Abstract
An elevator system includes a hoistway, an elevator car movable along the hoistway, and one or more belts operably connected to the elevator car to propel the elevator car along the hoistway. A belt of the one or more belts includes one or more tension elements extending along a belt length, and a jacket at least partially encapsulating the one or more tension elements. The jacket includes a jacket base formed from a first material and one or more insert layers embedded in the jacket base material. The one or more insert layers have a corrugated shape along the belt length, and are formed from a second material different from the first material.
