<p>The brake uses a slow brake feature whereby a positioning member, such as a lever, is actuated directly via a first spring to cause braking in response to faults only on the weaving side as well as a fast or normal brake feature whereby the positioning member is able to transmit the braking force of a second spring to effect braking in response to faults on the weaving side or mechanical side. The second spring acts on the positioning member via an abutment which is moved against the positioning member upon release of the second spring. The second spring can be released via an electromagnet in response to a weaving fault on the weaving side or by a stop-motion rod in response to a mechanical fault.</p> |
