Engineering:GMD Müller
GMD Müller Lifts AG, known as GMD Müller, or simply GMD or Müller, was a Switzerland aerial lift manufacturing company.
GMD stands for Gerhard Müller Dietlikon.
Founded in 1947 by engineer Gerhard Müller, who is credited[by whom?] with the invention of the modern detachable chairlift in the late 1940s, it was one of the most prolific and respected aerial lift manufacturers in skiing history. The company was bought out by the management in 1985 after Müller's death and went out of business in 1992.
In the late 1920s, Gerhard Müller, a mechanical engineering student, was a newcomer to growing sport of skiing. At the time, there were no user-friendly ski lifts in Switzerland .[citation needed]
At a resort hotel outside Zürich, Müller created his first usable ski lift consisting of a 1-inch hemp rope and some old motorcycle parts. Naturally, being a rope tow, guests regularly complained about sore hands and torn clothes resulting from using the lift. The Sami people use reindeer to tow themselves around on skis, but they rest their hands by looping the reins around their hips. Inspired by this practice, Müller solved the problems of his rope tow by creating the first modern T-bar lift.[citation needed]
GMD Müller gave the licence for T-bar lift to polish company Mostostal Zabrze in 1959. Some of this lifts are still exists.[clarification needed]
During the 1960s and 1970s GMD Müller installed more than one hundred fixed-grip chairlifts in North America. Many of these lifts are still in service today. In Europe 4-seater gondola lifts with Müller's patented detachable cable grips and T-bars were more popular. Some resorts, such as Whistler, were at the time exclusively equipped with Müller lifts.[citation needed]
GMD Müller is also noted for inventing the Aerobus, a self-propelled bus-like vehicle riding on a suspended overhead cable.[citation needed]
