Hanging Rock Swing

Ever since I saw this swing, I have been so ridiculously keen it's not funny.

There are a few of us down in Gong town who are pretty keen to get out there and lob into space, however none of us has the experience of setting up something like this.

Is there anyone out there who a) has set up the jump before and b) would like to come out and do it again with us? You will be rewarded for your efforts with beer.

Would be sweet if I could hear from someone. Pm me or reply here if you're keen!

Cheers!

Just a side note - you will be rewarded for your efforts with beer after a successful completion of the jump.

Haven't done it myself, but went out there to have a look a while ago for slacklining motivation.
Question for anyone out there qualified to answer: Is the anchor on the Hanging rock really the bar fridge sized block nestled atop of some shale at the prow??? Maybe there are bolts over on the Grose side. Or do you merrily lash the bloc to Hanging Rock itself???

Whilst on the topic, I might be completely retarded about all things bridge swing, but I could not work out the Knapsack bridge anchor config either. the bolts are on the upstream side so jumping off the downstream side would pull you into or uncomfortably close to an established turpentine which happens to grow on the upstream side, whereas there is a clear path all the way to penrith on the down side. There are all sorts of ways of rigging this up so you dont end up doing a retarded koala impersonation, but it would involve static rope to span two lanes and a lot more general faff. And how then, when the Highway still ran over the bridge, did the delinquent youth of the day stage their jumps as tourist buses drove past???

Someone draw a diagram to clear this up please.

So havn't set it up myself, but apparently there are 2 rings and good cam slots on grose side of hanging rock.
Abseil off the bar fridge to clip the rings and plug in cams, equalise them and the bar fridge carrots and fling it over lots of carpet on the bar fridge in order to keep the bar fridge there.....

Have Fun... dont blame me if you screw it up....

Have set it up twice. Timfreddo's info is pretty accurate, except we used the bolts (fixed hangers??) about halfway along the actual "hanging rock" to anchor our 2 main jump ropes and all the bolts on top and rings on back side as directionals and backups. Just make sure you use loads of carpet to stop your ropes rubbing on the front rock face.

It's also a pain to get the tag line across from your jumping/launching position to the anchors. You'll need this so you can bring you jump ropes back to launching position after each jump. You also need it to be twice as long as the gap.

good luck, but make your own judgement on the day!

Cheers for the info guys. It all makes sense and I'm sure that it would all come together on the day, however I'm still keen to do it with someone who has set it up before. I'm not looking for anyone to blame, or even "organise" the trip, just to have someone there to point out any stuff ups that may occur.

Loz & Tim...Keen?

Couple more questions,

How long are your jump ropes? Full 50's/60's?
Do you have to retire the ropes afterwards?
Are you best off using old (nearly retired) ropes?

Dave.

I can answer that. The factor of the fall is really low so the force on the ropes would also be low. The only way the ropes would be destroyed is with the scraping across rock which presumably we put carpet down to stop.

The fall factor is at maximum 1 as the length of vertical fall is the same as the rope however it's a massive swing so the actuall ff would be heaps heaps lower

I think you blokes should sleep in, go to the pub and spend the beer money on yourselves and have a great afternoon in the sun having a go.

Throw a watermelon of the top first and see what happens when it hits the talus, way cool.

SteveC,

All the times I have set up for Knapsack I have used the three anchors on the downstream side. They may or may not still be there. We used static up over the side with three equalised loops and two dynamics running through belay device and tied off. Swingee was lowered from teh top once finished and tied the ends into the haul rope on teh otherside.

exactly as I would think. Except I only see 3 rings out of immediate reach over the side on the upstream as well as 3 carrots in the guttering of the road on that same side. Statics over the side you say... so there must be carrots in the gutter on the down side also. I may not have looked there. I only recall looking over the side as that seemed the obvious untamperable place for them to be ala the upstream rings. I wonder what shenanigans these are used for. straight plummets out plummets?

A lot of people consider it very rude to publish someone's email address openly on the web where it can be picked up by spam bots. It's kind of like handing their phone number to a telemarketer.

Fair enough - My bad!

Cheers for the heads up!

Hi Dave,

So did you guys ended up doing the Swing?

There are a bunch of people including staff at SICG Villawood, that have done both jumps. Last time I was at knapsack, the bolts had been cut, but the rings over the side on the up side were there.

A few pointers.

Don't anchor off the block that sits on top of the peak.
Anchor from an equalised anchor stemming from the bolts on the Grose side.
Consider a back up line back up hanging rock to a tree.
Rope protectors help.
Try two ropes joined to an anchor, that is below the rock itself
Either drop a line for ascension after each swing, or (requires more initial effort) set up a pulley system in the bush behind the jump point so that swingers can be hauled up from a really long trailing line (more can go wrong)
Be careful - a small slip up can lead to a cut rope, falling off lost gear.
Ride in on a bike - its quick and fun
Have fun
Being the guy who sets it up is scary on the first jump.

As an aside, I heard recently from someone I trust on such matters; ... that the whole 'hanging rock' is gradually getting farther from the adjacent mainland...

That seems like an epic set up! The efficiency of that is pretty dam good - you could get a jump in every 5 or 10 minutes. You must have refined this set up over a number of occasions.

Alternatively you can go a much more simple set up with just the swinging rope (and a backup), the way you get back up is just to jumar back up the rope. Much more simple but a lot slower. Also, this meant we had to dodgely get the swinging rope back round to the jump point - not as trivial a task as you first might think. We set up a hand rope around the cliff attached to all the trees so that at least we had some protection whilst setting up again. Doing it like this, we got a jump in every 40 minutes or so.

PS Good to see the bike was not just dumped into the valley.
