Abstract: The invention relates to a chain comprising a plurality of interconnected chain-links wherein at least one chain-link comprises a braided core comprising a first primary strand comprising polymeric elongated elements wherein the polymeric elongated element has a tenacity of at least 1.0 N/tex wherein the braided core is braided from at least 2 consecutive turns of the primary strand. The invention also relates to a braided endless shaped element suitable as chain-link for said chain. The invention further relates to a chain wherein the chain has a tenacity (Ten) in N/Tex and a combined titer of the 2 legs of the chain-link comprising polymeric elongated elements (T) in MTex, with 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.
