Offshore & Subsea HA Master Links OS+ - WLL Range 4.1 tonnes to 250 tonnes
Certified to International Standards: DNV2.7-1, DNV2.7-3, BSEN ISO 10855-2, EN1677-4, ASME B30.26, API-2CCU - Aug. 2017. WLL Range 4,100 kg to 250,000 kg
Model:
OASH-5140


The HA range of Grade 8 master links and quad assemblies are widely used for offshore rigging and lifting sets for containers and are the industry leaders globally based on the following:
- Product available in diameters from 16mm up to 120mm and working load limits from 4.1 tonnes to 250 tonnes.
- The links are manufactured from triple alloy steel in accordance with EN1677, which includes individually proof load tested to 2.5 times working load limit and 100% MPI.
- MPF (Manufacturing Proof Force): 2.5 x 9.81 x Working Load Limit (kN) (min.).
- BF (Break Force): WLL x Factor of Safety.
- WLL (Working Load Limit) (tonne) @ 45° to vertical.
- Factor of Safety: 5:1.
- Embossing: as per Description column and Batch Number.
- Design air temperature -40° min..
- Average impact energy (charpy) 42 Joules minimum impact resistance at -40°C up to 50mm diameter.
- Operational temperature range is -40° C to + 200°C.
