First bit rigging kit

[Gray git]

Minimum a Buckinghams flying capstan next a rc capstan but ideally a fixed bollard even if it's the smaller rc2001 you won't regret the investment and it'll last for years when you need it.

If you cN stretch to a bollard it would be worth it, very fool proof so any idiot can use

The guy is just starting out I take it. Why a bollard? Just take things one step at a time. Use a flying capstan. Get the basics down first. Walk before you can blah blah!

Capstan Is harder to use , I've watched groundies struggle and some get rigging a capstan wrong resulting in lines locking off or virtually falling off... You can't go wrong with a fixed bollard or floating one like the rc1000 as james said they are fool proof.

Well if the groundsman is f++k1ng that up, teach him again. They arent hard to use. Quicker to setup, versatile. My groundsman cant tie a bowline but he can use a portawrap any day of the week.

All down to finance I guess, I have always gone by the "buy once" philosophy, when you are a freelance climber you meet all kind of guys on the ground used to all kinds of things, for me a bollard is simple and robust, saves me getting snatched about. But like i say if money is a problem any other device is better than nothing.

Ended up with a fractured knee cap due to a momentarily lapse of concentration by an experienced groundsman locking of a flying capstan accidently. Never had a problem with any mistakes with a bollard.

As soon as you're rigging down decent sized timber you're on a job worth several hundred pounds at least.

Not worth trying to skimp, bollards aren't that expensive and are miles better than portys which flop around the base of the tree like an electrocuted fish.

I've just started getting rigging stuff, got the RC2001 bollard. I like the rubbers, so can be used to just take off big limbs and leave the rest of the tree alone for another day.

 

Only thing is, skimped a bit, could have got the biggest one RC3001. Now working load limit is given as 2000kg, what diameter and length of timber (say beech for example) and falling through approx what distance before the fall is arrested by the line through the snatching pulley, would be required to break off the steel tube and cause a catastrophic event for all involved?

I would like serious answers, with calculations if possible, along the lines, 8ft length of 3ft diameter beech falling half a meter before the weight is fully on the pulley and bollard.

 

Just want to understand when I really would want a bigger one!

That's a big piece to be rigging off !

As I understand it, without working it out I can only guess the weight of that size of timber but a object doubles in weight ever foot it falls when you come to stopping it.

So something 100kg falling 1 foot weighs 200kg, if it falls a further foot it weighs 400kg, another foot 800 kg.

So with a piece of beech like that which I guess could weigh approx 750kg, you could soon get up to your working limits.
