William Hackett WH SS C4 QP Subsea Hand Chain Hoist

Corrosion Resistant C4 SS QP Series Subsea Chain Block

The William Hackett SS C4 QP Chain Hoist is designed, manufactured and proof load tested in the UK. It incorporates four-pawl mechanical engagement functionality.

The design and specification of the William Hackett SS-C4 QP chain hoist includes

• WORKING LOAD LIMIT RANGE: 500kg to 50 tonnes.
• LIGHT LOAD CAPABILITY: tested and certified at 2% of the chain hoist's rated capacity.
• QUAD PAWL (QP): Endurance tested to twice the industry norm.
• SAFETY FACTOR: 4:1
• STAINLESS STEEL FIXINGS: used throughout the hoist
• BRAKE COMPONENTS: corrosion-protected.
• SAFETY LATCHES: hooks are fitted with heavy-duty cast steel latches. The latch and hook tip are integrated, creating a strong and robust hook closure.
• HOOK OVERLOAD AND TRACEABILITY MARKS: hooks have overload indicator marks on either side of the hook throat (500kg to 10t). Both top and bottom hooks are embossed with a batch code, manufacturer's mark and the working load limit for full traceability and compliance to international standards.
• HAND CHAIN JOINER: A unique hand chain joiner is used as a quick and secure method of joining the hand chain.
• HOOK HOUSING: Secured with socket head cap screws/hex head bolts and Nyloc insert locking nuts, allowing for full inspection.
• FLEETING/CROSS HAULING: independently tested (test report 2550-7615) for fleeting or cross hauling applications up to 45° from the vertical without deration of the WLL.
• LOAD CHAIN: corrosion-protected Grade 8 load chain offered as standard, with the option of calibrated Grade S (6) 316L stainless steel load chain, hand chain and bottom hook (stainless steel bottom hooks are only available for 500kg and 1 tonne units).
• TEMPERATURE RANGE: -40°C to +120°C.
• MARINE PAINT:
  - AkzoNobel Interpon D1010 Premium
  - Corrosion Resistance 1,000 hours according to DIN EN ISO 9227.
• PROOF TESTED: 500kg to 10 tonne hoists are proof tested to 1.5 times the Working Load Limit. 15-tonne to 50-tonne hoists are proof tested to 1.25 times the Working Load Limit.
• OVERLOAD LIMITER: available as an option upon request.
• MANUFACTURED AND PROOF TESTED in the U.K.

The William Hackett SS-C4 QP chain hoist features a four-pawl mechanical engagement system. The unique and patented pawl design enhances the capabilities of the hoist allowing all four pawls to engage with the ratchet gear in an offset configuration, allowing finer adjustment and tensioning capability while maintaining pawl/ratchet engagement. This improves the hoist's:

• Resilience to failure.
• Capability to provide finer adjustment and tensioning operations.
  - SAFE JUST BECAME SAFER!
