Personal Ski Lift PSL

post #1 of 18
Thread Starter 

Hello, riders.

 

Have something to share with you. It might be interesting for some of you.

We are currently trying to release some useful feature on our opinion and ask you help us to see the weaknesses of this device.

 

So, we have this device:

Personal Ski Lift PSL Lifting is carried out on a stationary climbing cord, which needs to be fixed from the beginning at the highest rise’s point. The PERSONAL SKI LIFT is attached to a carabineer strap, which puts rider. Point of force application is in the area of the abdomen. After the lifting device is removed in a backpack. Product Specification: The maximum weight of the device (including batteries) = 12 pounds (5 kg). Maximum weight lifted load = 330 pounds (150 kg). Maximum speed: - Vertically = 2 miles/hour (3 km/h); - At an angle of 45 deg rise. = 4 miles/hour (6 km/h). Battery capacity: 5800mAh. Engine power = 2700W (RPM/V: 245kv).

Hi Alex, it appears that to use this, one would climb the slope attach one end of the device to the top, descend with cable and motor (not skiing, just getting down) then hook-up and ascend, detatch and get a good run in...

 

The problem I see is: I climbed the slope, attached the end of the cable to the top, then after descending, used the device to ascend, I got in a good ski run... but I didn't get 'extra' skiing, I climbed up, got back to the bottom, used the device to get back up then skied a run. Why no just climb up without the weight of the device and ski back down???

Hello, Whiteroom. Thanks for your feedback.

Цe assume that a man rises to the top and fixs the cord using trees and stones. The group may connect to the cord from the bottom and start to get to the top. At the top of the device hidden in a backpack and go down. Well suited for the group.
Advantage in time and maintaining power for running ... it is estimated that when we went on Elbrus, the day made up of three lifts, slopes ... and rising forces remained at the end of the descent ... immediately easy climb and much shorter for time .....

For better understanding you may watch following video:

You can mount device in top point, and roller in bottom point and use circularity rope(no need to pulling the rope), but the height difference will be not much. 

When you use device with stationary rope, u can mount several ropes about 200-300 m lenght each. And height difference will be about 1 km(if u will take 2 accums). 6 kg on your back is not so heavy)

If I wanted lift assisted skiing I wouldn't be in the backcountry :dunno

some people don`t want use energy for climbing, they want just ride)

It seems to me that this device would have applications in mountain rescue/recovery by making it easier to move a victim up steep hills.

post #8 of 18

Pretty cool.   How many meters of cord (rope) can you climb before the battery needs to recharge?   Can you change/swap the battery with a fresh one?   How long does it take to charge?

 

I'll speculate the answers to those questions might lead you in another direction, a good old internal combustion engine.   With an engine from, say, a chainsaw you could keep going all day!

The problem I see is having to carry the rope up the hill to attach it to something. A good solution would be something like a bow and arrow to shoot the line up and attach it to a tree. Or maybe even a crossbow? That way you wouldn't have to climb at all.

If you use my idea please PM me for information on how to include me in the profit-sharing.

I like it, not for back country skiing excursions, and not for mountain biking.  I bike for exercise and biking uphill is very good exercise.  It  would be good for back yard skiing or a local hill to get some powder turns on.  You could leave your ropes fixed in place an use your personal lift.  

 

Not a personal criticism, but you should put together a more professionally shot video.  Also shoot it in the hills this winter so you can show skiers in the snow.  Wouldn't hurt to have a snow boarder in there as well.  Everyone knows they are lazy (kidding)

1 battery can lift about 80 kg in 400-500 m vertical - energy calculation (diferent angle of slope cause different energy losses by friction, etc. The more angle of slope- more high different) 

post #13 of 18

Boob Lee, if you invent perfect crossbow to deliver the rope top of the hill with fixed there, welcome)) It will be, perhaps, the more better inventing than owr personal lift))

Hi all.

Here is the new test of Booster PRO Ski.

Please, have a look and let us know your opinion.

This thing is awesome, maybe its just the engineer in me coming out…  I completely agree with crank as far as application of the device goes. I personally wouldn't use it as a substitute for exercise, sometimes it's nice to just go out and earn some turns. Where I see this being useful is skiing on private land or somewhere deep in the BC/somewhat hidden where people won't get bent out of shape about it. Do some grunt work in the summer and set up the lines. The good thing is you can set up the lines responsibly (with tree savers and such) so you aren't impacting the forest at all, that will definitely sit well with some people. Sounds like you could even have multiple lines to get up something pretty significant. 

 

 

 

Short version of what I'm trying to say VVV

My only gripe would be skiing down with a >12lb pack. I think it would be a HUGE turn on to have some sort of attachment that could be flipped out that would provide some sort of breaking mechanism, meaning you could clip it back onto the rope and have it lower itself down. Now if you had multiple lines going up you'd have to have one long line going down for lowering. 

 

Just spitballing here, but there are two methods that come to mind for said breaking mechanism. 

1.) Friction (much like an ATC belay device for climbers, where the angle of the tag end of the rope has an effect on the amount of applied friction)

2.) Using the electric motor to provide engine breaking

 

IMO it would be much easier to design an adjustable friction device. That way you can tune it in for different slope angles.

 

This is an example of what I'm talking about, however for PSL it would need to be fully adjustable. IE like a bicycle chain tensioner.

Nice video.  I guess I should stop complaining about the snow around here.  Wow, those are some sketchy conditions!   :)

Eoy!:) Best ski video with personal lift)
