摘要： A tool for lifting open floor gratings and the like provides a solid anchor point on top surface of floor grating to facilitate handling and hoisting the grating. The tool includes a body member having an upwardly biased shaft with a push member with an opening on its upper end and a butterfly hook at its bottom end. During operation, a user pushes down on the push member until it is completely inside the body so that the butterfly hook reaches under the grating. The user then gives a quarter turn to the body member so that the butterfly hook turns and thus becomes wider than the cell of the grating so that it can hook up with two bearing bars as the user releases the push member and the shaft springs back up and the opening gets out of the body. Once this is done, a shackle is installed through the opening, and a steel cable placed therein, ready for lifting and hoisting.
