Abstract: Depth cameras may be placed within an elevator car hoistway to capture depth images of the elevator rope. 3D sensing software may be used to identify the rope within the depth images and assign tracking points to locations along the rope. Tracked images are saved over time and compared to prior tracked images to determine the movement of tracked points between images. Movement of tracked points may be used to determine the velocity, acceleration, frequency of wave motion, and other characteristics of the rope during a period of time. When measured characteristics exceed specified thresholds, the system may take one or more actions to mitigate the undesirable behavior or provide notification of the undesirable behavior.

Abstract: An end termination clamp for a tension member includes a linkage configured for connection to a structural element and a first plate opposite a second plate defining a space therebetween to accept the tension member. Each of the first and second plates have a linkage end connected to the linkage, a belt entrance end, and a main body extending between the linkage and belt entrance ends.

Abstract: An elevator arrangement includes two or more hoistways, at least one more elevator car than a total number of hoistways, and at least one more belt system than the total number of hoistways. At least one belt system may be provided between each pair of hoistways. At least one elevator car may be provided in each hoistway. Each elevator car may be connected to at least one belt system. The belt systems may provide a direct transfer of mechanical energy between the elevator cars. As a first elevator car moves downward in a first hoistway, mechanical energy may be generated via the belt systems to lift a second elevator car upwardly in a second hoistway.
