explosion proof electric chain hoist

Short Description:

Operating in explosive atmospheres means there are different needs for lifting equipment, ranging from standard products to highly advanced cranes. Because of this, we have manufactured our products to be optimized for your specific and often unique lifting requirements. All crane components are selected to improve the high level of safety required for the hazardous atmospheres in chemical and petrochemical plants, oil refineries, gas power plants, wastewater treatment plants, paint shops and other industrial sites.

The “Explosion Proof” term defines the electrical enclosures, controls, motors and wiring requirements required to contain any spark or arcing from penetrating the confines of the enclosure and potentially igniting the combustible material present in the atmosphere.
LIFTHAND Explosion Proof Classifications for Equipment (Class, Group & Division)
Class I - Locations: Are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.
Class II - Locations: Are those in which are hazardous due to the presence of combustible
Class III - Locations: Are those which are hazardous due to the presence of easily ignitable fibers or flyings, but in which such fibers or flyings are not likely to be in suspension in the air in quantities to produce ignitable mixtures.
Groups for Class I (above)
Group A - Atmospheres containing acetylene.
Group B - Atmospheres containing hydrogen, or gases (or vapors) of equivalent hazard, such as manufactured gas.
Group C - Atmospheres containing ethyl-ether vapors, ethylene or cyclo propane.
