Large Elm Dismantle on the Bulldog bone.

We were called to remove a large Elm in the city centre of Oslo last week.

The tree had lost a limb the week earlier and had written off a rather expensive Audi, totalled it..!

The rear stem which failed was not looking the best and white rot at the failure point. We had rig the tree due to location and a crane was decided against due to the location, Tram lines, foot fall as it would have taken the space up needed for the trucks and chipper.

Timber was shifted with the Avant. We had a few gopro's on site and the boss had recently splashed out on a rather luxurious drone. So we snapped a bit of footage with that.

Another climber, Aaron climbed this one and fancied a go on the BDB, myself and two others ran the ground. We managed to get some good footage.

Anyway, enough waffle.

Watch in HD and I hope you enjoy.

Any questions feel free to ask.

 
Levi, thanks for the kind words. I just messed about with different angles and the boss turned up with his Drone. I stitched it all together with a blinding hangover on Sunday.

Monkeylove, I was the one running the ropes. We take it in turns climbing and my mate Aaron, fancied this one and he also wanted to do a proper job on the bone as he had only rec climbed on it till that date. He is a good climber though and took to it instantly. He has only been climbing SRT a few times other than for access.

Thanks again.
 
We have another large Elm with DED to remove on Thursday, we will have the drone all day so I reckon I will dibs that one. ;)
 
Nice job. Didn't you tie the 2 stems together when you felled the last cut? Seems they could have fallen apart if you had some bad luck. I hate the smell of cutting elm.
 
No we didn't tie the stems together. Although they split on impact there was about 2 - 3 feet of trunk below the union. I think the only reason they split was due to the union which was weakened by the Gob I put in there. As there was a fair bit of weight up there I made the gob cut pretty deep to help shift the CoG to help bring it over.
 
Mate, that is very easy to say from behind the keyboard when you weren't at the job.

Thanks for your concern though.


There were 2 very experienced climbers on the job and the boss who had checked the tree. We didn't deem during the onsite risk assessment that it was necessary to brace the stems. the riggin plan was to load share between stems. As you saw in the video it went to plan.

As I stated the reason the stems split was due to the impact and the amount of wood removed from the face cut.

Maybe next time if we come across a similar situation and we deem it necessary we will tie the stems together.

Cheers.
 
Sure mate tell yourself they fell apart on impact because of removal of the "gob". But maybe in another trend of thought think how easy it would have been to connect them before the last cuts and avoid a surprise.

I have seen this situation split enough times regardless of that span of solid wood. What happens? One side maybe goes into something and damages it ...or one side caves and pins the saw and it goes down with the trunk. I just stopped long ago, having not wanted to explore the possibilities.

I picked up a section last fall with my crane with a 40" trunk by one of the co doms above it, with at least that much span of solid wood between the split and the bottom cut from the ground. Half way to the log truck half the piece split off and went to the ground and the other section was still on the crane hook. Since no one is allowed under a pick and it wasn't floating over a house...no harm ...no foul.

But it seems a bit of dumb luck amongst 3 "experienced" arbs as you say...no one even considered this. I would have had I been on that job but I likely have more experience than all 3 combined.

Cheers.
 
totally different work environment then im used to, neat for me to see. tree work in the city seems more involving as far as job site planning and set up.
seemed like some smooth work other than the debatable decision with the stem. ive become much more preventative than i used to be after having a couple mishaps that should have never happened, so i personally side with the Vet on this, but more out of fear/respect for what could happen rather than cause ive been doing tree work since the dust bowl like Vet.
regardless, good work and thanks for sharing, hope you get some footage posted from the next one you did
that was almost like watching myself runnin' ropes...;)
 
Treevet I hear what you are saying.

You mention you picked a stem with one of the co doms and it split on you as you lifted it. Tbh, I am not sure what you are getting at. I would never pick a co Dom stem with a single lifting point. I would always sling or chain both stems.

So it was ok for you to do and that day you said you learned a lesson. No damage no foul.

The heavy stem split on impact, no damage no foul - but you are calling me dumb for having that happen when the risk of damage if any were to occur was minimal.

As for experience, you may have more than myself and the others put together as I can see you are in your sixties from your profile. Your still alive to tell many tales of cutting wood and I respect that.

I have said in my previous post that I will take your comments on board, what more can I say.

Thanks.
 
I think the luck was referred to as dumb my friend, not you personally. And had you mentioned that you CONSIDERED the ramifications of a splitting occurrence then my hole that devours pie would have remained hinged. Anyhoo ...best of luck to ya.
