    Certification:

    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.

    Adaptor Components:

    Drop forged adaptor maintaining maximum strength. 360° Rotation and 180° Pivot for Maximum Flexibility. Tested and certified to 4:1 factor of safety.

    Adaptor Components

    Self-locking (safety) hook, clevis shackle, reevable egg (master) link or sling hook fittings available.

    Safety Brake:

    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.

    Load Chains:

    Tiger only use the highest quality alloy, calibrated load chains in Grade 80 (T) or 100 (V) conforming to EN818-7 and ISO 16872. Also available with stainless steel load chain.

    Hooks:

    Our hooks incorporate our latest Patent Pending (GB1420387.1) “EZ Check” feature which allows operators and inspection engineers to easily check to see if the hoist has been previously overloaded or shock loaded by simply measuring between the triangle of pop marks (see page 10).

    Our drop forged and heat treated alloy hooks are furnished with heavy duty spring latch kits that fully engage into the recessed nose of the hook safeguarding the load when side loading of the latch occurs and 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. The entire hook fitting has been protected using OCP or stainless steel fixtures and fittings.

    Recessed forgings offer full protection to the load chain anchor bolts on all our bottom hooks. 

    Grease:

    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.

    Mechanical Efficiency:

    All major components are heat treated and precisely machined to ensure long term smooth operation. High gear ratios keep physical effort to a minimum.

    Convertibility:

    The TCB can be easily converted to have Load Limiters fitted. The top hook can be replaced by a competent person so the TCB can be directly fitted to our beam trolley range of the equivalent capacity achieving the lowest possible headroom.

    Overload protection:

    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 in the chain wheel will slip, allowing the hand wheel to be rotated whilst not engaging the gear box. This prevents further lifting of the load, though lowering is still possible.

    Performance:

    The TCB has undergone a full test program that includes:

    Type Testing

    • 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

    Finish:

    The TCB is finished in our high quality powder coat paint offering excellent corrosion protection.
