摘要： This disclosure relates to an electromagnetic brake configured to slow a deceleration rate of a passenger conveyer, such as an elevator car, during braking. In particular, this disclosure relates to a passenger conveyer system including the electromagnetic brake and a corresponding method. An example system includes a controller and an electromagnetic brake. The electromagnetic brake includes a disc configured to interface with a drive shaft, a spring, and a plate biased in a first direction into engagement with the disc by a bias force of the spring. The electromagnetic brake further includes an electromagnet selectively activated in response to a command from the controller to produce a magnetic field attracting the plate in a second direction opposite the first direction to partially offset the bias force of the spring. Further, when the electromagnet is activated, the plate engages the disc.

摘要： A method for adapting an elevator system counterweight coupled to an elevator car involves: generating electric motor control commands to move the car from first to second positions in first and third test runs and from the second to first positions in second and fourth test runs, the car being loaded with a weight only in the third and fourth test runs; receiving during the car movement motor current flow measurement data and car height measurement data relative to the first and/or second positions in successive time steps in each test run; calculating at least one calibration function parameter defining a relationship between the current, the height and the weight using the current and height measurement data in the to obtain at least one calibration value; and calculating an adaptation value for adapting the counterweight to be in equilibrium with the car using the at least one calibration value.

摘要： An illustrative example embodiment of an elevator tension member monitor includes an optoelectronic detector configured to be situated near the elevator tension member. The optoelectronic detector provides an output corresponding to a profile of the elevator tension member. A processor receives the output from the optoelectronic detector and determines whether there are any anomalies in the profile of the elevator tension member. The processor reports any determined anomaly in the profile of the elevator tension member.

摘要： An elevator system includes an elevator car movable in an elevator shaft, a suspension means extending in the elevator shaft, a drive machine associated with the suspension means and a controllable coupling device arranged on the elevator car. The suspension means has a coupling element that the coupling device can be coupled to and uncoupled from, as a result of which a drive connection between the elevator car and the suspension means can be established and released. The elevator system has a guide system guiding the coupling element during a movement in the elevator shaft. The guide system has a guide that is stationary relative to the elevator shaft and a runner that is connected to the coupling element via a connection and is guided along the guide. The connection between the coupling element and the runner enables a relative movement between the runner and coupling element.

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.

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： A termination device for a suspension member of an elevator system includes a termination housing, and two wedge assemblies located in the termination housing. The wedge assemblies are interactive with a suspension member end positioned between the two wedge assemblies to apply a clamping force to the suspension member end in response to an axial load acting on the suspension member end. Each wedge assembly includes a wedge and a biasing element operably connected to the wedge to bias a position of the wedge along a suspension member axis direction.
