Saw that once before, looks interesting.

Seems to me you could probably build one yourself for less than $1300.
Only tricky part would be the switch moving it from idle to tow speeds.

when you google it the patent come up.

don't mean you can't make one for personal use.

Yesterday when I did two 15 minute hikes at Jackson Hole..I thought a motor would be mad steezy yo!!!

Two tow cables. Hold them together, closes a circuit, and it switches.

no you mis understood. i mean reverse engineer from the patent. i does have this kindo cool clutch like thing.

Now your talking!

jezz only one image filed with the patent.

The invention provides a portable towing device for downhill or water skiers which includes a drive unit. This drive unit comprises a motor and a drive pulley connected to the motor by a rotor which is rotated by the motor. The motor has an actuator which is movable from an idle position wherein the motor idles to an increased power position wherein the power output of the motor is increased. A first anchor is used to anchor the drive unit in the ground in a stationary position. There is also second anchor which is engageable in the ground at a distance from the drive unit and which has a support pulley connected thereto. An endless cable extends between and is entrained about the drive pulley and the support pulley and has an upper portion and a lower portion. A switch comprising a linkage is rotatably connected to the actuator at one end and to the cable at the other end by a regulator roller. This switch is operable to move the actuator to the idle position when the tension of each of the portions of the cable on the regulator roller are equal and to move the actuator to the increased power position when the tension of the portions of the cable are unequal.

I don't get it, what is patented? Not the motor, not the rope.

 

[hardline]

wow so when you lift the cable up basically opens the throttle. and when you drop the cable it brings it back to idle pretty simple.

 

[hardline]

possibly the "switch" assembly but there would have to be a seperate filling for that as well.

That'd be a bitch in testing- imagine setting the throttle too high, and launching yourself over the crest of the hill.

Oooh- new sport- uphill ski jumping.

 

[hardline]

actually there is a guy from sweden i think that designed something like that. they used it for the iceer air comp in san fran

Love the quote at the end of the demo video on that web site -- "You get to go the same speed both ways." :-o

The land I just bought has a nice grade on part of it. Hmmmmm:idea:

 

[hardline]

when i was uvm my freinds built a tow on their parents farm just outside of town with an old cr 80

I noticed in the video there's nothing showing someone getting off the lift. I guess you lower your hands putting the engine back to idle, then disengage the cable holder. I'll bet your timing has to be pretty good on that, and I imagine a cable holder getting sucked into the pulleys would be a bad thing.

That's interesting. I'd want a beefier support system to mount that engine and pulley system to the ground though. Then again, it's not like you're hauling 20+ people at a time.
