William Hackett has taken its extensive knowledge of corrosion protection acquired in the supply of its specialist subsea range to the offshore sector and translated this technology to the newly developed second generation range of Hackett ROV SS-C4 anti-corrosion subsea chain blocks
These hoists can be supplied in the following configurations:
Chain block working load limit capacities available: 3.2t, 5t, 10t, 15t and 20t multi fall units
Single hook suspension unit
Hot stab interface ISO 13628-8 3/8” BSP.1
Hot stab female receptacle
Fishtail direct drive interface
D-link drive
High performance waterproof grease giving superior rust and corrosion protection that will not separate, cake or wash out
Specialist subsea brake material
Lightweight sturdy handles using 316L stainless steel
Operating temperature range -40 °C to +55 °C
Stainless steel fixing and fasteners
3D Models available
All the above hoist configurations can also be supplied with the following options
Calibrated Grade T (8) load chain to BS EN818-7 zinc plated
Calibrated Grade S (6) 316L stainless steel load chain
Complies with the Lifting Equipment Engineers Association ‘Code of Practice for Selection, Management, Use, Maintenance and Examination of Hand Chain Blocks and Lever Hoists in The Offshore Environment including Subsea’.
