AOS-DNV 2.7-1 Offshore master link
Sometimes standard master links are too narrow for wire rope slings, meaning that wire rope thimbles don‘t have sufficient space and/or room for manoeuvre. It can also be the case, that rings are too narrow for large crane hooks.
Master link for offshore container lifting purposes in welded chain slings/or wire rope slings. Particularly suited for wire rope slings due to the larger width compared to AW-DNV 2.7-1, to give space for wire rope thimbles. Can be used for larger crane hooks as AW-DNV 2.7-1 and MW-DNV 2.7-1 with comparable thickness.
For manufacture of I-leg and II-leg slings. Allocation to max. usable crane hooks according to DIN 15401 stated in table.
CE marking.
Type approved in accordance with DNV 2.7-1. Type approval certificate no. S-8254.
