Rope Winch

[rbtree]

and the roll around the middle? What's up with that?.... The wife's good cooking, Graeme? or lack of a good valet to dress ya...?


What about your address, big guy?


http://www.tufftug.com --is a bit bigger unit that costs $4200 Cdn...

Tom and Roger

My wife is holding the winch, I took the picture. She is saying some very uncomplimetary things about you, advise you do not visit Australia for some time.

 

[rbtree]

oh boy...


"hell hath no fury like a woman scorned..." especially on with such rippling muskles...


am i ever in trubble!

Um, anyone know if Icelnd accepts people on the run?

I s'pose acceptance of apologies will be out of the realm of possibility.....

Maybe if you ship a few iced salmon down there....

Scotty?

Graeme
This is the Tassie version of a scotty.yours looks interesting though.

are you trying to upset him too.
Salmon is a banned import( some thing to do with fish diseases)
He'd have the quarantine guys swarming all over his property.

rope winching

Rob- I've been looking at the photo you posted.I don't understand how the "Tasmanian" Scotty rope winch works. It appears as though the chainsaw is touching the rope. Is this just suicide or can you actually ascend the rope using the saw teeth?! I'd be wary of such dangerous sharpe ways of experimenting with your lifeline. Is it some kind of joke?



Alternatively, a friend of mine in Cairns, Queensland, told me about tying one end of the rope to the car and having the girlfriend drive down the road- and he was up the tree with no effort. (And indeed, no way to get down on his own). Similar concept to automatic winchings. :

Seriously though can you tell us more about the little winch?
Brand name ,where from,price,applications?...Thanks mate

Yoav

...LOL... I heard of a guy who ( urban myth?) who tied his line to the tow bar of his car so he could work on the back of his roof. He neglected to tell his wife who came out of the house , hopped in the car and drove off...
Anyway ..how are you going with the project. This might be the forum to ask about that list...
Be careful though I dont know they react to tree scientists

 

[Graeme]

Have got specs here - sorry about the delay, missed the post.

...and here is the other half...

i believe this is a pic of 'beam me up Scotty'

Nice to hear from you again Graeme,
All Aussie's welcome!

Using the winch to access past very large sheets of loose hanging bark on a dead mature E. regnans. In this situation, the winch comes into its own because there is no bouncing effect created on the rope whilst ascending and the climber can focus on the hazards of dead wood above.

[Graeme]

After using explosives to blow the limb off (I was nowhere near the tree when we let it rip ), the winch was used to access back up the tree and past the hanging limb. Again, the climber can focus on th hazards of the situation whilst ascending. Here the winch is being lowered down once the high point is gained.
Anyway, got some video and more photos of the winch in action on that job if interested.

Here's a rope capstan winch mounted on a bucket truck. This 900 # capacity upper boom hydraulic winch is on a 55' Teco 4X4 truck with 4 outriggers. It also has major winches mounted in the front & rear bumpers, and will go just about anywhere. Notice the extendable jib that can be rotated around quite a range. We used the capstan as an aerial lowering device to piece down a storm-busted willow over a house in Ashland, Oregon last week.

By the way, John Kakouris has this truck for hire in northern California/southern Oregon, for those of you in the neighborhood.

i thought a rope capstan didn't collect line, so maintained leverage as spool diameter was the same, but could have endless travel with endless line? Whereby you had to maintain pull on control end to make it grab rotating drum.

Could such a winch be used for no shock lifting, then used for lifting a man; seeing as you could change the line? Would/is that an exception to not mixing rigging/climbing gear as any overload (non-shock) would make the line slip on the drum, acting as a mechanical fuse, limiting force to capstan system and anchoring?

 

[Oxman]

Either, depending on the capacity of the spool, and amount of power available. In the case of the hydraulic winch, I don't spose all available power is needed for the load.

As far as the 'exception', I assume this means an arbitrary rule confining use of a lifeline to personal support only. I use my climbing lines interchangebly as lowering lines. A rope is a rope, to me. The one in better condition is usually designated the climbing line.

The only time I've seen climbers getting power-lifted (aside from riding the hook of a crane) was in a palm tree. It was a short Washingtonia robusta (Mexican {skinny} Fan Palm). There was a row of these neglected palms in an overgrown English Ivy bed at a motel that had skirts to the ground. The palms were closely spaced, so that it was easier to hop from treetop to treetop rather than work up from the bottom of each one.

The climber came down for lunch and left his rope crotched in. Upon returning, he hooked up and tied the tail of his climbing line to the pickup truck bumper. As he motioned for the driver to creep away, the rope bound up in the leaf bracts and bent the trunk over quite a ways before it started to slide, allowing the trunk to pop upright. It repeatedly 'chattered' sideways & upwards during the ascent, and it looked like the tree could have broken off under the binding.

Use of a pickup for pulling in this application leaves out the sensitivity necessary for the driver to notice when to back off. Using the rope taxi may allow this enhanced control. The MAD ascender (Motorized Ascending Device) was an earlier version from 1971.

i understood the 'beam me up Scotty' line of Oddese, to refer to human cargo?

i think that all discaimers abide, especially when talking less care/division for safety gear. Of course i go right to the image of 1 ol'boy around here (actually climbed tied in 1st with him); that will climb, rig, descend, tie down load with line dragging on road as he drives off, pull off load (sometimes breaking line, that is hardly ever a recognized specialty line), store around gas under saw sometimes in weather his only line, that he throws in the truck with gas, oil the next day to climb on!! "Flew" him to emergeny once myself, another time i was the one to get his dad; as that thump on the ground seemed harder at the time!

So i stick to the rule of seperation of rigging and climbing gear, as simple enough for me, tieing in 2x when cutting as failsafe strategy, carting a guy off that started you on safety gear is kinda sobering as you remeber it hanging from a frail 1/2" line!! i think OxMan has to make carefull choices because of the scale he works on and still being here to speak, and view that level as an extreme. i think most anyone else should go with a 'religious' seperation of these categories, only perhaps cheating, maybe a few times in years; when you really understand what chances/choices are being made on a large scale.

MAD endless line device looks great! i can imagine in backyard holding a load high in a tree, and MAD drawing load over garden/house/pool in the shortest (literally as bird flys), no labor path to truck. Rather than smaller pieces rigged down, dragged 6x further through obstacles, land mines (doggy doo). Think it would work for line tension/lift, then lower through locked out sheaves to work as polished friction brake?

Another advantage of the access winch I have been using is that after the high point is achieved the winch can be anchored to the trunk and utilized to haul up heavy ropes chainsaws and other equipment. This can be done precisly to the climbers discreation and over the distance to the ground crew reduces communication requirments. I do prefer a rated peice of equipment that is not to say I do not enjoy experimentation Not withstanding this I still run a seperate safty from my harness to an acender on the rope, above the winch. Why put all your eggs in one basket?

bump

So how much would you guys think a personal lifting device like this would be worth????

What would you pay?
