Offshore Swivel Hoist Ring


The William Hackett offshore swivel hoist ring has been designed for use in the harshest of environments.

• Manufactured and tested in accordance with EN1677-1
• All swivel hoist rings meet or exceed all the requirements of ASME B30.26
• All load bearing components are manufactured from alloy steel and quenched and tempered
• Design factor 4:1
• All load rated components are magnaflux crack detected
• Proof tested to 2.5 times the working load limit

Benefits of sherardised technology
• Non-interference with metallurgical properties: The low temperature application of the coating process does not have any effect
on the hardness.
• Zero risk of hydrogen embrittlement: Many coating processes such as galvanizing and electroplating bring with them the risk of
embrittlement. This advanced technology poses a zero risk of hydrogen embrittlement.
• Corrosion Protection: The zinc-iron alloy coating provides corrosion protection and resistance to pitting.
• Excellent bonding surface and spark free: The zinc layer is spark free providing an excellent bonding surface ideal for further
• Abrasion resistant: An abrasive resistant coating on average ? to 15 ? thickness.
• Environmentally friendly process: The zinc vapour thermal diffusion process is environmentally friendly (a non-toxic, heavy metal
free process).
• Non-destructive testing: None-interference with non-destructive test methods such as Eddy current and magnetic particle testing.
