Product Description
An elevated passenger ropeway, or chairlift, 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 m/s (26.8 mph; 43.2 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 (8.2 ft/s). The four person detachable chairlift ("high-speed quad") can transport 2400 people per hour with an average rope speed of 5 m/s (16.4 ft/s). Some bi and tri cable elevated-ropeways and reversible tramways achieve much greater operating speeds. ... Read more

High Quality Content by WIKIPEDIA articles! Heliskiing is off-trail, downhill skiing that is accessed by a helicopter, not a ski lift. Heliskiing is essentially about skiing in a natural albeit highly selected environment without the effort or gear compromise required for hiking into these areas as in ski touring or ski mountaineering. Most heliskiers are seeking specific, pleasurable skiing conditions that are hard to replicate in the highly manipulated terrain of ski resorts: particularly powder snow, but also long descents, natural terrain contours and features, smooth corn snow, old-growth tree glades, steep and extreme slopes, or for the more adventuresome, wild snow and a natural, variable environment. The presence of the guide and machine offer some protection against the risks and discomforts unavoidably associated with entering this mountainous environment, allowing skiers with little or no mountain sense to enjoy a wild environment. ...
