We offer all kinds of non-sparking lifting chain hoist(also called chain block)with trolley,ratchet lever hoist,which used in safety lifting workplace ,such as oil,gas,oilfield,petroleum industries etc.
Non-sparking lifting chain hoist block are made of Aluminum-Bronze (AlBr) or Copper-Beryllium (CuBe). These alloys are specifically designed to eliminate the risk of sparks at sites where explosive atmospheres may be present. Explosive atmospheres are classified by Ex Zones where hazardous, flammable or combustible vapors, liquids, dusts or residues may be present.
Non-sparking lifting chain hoist block, also known as spark resistant chain hoist block, comply with ATEX directives for Ex Zones 0, 1 and 2 (Flammable Gas, Mists or Vapors); Zones 20, 21 and 22 (Combustible Dusts); and M1 and M2 for mining. Our non-sparking hand tools are etched with the Ex Zone classification into them, thereby indicating in which zones the tool can be used.
There are 2 kinds of non-sparking materials available:
1. Be-Cu: Beryllium Copper (Best material for Non Sparking Non-Magnetic Tools, the very highest quality);
2. Al-Cu: Aluminium Bronze (Economic material for Non Sparking Tools, still excellent).
