ABSTRACT:
A hoist device for fixed engagement to a threaded bore on an outer surface of a load member is provided. The hoist device comprises a load engaging stud with a force supporting head, a cylindrical body portion with a lower annular bearing shoulder and a threaded shank depending from the annular shoulder of the body portion. A base member having a body portion with a central passage through the base member and allowing a free swivel engagement of the base member with the load engaging stud is provided. The central passage of the base member, having an upper recess for capturing the force supporting head and an upper annular shoulder for transmitting a force from the base member to the supporting head when the base member is pulled from the load member is also provided. A hoist ring is secured between the support member and the base member while allowing the base member to swivel around the stud. A slot in one of the members captures the hoist ring while allowing the hoist ring to pivot in the slot. The stud includes a tool driving portion and a force supporting head, the tool driving portion includes the tool engaging portion and the stud and access openings in one of the members registered with the tool engaging portion when one of the members and the stud are in a given relative angular position. In such position, an elongated tool can be extended through the opening into the tool engaging portion to rotate the stud and members in unison until the lower shoulder engages the surface of the load member.
