All real arborists will be secured by ropes from above and wouldn't
be seen dead, anywhere near a ladder.

Well, you can save yourself some time over the first bit on a ladder
if you want. ;-)

Er no.

Er yes. You are talking about your fantasy arborist, I'm taking about
our daughter who was a trained tree person.

Its much easier for the arborist to put his/her feet through
the loops of the foot ascender sometimes called a knee descender as
the ratchet is at knee height, at ground level.

A massive assumption that all arborists use mechanical ascenders and
they don't.

And just as quick as
their upward steps are the size they want rather than being dictated
by the distance between the rungs of the ladder.

See above.

That's assuming a ladder is a possibility in the first place.

Of course.

With amateur
grown trees as are found in people's back gardens, with branches low down
maybe. But in all large trees in public places lining roads, in parks etc.
all the lower branches will have been removed at an early stage to avoid
obstruction

'Lifting' ...

and save the council getting sued by people banging their
heads. Possibly you hadn't noticed ?

Possibly you are making big and uninformed assumptions. After arb
college, she worked at several arb Co's, then for herself, now for the
local Council involved in the management of their 'Open Spaces'. She's
also one of few on their team with all her chainsaw tickets and so
still called in when such things are needed and they don't want to /
can't get contractors in.

I actually moved her climbing gear bag yesterday and I can assure you
there are no mechanical ascenders (or spikes) in there.

What difference would it make lifting a 60' tree from 6' to 8' re
initial access into to the tree by ladder?


Either literally or metaphorically.

;-)

You throw a rope between an overhead branch and the trunk and climb up the
secured rope, using one or more pairs of ascenders. Ratcheted devices
for feet and hands.

No, a 'real climber' would be using a ' Prusik' that they have made
themselves (and a cambium saver they had put up there with their throw
line if the tree wasn't being taken down). ;-)

I drilled a hole in a golfball through which I threaded thin cord
and threw that up in the tree. I assume that must have been my "throw
line".

Yup. Not so nice when it hits you on the head as a traditional 'throw
bag' but it would work.

As many ropes as required may be attached to that.

As many ropes ... are you building a web?

Which is something I do use all the time. Throw the ball anyway.

'Fetch!'

Obviously you've been googling but maybe not hard enough.

Oh dear ... ;-(

"prusiks"
are very basic friction brake devices made by winding rope around the
rope.

Well, not really, it's a loop of rope used to make a self locking
device to *attach* to the main climbing rope (using a Prusik knot or
hitch).

Real climbers would be spending hundreds on decent anodised
purple and green ascenders and descenders out of catalogues.

Oh dear. See how silly you now look as you dig yourself deeper with
your inexperience and uneducated assumptions? If someone is *just* a
tree climber / cutter then yes, they would probably invest in the
latest kit. If they only climbed infrequently then they probably
wouldn't (as some of this kit is very expensive and you would have to
pay to have it checked (LOLER) every few years).

Yup, and on the way down chogging, a wire strop / flipline (plus
mainline) ...

Chogging ? Another technical term ?

Yup, more Googling for *you*. ;-)

Is that repeling or absailing?

Neither. It's the taking down of the trunk in sections as you climb
down.

Wire strop, flipline, mainline ? Have you been googling all
this stuff ?

Nope, see, just because you have to, doesn't man someone involved in
the role over many years would.

Her b/f was an Instructor / examiner / NTPC inspector at an Arb
college for several years and I have had many interesting / technical
conversations with him (along with assisting both of them on tree
jobs). Plus it was good to watch all the climbing at the Arb shows and
competition climbing events.

Well yes to descend you er use descenders.

Or your Prusik ...

You also have what I call
a safety rope which I do use attached to a harness back and front
again running through a friction brake

All sounds very complicated. Are you sure you aren't talking about
rock climbing?

See, 'officially' you shouldn't climb on your own (now especially) but
many do and therefore who is going to manage the safety line?

although obviously yourself
and google will know the proper names for all this stuff.

Some of us who have *actually* been personally involved in it at a
professional level will know most the basic terms already of course.
;-)
