A running system for an elevator comprises a car, running rails, and a driving mechanism, the car is moved on the running rails by means of the driving mechanism, and the running system does not comprise a traction part. In a multi-car elevator running system; the running system is provided with a plurality of cars and at least two set of running rails, and each set of running rails can be used for the movement of the cars; the running system is further provided with at least one switching mechanism and driving mechanism, the car is moved on the running rails by means of the driving mechanism, different running rails are connected by means of the switching mechanism, and the car is switched to the different running rails by means of the switching mechanism.

A stair lift eliminates a hindrance to the normal use of a staircase. The stair lift comprises two rails disposed along the staircase in parallel to the width of the staircase, a self-propelled gantry-shape carriage having a gantry-shaped structure, traveling on the rails with a restriction to prevent a derailment, and a lift step (1) disposed between left and right leg structures of the gantry-shape carriage and supported by a lifting mechanism provided in the leg structure. When the gantry-shape carriage stands by at a lower floor or a upper floor of the staircase, the lift step (1) lands on the floor adjacent to the staircase or a step of the staircase, and when the gantry-shape carriage travels on the rails, the lift step is held at a position preventing an interference with steps of the staircase. A user gets on the lift step (1) while standing.

An overspeed safety braking mechanism for lift cars and elevator systems is described herein. The safety mechanism may comprise a safety kit secured to an overhead portion of a lift car, and configured to engage a cable to prevent a downward movement of the lift car. Engagement of the cable may occur when a threshold speed is reached. The overhead portion of the lift car is detachable upon a predetermined upward force resulting from an engagement of the safety cable from the safety kit. A primary brake system may be positioned beneath the safety kit, on or near a lift platform, configured to engage the safety cable in response to an activation of the safety kit and a detection of the threshold speed.

The system comprises a synchronization shaft rotatably supported on an elevator car frame, the synchronization shaft being operatively connected to at least one safety gear, a lever attached to the synchronization shaft, an electromagnet operatively connected to the lever, spring means operatively connected to the synchronization shaft, and resetting means operatively connected to the synchronization shaft. Deactivation of the electromagnet releases the lever allowing the spring means to rotate the synchronization shaft from a first position to a second position in which the safety gear is activated. Activation of the resetting means rotates the synchronization shaft from the second position to the first position in which the safety gear is deactivated and the spring means is brought back to the excited state at the same time.
