WH C4 QP Chain Hoist
The William Hackett C4 QP chain hoist meets and exceeds the requirements of the following international standards:
Irish Standard IS EN13157:2004 + AI:2009
The William Hackett C4 QP chain hoist incorporates the 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.
- Capability to provide finer adjustment and tensioning operations.
The design and specification of the William Hackett 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 rated capacity.
- QUAD PAWL (QP): Endurance tested to twice the industry norm.
- SAFETY FACTOR: 4:1.
- 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: fitted with load chain that fully complies with international standard IS EN818-7 Grade T (8).
- TEMPERATURE RANGE: -20°C to +120°C
- 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.
