VOS-DNV 2.7-1 Offshore master link assembly

Standard master links are normally too narrow, meaning that they don‘t fit correctly/optimally on large crane hooks. Standard transition links are mostly too narrow for wire rope slings, meaning that wire rope thimbles don‘t have sufficient space and/or room.

Master link assembly for offshore container lifting purposes in welded chain slings and/or wire rope slings. AOS type master links are used as the main link. Therefore, they can mostly be used for larger crane hooks than in VW-DNV 2.7-1 and VAMW-DNV 2.7-1 with comparable thickness. BOS are used as transition links. Particularly suited to wire rope slings, due to the inner width to give space for wire rope thimbles.

For the manufacture of IV-leg chain and wire rope slings. Allocation to max. usable crane hooks according to DIN 15401 stated in table.

CE marking.
Links type approved in accordance with DNV 2.7-1. Type approval certificate no. S-8254.
