Abstract:
Disclosed is a connection fixture capable of attaching without the use of bolts to an upper portion of a structure to be lifted to facilitate the lifting thereof. In one embodiment, the connection fixture includes an outer angle iron and an inner angle iron attached in a vertically slideable relationship with respect to one another between an open position and a closed position. In the open position, the connection fixture can be positioned to engage a plurality of holes in an upper horizontal lip of the structure to be lifted. In the closed position, the upper lip is securely captured between the outer angle iron and the inner angle iron. A shackle can be secured through holes in the connection fixture. In another embodiment, the connection fixture includes first and second planar elements between which can be captured an upper portion of the structure to be lifted.
