The William Hackett SS-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. Safe just became safer!
The design and specification of the William Hackett SS-C4 QP chain hoist includes a working load limit range of 500kg to 50 tonnes. The light load capacity has been tested and certified at 2% of the chain hoist rated capacity. The Quad Pawl (QP) has been endurance tested to twice the industry norm. This product has a safety factor of 4:1 and stainless steel fixings used throughout the hoist. In addition to this the brake components are 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. A unique hand chain joiner is used as a quick and secure method of joining the hand chain.
The hook housing is secured with socket head cap screws/hex head bolts and nyloc insert locking nuts to allow full inspection. The fleeting/cross hauling has been independently tested (test report 2550-7615) for fleeting or cross hauling applications up to 45° from the vertical without deration of the WLL. The load chain is 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). The temperature range is -40°C to +120°C.

FAQS ABOUT Tractel Corso Push Trolley
What is the Tractel Corso Push Trolley used for?
What is the Tractel Corso Push Trolley used for?
The Tractel Corso Push Trolley is a manual push beam trolley that creates a movable suspension and anchor point for lifting equipment on steel beams. It is designed for construction, engineering, maintenance, industrial and material-handling users who need to move compatible lifting equipment along a beam for lifting, load positioning or handling.
How do I choose the correct Tractel Corso Push Trolley?
How do I choose the correct Tractel Corso Push Trolley?
Choose the Tractel Corso according to the required Working Load Limit (WLL) and the supporting steel beam's flange width. The range covers 250 kg to 20,000 kg WLL, with compatible beam widths varying by model from 45 mm to 320 mm. Check the actual beam dimensions and required load against the exact model specification before purchasing, and never exceed the trolley's WLL.
Can the Tractel Corso Push Trolley be used on straight and sloping beam flanges?
Can the Tractel Corso Push Trolley be used on straight and sloping beam flanges?
Yes. The Corso is designed for steel beams with straight or sloping flanges, with its opening manually adjusted to suit the beam profile. The selected model must still accommodate the supporting beam's flange width and be suitable for the required load.
Where and when should I use a Tractel Corso Push Trolley?
Where and when should I use a Tractel Corso Push Trolley?
The Corso is suitable for construction sites, engineering facilities, workshops, maintenance environments and industrial applications where a manually movable lifting point is required. It is useful when compatible lifting equipment needs to be repositioned along a steel beam rather than suspended from a fixed point.
What lifting equipment is compatible with the Tractel Corso?
What lifting equipment is compatible with the Tractel Corso?
The Corso provides a suspension point for compatible lifting equipment including Tirfor, Bravo, Tralift and Minifor. The suspended lifting equipment can then travel manually along the supporting steel beam. The specific trolley, lifting equipment, beam dimensions and WLL must be suitable for the complete lifting arrangement.
What UK regulations and standards apply to the Tractel Corso Push Trolley?
What UK regulations and standards apply to the Tractel Corso Push Trolley?
For workplace lifting operations in Great Britain, applicable LOLER 1998 requirements cover the safe use and thorough examination of lifting equipment, while PUWER 1998 covers relevant work-equipment requirements. These are workplace legal requirements, not product certifications or markings. Tractel states that the Corso is in accordance with the EU Machinery Directive 2006/42/EC. The trolley must be selected and used according to its WLL, beam compatibility and manufacturer's instructions.
