WH ROV SS C4 QP Chain Hoist - Hydraulic

Brand:

Standards: BS EN13157:2004 + A1:2009, ASME B30.16-2022, AS1418.2-1997, SANS 1594:2007, NORSOK R-002:2017+AC:2019/AC:2023

Summary

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

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.

The ROV SS C4 QP has been developed to be used by underwater remotely operated vehicles (ROV). A mounted grab frame is attached the hoist giving an easy grab point for the ROV manipulators to hold onto. The hoist can be driven manually by a Fishtail, D Link attachment or by hydraulics.

The SS C4 QP block head has been specifically designed for subsea use.

We provide a full range of spare parts and can offer training on safe use and inspection.

WLL Range: 3.2t - 20t
Proof Load Test: 3.2t - 10t = 1.5 x WLL. 15t - 20t = 1.25 x WLL
Safety Factor: 4:1
Temp Range: -20°C to +120°C

Applications

Key Features

LIGHT LOAD CAPABILITY: tested and certified at 2% of the chain hoist rated capacity.

QUAD PAWL (QP): Endurance tested to twice the industry norm.

MARINE PAINT:
- AkzoNobel Interpon Redox Triplex
- Corrosion Resistance 1,000 hours according to DIN EN ISO 9227.

HYPERBARIC TESTED: at 3,000 metre water depths.

OPTIONAL EQUIPMENT: Hot Stab, Fishtail, D Link and Torque Buckets as well as bespoke fittings such as ROV Shank Hooks, Shackles and Sling Hooks.

NEW DESIGN FEATURE: As an option for the ROV chain hoist a hand wheel can be incorporated into the chain hoist design. When the hoist is topside, hand chain can be fitted to the hand wheel to allow manual adjustment of the load chain.

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 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 to allow 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 and hand chain.

OVERLOAD LIMITER: available as an option upon request.
