Abstract
A shackle assembly used for lifting an object includes clevis members that each mount to a pin, and are moveable about the pin and into orientations for attachment to the object. Each clevis member includes a main body with an opening that receives the pin. A set of spaced apart and parallel legs project from the main body in a direction away from the pin. Spherical bearings are set between the pin and each main body that enable each clevis member to move with multiple degrees of freedom about the pin. Fasteners project between the free ends of each set of legs, and which are for engaging the object.
Claims16
A shackle assembly for use in lifting an object comprising:
- an elongated cylindrical pin having an axis;
- first and second planar clevis members coupled with the pin, each clevis member comprising a main body portion and spaced apart legs that extend from an end of the main body portion and parallel to one another to define a set of legs;
- bearing assemblies disposed between the clevis members and the pin, each bearing assembly comprising,
- an inner race having a spherically profiled outer surface and mounted onto the pin, and
- an outer race set in a main body portion of a one of the clevis members and having an inner surface profiled complementary to the spherically profiled outer surface of the inner race, so that each clevis member is selectively rotational about an axis parallel with the axis of the pin, and also selectively rotatable about axes not parallel to the axis of the pin;
- a tang element coupled with the pin between the clevis members, and having an end distal from the pin that is configured to be engaged by a lifting device;
- a fastener coupled with each set of legs and that selectively attaches to an object to be lifted.
A shackle assembly for use in lifting an object comprising:
- a pin;
- clevis members that couple to the pin and spaced apart from one another, each clevis member comprising, a main body coupled with the pin, arms that project from the main body and are spaced apart, and a fastener that extends between the arms, so that when the fastener is inserted into an attachment point on an object, the clevis member is attached to the object;
- bearing assemblies between the pin acid clevis members, where the bearing assemblies each comprise an outer race disposed in an opening formed in a clevis member, and an inner race axially affixed to the pin, and wherein the inner and outer races contact one another along spherically shaped surfaces;
- and
- a tang member coupled with the pin and configured for attachment to a lifting line.
