In this way, it is ensured that a speed of the elevator car in case of a rescue situation is within a safety limit.

Disclosed is a ropeless elevator system having: a car mover operationally connected to an elevator car, the car mover configured to move along a car mover track in a hoistway lane, thereby moving the elevator car along the hoistway lane, wherein the car mover has a first tire of a first wheel that is configured to engage the car mover track when the car mover moves along the car mover track, wherein one or more of the first tire and the car mover track has an engagement feature for increasing traction between the first tire and the car mover track.

A pressurized fluid powered cabin-management system for an elevator system with a cabin and drive system is provided. The cabin-management system is configured to direct operation of the elevator system upon arrival of one of the cabins at a floor, and comprises a floor detector configured to detect when the cabin is located at a floor and to activate a timer. The timer is configured, when triggered, to activate a timing arrangement and to pass pressurized fluid to a control valve being in a first position. The timing arrangement is configured to direct the control valve to assume a second position after a predetermined amount of time. The cabin-management system performs, when pressurized fluid is passed to the control valve in its first position, actions for opening a door, and, after the control valve has assumed its second position, actions for travel of the cabin.

An apparatus comprising a counterweight, and a controller. The counterweight may comprise a frame, wheel hub motors, friction devices, weight load. The counterweight may be off its equilibrium position. The wheel hub motors may push on the guiderails/beams applying a force. The guiderails/beams front surface may tightly fit between the wheel hub motors and the friction devices wheels to (a) ensure the wheel hub motors rotate without slip. The controller may be configured to receive a signal to power the wheel hub motors and disengages the brake to (i) drive the car upwards, (ii) to drive the car downwards in response to a signal. The controller may be configured to receive a signal to stop the current flow to the motors and engages the brake to stop the car in response to a signal.

An elevator system includes an elevator car; a guide rail; and a linear synchronous reluctance motor including: a primary circuit having a plurality of primary poles and windings about the primary poles; a secondary circuit having a plurality of secondary poles; the primary circuit coupled to one of the elevator car and the guide rail, the secondary circuit coupled to the other of the elevator car and the guide rail.

A drive device of an elevator includes a frequency converter to be connected to a public AC supply network and an elevator motor. The frequency converter includes a network rectifier configured to be connected to the AC supply network, a motor bridge to be connected to the elevator motor and a DC intermediate circuit located between the network rectifier and the motor bridge. The motor bridge is controlled by a control circuit which feeds the motor bridge with control pulses to regulate the motor speed. The drive device further includes at least one drive prevention circuit connected between the control circuit and the motor bridge. The drive prevention circuit is configured to obtain a safety signal from an elevator safety circuit includes two separate safety input circuits each configured to be connected to the elevator safety circuit to receive a safety signal. Each of the safety input circuits is configured to interrupt the connection between the control circuit and the motor bridge in response to the safety signal status.

A vertical magnetic frame system 142.a, and 142.b, installed in the elevator hoist way, holding on it the entire weight of the stationary traction rope rizes 120, 124, and 126, 128, for the prefered traction system described herein, and used it to move the self-climbing elevator 100, up, or down in the elevator shaft. Further, the preferred traction system is a novelty, allowing the elevator car 100 to move up by traction gears described in FIG. 2.a, FIG. 7.a, and FIG. 10, and to move down gravitationally described in FIG. 11, and in the process to collect more than 85 percent of gravitational velocity of the descending elevator car 100, turning it ito the electricity for the building using this system
