The William Hackett SS-L5 QP Utility is the first lever hoist to incorporate 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 gear engagement. The pawl springs are totally enclosed in the brake chamber and the patented pawl design allows, however unlikely, for both pawl springs to fail and for the quad pawls to maintain full functioning engagement with the ratchet gear making the hoist safer. William Hackett verifies that the SS-L5 QP can be safely used over a 21-day single immersion and a 31-day multi immersion period which offers operators considerable financial advantages. The design features, manufacture, verification testing and guidance for use, maintenance and storage of the SS-L5 QP has also been developed in line with: BP Document DEV-AAD-SS-SD-BP-0545: 'Specification and compliance requirements for lever hoists used subsea on BP projects'.
Light load brake function is critical in overhead line tensioning operations where the load on the hoist is likely to vary. All SS-L5 QP’s are tested and certified to function at 2% of the rated WLL. In addition to lighter weight, the SS-L5 QP has been designed to minimise the ingress of contaminates into the brake mechanism. All of the steel painted components go through a multi-layer coating system, involving a pre-treatment, a primer layer and an AkZoNobel Interpon top coat. This high durability coating gives 1500 hours corrosion resistance according to ISO 9227. Stainless steel components are used within the SS-L5 QP. These include pawl springs, circlips, cap screws, nuts, washers and identification plates.
