Stein Dual 'Impact loading'

[Reg]

Stein Dual \'Impact loading\'

This was a 75-80ft Beech, condemned due to meripilus.

‘Protect our lawn’ was the word, so we did our best.
Thankfully I was able to tie-in and escape when needed to the adjacent beech....I also set up a support line to share the load when folding the top. ...I’d have otherwise had to go significantly smaller such was the extent of decay down below.

Difficult to let the sections run with them being quite long and landing close to the LD....but with the appropriate hardware we were able to confidently bring them to an abrupt halt where need be, hence the title. Some photos of the latter stages of the job....will take some time to embedd. Thanks

Last one

I hope you got some video on this one.
Looks exciting.
Were those two lower cuts rounded off like that to lessen the possibility of your load catching one?
Thanks for posting Reg

Yes and yes Jesse, I stuck the camera right under the LD when the top came over....its quite a sight.

You got some nice photos. 3-6 but #5 is the shot of the year contender.

Cool photos. Is there a benefit to using both bollards when lowering one piece vs. just one bollard?

That was a healthy top, bet you had some wiggle on that stem

[/ QUOTE ]Load sharing, there's the benefit. About 800kg in the log that we double roped, which we had to stop quite suddenly, fell about 4 feet before the ropes engaged....huge amount of force to otherwise put on one line/sling. When I put the video up you'll get the true feel of it.

In case I mis-understood. If you're talking a single line around both bollards as opposed to one, then yes....less heat when you put the first wrap around both. Not that we've encountered any heat issues but I just tell people to do ot on the big stuff all the same. Thanks again.

These days, protecting the lawn would've been very low on my priorities when removing that tree regardless of what the client wanted. Lawn can be easily repaired, people cant.

With respect Reg, I think you rigged way too big for a tree infected with Merip. What if the base of the tree had failed when rigging out one of those sections, aren't you putting your groundies and nearby structures at risk? Would you have still rigged as big if there was no other trees to place your TIP in?

Maybe I'm just getting old, I dunno

Nice work, Reg!



People preoccupation with their lawns amazes me. Isn't grass next to impossible to kill.

Seems like it would be waaayyy cheaper to bomb that stuff, and get a yard of soil and some grass seed than employ someone skilled enough and with the equipment enough to rig down trees. Rarely do I rig for grass... shrubs/ trees/ infrastructure, sure. People are strange, but they write the checks.


Reg, how many ropes do you go through in a year?

Nice work Reg!

Get some youtube vids up...I need distractions from HW

Hey Reg, do you need an apprentice?

Re: Stein Dual \'Impact loading\'

Great pics Reg,

I suppose you have a man on each rope when you are double blocking it like that? Dose it ever throw the log to one side or the other if the groundies are not in unison?

I have learned a lot from your posts and videos. keep them coming.

Thanks, Caleb

Nice pics and rigging

Re: Stein Dual \'Impact loading\'

Impressive stuff Reg!

That first big hang...What can i say???
I think Grover has a point, that,to a certain extent you put your ground staff at risk with such big hangs especially as the tree is declared to be un sound.
I know your showing the capabilities of the Stein dual(looks like a nice bit of gear!) but pictures of that head topping certainly raised my eyebrows!

I dunno, an established lawn is often much loved & i often find that rigging, even when you could free fall peices, can improove productivity & safety.

I thought we all rigged that big when needs be & that we all have to rig down diseased trees, what better tree to practice on than one that you can set up a load share line & anchor your life-line into a neighbouring tree?

Rigging exerts much lower forcs on the tree than the wind, the forces are typically close to compressing the timber along it's strongest axis, this is well documented.

Sharing the load with 2 systems more than ensured the strength of the system (the dual is perfect for the job) but another other buzzer asked the interesting question of how many ropes reg goes through? pushing your rigging kit will accelerate the CTF which is fine providing you replace your ropes frequently enough, other industries put far more emfisison CTF & periodic replacement of gear.

The only thing that could have reduced the load on the tree & equipment a little better would have been to tie those couple of peices that weren't closer to their balance point, reducing the shock load. That said, it wasn't esential as reg wasn't pushing it that much & most of the peices tied close enough to the BP, nice rigging reg

Re: Stein Dual \'Impact loading\'

If you reduce the size of your hangs by half you could probably reduce the size of your rigging by half!

Re: Stein Dual \'Impact loading\'

quite, if in doubt keep it small

if you have the knowlege & experiance you can get the job done twice as quick! just as safe!

Re: Stein Dual \'Impact loading\'

Reg, have you (or anyone else) ever put a dyno on each block at the same time to see how close to being equal the forces really are?

Re: Stein Dual \'Impact loading\'

your groundies would have to be in sync if there were 2 ropes being used at once.

but the amount of weight you could lower would be staggering.
