I cant remember the exact figure from my rigging ticket. There is some good research by the hse on rigging forces. They were dropping some big sections and I think it was 4 to 6 times the weight of piece. Its a few years since I read it so best check for yourself. The pulley doubling effect is why things like the safe block and x rings are popular, and natural crotch, as they add friction at the anchor point and don't double the loading. J.

Sorry jules, you are totally wrong on this, very unusual for you to make a wildly inaccurate statement. I decided to do a we demo. Photo 1, drill on weighing scales. Approx 2kg. Photo 2, drill on pulley with rope, approx 4kg. To hold the drill steady, you have to apply a 2kg downward force on the other side to oppose the 2kg drill, total 4kg. RIGGING POINTS EXPERIENCE DOUBLE LOADING VIA PULLEY. J.

Hi Pete, I was just expanding on your answer for the OP.

Two times loading only applies to a static load. When pieces are freefalling (before the slack is taken up) the forces multiply significantly. Up to 12 times the weight of the piece, although up to about 6 times is more the norm. With a good groundie letting stuff run and slowly decelerate that greatly lessens shock loading the system. If you have a 100kg piece, rigged from below, with 1 to 2m slack, stopped dead you could create a force equivalent to 600kg on each side of the pulley, meaning 1200kg at the rigging point.[emoji15] Something to think about.

I got given a pair of old North face gore tex salopettes, they were great at keeping me dry. They were a bit nippit when I got them and after a few years were too tight, so i passed them to my groundie. I now have some bergaus ones that were over £100 new, and they work fine too. J.

Coombe Abbey is a great place. I grew up near there, I saw beechwood yard when I drove past with the family last time I was down visiting family. There were always some big fish in the moats there.

Lubricant treatment for hedge-trimmers... worth it?

Poorly pole saw. I've ordered a battery husky to replace it, anyone want this echo ppt for spares etc?
-
In a word, no. Great pics of the paving but barely see the trees, especially the leaves. I need a close up pic of a leaf.

Hi, i can't be online at this time. Will it be available to view another day?

I don't have personal experience but have seen photos of hornbeam pollards that look quite healthy. I think they were pollarded commercially in the past. There is also an old thread on here "Hornbeam Pollards". If it's that or lose the tree then pollarding is the better option. Jan.

Delivered?

Hi, Yeah doesn't sound great safety wise. On my first aid course the guy had these transeivers which worked anywhere, they weren't cheap but were what he recommended for lone workers. In reach Explorer and Spot locator. I took a pic of them in case we ever needed it, but never have. They were a few hundred quid to buy then you need a yearly contract. Hope that helps. Jan.

Can you identify all the tree's/shrubs in this picture?

The "climbing arborist" guy might be worth contacting via his website. Isn't Reg Coates on Va island? Looks awesome out there, beats connie bashing for mrs miggins in the UK! All the best with it. -
Brilliant, I'm still chuckling at that. [emoji13] [emoji13] [emoji13]

You have messed up there, if you're subbing you don't steal the client. Especially if you're still working for the guy. Bad form mate!

Shiply are quote over 600, I included a photo of the chipper and di.ensions so they should know what to expect. I'm not paying that much anyhow. J.

Nightmare, will keep an eye out in Fife.

Tw160, tow bar might be removable, never looked into it. I think it might need 3or4 pallets anyway. J.

I had a look at palletline. The chipper is 3x1.5x1.5m, which is about 5 pallets, cost was about 500. I'm not sure they will take a chipper either. J.

wow that would be great, I will look into fully.

Hi Folks, So I have someone keen to buy my chipper (through Arbtrader). He lives in Wales and I'm in Scotland, which is about 430miles and 8hr drive each way. Apart from us driving halfway any suggestions for economical ways to transport it such a distance, ie haulage firms, car transporter? Cheers, Jan.

The guy I work with has a t540i, I have used it a bit and very impressed with it. I borrowed it to reduce a tall connie hedge, it cut through 6 inch connie stems easily, performs much like a petrol topper. We used it all morning and the battery gave out just before lunch. We filled the transit with 2 loads of chip, off 1 battery. He has ordered another battery as you'll need 2. Not tried doing a full dismantke yet.
