The history of the company begins in 1926, when Jakob Wyssen, barely 20 years old, starts to operate a sawmill on his own. It was his pioneering spirit that led him to revolutionize the way logs were brought out of the forest, namely at breakneck speed with a lot of damage to the raw material and the forest floor (see film). He invented the cable crane – a material cableway that can lift and carry away loads at any point along its cable line. As early as the early 1940s, he began to mass-produce rope winches and trolleys for rope cranes. The quality and durability of Wyssen rope crane systems still set the standard today and are in use in over 60 countries worldwide. Wyssen is also a pioneer in the field of avalanche safety. In 1974, one of the first bomb tramways were installed by Wyssen at the Weissfluhjoch in Davos.
