    摘要： According to an aspect, there is provided an elevator car parking brake comprising brake pads and an actuator configured to move the brake pads with respect to a guide rail. The elevator car parking brake further comprises levers, each having an associated brake pad; and at least one screw associated with the actuator and rotatably fixed to at least one lever via at least one attaching member. In a braking operation, the actuator is configured to rotate the at least one screw in a first direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move towards the guide rail. In a brake release operation, the actuator is configured to rotate the at least one screw in a second direction with respect to the at least one attaching member, thus causing the levers with the brake pads to move away from the guide rail.

    摘要： 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.

    摘要： An elevator system includes: an elevator control; a plurality of individually movable elevator cars driving in an elevator runway system including at least one elevator runway, preferably at least two elevator runways, whereby the number of elevator cars is higher than the number of elevator runways in the runway system. The elevator cars are movable in the elevator runway system via at least one drive system. Each of the elevator cars is provided with an identifier. The elevator system includes at least one reader device for the identifier and a car handling module in the elevator control processing the information on the elevator cars and their identifiers in connection with their position in the elevator system. The elevator system includes elevator cars differing in at least one parameter (differing parameter). The memory of the elevator control includes car parameters of the cars in operation in the elevator system and the elevator control is configured to use the car parameters in the control of the elevator system. The identifier includes information at least about the differing parameter, and the car handling module is configured to put out of use the car parameters of an elevator car that is to be put out of operation and/or to introduce the car parameters of an elevator car which is to be put into operation.

    摘要： Modern elevators involve a plurality of ropes and wheels for ropes in a variety of different functions related to the operation and security of an elevator. The wearing of a rope and a wheel may be inspected by scanning a profile of a wheel or ropes on a wheel. When a rope or a wheel is worn the profile will be lower than in the normal situation. Depending on the difference to the normal situation an appropriate action may be taken.

    摘要： The safety circuit includes a safety switch or a series circuit of safety switches, which includes an input for an electrical safety circuit signal as well as an output, in which the electrical safety circuit signal being supplied to the input is present when all the safety switches are closed. The safety circuit also includes a cable including an optical fiber as well as a transmitter circuit for the optical signal, the output of which circuit is connected to the cable including an optical fiber. The input of the transmitter circuit is connected to the output of the aforementioned safety switch or of the series circuit of safety switches, and the transmitter circuit is configured to transmit in the optical fiber of the cable the safety circuit signal that is present in the output of the safety switch or of the series circuit of safety switches.
