Ex proof cranes are used in spaces where there is a risk of explosion due to flamable gases or dusts using chemical processing, or oil and gas production. Explosive proof cranes or ex proof cranes are used in safely operating environments mechanically preventing sparks from being generated. Ex proof cranes are needed in chemical processes or mining as they are vital in lifting difficult to manage cranes while ensuring the safety of people and equipment. Parts of these cranes such as the casing of ex proof cranes are put under mechanical shielding ensuring them from explosion saving equipment in these dangerous worlds.
