welcome to the forum mate.......indulge yourself and good luck on the cs40/41... there are a few lads on here from Ireland just luck out for the rainbows..... they'll be there somewhere.

haha afraid not mate.....can't beat the stuff .... nice one for your input mate great example and very funny but lessons from it to be learnt..... the next post maybe something to think about then mate....happy reading.

glad you are mate i will post some more once my daughter is sleeping............. hopefully we can get you educated in it abit more then you can take your rigging to another level....

Adding hardware to your system...... Although lowering over a fork is ok its still not very practical...adding hardware such as pulleys will reduce the friction on the system making rigging run smother and more controllable..... here are just a few pulleys that can be used as either the main anchor of the system or a redirect to help guide a section away from an obstacle or to help spread the load of the weight in the system...... beware as there are other forces to look out for when redirecting. also adding small hardware again limits you on the loads......

nice one rich will look out for the fundamentals of general treework...

My understanding of the Rigging research by Chris Cowell etc show that in a locked off system the peak forces can be upto 10x mass. Obviously this can be mitigated letting it run. Just my 2 pence worth Dynamic forces can reach 10x the mass and higher if allowed i will get into forces in detail later on in the thread......for know i'm just showing how to minimize the variables.... thanks for your input mate....

basic rigging..... the most basic of all rigging is to use only a rope over a fork/V/crotch in the tree and using a slightly over wait groundy to lower it to the floor... (but keeping it small is always safe as groundys can't fly) or better still a couple of wraps around a tree would be safer(but bare in mind what type of rope you use for this) braided line would be better as its hard wearing and snag resistent unlike double braided rope's. also if the tree is being retained it may damage the cambium layer so beware and use other methods to avoid this. another simple little belay devise such as this figure of 8 is better, attaching it to a sling to the base of the tree will help aid both the lowering and the groundy....... but be aware that doing this will limit your size of the branch as you will be working to the SWL of the figure of 8 not the rope.

Choosing your lowering rope theres a big difference between using some old climbing line and a lowering line although the old climbing can still be used in small rigging scenarios its still advised to get your self a lowering rope designed for rigging...... lowering ropes come in many variables such as size and the structure of the rope so depending on how big you want to go to if your natural crotching, if your rigging requires a low stretch or a high stretch, these are but a few things to think about when choosing your rigging rope.... here are some examples of what lowering lines are out there.... from left to right we have 12mm marlow braid 14mm samson stable braid 16mm marlow double braid and 16mm marlow braid

My next post after this will show pictures of basic kit to complex kit used in the rigging world, But first i would just like to say that this thread is only being made to show how i and others use equipment to our advantages not so you can go off and lower the whole tree down in 2. so first before we go into gear i would like to say that knowing your equipments limitations and understanding force's, weights and how different species of tree react to rigging is an absolute must ..... pushing these boundaries without knowing this can result in fatal injuries....... Each component in a rigging system has what we call a SWL safe working load limit, these rating's should not be overlooked or overtaken...they are there for your safety. you will find them either stamped on hardware or printed under shrink wrap on rope or they will be on the certificate of conformity from the retailer..... understanding dynamic forces and with in the system including the tree is a must, but first you should be able to judge your weights of the species of tree first, this i understand takes time and alot of revising, but once you can do this then you will be able to judge how much force will be put on a system from eg, a 200kg log on a 1m drop would be a force of 800kg forces like this will become visible in the system as friction (glazing on rope) but forces like this can also be lost depending on how you execute the rigging load. eg, would be to make the shock load minimal by letting the rope run and distributing the friction evenly along the rope. adding hardware such as pulleys allows the rope to stretch to its own shape throughout the entire rope used evenly, hardware like a pulley will allow you to lower the dynamic forces compared to natural crotching. anyway just an insight but we will get technical later i don't want everyone to fall asleep on the thread just yet....

no worries mate, its good to help out others.... sounds like you were speedlineing of some description but we will cover this later on in the thread.... of course it is mate, as long as you can explain what you were doing why and how it was carried out just for those who don't know....

i heard you bought the one with little colouring in sections and little pop up pictures......

Right so why do we Rig? rigging or lowering is a term used to safely dismantle a Tree without causing damage to property, other trees, plants and animals (flora and fauna) to bring a limb back from over dead power lines or BT wires or even water ponds lakes rivers ect, or just for ease? in my 12 years climbing theres one thing i've learnt while practising rigging and that is it makes for a very safe controlled work environment and in some case's quicker than just crashing everything to the floor. in this photo taken from a still image from a video i'm dismantling an ash tree over a road and dead power lines, there were several components in this set up that i will run though later but the main reason for putting the picture up was to just say rigging only goes smoothly when full communication is kept all the time.... i'll put the video up later with a description of what was going on and how we used the drop and swing of the limb to our advantage..... when it comes to rigging a good climber is a must but a great groundsman is invaluable .....

Right so all you lot wanting to get into rigging or wanting to learn more then get your self on line or order from any book retailers and get yourself the Art and science of practical rigging, along with this thread(i hope) it will be your sole mate with detailed descriptions and pictures of equipment knots hitches and scenarios it is a must for any climbers bookshelf......

Right this is going to be my attempt at helping some of the newbies/semi-pro climbers out there wanting to learn a bit more about the rigging side to arboriculture. After reading a few threads on here its seems that there is little information out there without looking to hard. so from new guys/girls getting into arb or who have been climbing a year or 2, or even at college and wanting to lern more and even some of us experienced lads could also use a brush up or even learn something new:sneaky2: (yes it does happen we don't know everything but we like to think so:biggrin:). Right so what i will cover in this thread is more or less everything to do with rigging:001_rolleyes:, starting from the basic's to the extreme techniques. along the way i hope some of the other experienced riggers will also input there views, ways, and gear they use with descriptions of course..... i know there's loads of threads on the subject! but i wanted to a thread that was just dedicated to rigging so please try and keep the conversations aimed towards the title and try not to derail to much, and if you want to know something please ask! and if you want to add something, be it views!, pictures! then go ahead.....post away. so in a while i'll get some photos together and descriptions and make a start......enjoy:001_smile:

hilarious post mate..........nearly as funny as my post.....

i'm sorry i can not help you on the picture posting as i don't have a mac......but i hope you get it sorted soon and post some more of them pictures....beautiful.... so what was the story behind nepal visit? and sorry for the derail just really interested mate...

is this photo one you have taken? if it is that is amazing.....

good thread and some strong views and some not so "nothing to do with the subject" comments.... here is the thread from the owl carving in the Cedar... http://arbtalk.co.uk/forum/chainsaw-carving-forum/33892-clients-owl-carving.html .......... i Had nearly a whole page written out on what i was going to say about this but deleted it as there would of been another up-raw......i'm not one tell people they are wrong they would figure that out for them selfs.....nor am i one to think i'm always right ....when i'm wrong i say i am..... mother nature carves tree's in so many different ways shapes and forms....man made carving is no different from large deadwood on an oak tree for example .....the owl carving is no different from....lets say the wounds or tears left by a limb fall .........as Huck has said i see no reason this would be un-acceptable on your OWN Tree's..or for a great carver that has been asked and is working to standards legislations...but this is just my Opinion .......And opinions vary....

thats ok mate but change the crab for a mailon mate as there could be a slight chance of the gate opening on the crab.....

Agreed awesome mate.....love the shadow one very cool:thumbup1:

:lol: yeah been meaning to look up the black ones that would be a great way to colour code rigging and climbing at the minute i just etch an R into the rigging Pinto's i have just in case there all separate but being a subby they do tend to end up in your climbing bag not the rigging bag.... black for climbing for me as then all my other purple/pink ones can get used for rigging as that way it would work out better......

it is mate general chat about trees.....

Awesome mate:thumbup: daisy chain the loose till i need it and still years of life left in the first smaller one you did for me ....just handy to have 2 and another excuse to buy another Pinto Rig.... on the lime front tell them to get there act together mate...

the thread would of been better in the lounge mate? not really anything to do with tree work? but no not me and couple of one nighters nothing to bad:biggrin:

is that a bottle of carrona? Where is the piece of lime in the top haddas?
