INSPECTION CONTROL SYSTEM FOR AN ELEVATOR SYSTEM AND METHOD FOR SWITCHING AN ELEVATOR SYSTEM BETWEEN A NORMAL MODE AND AN INSPECTION MODE
Inspection control system switches elevator system between normal and inspection modes and includes: operating device and at least one emergency stop switch in elevator shaft for deactivating normal and/or inspection mode, for preventing and/or interrupting movement of car. In inspection mode, car is manually controlled by operating device via electric motor, wherein elevator system is switched to normal mode or inspection mode by switch of operating device. Inspection control system also includes: detection device for detecting open and/or closed shaft door, alarm generator, operating switch for activating and/or blocking electric motor, control unit that monitors switching state and actuation sequence of switch and emergency stop switch and compares both with reference switching state and reference sequence with regard to detected state of shaft door. Alarm generator generates alarm signal and operating switch blocks electric motor if switching state deviates from reference switching state or actuation sequence deviates from reference sequence.
Blocking device
A blocking device (2) for blocking access to an door unlocking device (118) of an elevator system (102) comprises: an outer element (4), which is introducible into an access opening (30) providing access to the door unlocking device (118); and an inner element (6), which is introducible into the outer element (4). The inner element (6) is configured for bringing the blocking device (2) into a fixing configuration, in which the outer element (4) is fixedly engaged with the access opening (30), by introducing the inner element (6) into the outer element (4).
Method and apparatus for controlling an elevator system
An elevator system drive unit moves an elevator car in an elevator shaft to at least two shaft access doors under control of a control unit. The car does not move or moves only to a limited extent if an individual is in the shaft. A monitoring unit and sensor (switching contact) detect changes in state in at least one of the doors using a sequence of pulses monitoring signal. The monitoring unit has a battery and can be switched to an autonomous mode when the elevator system is entirely or partially disabled. The monitoring unit, in the autonomous mode, records state data from the sensor and is connected to a safeguard unit that reads and evaluates the recorded state data, and prevents the elevator system from being put into the normal mode of operation if a change in the state of one of the monitored doors has been detected.
LOW OVERHEAD COMPENSATORY MEASURE
An elevator car (1) comprises a working platform (4) moveable between a stowed position, at an upper part (3) of the elevator car (1), and an operational position, suspended from the upper part (3) of the elevator car (1) to be inside the elevator car (1). At least one stop (6a, 6b) is located at the upper part (3) of the elevator car (1). The at least one stop (6a, 6b) is moveable between a retracted position and a deployed position. In the deployed position, the at least one stop (6a, 6b) extends away from the upper part (3) of the elevator car (1) to provide an upper safety space (53) above the elevator car (1).
Elevator auto-positioning for validating maintenance
An elevator system is described. Aspects include an elevator shaft, an elevator car, and at least one camera, wherein the camera is operated by a controller. The controller configured to receive a maintenance request associated with the elevator system. The maintenance request is analyzed to determine an operational mode for the elevator car. The operational mode is enabled for the elevator car. The camera captures media associated with the elevator system responsive to enabling the operational mode for the elevator car.
Elevator pit safety net system
A method of operating a safety net system of an elevator system is provided. The method includes installing a sensor in an elevator pit of the elevator system and executing a learning phase of the sensor to verify successful installation of the sensor. The executing of the learning phase includes causing the sensor to sense physical characteristics of a portion of the elevator pit when the elevator pit is known to have certain physical characteristics to generate a background reading, comparing the background reading against a reading associated with known physical characteristics of the portion of the elevator pit and verifying the successful installation of the sensor based on results of the comparing.
Safety system for a service space within an elevator shaft
The invention concerns a safety arrangement of an elevator facility for safeguarding a work environment in an elevator shaft by actuating an actuator ensuring that an elevator car is not moving unintentionally during a safety situation, the elevator facility having a control system to which the safety arrangement is connected. According to the invention the safety arrangement comprises hydraulic activation means including a suspended floating platform being vertically movable, under which platform a sensing hydraulic cylinder is installed for activating the actuator upon loading of the platform.
Work area technician warning system
A method of warning a technician is provided. The method comprising: detecting a wireless signal emitted by at least one of a sensor and a user device; determining a distance between the sensor and the user device in response to the wireless signal; determining whether the user device is within a work area in response to the distance between the sensor and the user device; and conveying safety instructions through an application installed on the user device when the user device is determined to be within the work area.
SYSTEMS AND METHODS FOR DISPLAYING CABIN OPERATING PANELS IN ELEVATOR CABS BASED ON POSITIONS OF PASSENGERS
An elevator system may include an elevator car that is configured to transport a passenger between floors of a building as well as a sensor system in the elevator car that is configured to detect a passenger's location, orientation, and/or height. The elevator system may further include a touchscreen that can display a virtual car operating panel at a location on the touchscreen that is based on the location, orientation, and/or height of the passenger. The virtual car operating panel may be configured to receive input from the passenger regarding a destination floor. The touchscreen may be configured to display a virtual car operating panel for each passenger based on each passenger's location, orientation, and/or height on the elevator car.
Elevator alert system
An elevator alert system for alerting a mechanic working inside a hoistway comprises an elevator car vertically movable within a hoistway, a counterweight vertically movable within the hoistway and a compensation member with one end connected to the bottom of the elevator car and the other end connected to the bottom of the counterweight. The compensation member includes at least one light source attached to the compensation member near the elevator car or counterweight. The at least one light source longitudinally extends along the compensation member over a length.
