Abstract (en)
[origin: WO2016045932A1] The invention relates to an elevator brake (20) for braking and holding an elevator car (2) in an elevator installation (1), a corresponding elevator installation, and a method for returning and subsequently holding an elevator brake in a stand-by position. The elevator brake contains a first actuation device (25) for actuating a first brake lining (22). Said first actuation device (25) comprises an electromagnetic holding or catch device (36) which can hold an energy store (32), in the form of a spring accumulator, in the loaded state and release it when required. Said electromagnetic holding or catch device (36) contains a plurality of electromagnets (38, 38a-38h) which can act directly or indirectly on said energy store (32) by means of a lever transmission (L1/L2). Said electromagnetic holding or catch device (36) alternatively, or additionally, comprises a traction means (43) which can hold the first brake lining (22) in its tensioned stand-by position. The traction means is looped around a bollard or capstan (44), and it can be held, by means of a free end of said traction means (43), by at least one electromagnet (38, 38a-38h).
