ABSTRACT:
A hoist swivel shackle assembly used with others to hoist heavy objects such as dies and molds. The shackle includes a "U" shaped shackle member pivotal on a swivel body which is rotatable about an orthogonal axis on a base. Long term distortion of the shackle member is minimized by flanges on the ends of the legs of the shackle that slidably engage side bosses on the swivel body to absorb outward loading on the shackle. The shackle is pivoted to the swivel body member by a pair of pins with annular recesses, fixed in a pair diametrally opposite pin receiving bores in the swivel body member. These pins are held in the swivel body member by pressing a softened material into threaded bosses in the swivel body forcing it around the pins and into their recesses. Overloading the swivel shackle assemblies is minimized by an indicator that tells the operator when he has exceeded the safety angle of the shackle member.
