Abstract
A cable grab assembly includes a body having a longitudinally extending internal cavity disposed therein. A piston is disposed in the cavity and is axially moveable between a first position and a second position. At least two grab arms are hingedly attached to a bottom end of the body. A linkage assembly operatively couples the piston and the at least two grab arms such that movement of the piston between the first position toward the second position causes the at least two grab arms to pivot inward from an open position toward a closed position. A shear-pin restrains the piston to the first position. At least one spring element is disposed between the piston and an end of the cavity to shift the piston from the first position toward the second position to capture a broken cable when the shear-pin is sheared.
