Abstract: A chain coupling device comprising a ring member adapted to be coupled to a hoisting mechanism, and a chain coupling mechanism adapted to be coupled to at least two hoisting chains (101, 201). The chain coupling mechanism comprises a unitary anchoring body (1) being made in one piece and being securable to the ring member. The unitary anchoring body has at least two pairs (6a, 6b; 7a, 7b) of anchoring projections, each pair of anchoring projections being provided with a detachable anchoring pin (6d, 7d) for anchoring an end link (102, 202) of an associated hoisting chain (101, 201) to the unitary anchoring body. The unitary anchoring body also has at least one pair (10a, 10b; 11a, 11b) of coupling projections being located at a distance from a corresponding pair of anchoring projections and being provided with seating surfaces for accommodating one (204) of the links of the associated hoisting chain.

Abstract: A shears coupling, particularly for interconnecting two load supporting members, such as a looped cable and a chain, by the aid of a mating coupling member, comprises a pair of two-armed levers which are rotatably interconnected by means of a common pivot. Each lever has an arcuate shank, which is located substantially in the same plane as said common pivot and has a free end which, when the shears coupling is in its closed operative position, overlaps the free end of the other arcuate shank for forming a substantially closed eye. The other arm of each lever has at least one lug, which projects, preferably radially, with respect to the pivot and is provided with a through opening, which substantially registers with the respective openings of the other lugs in said closed position.
