摘要： An illustrative example elevator assembly includes a header beam and a first elevator cab supported by the header beam. A plurality of vertically oriented rods extend beneath the first elevator cab. A horizontally oriented mid-beam is coupled to a first one of the rods near a first end of the mid-beam and coupled to a second one of the rods near a second end of the mid-beam. A second elevator cab is situated beneath the first elevator cab and beneath the mid-beam. At least one linear actuator is supported at least partially on the mid-beam. The linear actuator selectively causes vertical movement of the second elevator cab relative to the rods.

摘要： A termination device for a suspension member of an elevator system includes a housing and a wedge located in the housing. The wedge extends across a width of the suspension member and at least partially across a thickness of the suspension member. The wedge is interactive with the suspension member to apply a clamping force to the suspension member in response to an axial load acting on the suspension member. The wedge includes a wedge lip configured to contain the suspension member within a lateral extent of the wedge.

摘要： A zone object detection system including a passenger compartment. Also included is a door moveable between an opened position and a closed position. Further included is a first sensor monitoring a first zone outside of a plane of the door. Yet further included is a second sensor monitoring a second zone comprising at least one of the plane of the door and outside of the plane of the door. Also included is a controller in operative communication with the first sensor and the second sensor, the controller commanding a first modification of a door closing movement of the door if an object is detected in the first zone, the controller commanding a second modification of the door closing movement of the door if an object is detected in the second zone.

摘要： A multi-car ropeless elevator system includes at least one lane. An elevator car is arranged in the at least one lane. A linear motor system includes a plurality of stationary motor primary sections extending along the at least one lane and at least one moveable motor secondary section mounted to the elevator car. A plurality of sensors is operatively connected to the linear motor system. Each of the plurality of sensors is operatively associated with a corresponding one of the plurality of stationary motor primary sections. A sensor failure detection and fusion system is operatively connected to each of the plurality of sensors. The sensor failure detection and fusion system operates to identify failures in one or more of the plurality of sensors and fuse data received from remaining ones of the plurality of sensors.

摘要： An illustrative example elevator assembly includes a first elevator cab and a second elevator cab. An H frame supports the first elevator cab and the second elevator cab. The H frame has a plurality of vertically oriented beams and at least one horizontally oriented beam extending between the vertically oriented beams. The at least one horizontally oriented beam is spaced from ends of the vertically oriented beams and the H frame does not have any horizontally oriented beam at either end of the vertically oriented beams. At least one linear actuator is coupled with the first elevator cab and the second elevator cab. The linear actuator is configured to selectively cause movement of the elevator cabs relative to the H frame.

摘要： Disclosed is a system for an elevator door of an elevator car, wherein a controller controls the elevator door to travel in a proximate direction when closing and travel in a distal direction when opening, the system including: a panel that forms an exterior surface of an elevator door, the panel including a front surface extending in a widthwise direction between a proximate end and an opposing distal end to form a front surface of the elevator door, the panel including a proximate end surface extending in a depthwise direction to form a proximate end surface of the elevator door, the proximate end surface of the panel comprising a resilient portion that is capable of engaging a sensor in the panel when the elevator door is closing, and thereafter the controller instructs the elevator door to reopen.

摘要： An elevator door control system, an elevator system, and an elevator door control method based on to-be-carried object grouping identification. The elevator door control system includes one or more three-dimensional sensors, arranged to capture three-dimensional data of to-be-carried objects in an elevator waiting region, wherein the three-dimensional data includes depth data; a data processing device, communicating with the three-dimensional sensor, and configured to receive and process the three-dimensional data, to provide grouping data of one or more groups obtained according to correlations between the to-be-carried objects and position data of each to-be-carried object in the elevator waiting region; and a control device, connected to an elevator door, communicating with the data processing device, and configured to control operation of the elevator door according to the grouping data and the position data.

摘要： An illustrative example elevator system includes a frame, a first elevator cab, a second elevator cab, and a plurality of sheaves associated with the first and second elevator cabs, respectively. A suspension assembly suspends the first and second elevator cabs within the frame. The suspension assembly has two ends in a fixed position relative to the frame. The suspension assembly includes a positive drive load bearing member along a first portion of a length of the suspension assembly and at least one other second load bearing member. A machine includes a drive sprocket that moves the positive drive load bearing member to cause movement of the first and second elevator cabs relative to the frame.
