摘要： A belt for an elevator system includes one or more tension members extending along a belt length, and a jacket at least partially encapsulating the one or more tension members. The jacket defines a traction surface configured to interface with a traction sheave of the elevator system, a back surface opposite the traction surface, and two edge surfaces extending between the traction surface and the back surface. The traction surface includes a convex shaped segment extending at least partially across the traction surface between the two edge surfaces.

摘要： A method of installing an elevator system in a hoistway includes loading an elevator car with elevator system components for installation. The elevator car includes a first deck including one or more linear drive elements operably connected to a linear drive system at the hoistway and a second deck abutting the first deck, and separated from the first deck by a floor. The second deck is at least partially open at one side to allow access to the hoistway for installation of elevator system components in the hoistway. The elevator car is urged along the hoistway to an installation zone and the elevator system components are installed to the hoistway from the at least partially open second deck.
