An elevator includes a hoistway; an elevator car vertically movable in the hoistway, the passage to and/or from the elevator car being provided in depth direction of the hoistway; a counterweight vertically movable in the hoistway beside the elevator car in width direction of the hoistway; one or more ropes interconnecting the elevator car and the counterweight and hanging from these; a rope wheel arrangement in the bottom end of the hoistway for guiding the one or more ropes; and a vertically oriented guide rail for guiding the elevator car extending between the elevator car and counterweight. The elevator includes a bridge structure mounted on the floor of the hoistway, the bridge structure including a cross member, wherein the guide rail for guiding the elevator car is mounted on top of the cross member, the bridge structure including a passage for the one or more ropes below the cross member, and the one or more ropes pass from the counterweight downwards to the rope wheel arrangement, and the rope wheel arrangement is arranged to guide the one or more ropes to pass below the cross member via said passage and up to the elevator car.

A transfer station (40) for a ropeless elevator system hoistway (11) is provided. The transfer station (40) includes a first lane (13, 15, 17), a second lane (13, 15, 17), and a parking area (42) located proximate one of the first lane (13, 15, 17) and the second lane (13, 15, 17). The transfer station (40) also includes a plurality of carriages (46) moveable within the first lane (13, 15, 17), the second lane (13, 15, 17), and the parking area (42), the plurality of carriages (46) configured to support and move an elevator car (14). The transfer station (40) further includes a cassette (44) configured to support and move the plurality of carriages (46). The transfer station (40) yet further includes a guiding member (48) engaged with the cassette (44), wherein the position of each of the plurality of carriages (46) relative to the first lane (13, 15, 17), the second lane (13, 15, 17) and the parking area (42) is modified by horizontal or vertical movement of the cassette (44).

A method for centering a self-propelled elevator car in an elevator installation, the car having at least two driven friction wheels pressed against each of two opposing guide surfaces of a first and second guide rail strands to drive the car along a travel path, the method including independently adjusting a first rotational speed of the friction wheels acting on the first guide rail strand and a second rotational speed of the friction wheels acting on the second guide rail strand. In a centered state, a center of the car is located on a center plane extending in parallel with the first and second guide rail strands, and when a deviation of the car center from the center plane is detected, the first rotational speed and/or the second rotational speed is changed such that, when the car moves along the travel path, the car center moves toward the center plane.

Embodiments herein are directed to an electrical assembly for grounding an elevator assembly, the elevator assembly having an elevator cab, a grounded elevator frame, a sheave, and a suspension member having conductive members and a sleeve enclosing the conductive members. The suspension member extends around the sheave to support the elevator cab. The electrical assembly includes a bracket and a grounding member. The grounding member is electrically coupled to the sheave such that contact with the sheave forms an electrical ground path between the sheave through the grounding member and the bracket, and into the grounded elevator frame. When the sheave rotates the suspension member, any portion of the conductive members from the suspension member making contact with the sheave grounds the sheave to the grounded elevator frame via the electrical ground path.

A mounting frame for being displaced and fixed in a shaft has a main frame, a first primary fixing component for supporting the mounting frame on a first shaft wall of the shaft and a secondary fixing component for supporting the mounting frame on a second shaft wall of the shaft opposite the first shaft wall in a fixing direction during fixing of the mounting frame in the shaft. The first primary fixing component and the secondary fixing component are arranged on the main frame. The first primary fixing component and/or the main frame can assume a transport position and a working position. A change of the first primary fixing component and/or the main frame from its working position to its transport position leads to a reduction in an extension of the mounting frame in an extension direction that differs from the fixing direction.

An elevator system wherein a cab is moved within a shaft by a tractive drive system that transmits torque frictional force on the interior surface of the shaft, enabling the cab to travel without cables and travel for long distances. The tractive drive system automatically regulates these normal forces. A method of controlling a plurality of these cabs disposed within a plurality of shafts by means of electronic systems.

An access door arrangement of an elevator shaft, wherein at least one elevator car is moving, includes a door lock, whereby in connection with the door lock a reset switch of an inspection mode resetting device is located, whereby the door lock has a lock part movable between a lock position and an open position and whereby the reset switch is integrated in said door lock to be operated by the movement of the movable lock part or a related movable part. This solution allows an easy resetting of the inspection mode of the elevator.

Disclosed is an elevator system for a multi-level architectural structure, the elevator system having an elevator controller for an elevator in a hoistway, wherein the elevator controller effects a first determination of whether passengers or goods are in the elevator and effects a power mode for the elevator based on the first determination.

A method and a system for the evacuation of buildings providing an elevator system includes at least one elevator car and an elevator shaft. The system includes a device to detect an incident or a device to receive an emergency signal in this regard, a device for determining the floor of this incident, and at least one sealing element (positioned in the elevator shaft and constructed to seal the elevator shaft, so that the elevator shaft is divided in at least two sections.

Disclosed is an elevator system having a first sensor in communication with an elevator in a multi-level hoistway, wherein during an emergency the elevator instructs the first sensor to sense conditions and transmit sensor data representing the sensed conditions, and the transmitted sensor data is processed to obtain an image representing an intensity of hazard conditions on at least a subset of levels serviced by the multilevel hoistway.
