The present invention provides an elevator brake and a cushion replacement method of the elevator brake, and relates to the field of elevator braking technologies. The elevator brake of the present invention includes a first block and a second block that collide with each other during braking, and a cushion located between the first block and the second block, and further includes a cushion support detachably mounted on the first block or the second block, where the cushion is disposed on the cushion support. A cushion of the elevator brake in the present invention can be replaced without disassembling the whole elevator brake.

An elevator system and/or method executed by an elevator controller for detecting a fault within the elevator system. The elevator controller utilizes the fault to disable a drive control portion of the elevator controller and activate a drive u-stop control portion of the elevator controller. The drive u-stop control portion of the elevator controller generates a signal based on at least one of a speed estimation, a velocity profile, and feedforward information. The elevator controller applies the signal to an inverter connected to the elevator controller to execute the urgent stop of an elevator car of the elevator system.

An elevator brake for braking and holding an elevator car in an elevator installation, and a method for returning and subsequently holding the elevator brake in a standby position, includes a first actuation device for actuating a first brake lining. The first actuation device includes an electromagnetic holding and catch device that holds an energy store, in the form of a spring accumulator, in a loaded state and releases the energy store when required. The electromagnetic holding and catch device includes a plurality of electromagnets that act directly or indirectly on the energy store by a lever distribution. The electromagnetic holding and catch device alternatively, or additionally, can include a traction device that holds the first brake lining in the standby position. The traction device is looped around a bollard or capstan and held at a free end by at least one electromagnet.

An elevator brake braking and holding an elevator car in an elevator system includes a first brake lining having a first actuating device and a second brake lining, which brake linings cause braking in interaction with a braking strip or brake disk. A second actuating device is associated with the second brake lining, and the second actuating device moves the second brake lining toward the first brake lining, if necessary, thus clamping and braking the braking strip or the brake disk between the second and first brake linings. The first actuating device moves the first brake lining toward the second brake lining to clamp and brake the braking strip or the brake disk between the first and second brake linings. The first and the second actuating device operate according to different principles of operation.
