The William Hackett dual speed chain hoist is manufactured in accordance with EN13157 which requires that it can be used within an operating temperature range of -40C to +55C.
Light Load Capability: the dual speed chain hoist is tested and certified at 2% of the chain hoist rated capacity.
Twin Pawl: double safety; fitted as standard.
Safety Latches: the dual speed chain hoist top and bottom hooks are fitted with heavy duty cast steel latches.
The latch and hook tip are integrated creating a strong and robust hook closure.
Overload Indicator Marks: the dual speed chain block top and bottom hooks have, as part of the hook forging, overload indicator marks either side of the hook throat.
By measuring the distance between the indicator marks, the hook can be quickly and easily checked to see if any stretch has occurred due to misuse or overloading.
British Standard BS EN13157:2004 + AI:2009.
