More Information
Summary:The present invention is implemented by a gantry binary synchronization block-type brake, which comprises: a gantry bracket comprised by a fixedly connected door-shaped frame; braking arms arranged on both sides of the gantry bracket with lower ends of the braking arms hinged to the gantry bracket; braking shoes connected to the braking arms for frictionally braking a braking wheel; a dual brake releaser secured to the gantry bracket for pushing the two braking arms outward synchronously; braking springs provided on the gantry bracket for pushing the braking arms so as to perform normal-mode braking; and a gap adjustment mechanism for adjusting a working gap between the braking shoes and the braking wheel. According to the present invention, the security risks in an elevator tractor or crane can be eliminated, the gap adjustment approach is simple, and reliability and versatility of an operation are considerably enhanced.
