chair+lifts

Almost all ski/ snowboard resort has chair lifts, its a kind of pulley system with chairs that people can sit on and being lifted from the bottom of the mountain to the top of the mountain. People can sit on the chair and ride up the mountain instead of taking their skis or boards and climb it. The chair lift is just a huge simple pulley system powered my engines at the loading station at the base of the mountain. The chairs are securely attached to a thick steel cable that run along the mountain slope. More information at http://en.wikipedia.org/wiki/Chairlift
