The horizontal shackle permits a beam to be lifted with the web in a near horizontal position by placing the clamp on the load with the shackle positioned over the web, and between the flanges. With a beam lying in a horizontal position, and the clamp placed with the shackle over hanging the flange, the beam can be lifted, turned 90 degrees, and raised in a vertical position. The Model ASTL includes all of the feature of the Model AST plus a linkage which permits the tool to be removed remotely by setting the load down with the sling slack, then lifting the crane hook.
