An elevator system includes an elevator car for travel in a hoistway; a stator positioned along the hoistway; and a magnetic screw assembly coupled to the car, the magnetic screw assembly coacting with the stator to impart motion to the elevator car; the stator including a service section having a plurality of poles to coact with the magnetic screw assembly; the stator including a transfer station section, the transfer station section of the stator including a plurality of stator permanent magnets.

An elevator that incorporates a framework that allows multiple autonomous mobile lifts to move independently inside and outside a building or a group of buildings in shafts and corridors in such a way that multiple lifts can share a shaft and/or corridor.

An elevator system includes a first elevator car (28) constructed and arranged to move in a first lane (30, 32, 34) and a first propulsion system (40) constructed and arranged to propel the first elevator. An electronic processor of the elevator system is configured to selectively control power delivered to the first propulsion system (40). The electronic processor includes a software-based power estimator configured to receive a first weight signal and a nm trajectory signal for calculating a power estimate and comparing the power estimate to a maximum power allowance. The electronic processor is configured to output an automated command signal if the power estimate exceeds the maximum power allowance.

An elevating cage apparatus includes a support structure and a carriage that is operable to move vertically with respect to the support structure. The carriage is configured to be alternatively raised and lowered via a first driver and a second driver. The first driver may comprise a powered (electric, hydraulic, or pneumatic) motor, and the second driver may comprise a manual actuation mechanism including a hand crank. Both input drivers may be operable to move the carriage through a dual input worm drive gear box.

A lifting assembly, a jump elevator and a jumping method. Wherein the lifting assembly comprises: a supporting platform provided with a plurality of telescopic first pawls at the side face thereof; at least one screw mechanism comprising a screw and a sleeve, the screw and the sleeve each being provided with an external thread and an internal thread matching with each other; and a driving mechanism configured to drive one of the screw and the sleeve to rotate in relative to the other, such that the screw mechanism extends or retracts; wherein the screw mechanism is connected between the supporting platform and the operating platform, one of the screw and the sleeve is configured to be rotatably attached to one of the supporting platform or the operating platform.
