Tiger "SS12" Sub-sea (Underwater) Corrosion Resistant Chain Block Range from 500kg to 20,000kg
Manufacturing Standard: BS EN 13157:2004, ASME B30.16-2007
Hand chain hoist designed specifically for under-water (sub-sea) use, though also probably one of the safest chain hoists for heavy industrial use.
The Tiger "SS12 Sub-Sea Chain Hoist" is perfect for underwater use but can also be used above ground if needed, it comes with the added advantage of having been fully protected against corrosion using Tiger’s OCP “Organic Corrosion Protection” formula that gives over 1000 hours continuous protection under. ASTM B117 Salt spray conditions. The Hoist is manufactured to be lightweight and portable, with a rugged steel body and heat treated alloy hooks.
Can also be supplied Atex Approved.

The superb low head room allows for easy installation where every millimetre is precise. Using only the highest quality components expertly machined in fabrication, the SS12 is the ideal chain block for salt water use with less maintenence costs. These units meet and exceed all the requirements within BS EN 13157:2004 & ASME B30.16-2007.
The SS12 with OCP protection on all the internal parts including load and hand chains ensuring over 1000 hours continuous protection.
Double Cover Protection:
Both the hand chain wheel cover and the ratchet brake cover are designed to offer protection to the brake chamber in the harshest environments from foreign objects.
The highly efficient and fully corrosion protected twin pawl brake works instantly when the operation is stopped and securely holds the load. Loads are lowered under perfect control, allowing for precise operations. The SS12 easily passes the “brake lock out test” as per BS 3243:1990 with a 2% load of the rated capacity.
Tiger only use the highest quality alloy, calibrated load chains in Grade 80 (T) or 100 (V). These chains have been protected using OCP protection without any loss of mechanical performance. The SS12 comes as 3.0mtr HOL as standard but can be chained up to whatever length is required. Stainless steel load chain available on request for certain capacities.
Drop forged and heat treated alloy hooks are furnished with heavy duty latch kits that fully engage into the nose of the hook offering maximum load security. The swivel hooks are attached to the yoke using high grade nuts & bolts allowing for complete inspection during any statutory inspection or written scheme maintenance. Recessed forgings offer full protection to the load chain anchor bolts on all our bottom hooks. The entire hook fitting has been protected using OCP or Stainless steel fixtures and fittings.
Marine Friction Discs:
Developed and designed for Subsea use creating a highly efficient, reliable braking surface for use in the most extreme conditions.
The SS12 is finished in our high quality white Akzo Nobel powder coat paint offering excellent additional corrosion protection. (Data sheets available on request)
High Performance Premium Grease:
Load carrying ability, mechanical stability, corrosion protection, water resistance and increased operating temperature ranges are all improved by the using only the very best lubricant.
All major components are heat treated and precisely machined to ensure long term smooth operation. High gear ratios keep physical effort to a minimum whilst complying to all the relevant standards.
All our SS12 chain blocks are available with chain bags on request to fit the exact amount of chain specified.Designed to carry and hold the exact length of load chain required for the operation. Incorporating a stainless steel frame work and heavy duty PVC flexible bag reinforced by webbing with eyelet drain holes for an easy transfer through the splash zone. These chain bags prevent loose chain from getting snagged during lifting or lowering operations and protect any loose chain during transit to and from the operational site.
Proof Load Tests:
Every chain block is individually tested to 1.5 times the rated capacity and is light load tested with a maximum load of 2% of the rated capacity then certified stating the Capacity, Serial number, Height of lift with Working Load Limit (WLL), Proof Load (PL) and Light Load Test (LLT)
Overload Protection (load limiter):
As an option, the hoist can be supplied with overload protiection. If the chain block is fitted with a slipping clutch overload mechanism then it is protected from overload. When the load limit is exceeded, the clutch chain wheel will slip, allowing the hand wheel to be rotated whilst not engaging the gear box. This prevents furth lifting of the load, though lowering is still possible.
The SS12 has OCP protection on all the internal parts including load and hand chain ensuring over 1000 hours continuous protection.
The SS12 has undergone a full test programme that includes:
- Ultimate strength test, at least 4 times the Working Load Limit (WLL).
- Continuous cyclic testing of over 1500 cycles.
- Chain end anchorage test, passing at least 2.5 times the WLL without any restriction of the brake or gears.
Test of every hoist
- Proof loading at 1.5 times the rated capacity.
- Light load testing at maximum of 2% rated capacity.
