Abstract
A cable brake has an electromagnet for selectively releasing a mass to fall down guide rods under the effect of gravity and impact a trigger lever to release a crossbar from a pawl, whereupon pressure springs move a brake plate against a cable strand to halt the cable strand. The pressure springs extend between a first pressure plate at the brake plate and a spaced second pressure plate that can be displaced along a path by a cooperating screw and nut to pre-stress the pressure springs. The pressure springs are relaxed in one end position of the path whereby the crossbar connected to the first pressure plate by a release bar is engaged by the pawl in a starting position.
