    The William Hackett 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, enabling finer adjustment and tensioning capability while maintaining pawl/ratchet engagement. This enhances the hoist capabilities.

    The WH C4 QP is perfect for everyday use, one-off lifts, or as part of a fleet. We provide a full range of spare parts and can offer training on safe use and inspection.

    • TWO YEAR WARRANTY
    • Overload protection available
    • Low-temperature option (–40°C) available
    • Complies with ASME B30.16

    Description

    SAFETY FACTOR: 4:1 

    TEMPERATURE RANGE: -20°C to +120°C (optional -40°C available upon request) 

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

    QUAD PAWL (QP): Delivers twice the engagement points, giving you noticeably finer, more precise load adjustments than standard two-pawl designs.

    SAFETY LATCHES: hooks are fitted with heavy duty cast steel latches. The latch and hook tip are interlocking, 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. Certified to angles up to 60° from the vertical without deration of the WLL. 

    LOAD CHAIN: fitted with load chain that fully complies with BS EN818-7 Grade T (8). 

    MANUFACTURED AND PROOF TESTED in the U.K.
