ABSTRACT:
An industrial emergency brake is disclosed having a pair of braking members disposed on opposite sides of a brake member such as a brake disc. A stack of Belleville washers constantly urge each brake member towards engagement with the brake member. A retaining member normally keeps each of the braking members out of engagement with the brake member. The retaining member is a frangible explosive component containing an explosive charge and fractures to permit the stack of Belleville washers to urge the braking member into engagement with the brake member. The retaining member may be a bolt, fixed between a fixed support and the braking member, a nut bearing against the fixed support and in engagement with a stud bolt or a washer between a nut and the fixed support. A set of jacks may be used to disengage the brake.
