Abstract
A guide rail () for an elevator system () includes a base () connectable with a wall of a hoistway () of the elevator system () and a web section () connected to and extending from the base (). A tip section () is located at an end of the web section () and is operably connectable to an elevator car () of the elevator system (). The base (), the web section () and the tip section () are formed of one or more thicknesses () of sheet metal material. An elevator system () includes an elevator car () located in a hoistway () and a guide rail () extending along the hoistway () and operably connected to the elevator car () for guiding the elevator car () along the hoistway (). The guide rail () is configured such that braking forces applied to the guide rail () by a braking mechanism () successfully reduce the speed of the elevator car () without resulting in failure of the guide rail ().
