Our patent-pending Shackle Lifting Jig was developed in conjunction with a custom 200 ton spreader beam. The challenge was making the 120 ton shackles (at 240 lbs each) easier to handle when adjusting between lower rigging attachment points. The engineers at Rigging Tree, LLC created a lifting jig that securely cradles the shackle and allows for repositioning of the lower rigging with a crane. The jig hangs from the hook level, with or without the lower rigging attached. Let us design one for your monster sized shackles!
