I have been tutoring a bunch of students climbing and pruning 2, we set up a simple speedline so i thought id show you how it went. Everyone was surprised how easy and efficent speedlining can be. These pics are of Roy, one of many of my star students haha Any questions, fire away. |

| Lowering rope takes the fall, section is stopped and held up, speedline is tensioned, lowering rope is slowly released to allow section to be speedlined to the ground. Sometimes a tag line is also required to pull the section along further. Considerations, force on tensioned speedlines at knot end or tensioned end can be up to 5X the weight of the section. Very well done Jim, nice pics. Get some more! we'll start a whole section up called ANZAC's (Australia New Zealand Arbor Champions) eh?

Nice setup, ideal tree structure as well. I dont want to appear to be highjacking your thread Jim1NZ but I do believe my question is relevant. How many times does anyone actually use a speedline system? lets say over a 12 month period. This thread has just brought it to my attention that I have not used one in over two years. I am not sure if Perhaps I just haven't recognized the opportunities or what. I also seem to recollect a preference to using them when we've been somewhat under-manned, perhaps in an attempt to reclaim the loss of that extra pair of hands. Ive also had several experience's of colleagues 'going to sleep' instead of concentrating, perhaps because of the lack of physical stimulation during the process. What do you say guys? |

I used one two years ago at college! Not since. But I did use a verticle speed line, now that puppy has a place in everyday use especially on a hill. Have you seen the video? Saved some windows by inches oooooohhhhh, I'll have to whack it up in the video thread.VSL is king!

Yeah, post your video, that was Lumberjack that hounded you but we run this joint. Anyone picks on Rangitata's video I'll do naughty things to your avatar. I got some bad ones like some guy one handing a saw.

I just depends on the sort of work you get. If you get the hairy stuff with no safe landing spots then how else you gona do the job? Crain yea, helicopter yea but you gota weigh up the costs of course. I think they are great, little set up time if you have used one a few times, very efficient and make the job soo much easier. Im not that into dragging brush up hill and out of some ones garden so i dont think my groundies should have to if its not necessary. |

Speed lining, the most over looked value of rigging. Not only will they bring things down and over to where you want it faster but you can also bring things over stop it mid-air bring a sling down then lift it back up. I love the whole idea of them.

I do a lot of speedline and drifting all the time. But still old school, to know when to just get the job done. Great job. Scotty |

Evergreens really lend themselves to speedline. I have in my head speedlineing to my crane and then lowering but have yet to find the application.

Be nice for back yard tree with no access, set the crane up in the front for your anchor point. I would try it. Scotty |

wondered what you use to tension the speedline up?

I'm just a very rookie climber and used the speed line twice and really liked how it worked. Like you said, it's easy to set up and keeps cost down and makes the job just as safe when it's done right, no damage to property, easier clean up, etc. Just my 2 cents as a rookie. It's also neat to watch. |

Dont forget guys, a tensioned speed line can exert up to 5x the weight of the cut piece at the ends/termination knots. So dumping onto them really compounds the issue.

Tention with a 3 or 5:1 works well, with a GCRS or vehicle but this is the LAST option as you can measure the tension being applied accurately. Remember the side loading forces in speedlining are something to know and respect. Speedlining is a controlled lowering system, it shouldnt be abused by cutting out pieces streight onto the main line. As Ekka says 5x yea well thats the thing, it could be 15x who knows, sure you can do testing but every single rig is different. Just stay well within the gear, the trees capabilitys. |

And dont forget there is always vertical speed line if you need to block down chunks on a hill etc ... stops runaways. Vertical speed line, a nice trick

Thanks for your comments Ekka and Jim1NZ. When rigging, it's about angles, forces, proper cut and direction of fall. I gave it much thought before doing the speedline because I did not want to damage my shed or my next door neightbors fence, who happens to be my boss. I set the speedline at about 55 ft.and tied the end to a nearby tree about 12 feet away. The approximate angle of the speedline was 60-70 degrees. What do you figure the added weight was. Limb was about 20-25 feet long and around 200-300 pounds. Your experience and knowledge are most welcome. |

That's a good incline angle, I take it 90 degrees is straight down and 60 degrees is between straight down and 45 degrees. You weren't bombing the pieces onto it were you?
