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.

An elevator system includes first and second elevator cars movable vertically in a first elevator shaft, a closed support belt routed around lower and upper deflection rollers, a drive machine driving the support belt, and an actuable coupling device arranged on each of the first and second elevator cars. The support belt has first and second coupling elements to and from which the coupling devices can be coupled and decoupled whereby a drive connection between the respective elevator car and the support belt can be established and released. A coupled elevator car is moved in the first elevator shaft by the support belt driven by the drive machine. The coupling elements are arranged such that they are not routed around the deflection rollers during movement of the first elevator car from a lower end position to an upper end position or vice versa.

The present invention is a kind of bulk lifting transportation system applied in buildings, which relates to the elevator technology field and the construction field. It includes a lift shaft, and the lift shaft is provided with a driving mechanism, a reversing mechanism, and its transportation belt. The driving mechanism and the reversing mechanism are respectively arranged at the two ends of the lift shaft, and the conveyor belt bypasses the reversing mechanism and is connected with the driving mechanism; The conveyor belt is provided with loading devices for placing stuff at intervals. The number of loading devices is the same as the number of floors of the building, and the distance between adjacent loading devices is equal to the distance between adjacent pick-up openings; The process of connecting and separating greatly saves the time required for single lifting transportation and can significantly improve transportation efficiency.

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.

Elevator cars are provided herein. The elevator cars include a wall panel defining part of a passenger space of the elevator car, two or more receiving rails arranged on an exterior of the wall panel, and an elevator display system having a viewing panel and an enclosure housing a display screen. The viewing panel is mounted to the wall panel on an interior of the wall panel and the enclosure is engageable with the receiving rails on the exterior of the wall panel such that the display screen is movably positioned relative to the viewing panel to be viewable from within the passenger space in an installed position.

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.
