I'd use a cambium/friction saver - there are a few adjustable ones around and it means you don't end up mixing PPE with rigging kit. If you do that you really should submit the whoopie for LOLER every 6 months - additionally, the whoopie is likely to have been subjected to extreme loading, something your PPE should NEVER be suffer and, in the event it was, then it should be retired from service until it has been thoroughly inspected by a 'competent person' in accordance with LOLER 1998. I've always though that mixing PPE & rigging kits is the thin end of the wedge - just a thought. Andy

Hey up Fuda, Nick is spot on - loads of different hitch combinations are available and there's a decent section here on Arbtalk with step-by-step guides and there is some decent cordage out now which is specifically designed for use with the Yale rope range. AND,whatever system you go with, a cambium/friction saver is one of the best investments you'll make. It'll save your rope, your arms (reduced friction) and the tree - good news all round really. Cheers Andy

Reg Coates is a good place to start - you just need to be sure you get the English version of the clips! The main criteria are that the equipment is fit for purpose and compatible with other components in the system such as the correct rope diameter for the lowering device so the bend radius is not compromised. Anchoring cordage is important and should be over-specified where possible but I've also seen bigger rigging systems abused until even they fail due to over-loading and shock-loading. Vectoring a load when lowering is an easy way to reduce component strain and improves the working life of all the kit used and, like Majestic says, there's a good bit of decent information available. Good to see somebody interested in doing the job properly

Just a thought - this kit must be submitted to a competent person for a thorough inspection at least once each year. Any equipment for which you cannot prove compatibility or conformity should be recorded on the inspection sheet as not fit for purpose - that would make any investment in that equipment a waste of money. If you source, purchase, configure and use your equipment sensibly you will set yourself above the 'cowboy' tree worker and contribute to improving standards in the industry which will lead to a general improvement in rates/earnings which will enable you to invest in better equipment on a more regular basis. Good kit, well maintained, will last longer, makes your job easier, more productive and safer. Can't see any negatives in there.
