Multiple Choice

In a wire rope sling, the size of the shackle used in the eye must be ________ the wire rope size.

When a wire rope sling is tied through a shackle, the rope must sit and bend smoothly without being pinched by the pin. The shackle’s opening has to accommodate the rope diameter, so the shackle size should be equal to or larger than the wire rope size. If the shackle is smaller, the rope eye can pinch or bind on the pin as it moves under load, causing extra wear, sharper bends, and stress concentrations that can damage the rope and shorten the sling’s life. A correctly sized shackle provides a clean, gradual bend and proper seating around the thimble, keeping the load path aligned and the rope within its rated strength. In practice, choose a shackle with a bore at least as large as the rope diameter; a larger size is fine and often easier to work with.
