摘要： A belt for suspending and/or driving an elevator system component include one or more metallic cord tension elements extending along a length of the belt, and one or more non-metallic tension elements extending along a length of the belt. Each non-metallic tension element is formed from a non-metallic material. The one or more metallic cord tension elements and the one or more non-metallic tension elements are arrayed laterally across a lateral width of the belt. The belt may be used in an elevator system including a hoistway, a drive machine having a traction sheave coupled thereto, an elevator car movable within the hoistway. The belt is operably connected to the elevator car and interactive with the traction sheave to suspend and/or drive the elevator car along the hoistway.
