Here's a couple of nutcracker sites:

The nutcracker grips the rope and the rope is attached around your waste. Once you let go your free.. Its a pretty cool concept. I'd imagine it saves alot on glove wear.

I want to know if this would be an effective way (and a cheaper alternative than using a ski lift) to haul people up a mountain in a small operation. Do you think these things would work going up a 45-degree incline?

Some ten years ago there was a proto type tow called " Mr. Ski" it used a 7 hp honda motor for power and 5/16 polyester / polypropelene rope for the haul rope . it also used a modified rescue pulley for the idler terminal , there was also some very highly machined grips that resembled pliers that were attatched to a simple harness with a small wire rope lanyard. Setting this tow up was pretty easy if you know how to do a long splice on a three strand rope. I have seen this set up with with over a thousand feet of rope out on the hill . One of the draw backs was you could only have one rider at a time on the line. It idled at 200 fpm and when the engine sensed the load it the speed ramped up to 800 fpm. About ten units were built that I know of they were only to be used in the private sector as they could not meet the ansi req. for rope twist . An optional wireless safety gate was also available bit was plaqued with many false stops.

This is great information -- thanks for sharing...I'm currently using something similar to grip 3/8" wire rope -- it looks similar only it has rubber inside the grip & clamps onto the wire -- the wire is too small to grip and too steep to really hold on -- I attached a picture for you... I still have some problems with my hand-made grip... check out my entries for rope tow -- there is some detail there....

Nutcrackers tows are cheap and easy to build. They can also go up insanely steep slopes (the Rodway Tow in Tasmania, Australia is mostly over 40 degrees), try doing that holding on with your gloves!
Instructions on how to ride a nutcracker tow from a New Zealand website.
Here is an extract from the Australian ski lift directory on WikiSki.
Rope tows (Nutcrackers). Some modern skiers who don't venture beyond the main resorts are unfamiliar with nutcracker rope tows. Most resorts in Australia and New Zealand began with nutcracker tows. While they have been replaced at the big resorts, nutcrackers can still be found at 'club fields'. Nutcracker tows are not T-bars, Pomas or platters. A nutcracker is a device attached to a belt worn by a skier that clamps onto a moving rope at waist level, allowing the skier to be towed uphill. The height of the rope and the pulleys that support it is adjusted according to snow levels. While a nutcracker may not be necessary on short, gently graded beginner tows, it is impossible for skiers to hold onto a rope with their hands on steeper tow lines or where the rope passes over a pulley.
