ABSTRACT:
A cable grab safety device which releasably attaches a workman's safety belt or harness lanyard to a vertically extending safety steel cable or the like. The device includes a primary frame assembly constructed of an elongated U-shaped bracket having a pair of spaced apart parallel side plates which is adapted to fit around the cable. A secondary frame assembly also comprised of a pair of side plates is adapted to fit within the U-shaped bracket after the cable is inserted. The secondary frame assembly carries a brake mechanism in the form of a pulley mounted in an elongated slot so as to be movable toward or away from the cable and a lever adapted to be attached to a worker's lanyard for moving the pulley so as to engage the cable in the event of a fall. An elongated bent pin connected between the primary and secondary frame assemblies allows for limited pivotal and axial movement between them to thereby allow the cable to be inserted into the U-shaped bracket. A separate locking pin passes through aligned openings in the primary and secondary frame members to secure them together.
