HOISTING
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
PROCB, 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 doubles
the lead distance compared with typical 4 point threaded shafts, increasing
the brake efficiency by 100%.
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 PROCB with overload protection is DNV GL Verification tested
according to NORSOK R-002.
