They did try it about five years ago but the Health And Safety had something to say about it
The afformentioned steepness of the lift and the fact that there was a very hard impact area underneath the run may of had something to do with it
I remember people queuing to go on it as it never stopped you had to run of it and had to be scooped up onto it (stand there and wait for contact) made it a very interesting chairlift in the day
