Thunderbird has designed electric chain hoists with explosion-proof capabilities to ensure their safe use in hazardous work environments such as those containing flammable gas or chemicals. These environments require robust electrical components like motors and control systems to be properly protected from detonatable surrounding atmospheres. Heavy oil and gas, as well as chemical processing industries, often utilize such equipment. Like other electric hoists, explosion proof chain hoists have variables like speed control and overload protection to maintain lifting efficiency within dangerous environments.
