What are you going to do with the tree once it's craned? If you're going to load it straight on a lorry and away then it will save a bit of time, if your going to ring it up and hand load it onto a transit then not much. All depends on the access to the tree really, if it would be a long nasty drag the crane will be a time saver, if itsroadside it's a bit pointless.
-
Some good points there, have you tested the DMM to make sure it won't break your teeth or is that purely speculation? Any volunteers to be whacked in the face with several different pulleys step forward now.
-
In that case its probably a Tarquinodendron felixensis. Suffering from a nasty case of Bombay Sapphire disease.
-
Does she think she knows what it is? If not then just make up a name, something really obscure, invent an equally obscure disease that its suffering from, and tell her it needs to be felled to prevent the imaginary disease from spreading. Sorted.

What hitch and hitch cord do you use? A friction hitch cord with a high melting point will burn your rope more than a cheap polyester type cord.
-
Easy solution to that, get your appointed person ticket and do it yourself.
-
Surely you mean the contractor's insurance? The climber doesn't need any insurance, other than maybe personal accident cover. Every crane driver/climber combo must have worked together for the first time on something, what would you recommend for a first job?

Hi JON Pete not so sunny here Cambs hard cord wood 500 mm plus here pricey too large biomass less work surely living has be made give up maybe? What do you all think?
-
I wouldn't use a pulley if you can avoid it. Friction at the anchor point is twice as useful as friction generated by taking wraps around the trunk. Definitely avoid the topping strops!
-
Stick to natural crotch rigging and trunk wraps and you'll be fine. It'll be like going back in time 20 years!
-
Can't really find any proper info on it. What I would want to know is the melting point, as I would expect it to be very low. Polypropylene ropes do not work well with metal lowering devices for this reason. If you just want a big fat cheap rope for pulling trees out of swamps then it's probably ideal, but for any application that involves friction it's basically a ticking bomb.
-
Normally it means both parties sit down and discuss the issue at hand, to wit, pay, and reach a mutually agreeable decision.
-
Thanks! Not quite, the hierachy is avoidance of work at height, then MEWP, then climbing.
-
I think the large area of dead in pic 3 is unrelated to the fungus, probably an old machine strike. The brackets at the base of the tree were at least 3 feet across, so it had been at work for some time. It did crumple a lot on impact, so definately something going on further up.
-
No, but the decay didn't extend as far into the stem as I expected, I thought the whole diameter of the decayed part at the front would be mush, but everything except the bit that fell out was pretty sound.
-
Hard to say really, I think once the tree has started to break the hinge fibres they pretty much all fall at the same speed. There wasnt a lot of live wood in the hinge though.
-
If the mewp is specified as the rescue method, and it can access the whole canopy, what is your justification for using a climber to carry out the work?
-
Field side, as was the decay. Looked fine from road side, so much so that it was deadwooded roadside without the decay being spotted..... Weighted towards the road.

Ash fell.

Gunnera manicata can get up to 6 feet, leaves usually 3-4 feet across, but the flower spikes are normally shorter. It has round stems with short spikes on. It is also frost tender, so the crown needs covering up with the cut leaves in autumn. Rheum palmatum looks just like the edible rhubarb, only bigger. There is also a purple tinged leaf variety, called 'Atrosanguineum'. There are other species of Gunnera in cultivation, but they are quite unusual.

If all else fails, buy a Big Shot!

Practise, practise and more practise. I use a permanent loop tied in the line, on one finger, and swing the bag to my right. Any technique is ok though, find one you like and take some time outside of work to get it right.

Ariel rescue- THE method for rapid ascent.
Peter replied to Tony Croft aka hamadryad's topic in Climbers talk
Cool, I'll see you there too! I'll probably be footlocking in to the tree, although I have no idea what the scenario is will be. When you have 5 minutes ticking away, it really shows up any flaws in your system, so whatever you are going to use make sure you are really really familiar with it beforehand, you need to be able to set it up with your eyes closed! -
TW 190 seem to munch conifer quite happily, as long as the knives are nice and sharp.

Looks well smart!
