an open question as to whether the technique is actually legal or not, the fact remains that the experience to date indicates that the technique is simply not safe enough to be considered as an acceptable risk in the context of caving in general. It may be that individuals have identified equipment and procedures which leave them satisfied that the technique is safe enough for their own purposes, but this is still a long way from being able to accept the risk of a claim from an untrained and inexperienced individual. Over time, we may be able to define procedures, training and equipment which allow the use of Hilti caps to be seen as low enough risk that they can be included in the PL scheme, but this point has not yet been reached and therefore we must regretfully conclude that the scheme cannot cover this activity whoever undertakes it.

Having never done this, I am assuimng that should one fail to do the job, You can repeat in the same hole with 2 caps?

[mike leahy]

best practice is to drill another hole alongside un-expoded cap and repeat. if you put another cap in the same hole you are in danger of the second cap squashing against the first cap as it is a softer material than the rock. one hole one cap other wise you end up like that fool , most capping is done in confined places as well as close proximity to the object/rock. if it make a dull thud you know it's done the job

He may as well have taken a bazooka to it .

Still an informative clip, cheers Tim

What's with the Colour coding of the Hilti caps? Graded according to how powerful they are? If so, what ones would you get? Are some too powerful for use in a confined space?

if i remember correctly the weakest ones are yellow then red then black, the yellow's are not really up for the job for us . you must remember that they are't desighed for this lark.

No link in your post, but a search reveals a most interesting product.

I presume it's for use where surroundings are too unstable to use stuff that goes Boom?

Having spent some of my Teenage years in the US, I'll agree wholehertedly with that. Seeing a full stick of TNT go up is something else. I wasn't so keen on the Dirt-shower that followed shortly afterwards though!

heres a slightly more realistic - in action - version.

Major risks that i am aware of....

Firing the rod back at you like a bullet
fragments coming back up the hole at you (fragments of the metal cap that is) hence the heavy piece of matting - some claim thick rubber off a conveyor or similar is a must along with a large diameter washer on the striker rod too.

I've a pot of 100 'reds' if anyone wants to play with them.

What is interesting that i've heard the the shape of the striker rod is important in a way i'd never before realized.
