Photographer's Note

A chairlift (technically, an elevated passenger ropeway), is a type of aerial lift, which consists of a continuously circulating steel cable loop strung between two end terminals and usually over intermediate towers, carrying a series of chairs. They are the primary onhill transport at most ski areas (in such cases referred to as 'skilifts'), but are also found at amusement parks, various tourist attractions, and increasingly, in urban transport.

Depending on carrier size and loading efficiency, a passenger ropeway can move up 4000 people per hour, and the fastest lifts achieve operating speeds of up to 12 meters/second (27 mph, 43 km/h). The two-person double chair, which for many years was the workhorse of the ski industry, can move roughly 1200 people per hour at rope speeds of up to 2.5 m/s. The four person detachable chairlift ("high-speed quad") can transport 2400 people per hour with an average rope speed of 5 m/s. Some bi and tri cable elevated-ropeways and reversible tramways achieve much greater operating speeds. Fixed-grip lifts are usually shorter than detachable-grip lifts due to rope load; the maximum vertical rise for a fixed grip chairlift is 300-400 meters and a length of about 1200 m, while detachable quads and "six-packs" can service a vertical rise of over 600 m and a line length of 2000 m.
