摘要： A composite elevator belt includes at least one load carrier strand extending in a longitudinal direction, a core layer encasing the at least one load carrier strand, and a first plurality of teeth extending transversely across a top surface of the core layer. The first plurality of teeth includes a root portion associated with the core layer and a tip portion. The composite elevator belt further includes a first jacket layer extending in the longitudinal direction, at least the tip portion of the first plurality of teeth being associated with a bottom surface of the first jacket layer.

摘要： An elevator system including a cab displaceably received within an elevator shaft and a linear drive embodied to drive the cab. A sensor is disposed in the elevator shaft and a signal generation unit is disposed on the cab. The signal generation unit is embodied to generate a measurement signal in the sensor, the measurement signal depending on a displacement speed of the cab in the elevator shaft. Further, the elevator system has a safety control unit configured to ascertain an acceleration of the cab on the basis of the measurement signal and to bring the linear drive into a safety operating state should the ascertained acceleration exceed a limit value.

摘要： Elevator systems utilize safety mechanisms with brakes that engage guide rails when an elevator car limit speed is exceeded or when a free-fall condition is detected. A device may be employed in such elevator systems to simultaneously activate the safety mechanisms and vastly decrease the likelihood that failure of the members connecting one safety mechanism will render other safety mechanisms inoperative. The device may generally include a rotatable central member that is configured to be coupled to a governor assembly of an elevator system. The device may also generally include linkages that connect the central member in parallel to the safety mechanisms. When the governor assembly is activated and exerts an activation force at the central member, the central member rotates to simultaneously activate the safety mechanisms and engage brakes of the safety mechanisms with the guide rails.

摘要： A lift system includes at least one travel rail mounted in a shaft, and a lift car having a chassis that is disposed on and movable along the travel rail in a travel direction. Also mounted in the shaft is a slotted hollow conductor having a slot defined therein extending in the travel direction. A holding arrangement that holds a cabin antenna extending therefrom is further coupled to, and movable with, the lift car in the travel direction, such that the cabin antenna protrudes into an interior of the slotted hollow conductor through the slot, and is movable along the length of the slot as the car moves in the travel direction. An antenna guide extends parallel to the travel direction of the lift car and is configured to guide the cabin antenna in the slot of the slotted hollow conductor.

摘要： An elevator system includes first and second intersecting elevator shafts having respective guide devices disposed therein to guide the elevator car. The intersection area of the shafts includes a third guide device that rotates with respect to the shaft walls between alignment with the first and second elevator shafts, to permit an elevator car to transfer from one elevator shaft to the other. A safety device triggers a blocking signal in a control unit to prevent movement of the third guide device if the extent, or footprint/area, of the elevator car spatially overlaps the intersection extent defined by the area over which the third guide device can be rotated in the intersection area. A method for operating the elevator system includes triggering a blocking signal to prevent movement of the third guide device if there is an overlap between the elevator car extent and the intersection extent.

摘要： A method for operating an elevator system, include determining an expected stop extent with respect to the shaft axis of one of the two elevator cars, comparing the determined stop extent and the intersection extent of the shaft intersection with respect to the shaft axis of this elevator car, starting from a current position and in accordance with an expected braking distance of this car, and triggering a signal for one of the elevator cars.

摘要： A method can be used to operate an elevator system that comprises multiple elevator shafts, an elevator car, and a shaft changing unit. The elevator car can change from a first elevator shaft into a second elevator shaft by way of the shaft changing unit. To convey a user of the elevator system from a starting position to a destination position, a route is determined from a plurality of route options whereby initial values are taken into account for the determination of the route. In this context, a specification relating to use of the shaft changing unit is taken into account as an initial value from the initial values for the determination of the route.

摘要： A method can be used to position a car door and a landing-stop door in a synchronized manner at a landing stop in an elevator shaft of an elevator system. The car door may be configured as a guide door, and the landing-stop door may be configured as a follower door. The method may involve bringing an elevator car close to the landing stop, upon entry of the car door into an unlock zone sensing a presence signal of the follower door by way of a presence sensor of the guide door, actuating the guide-door drive by way of the guide controller and executing an opening movement of the guide door, providing movement information of the guide door, and actuating the follower-door drive of the follower door.

摘要： An elevator system with a fire protection device includes an elevator shaft having at least two adjacent shaft portions, a guide rail in the elevator shaft, a car displaceable on the guide rail, and a fire protection device having a detector, a control unit connected to the detector, and a closing element that is disposed between two mutually adjacent shaft portions of the elevator shaft and which is movable between an open and closed state to separate the two shaft portions while in the closed state. A method of operating a fire protection device for an elevator system includes detecting smoke and/or a fire via a detector, and transferring a closing element disposed in the elevator shaft from an opened state to a closed state.

摘要： A method can be utilized to operate an elevator installation comprising at least two elevator shafts, an elevator cabin, a control system, and a shaft changeover unit. With regard to the elevator cabin, the shaft changeover unit can adopt an enabled state in which entry into the shaft changeover unit is permitted and a disabled state in which entry into the shaft changeover unit is blocked. A travel route from a start position in the shaft system to a destination position in the shaft system via the shaft changeover unit is determined for the elevator cabin, whereby the elevator cabin is moved proceeding from the start position, and the control system controls a travel parameter of the elevator cabin such that the elevator cabin, proceeding from the start position, reaches the shaft changeover unit when the shaft changeover unit is in the enabled state for the elevator cabin.
