Abstract: A method for taking an elevator of an elevator group into service mode includes entering in the input device of the elevator group a maintenance signal which comprises an elevator definition part, upon entering of the maintenance signal the elevator identified in the elevator definition part is removed from landing call allocation, the identified elevator is initiated to serve all remaining car calls and then to drive to a maintenance floor and to wait there for maintenance operation.

Abstract: The car is connected to the counterweight with a hoisting member and further with a free fall protection member passing over at least two free fall protection pulleys provided with at least one free fall protection brake, which is controlled by a free fall protection controller. The pre-tensioning of the free fall protection member is at least 50% smaller than the pre-tensioning of the hoisting member. The free fall protection member is formed of at least one cogged belt. Each free fall protection pulley is formed of a cogged pulley mating with the cogged belt.

Abstract: A safety control device applicable to an elevator system including an elevator car driven in an elevator shaft by means of a drive device, said safety control device comprising at least one sensor configured to detect, in the elevator shaft, a presence of an object in at least one specified area of the elevator shaft, and a controller configured to receive and process a signal of the at least one sensor indicating a detection result, and to conduct, when the detection result indicates the presence of an object in the at least one specified area of the elevator shaft, a safety procedure in which a switch from a normal drive control of the drive unit to a safety drive control is executed in which a target value set for the speed of the elevator car is decreased.

Abstract: Elevator safety and safety related information needs to be sent reliably to safety controlling systems. Existing elevator communication devices may be used for transmitting this information by processing the received safety and safety related information and processing it before sending it over the communication bus from the elevator car or floor equipment to the controlling devices. A separate communication unit may be used for receiving and processing safety and safety related data packets before they are transmitted over a common bus used for safety and safety non-critical submission.

Abstract: A method includes calculating a motor torque estimate for an electric motor of an elevator in an elevator run, determining a difference between the calculated motor torque estimate and a realized motor torque during the elevator run, and generating a signal indicating possible brake dragging based on the difference between the motor torque estimate and the realized motor torque.

Abstract: An elevator rescue system allows an elevator car of an elevator to be moved in an emergency situation. The elevator includes an elevator motor acting on hoisting ropes by which the elevator car is suspended including at least one electro-mechanical brake and an encoder outputting a signal corresponding to its speed. The rescue system includes a back-up power source, a jerk monitoring circuit connected to the encoder and including a memory storing an upper threshold value for the derivative of car acceleration, a brake feed circuit controlled by the jerk monitoring circuit, and a release switch connected to the jerk monitoring circuit and/or to the brake feed circuit. The release switch activates the brake feed circuit to release the brake, and initiate the jerk monitoring circuit to compare the derivative of car acceleration derived from the encoder signal with the stored first upper threshold value, and forwards a control signal to the brake feed circuit to initiate/stop braking depending on the comparison result.

Abstract: A method for controlling an elevator includes controlling the speed of a vertically moving elevator car during its run from a starting landing to a destination landing according to speed settings, the speed settings defining a constant target speed for the elevator car. The method includes obtaining measurement data of the ongoing run, which measurement data describes vertical speed and/or vertical acceleration of the vertically moving elevator car, determining whether the measurement data meets one or more predetermined criteria indicating unintended vertical speed and/or unintended vertical acceleration, and changing the speed settings of the current run by lowering the constant target speed from a first constant target speed to a second constant target speed if the measurement data meets said one or more predetermined criteria, continuing the run without intermediate stops to said destination landing. An elevator is provided to implement the method.

Abstract: The elevator comprising a car moving upwards and downwards in a well, a controller controlling the elevator, and a well lighting. The method comprises detecting an activation of a well access operation mode of the elevator, activating the well lighting automatically when the controller detects that the well access operation mode of the elevator has been activated.
