William Hackett’s New Lever Hoist – SSL5, a Game Changer in Offshore and Subsea Lifting Projects
New generation of lever hoists offer the highest levels of safety and performance with the world’s first quad pawl mechanism launched during ADIPEC 2019.
• SAFETY: enhanced built-in failure resilience. Patented quad pawl technology allows the SSL5 to operate safely should individual pawls or springs fail. With double the number of offset pawls in a lever hoist, from two to four, the load is spread securely against the ratchet gear to provide increased redundancy and resilience to failure for the user.
• COST: 80% reduction in capital spend on new hoists per mobilisation with warranted multi-immersion use. SSL5 reduces purchase, servicing and transportation costs, which delivers better cost efficiencies on projects and big savings for operator budgets.
• PERFORMANCE: SSL5’s dual action brake mechanism and intelligent inertia capability improves the user’s safety and rigging productivity in both subsea and topside applications.
• DURABILITY: lighter in weight thanks to the quality of design and materials used, the SSL5’s performance to weight ratio reduces the risk of injury to the user during handling such as in logistics and rigging (due to its reduced unit mass).
• ENVIRONMENTAL CREDENTIALS: multi-immersion use reduces the number of hoists needed on a mobilisation, resulting in less single-immersion hoists being decommissioned after use, which is better for the environment and a more sustainable solution for industry.
• PROVEN COMPLIANCE: meets with EN 13157, American Standard ASME B30.16-2012, Australian Standard AS1418.2-1997, NORSOK R-002: 2017, South African Standard SANS 1594:2007, DNV verification for multi immersion and company standard BP (DEV-AAD-SS-SD-BP-0545).
William Hackett, world-leaders and original pioneers of offshore lifting hoists and chains, take a major step forward with the launch of SSL5, incorporating its patented quad pawl (QP) mechanism – positioned as the safest and most efficient offshore and subsea lever hoist in the world.

“It’s a piece of engineering innovation that will transform safety levels globally when lifting offshore and in subsea operations using lever hoists,” says Ben Burgess, Director at William Hackett. “We’ve designed this hoist to provide the highest level of safety, with increased levels of redundancy and resilience to failure. Its QP offset load bearing mechanism is the best in the market, and it offers enhanced operating performance compared to twin pawl products.”
The patented QP mechanism synchronises a set of four pawls which constantly work together to minimise
