Abstract: An illustrative example elevator system includes a first vertical pathway, a second vertical pathway, and a transfer space situated to allow movement between the vertical pathways. An elevator car is selectively moveable along the respective vertical pathways and through the transfer space. At least one blocker has a passage condition and a blocking condition. The passage condition allows the elevator car to move from one of the vertical pathways into the transfer space when the transfer space is configured to receive the elevator car from the one of the vertical pathways. The blocking condition prevents the elevator car from moving from the one of the vertical pathways into the transfer space when the transfer space is not configured to receive the elevator car from the one of the vertical pathways.

Abstract: An elevator car is constructed and arranged to move along a hoistway. The car includes a cab support from below by a platform. A vertical member is connected to the platform via a flex joint and extends upward from platform for further elevator cab support. The flex joint facilitates cab isolation from vibration and noise.

Abstract: A suspension member for suspending and/or driving an elevator car of an elevator system includes a plurality of tension members extending along a length of the suspension member including a plurality of fibers extending along the length of the suspension member bonded into a polymer matrix. A jacket substantially retains the plurality of tension members. The suspension member is configured to be deformed at a suspension member end to allow for installation of the suspension member end into a termination assembly of the elevator system. A method of installing a suspension member of an elevator system into a termination assembly includes deforming a suspension member end and reforming it to a selected shape, inserting the suspension member end into the termination assembly and curing and/or hardening it, and applying a load thereto or to the socket or the wedge to secure the suspension member end in the termination assembly.

Abstract: A ropeless elevator system, a propulsion system, and a method for operating a ropeless propulsion system are disclosed. The ropeless elevator system may include an elevator car, a hoistway in which the elevator car travels, and a ropeless propulsion system. The ropeless propulsion system may include electrical windings energized by a power source, the electrical windings affixed to a stationary structure, the stationary structure associated with the hoistway, and a magnet, the magnet affixed to a moving structure, the moving structure associated with the elevator car, and interaction between the electrical windings and the magnet generates a thrust force on the elevator car traveling in the hoistway. The ropeless elevator system may further include an array of Hall effect sensors, the array of Hall effect sensors determining a sensed magnetic field, the sensed magnetic field being associated with electrical currents carried by the windings and used to determine a magnetic field orientation of the electrical currents carried by the windings with respect to the magnet.
