A fall of 2m in a work positioning harness would see the human skeleton start to break up - broken pelvis, snapped spine, severely torn ligaments etc we really shouldn't be talking about fall arrest when it comes to treeclimbing but I get your point re Kilonewtons.

thanks Chris, that info is worth remembering.

Can the Treemotion be used for rescues then? Rescues where the victim is attached to the rescuer's harness due to the victim's harness being damaged beyond use? you could put a mast on that burger and sail it down the Thames -

very good, thanks for posting, looked like a good crew getting an honest day's work done.

People can express an opinion on a product anywhere they choose to do so regardless of wether they have contacted the maker/dealer previously.

Andy is the drawbar on the 518 similar to the old 528s height adjustable drawbars? the older 528s drawbar and trailer chassis design seem bombproof. Found this pic on the web - not easy to make out the drawbar, but it joins the chassis under the engine rather than at the front of the engine. Will see if I can find a better pic, not sure why Jensen changed the trailer design on the 530s? maybe to get the chipper chute nearer to the back of a chip truck etc. They also lowered the height of the chute on the 530s which meant it became impossible to fire chips over 8ft high fences and walls - which the 528s are excellent for

Rhys, I dont think there is enough emphasis on tree care, or how your passionate about trees etc. If someone values their tree(s) a great deal and wants a sympathetic reduction etc they will want to know you are knowledgable about how trees grow and how you understand that the tree is important to the client. Having worked in your area for a tree care company I know that there are many people like that in the wealthy neighbourhoods where you work. I would include some shots of nice looking trees, still photographs, you have to seperate yourself from the other companies out there. It's not enough to show a big Pine removal, most folk want to know about you and what kind of person you are, they dont generally care about a tree surgeon knocking lumps out of trees.

Aspen, I may have met you at a previous APF and if your the guy I'm thinking of then you seemed like a very intelliigent person. You were the guy who did the demo with the bits of polystyrene dropped into regular unleaded then into Aspen, a great demo that speaks volumes about your product. The first aid kit attached to a combi can is not a good idea, its a bad idea. Forget about the first aid kit before you realise it was a bad idea and you've wasted money on it. No disrespect, but it's quite apparent that you have never worked day in/day out in the field of arboriculture, I could be wrong about that, but putting that first aid kit on that combi can is one of the worst ideas I've seen in a long time. It would get filthy and damaged in no time regardless of the bandages being sealed. Every tree surgeon I work with carries a blood stopper or small first aid kit on them at all times, and a proper first aid kit is always on site. There is no need for the combi-can first aid kit. The combi can on it's own without the first aid kit is an excellent idea, coincidently I am seriously considering moving to Aspen and would definitely buy the combi can device. Sorry to sound harsh but that is my opinion.

Yes, its true, I hear they've even stooped as low as using defunct Ford Transit engines to power them.

Ok Tony, maybe this would help Duncan in his research - Mechanical stability of trees under dynamic loads -- James et al. 93 (10): 1522 -- American Journal of Botany

Heard India was into this whole counterfeit thing as well..........apparently they're trying to pass these off as genuine off-road motor vehicles

Tony, Page 86 of Modern Arboriculture is right in my opinion, I have split wood many times and have seen exactly what he is referring to. Your belief in Duncan's paper is based on faith. My belief in Shigo's model is based on experience. Remember Tony (both of you).........human progress is an illusion.

do you realise how stupid that sounds? does Duncan understand Shigo's model? .

Shigo's model of lateral branch attachment is correct, you can't argue with it........from a Cedar log -

Warning regarding the presence of counterfeit versions of Petzl products | Petzl

Just had a chance to sit and listen uninterrupted. Duncan better have a very good explanation as to why Shigo's model of a lateral branch attachment is wrong. I find it very unusual that he would say this is the case when his project was part time over a year meanwhile Shigo spent a lifetime dissecting and studying timber. I think Duncan may have made a mistake regarding this issue or at the very least.....misunderstood Shigo's model. There is very little if anything Shigo has been wrong about.

Has it been seen north of London?

some pics, black zone lines seen across felling cut. Never got a decent pic though.

Phased reduction? not possible with that tree as large scaffold limbs were overhanging public path. I think it'll regrow despite its age.

been using the 4800kg 'Jet Rope Hoist' for the last 3 years, been excellent.

Wonder if Duncan has ever heard Mattheck talk about included bark unions, describing them like the Stasi's ears......big and always listening. Cheers for posting

Vid 1 - 1 min Storm damaged Beech most likely failed due to being severely weakened by the presence of Kretzschmaria deusta at about 8 metres. Included pic of Kretzch (next to secateurs) for those who havent seen it before. The top landed down a steep embankment which made dismantling a lot of fun [ame=http://www.youtube.com/watch?v=naZ9tjHiNv0]YouTube - Kretzch Beech[/ame] Vid 2 - 30 seconds This Beech had recently been shedding large scaffold limbs near a public path, infected with Ganoderma - its time had come, no rigging needed, tree left as monolith for habitat, who knows it might even regrow - [ame=http://www.youtube.com/watch?v=25w4OHuZ8Fc]YouTube - ‪Gano Beech‬‏[/ame]

tragic news

Nice job Steve, any signs of fungi at the base of the tree?

Incredible work there Reg, hope you were seriously rewarded for that, I'd have paid you £800 for those 4 cuts, £200 per cut.....anything less is a scandal. Cheers for posting pics.
