ABSTRACT:
A single line grab system including a grab suspended by a single line from a carrier. A head assembly is connected to the grab from above the grab and is vertically movable with respect thereto. A first end of the line is anchored and second end of the line is selectively extensible and retractable. A retarder system selectively engages a portion of the line. In one embodiment of the grab system the retarder is mounted on the head assembly and the first end of the line is anchored to the carrier. In an alternate embodiment of the grab system the retarder is mounted on the carrier and the first end of the line is anchored to the head assembly. A method for operating a grab system essentially involves two variables: first, the line may be selectively withdrawn or fed and, second, the retarder may be selectively disabled or applied to a portion of the line. Using these two variables, the grab or bucket may be selectively opened or closed and selectively raised or lowered.
