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.
Drop forged adaptor maintaining maximum strength. 360° Rotation and 180° Pivot for Maximum Flexibility. Tested and certified to 4:1 factor of safety.
Self-locking (safety) hook, clevis shackle, reevable egg (master) link or sling hook fittings available.
The highly efficient independent 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 easily passes 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°.
All such operations should be carried out in accordance with manufacturer’s instructions and fully risk assessed by a competent person. Hand wheel: For chain blocks to be used up to an angle of 45 degrees, it’s critical that the hand chain leaves and enters the hand wheel without twisting, snagging or jamming. Thanks to our specially designed deep-profile chain block hand wheel this is achievable as it helps to seat the chain no matter what angle or direction of pull.
Tiger only use the highest quality alloy, calibrated load chains in Grade 80 (T) or 100 (V) conforming to EN818-7 and ISO 16872. Our hoists are also available with stainless steel load chain.
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.
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. 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.
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.
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.
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
The TCB is finished in our high quality powder coat paint offering excellent corrosion protection.
Optional Chain Carrier
Strong and contoured chain end anchor will hold a load of at lest 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 action as a stop when the lift length of the load chain is exceeded when lowered.
