摘要： A method for diagnosis and/or maintenance of a brake configured to apply braking force to a hoisting machine of a transportation system includes controlling the brake to start a brake control action, e.g. an opening and/or a closing action of the brake; monitoring the brake to detect a response of the brake to the brake control action, wherein in case of the response the response is detected in a predefined manner; measuring a brake operating time interval from a first point in time of starting of the brake control action until a second point in time of monitoring the brake to detect the response; and, if either the response has not been detected until the brake operating time interval reaches and/or exceeds a predetermined threshold or the response has been detected after the brake operating time interval reaches and/or exceeds the predetermined threshold, establishing an information indicating that an operation of the brake should be modified. A computer program realizing the method and a brake apparatus configured to execute the method are also disclosed.

摘要： According to an aspect, there is provided an elevator car parking brake comprising a brake carrier having a first plate and a second plate, the plates being spaced from each other and positioned to enable a guide rail to travel within the space between the plates, a caliper movably connected to the brake carrier, brake pads, and an actuator configured to move the brake pads against a guide rail in a braking operation. The elevator car parking brake further comprises at least one first compression spring arranged between the first plate of the brake carrier and a brake pad directly associated with the actuator; and at least one second compression spring arranged between the second plate of the brake carrier and the caliper, the first and second compression springs being configured to keep the brake pads substantially centered with respect to the brake carrier.

摘要： An elevator safety brake unit, an elevator including at least two of the safety brake units, and a method for testing the safety brake units are disclosed. Each safety brake unit includes a frame part, a movable composition movably supported on the frame part, a compression spring assembly associated with the movable composition, and adapted to activate a braking by pushing the movable composition forward, and a coil assembly of an electromagnet disposed in the frame part and adapted to deactivate the braking by pulling the movable composition backwards. Each movable composition includes at least two movable elements, one compression spring for each movable element, and at least one coil assembly adapted to deactivate the braking by pulling the at least two movable elements backwards.

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.
