Tiger "TCB" Manual Chain Hoist, Top Hook Suspended - Range from 500kg to 30 tonnes
Hook Suspension Manual Chain Block. Can be safely used for “fleeting” and “cross-hauling” applications up to 45°
The TCB is manufactured from the highest quality steel materials, offering a lightweight, compact and rugged construction, producing an exceptionally strong product resistant to impact damage. 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 TCB is the ideal block for long term use with less maintenance and servicing costs. These units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.16, AS1418.2 and SANS 1594. The current TCB11 model is being superseded by the TCB14, retaining all the current features plus additional enhancements, as it becomes available.
Each 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 standard.

The highly efficient 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 TCB 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 are designed to offer protection to the brake chamber in the harshest environments from foreign objects.
Lifting at Angles
The TCB range of chain blocks has undergone a full and comprehensive testing regime that was drawn up by industry specialists and Tiger’s mechanical engineers to provide evidence that these units can be safely used for “fleeting” and “cross-hauling” applications up to 45°. Note: All such operations should be carried out in accordance with 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). Also available with stainless steel load chain.
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.
High performance premium quality grease allows the TCB Blocks 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:
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 TCB can be easily converted to have Load Limiters fitted. The top hook can be replaced by a competent person so the TCB11 can be directly fitted to our beam trolley range of the equivalent capacity achieving the lowest possible headroom.
The TCB 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 TCB is finished in our high quality powder coat paint offering excellent corrosion protection.

Traditional Tiger Hooks
Tiger Hooks with new "EZ Check" 3 point marking system
Newer models of the TCB are fitted with the patent pending Tiger “EZ check” 3 point marking system. With this system a quick check that the A and B measurements are the same (as shown in the diagram below) will indicate if the hooks have stretched If A≦B the hook is fine; If A>B the hook needs to be replaced:
