Abstract
A hoist ring assembly adapted to be arc welded directly to an object to be lifted. A hoist ring mount is provided with the assembly having a generally radially extending flange portion integral with the proximal end of a generally cylindrically bearing portion. The perimeter of the flange portion is welded directly to an object to be lifted by means of a peripheral weld boundary. The bearing portion has a circumference. The length of the peripheral weld boundary is greater than the length of the circumference, thereby reducing stresses applied across the weld while maintaining the load capacity of the assembly after welding. A conventional lifting loop is pivotally mounted to a collar member. The collar member is rotatably mounted on the cylindrical bearing portion of the hoist ring mount. The lifting loop assembly, comprising the lifting loop and the collar member, is detachably mounted on the welded-in-place hoist ring mount. This attachment may be through an internal or external threaded mount, or a quick release detent-locking element configuration.
