Abstract: A chain is provided which includes a plurality of interconnected chain-links. At least one chain-link of the chain has a braided core which includes a first primary strand having polymeric elongated elements having a tenacity of at least 1.0 N/tex. The braided core is braided from at least 2 consecutive turns of the primary strand. Also disclosed is a braided endless shaped element suitable as chain-link for the chain as well as a chain which has a tenacity (Ten) in N/Tex and a combined titer of the 2 legs of the chain-link having polymeric elongated elements (T) in MTex satisfying the relationship of Ten≥0.50*T−0.05.

Abstract: A rope system (10, 20) comprising a splice structure (12, 22) with an intact portion (23) comprising at least 8 intact strands (32, 34), and a disassembled portion (26) comprising at least 4 loose strands (30), wherein the intact portion (23) is a braid of at least 4 S oriented (32) and at least 4 Z oriented intact strands (34), wherein at least one loose strand (30) of the disassembled portion (26) passes under and over intact strands (32, 34) of the intact portion (23), and at least one loose strand (30) passes under at least one X-tuck (38) of intact strands (32, 34). By this means the splice length can be minimized resp. slippage of the splice at high loads can be avoided.
