Offshore & Subsea HA Master Links OS+ - 4.1 tonnes to 250 tonnes WLL

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.
