Negative rigging friction location

[AHPP]

 

6:51 onwards as an example of a cleated off dead stop where the climber does everything. But there's nothing stopping the groundsman controlling the tail from the floor. Except it jars with everything we're used to.

Id say there is more potential for the lines to get crossed or pinched, making for a very sudden stop, then hard to add or remove a wrap if its too heavy/light? Also, if you have already rigged out the brush with a high point, porty set up at the base, just crack on moving the block or ring down as you go. But Id say alot of the reason is us being Magpies.

Alother thought, rope weight going up to the porty at the cut could significantly affect how a wrap functions, adding another complication. 

I do like yo yo rigging though. Perfect length line so the tail is back to you as the piece hits the ground.

I think it will just over complicate things inmensely.

 

A good trick to have in the bag when needed but not necessarily one to be used daily.

 

About 16 years ago I was working for a firm and me and the other climber reduced a massive London Plane tree over about 8 gardens.  
 

Nearly every piece had to be rigged so we took a lowering device up the tree and set it up and just moved the rigging pulley around sections of the tree.

 

After about 3 or 4 attempts we decided it was a waste of time having it in the tree.  It also wasted the time of the climber using the device when they could had been else where cutting.

 

Lastly, it was no benefit to the groundsman.

 

Granted that scenario was for the tip reduction of a large spreading canopy and not in a stem.

 

I honestly just see it as extra hassle Alex.  Nothing to do with it jarring with what we have been told.

 

Having the move pulleys down a stem when negative rigging can be a bit tricky the larger you get.

 

Then you are introducing the need to reattach the lowering Device for each cut.

 

Or you could just position the lowering device in a place that only needs to be moved once?  Such as the bottom, I.e when you’re finished.

 

Oh, hang on, isn’t that how we have been doing it for years:  ?

In addition to the above you are removing approx 50% of the length of the working line.

 

We all should know on sketchy trees the more rope is in the system the safer it can be.

An even simpler system is just telling the customer the lawn ‘may have a few dents in it’ and avoid negative rigging completely.

[Rich Rule]

Rig it negatively and charge accordingly for a non impact job.

 

Count the monies, get your mates

to help as there are more numbers than fingers.

 

Job done.

Could do it. 

Things like this do the same job but more expensive: 

I preferred to have a groundie who could run lines when I climbed commercially.  
 

That in a nutshell , I would not want to imagine the ball ache of having a portawrap in a tree , safe bloc is more than capable and easy to reposition and no hassle. 
sorry for posting this again , but to me it proves the simple beauty of the device that has all

the benefits you want or need in this scenario.
