Abstract: 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.

Abstract: An elevator system includes an elevator car, a hoisting machine moving the elevator car in a hoistway, and a hoisting machine brake having one or more brake pads moving into a brake position where the one or more brake pads contact a braking surface to reduce speed of the elevator car when activated to brake. To provide a solution ensuring reliable operation of the brake, the elevator system includes a temperature sensor providing a signal indicating a temperature of the braking surface, and a monitoring unit monitoring operation of the hoisting machine brake, the monitoring unit receiving the signal indicating the temperature and is configured to indicate a brake fault when the indicated temperature during an elevator run has reached an upper limit value or increased with more than a limit value.

Abstract: A safety system of an elevator provided herein may comprise a safety controller, a sensor unit configured to generate a first sensor signal indicating a travelling parameter and to provide the first sensor signal to an elevator drive unit of the elevator, and a signal converter connected to the sensor unit and configured to convert the first sensor signal into a second signal in a second format compatible with the safety controller and to provide the second signal in the second format to the safety controller. The safety controller may be configured to receive the second signal in the second format and to determine, based on the second signal, if there is an emergency condition.
