Abstract

A lifting lug apparatus comprises a mounting plate adapted for attachment to an upper portion of an object to be lifted. A lifting lug defines a hook aperture and is pivotally attached to the mounting plate such that the hook aperture is movable from a lateral position, wherein the hook aperture is oriented in a lateral plane extending outward from the mounting plate and outward from an attached object to be lifted, to an upright position, wherein the hook aperture is oriented in an upright plane extending upward from the mounting plate. The lifting lug is biased toward the lateral position so that a lifting hook can conveniently be engaged in the hook aperture and when the object is lifted the lifting lug pivots upward to reduce stress on the connection between the lifting lug and the object.
