Abstract: A method for inspecting a condition of an elongated load bearing member of a rope of a hoisting apparatus, such as an elevator includes ultrasound scanning one or more regions of the load bearing member with an ultrasonic scanner. A method for inspecting a condition of a rope of a hoisting apparatus, such as an elevator, which rope includes at least one load bearing member includes inspecting at least one load bearing member of the rope with an ultrasound scanner.

Abstract: In the technical field of elevator systems, so as to provide a measure for preventing an overspeed governor rope inertia from unwantedly engaging a safety gear in an overspeed governor system, which has a governor rope connected to a moving mass of the elevator system, a machinery brake for decelerating the moving mass so as to perform a quick stop of the moving mass, a safety gear mounted to the moving mass, a synchronization linkage for tripping the safety gear and a synchronization linkage blocking device for blocking the synchronization linkage and/or a governor brake for braking the governor rope, it is determined whether a quick stop of the moving mass is performed, and the governor brake or the synchronization linkage blocking device is activated when the quick stop of the moving mass is performed.

Abstract: A method for controlling movement of an elevator car includes driving the car vertically to a landing; activating a park brake; and holding the car immovable with the park brake. The holding includes compressing a guide rail by compression members with a first compression force; opening a door for allowing loading and/or unloading the car; maintaining the door open for allowing loading and/or unloading the car while the car is held immovable; and starting closing movement of the door. After the starting closing movement of the door, relieving the brake for allowing the elevator car to start to move vertically. The relieving includes reducing the compression force of the brake, to be smaller than the first compression force, such that the compression members start sliding vertically against the guide rail; maintaining compression with a smaller compression force than the first compression force, allowing the compression members to continue to slide vertically against the guide rail; and thereafter removing the compression.

Abstract: An elevator including a hoistway, an elevator car vertically movable in the hoistway, a rope connected to the elevator car movably together with the elevator car, a guide for guiding the rope along a path and a device that determines a position of the elevator car. The device includes an elongated code mark pattern provided on the rope, one or more sensors mounted beside the rope for sensing code marks of the code mark pattern, and an analyzer connected with the a plurality of sensors. The one or more sensors sense code marks of the code mark pattern passing by them when the rope moves along its path, and the analyzer determines the current position of the elevator car based on code marks sensed by the one or more sensors during movement of the rope.
