TCB Chain Block

The TCB is manufactured from the highest quality steel materials precisely machined in our own factory, offering a lightweight, compact and rugged construction, producing an exceptionally strong product resistant to impact damage.  The especially low headroom allows for easy installation in the most restricted environments. The unique design features - including our patented Quad Cam Pawl System - give it significant safety advantages over standard chain blocks and make the TCB chain block the ideal tool for long term use with low maintenance and servicing costs.

These units meet and exceed all the requirements within BS EN 13157: 2004+A1:2009, ANSI/ASME B30.16, AS 1418.2 and SANS 1594. 

DNV GL Verification tested according to NORSOK R-002

Details

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.

Patent Protected Quad Cam Brake Pawl System:

This patented development in brake efficiency guarantees permanent engagement of at least one of the two reciprocating cam pawls fitted to the TCB, ensuring the pawl only just clears the ratchet wheel, with the minimum of clearance as required under BS 4898:1973. But most importantly, in the unlikely event of a pawl spring failure, this new design will ensure the brake is still fully functional and the load is sustained without damage to the mechanism.

Brake Efficiency:

Tiger uniquely uses an 8 point multi start thread pinion shaft which has measurably increased the efficiency in brake reaction times - up to 50% measurable difference compared with longitudinal 4 point pinion threads.

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 as required in many international standards. This prevents accidents, by acting as a stop when the lift length of the load chain is exceeded when lowered. 

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. The TCB with overload protection is DNV GL Verification tested according to NORSOK R-002.

Safety Brake:

The highly efficient and fully corrosion protected brake system 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 3243:1990 with a 2% load of the rated capacity.

Lifting at Angles:

The TCB range of chain blocks fitted with the patented protected Quad Cam Brake System 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”, “drifting” and “cross-hauling” applications up to 45° from the vertical without deration. Note: All such operations should be carried out in accordance with manufacturer’s instructions and fully risk assessed by a competent person.

With a conventional twin pawl brake mechanism (teardrop design) failure can occur if the pawl spring erodes, fractures or a shock load bounces the pawls out of the ratchet gear. Without the spring these systems rely on gravity keeping the pawls engaged and are flawed when the hoist is used at angles away from the vertical.

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.

Deep Profile Hand Wheel

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 (for units up to 10t capacity).

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.

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.

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.

Chain Carriers:

Available with chain bag as an option.

Entertainment Rigging:

Available in black finish for the entertainment industry.

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.

Finish:

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

Hooks:

Our hooks incorporate our latest Patent Pending “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.

Available with hooks that swivel under the full working load limit, to meet relevant standards i.e. AS 1418.2. Also available with spark resistant hooks.

Forgings:

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

Multi-fall bottom hooks are designed and manufactured to exact tolerances to negate finger traps and twisted chain. 

Combination Trolley and Block:

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. 

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

Due to our policy of continual product development, dimensions, weights and specifications may change without prior notice. Please check with your Tiger sales team when ordering.
