Tiger Corrosions Resistant Manual Hand Chain Hoist
SS12 Series - Sub sea Manual Chain Block
Capacities - 0.5t to 20t Swl
The Tiger SS12 manual hoist is manufactured from the highest quality steel materials available, offering a lightweight, compact and rugged construction, producing an exceptionally strong product resistance to impact damage. With the added advantages of having been fully protected against corrosion using Tigers OCP “Organic Corrosion Protection” formula that gives over 1000 hours continuous protection under ASTM B117 Salt spray conditions.
The exceptional short head room allows for easy installation where every centimetre must be achieved. Using only the highest quality materials precisely machined in our own factory, the SS12 manual hoist is the ideal chain block for salt water use with less maintenance and servicing costs.
These hoist units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.16, AS1418.2 and SANS 1594.

Each hoist unit comes fully certified with a test certificate or an EC Declaration of Conformity stating compliance with the essential health and safety requirements of the Machinery Directive 2006/42/EC. This document clearly states the proof test at 1.5 times the rated capacity and the light load test of 2% of the rated capacity, which exceeds the requirements of the current applicable standards.
The highly efficient twin pawl brake works instantly when operation of the hoist unit is stopped and securely holds the load. Loads are lowered under perfect control, allowing for precise operations. The SS12 Tiger Lifting manual chain hoist passes easily the "brake lock out test" as per BS 3243 with a 5% load of the rated capacity.
Double Cover Protection:
Both the hand chain wheel cover and the ratchet brake cover of this manual chain hoist are designed to offer protection to the brake chamber in the most arduous environments.
Lifting at Angles:
The TCB range of manual chain hoists have undergone a full and comprehensive testing regime that was drawn up by industry specialists and Tiger’s mechanical engineers to provide evidence that these hoist units can be safely used for “fleeting” and “cross-hauling” applications up to 45°.
All such operations should be carried out in accordance with the manufacturer’s instructions and fully risk assessed by a competent person.
Tiger only use the highest quality alloy, calibrated load chains in Grade 80 (T) or 100 (V) on their SS12 range of hoist units. All capacities are available with stainless steel load chain as an option.
Drop forged and heat treated alloy load 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 in house maintenance scheulde. Recessed forgings offer full protection to the load chain anchor bolts on all our bottom load hooks.
The SS12 has OCP protection on all the internal parts including load and hand chain ensuring over 1000 hours continuous protection.
The SS12 is finished in our high quality white Akzo Nobel powder coat paint offering excellent additional corrosion protection. (Data sheets available on request)
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
High performance premium quality grease allows the SS12 chain block to be certified for use within a temperature range of -40°C to +50°C, far exceeding the requirements of current standards.
Chain end stops:
The chain end stops fitted as standard will hold a load of at least 2.5 times the rated capacity when supporting the full load without restraint from other components e.g. brake or gearing. This prevents accidents, by acting as a stop when the lift length of the load chain is exceeded when lowered.
All major components are heat treated and precisely machined to ensure long term smooth operation. High gear ratios keep physical effort to a minimum.
The SS12 tiger chain hoist can be easily converted to have Over Load Limiters fitted. The top hook can be replaced by a competent person so the SS12 manual chain hoist can be directly fitted to our beam trolley range of the equivalent capacity achieving the lowest possible headroom.
The SS12 manual chain hoist has undergone a full test program 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 on every hoist
- Proof loading at 1.5 times the rated capacity
- Light load testing at maximum of 2% rated capacity
The SS12 Tiger chain hoist is finished in our high quality powder coat paint offering excellent corrosion protection.
