SS19 Subsea Lever Hoist Our subsea lever hoist, the SS19, has been designed and developed over a number of years for use primarily in subsea, offshore or corrosive environments. The unique design features – including the one piece construction pinion gears and our globally patented Quad Cam Pawl System, along with the superior anti-corrosion properties incorporated in this range, give it significant safety advantages over other lever hoists. This makes the SS19 subsea lever hoist the ideal tool for all marine and extreme applications. It has been fully challenged and successful in the wide variety of extreme conditions it has been exposed to.
Make lifting safer by installing a load limiter device to manual hoisting equipment. The Tiger overload protection triggers a slipping mechanism to the hoist’s drive system when attempting to operate past its limit, making it impossible to continue lifting while lowering is still possible. The overload clutch is factory set and should only be adjusted or repaired by a Tiger authorised service centre.
“EZ Check” hooks, cross-hauling capabilities and load limiters to ensure that your safety is never compromised.
Tiger chain blocks and lever hoists fitted with overload limiters are DNV GL Verification tested according to NORSOK R-002.
PROCB (TCB) Professional Chain Block The PROCB is manufactured from the highest quality steel materials precisely machined in our own factory, offering a lightweight, compact and rugged construction, producing an exceptionally strong product resistant to impact damage. The especially low headroom allows for easy installation in the most restricted environments. The unique design features – including our patented Quad Cam Pawl System – give it significant safety advantages over standard chain blocks and make the PROCB chain block the ideal tool for long term use with low maintenance and servicing costs.
• The latest Tiger chain block load limiter was designed six years ago with an innovative ball bearing slipping clutch, moving away from the previous friction disc slipping clutch design to give more accurate results • Set at 125% of the hoists rated capacity • Tiger hoists fitted with load limiters can be recognised by the yellow handwheel or grip ring Load limiters can be fitted to PROCB/SS20 chain blocks and PROLH/SS19 lever hoists. Chain Blocks Our chain blocks are robust and reliable and have a variety of features including Quad Cam pawls,
These units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.16, AS 1418.2 and SANS 1594.
The PROCB with overload protection is DNV GL Verification tested according to NORSOK R-002. Our patented Quad Cam Pawl System guarantees permanent engagement of at least one of the two reciprocating cam pawls fitted to the PROCB, ensuring the pawl only just clears the ratchet wheel, with the minimum of clearance as required under BS 4898:1973. But most importantly, in the unlikely event of a pawl spring failure, this design will ensure the brake is still fully functional and the load is sustained without damage to the mechanism. Key design features such as our patented brake pawls and deep pocket design hand wheel along with the full and comprehensive testing regime we have submitted our PROCB hoist to provide the evidence that allows us to state that these units can be safely used for “fleeting”, “drifting” and “crosshauling” applications up to 45° from the vertical without deration.
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. 2
“Guidance notes for offshore lever hoists”, the SS19 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. Tiger Hoists fitted with overload limiters comply fully with NORSOK R-002. The SS19 includes our unique rotational inertia driven torsion switch brake and freewheeling system. This brake system was designed by our 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. The SS19 range of lever hoists incorporates our latest developments and enhancements. Tiger hoisting products are available with either an embedded Supra Digital Chip or an attached digital SupraTag. This allows access through the RiConnect system to digitalised product information such as certification, pre-use check lists and instruction guides.

Tiger uses an 8 point multi start thread pinion shaft which has also increased brake reaction times.
