DNV Master Link with Handles - 7 tonnes to 26 tonne WLL

The HA master links with handles are designed specifically for the lifting and lowering of lifeboats, with a working load limit range of 7t to 26t. The master links are manufactured from triple alloy steel in accordance with EN1677, they are individually proof load tested to 2.5 times working load limit in accordance with EN1677 and they are all supplied with charpy impact values of in excess of 42 Joules at -40°C. The links are suitable for use in a temperature range of -40°C up to 200°C without reduction in working load limit.

Features

• Manufactured in accordance with DNV-ST-E271, EN1677-4, ASME B30.26 and AS3776-2015
• 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 (e.g. HA-22 H8 OS+) and Batch Number (e.g. 20C)
• Design air temperature -40° min.
• Average impact energy (charpy) 42 Joules minimum impact resisitance at -40°C up to 50mm diameter
• Operational temperature range is -40° C to + 200°C.
• Hardness range 34 - 36 HRC
• Surface Coating - All master links with handles have a primary application of the Zinc Tough™ corrosion protection coating and a secondary application of orange powder coating.
