Abstract
A load lifting device for lifting a load. The load lifting device includes a primary plate, a lifting attachment that receives a hook of an overhead suspender, and a clamping system that can clamp a load onto the lifting device between two jaws. The clamping system can have a coarse adjustment and a fine adjustment. The coarse adjustment selectively connects a jaw to the primary plate at a plurality of discrete connection points, and the fine adjustment mechanism selectively moves a contact point of the first jaw toward a first end portion of the load. A method for lifting a load includes positioning the load lifting device horizontally above a load, clamping the load with a clamping system, and imparting a vertical force on an end portion of the load lifting device to rotate it from horizontal to vertical.
