2 Days Ago
I learned the taught-line hitch in 1969. Using manila rope. I'm here to tell it was the best damn thing going at the time. By the mid 70s synthetic rope (nylon) had essentially replace natural fiber rigging in the arborist trade. The Blake's hitch came in the early 90s and solved the problem of the climbing hitch creeping. What a godsend. In the mid 90s the French Prussik with the minding pulley improved climbline control dramatically better. By the year 2000 numerous mechanical devices were being developed, in the attempt, to surpass the current limits of climbline control through fiber on fiber.
Up to my injury, and retirement, in 2007 I tried out practically every mechanical device there was, and in my opinion none of them could beat the control I could get through fiber on fiber.
But that was 10 years ago. Since then a half dozen new mechanicals have made their debut, and I can not help but wonder if they are really as good as all the hype says they are.
With the current development of SRT in working arborculture today it appears the mechanicals have reached a brand new pinnacle in line control.
