Abstract: An elevator system includes a hoistway (217) including a landing (225A-225C), which includes a landing door (227A-227C), an elevator car (203), comprising an elevator car door (229), arranged to move within the hoistway (217), a first safety switch (231; 233) configured to indicate a potential hazard in the elevator system (201) and a controller (215). The controller (215) is configured, when the first safety switch (231; 233) is triggered, to stop movement of the elevator car (203) and determine whether the elevator car (203) is located anywhere within an unlocking zone (253) in the hoistway. The controller is further configured, if it is determined that the elevator car (203) is located anywhere in the unlocking zone (253), to allow the elevator car door (229) and landing door (227A-227C) to be opened.

Abstract: During a maintenance inspection, an optical rope diameter measuring device is provided at a predetermined position along a path of a wire rope, rope diameter is measured at multiple measuring points while the elevator is driven in test mode, and diameter reduction at each measuring point is determined and stored as a first diameter reduction (S2_S6). During a subsequent maintenance inspection, rope diameter is similarly measured at each measuring point to determine diameter reduction constituting a second diameter reduction (S7_S11). Based on these two diameter reductions, the time at which diameter reduction will reach a predetermined threshold value is predicted for each measuring point, and the earliest time is displayed as a rope replacement time (S12_S14).

Abstract: An elevator car comprises one or more side walls (4a) defining an interior space for accommodating passengers and/or cargo, and a support frame positioned above the interior space. A working platform (12) is suspendably connected to the support frame and moveable between a stowed position, above the interior space, and an operational position, suspended within the interior space. The working platform (12) comprises at least one stabilizing member (14) and the at least one stabilizing member (14) comprises a first engagement portion (22). At least one side wall (4a) comprises a second engagement portion (6) such as a handrail. When the working platform (12) is in the operational position, the first engagement portion (22) is configured to engage with the second engagement portion (6) so as to stabilize the working platform (12) in the operational position.

Abstract: The present invention relates to the determination of the movement of a passenger relative to an elevator car and belongs to the field of elevator intelligent control technologies. The present invention acquires information about the movement of a passenger relative to an elevator car, wherein the information about the movement of the passenger relative to the elevator car is determined based on a change in the signal strength of a first wireless signal received by a personal mobile terminal carried by the passenger and a change in first floor information and/or traveling direction information.
