Prestigious references around the world


SIGMA was founded in 1961. Three years later, the company designed and built the famous "egg" which integrated revolutionary automatic doors. 

SIGMA was very quick to set the pace in the market for ropeway carriers. It is recognized for its innovative concepts and wide range for both new installations and renovations. Just like POMA, SIGMA's priority is ensuring optimal comfort for all passengers.

From New York to Vancouver, Cairo to London, in ski areas all over the world, SIGMA designs customized cabins for urban mobility and summer and winter tourism.
