25.0t SS19 Subsea Lever Hoist 25.0t 

The SS19 Subsea Lever Hoist has been meticulously designed to thrive in maritime, offshore, and corrosive environments. It features a one-piece construction pinion gear and a globally patented Quad Cam Pawl System, providing superior anti-corrosion properties and additional safety benefits not found in other lever hoists. This makes the SS19 an optimal tool for marine and extreme applications.

It has been rigorously tested and performed well in a range of challenging environments.

Developed initially with the goal of giving key stakeholders within the Oil and Gas Industry a hoist that could be certified for safe use subsea whilst meeting all the requirements of IMCA DO28 Rev. 1 “Guidance notes for offshore lever hoists”, the SS11 meets and exceeds these requirements, as well as other industry client specifications whilst conforming to standards such as BS EN 13157: 2004+A1:2009, ANSI/ASME B30.21-2005, AS1418.2 and SANS 1636.

The SS19 includes a unique rotational inertia driven torsion switch brake and freewheeling system. This brake system was designed by Tiger's research and design team to counter known failure modes in commonly used and copied longitudinal “push-pull” mechanisms or traditional style “Weston” type brake systems used on alternative lever hoists which allow easy ingress of foreign particles into the mechanism that could affect hoist operation. This Tiger brake system is now a proven design with many thousands of hours of empirical evidence as proof of design and efficiency. This design removes the need for inefficient old style longitudinal disengagement methods of pulling the brake system apart to facilitate freewheeling. This highly efficient method of operating is not only safer but easier for the operator whilst measurably increasing the brake take up efficiency rate.

With over 50 years of professional manufacturing experience, Tiger’s commitment to innovation and customer satisfaction mean we will continue to develop and improve our products by communicating and working with our customers.
