Thankyou so much for the interest Morten, and yes, absolutely we’ll be in touch with you just as soon as they’re ready. In fact, we will actually have a range of 3 devices available but if you haven’t yet seen the Dual in action then here’s a couple of quite recent videos… http://arbtalk.co.uk/forum/video-forum/8125-lowering-device-project.html http://arbtalk.co.uk/forum/video-forum/8947-beech-rigging-video.html I think the beech video especially highlights the main incentive for having 2 bollards on the one device.

Video editing really is a boring, uninspiring task….especially when its your own work that you’ve already had to experience in reality. So thank you all for the interest and kind words of commendation….it does almost make it feel worth while after all. Tim, from what I was told the tree was condemned as part of an insurance requirement, although how true that was is anyone’s guess. Marc, it is essential that both lines are tensioned and that the lower rigging point/block is positioned as close to the cut as possible….this is what restricts the logs movement at that end after the cut has been made. Notice also that the cuts used were step-cuts but with the back-cut above the front-cut to stop the log shooting back at me. The technique should be avoided if ever free-falling wood though, as it can take your saw with it (for anyone who didn’t know). Steve jnr used the two spars to stop the momentum of the rotating log….had he let-it-run straight away it probably would have wrapped itself around the trunk and gotten us in a tangle. On camera it looks quite dangerous which is why I slowed it down for extra effect, but in reality it couldn’t get through to me…. Thanks again

Here are the videos’ of the job I recently described in the Picture forum. Nothing too exiting but the methods were sound and the job finished on time. Thanks Part1 [ame=http://www.youtube.com/watch?v=T19AHQnhzB4]YouTube - Beech tree Rigging part 1[/ame] Part 2 [ame=http://www.youtube.com/watch?v=ehbSFnlDDfU]YouTube - Beech Tree Rigging part 2[/ame]

Thanks again all. There will be video of the job at some point. Yeah it was good to talk Rich. I think the show was worth while, with all but one fella over the 2 days that bugged a little. Combined-tree-service, I'm really not at liberty to say anything just yet, I'm sure you can understand. Cheers

kind of

Thanks guys Like wise Chris, and no improvement yet I'm afraid. Yes I did bobby, will give a much better sense of scale than the photos....although it'll be a while before I can get round to putting it together.

I'd not realised you could post more than 5 pics at a time until just now, so here's the rest. The last 6 ft of trunk had wire embeded all the way to the ground, so I had to sharpen after every cut.

another 5

next 5

And more

More photos

Here are some photos from a Beech removal this week. It took about 18 hours for 4 of us to safely bring the tree down, chip the branches, saw into firewood and remove from site. The weather was constantly changing with heavy rain one minute and sunshine the next. The tree was set between and over 2 buildings while slightly elevated from the parking area with a retaining wall about 5ft out from the butt. We Rigged everything but the last 20ft of trunk which I was able to chunk down into the dirt. A good size landing area meant I was able to rig down some full size limbs, some were double-rigged over the building which worked well in this situation. 39 photos in all. Thanks

They're real good Matty....and especially comfortable with spikes etc.

Thanks Dave, Carl and everyone else who came over to say hello....it was a pleasure to meet you all and I just hope next time I can do it in a more relaxed state on mind....preferably with no LDs involved. -------------------------------------------------------------------------------- Absolutely....we had done it many times in the past but the set-up time is slow and sloppy where the portowrap is the second device involved....at least for one groundsperson managing both lines.You made a great choice with the GRCS though, I hope it serves you well for many years to come. Re: the subject of this thread - if its ok I'd take a rest from it for a while as for 3 days Ive spoke of nothing else. Thanks. Reg

Its heavy enough, although I dont have the exact weight to hand. I was begining to give up on that idea, until a much smarter guy than myself suggested on another forum that I should simply hang it on a nail first.

Carl, forget the GRCS and my device for that matter....sounds like what you really need is a Hobbs lowering device. And you know what my brother, I might just be able to help you out there!!!

Carl, the lever offers a fast lift at 2:1 and a slow one at 5:1. By utilizing an extra pulley and prussic the ratios are further doubled to 4 and 10:1. There are numberous combinations that can be used to achieve a desired effect. An eyebolt is also set on top of the frame for a fiddle-block option. Personally speaking, the sort of trees I encouter rarley need lifting anywhere.....some pre-tension for added guidance, but after that there's only one direction there headed and it aint up. Thanks

Not my department I'm afraid....although Stein are an ambitious, relatively young company who dont do things half heartedly.

Thankyou all for the kind words of encouragement, they are much appreciated. Combined tree: I’m pretty sure they will retail around £500. Timtree: I don’t have an exact date but will have a better idea by the end of the week. Atree: I’ll try to elaborate a little on what Ben said earlier. Wrapping around both barrels ensures less rope twisting, better heat dissipation and overall control. For reasons unknown to myself, the technique also allows the operator to draw much of the slack out of the system that incurs when folding over a log….the technique obviously requires practice and specific routing of the rope….and for heavy chunks is more achievable with 2 persons pulling out the slack (see falling pine log late in the video). I would like to take credit myself with the facility but that’d be dishonest….so its just an added bonus which was discovered by chance. Utilizing two ropes at the same time is really down to the task at hand and the preferences of the workers involved. FWIW, I’ll give you my incentives and try to explain them as best as I can: Easy balancing option needs no explanation really. Speedlining is another obvious one where both the load-line and control-line are tended by a grounds-person at the bottom of the tree. Load transfer between adjacent trees or rigging points. Holding the butt close to during and after a cut is made may also be desirable where limbs are being cut in there entirety i.e. if you have chosen a rigging point that is way out from the limb that’s being cut, it might be the case you cant can’t afford to let it free-swing towards and past that point due to the risk of a collision with an adjacent property, cable of whatever other damageable within the pendulum-swing….so the second rigging line is used; also, opposite scenario is where you desire the to bring a horizontal to the floor while maintaining its original alignment but the rigging point is in-line with the climber position….here you run the risk of having the butt shoot back at you if the limb is balanced….so the 2 nd rigging line is again utilised to hold the butt in position and stop this from occurring. Good examples of the latter start from 3:00 in the video….although one must always remember that the second rigging point must be set up as close to each cut as possible, so the amount of movement afforded to the butt is minimal, so it may be necessary to re-position the rigging after each cut. Further still, the same set-up can be used to isolate and draw large horizontals through the middle of a crown and out the opposite side….where traditional a climber might look to systematically start low down in the tree and bend balanced horizontals round in a wide arc. In most cases this standard practice works just fine….however there can also be adjacent obstructions such as neighbouring trees etc which can render the system impractical. However, the double rope technique I describe means you can pretty much start anywhere in the tree (within reason), and draw the limbs out of the crown while maintaining their original alignment so to avoid snagging. In the last three examples one could argue “why not just cut the branches smaller?” Well, if you could fall a tree in its entirety you would right….9 times out of 10 there’s is nothing to gain by climbing up there to dismantle instead. Same principle applies here, assuming sufficient manpower is at hand of course. What more can I say, when the option is at hand you do start to recognize possibilities to make the job easier. Moving away from that device from a moment, here are some photos of the smallest in the range....although not so small in reality. The sequence of photos show the mounting and rope-routing. You'll notice that the device utilizes two ropes (although you can stick to one if so desired) for the convenience of the groundsperson. The top rope is not load bearing so it need not be an expensive sling like the one in the photos.

Some Still/Moving images of the LD, merged together to make a nice little video. You can see this device plus 2 other smaller designs at the Arborist Trade Fair (Cirencester) at Fletcher Stewarts stall this coming Friday and Saturday. If you are planning to attend come say hello.

Last few

More photos

I returned home today having had 7 fabulous days down there….beautiful country indeed. Great to get away from work, shame it couldn’t have been longer. The images are from Mortehoe (where we stayed), Woolacombe and Clovelly.

Yes sir it is. Thanks

A Fixed Single Bollard will also be available for round about the £200 mark. Plus a smaller Hanging version (not shown here) which I just finished last night to complete the range. All 3 will be on show at the AA trade fir next month at Fletcher Stewarts stall, and will be available to purchase from Treeworker and FR Jones amongst others, all being well.
