Explosion -proof electric gourd cranes have electrical conduction and mechanical friction when they are running, and sometimes arcs, sparks and overheating may also produce arcs, sparks, and overheating. Therefore, the explosion -proof starting machines used in some flammable and explosive places should take relevant measures: prevent arc, sparks, or overheating; even if it is generated, it cannot ignite some of the relevant explosives around. The starting point of the explosion -proof and explosion -proof heavy aircraft is when the design and manufacturing of explosion -proof starting machines. Explosion -proof starting machine is a complete mechanical and electrical equipment composed of explosion -proof electrical equipment, metal structures, mechanisms and components, explosion -proof electrical intervertebral connection, mechanical or hydraulic transmission, and safety installations. Therefore, on the one hand, the explosion -proof and explosion -proof requirements should consider the high temperature and sparks generated by a single explosion -proof electrical equipment. On the other hand, the mechanical spark and high temperature generated by the impact of the friction impact of mechanical motion components should also be considered. The basic explosion -proof principle of explosion -proof and heavy machines should take some relevant measures. It must be controlled to a certain extent. The use of the corresponding explosion -proof technology to control and eliminate the electrical spark and mechanical sparks, so that it can not ignite other other burning other. The explosive gas mixture in the environmental area, under general, can be summarized as electrical explosion -proof technology and mechanical explosion -proof technology in the relevant explosion -proof techniques of explosion -proof starting machines.

As a special lifting equipment, explosion -proof cranes have been applied to chemicals, which are related to chemicals and are related to explosive mixtures. Because of the danger of the relevant environment of special equipment and the particularity of the work, our country has implemented a more compulsory relevant regulatory mechanism for special equipment. To a certain extent, this can not only ensure the property of the people and the safety of life, but also promote the development of the national economy. In order to effectively improve the related production efficiency in some flammable and explosive related dangerous places, some flammable and explosive -related dangerous places have played a more important role in reducing the intensity of operations to a certain extent.
