Non-excavated working faces for explosion-proof coal mines and suitable for explosion-proof with type II explosion-proof with class ⅡA, ⅡB, Ⅱc, and the temperature group of T1-T4 groups of flammable gases or explosive gas mixtures composed of steam and air can be used. Explosion -proof electric gourd.

Explosion -proof electric gourds are divided into three -level explosion -proof and four -level explosion -proof. Single -air explosion -proof electric gourds are suitable for the flammable lifting of flammable in the factory 1, explosive mixture formed by steam and air; When there is an explosive mixture formed by the flammable gases, steam and air in the factory 1, it is installed on the track of the steel steel rail, and can be moved along the track and the curve to ensure that it is safe enough.

The test temperature of explosion-proof electric gourds is -20 ~+40 ° C, below 1000m above sea level, and relative humidity is 85%(20 ± 5 ° C). Explosion -proof electric gourd has a strong structure, a small weight, a small volume, and a large lifting ability. When the factory is full of explosive mixtures, under the premise of ensuring safety, it is a powerful tool for improving labor conditions and increasing labor productivity. Therefore, it becomes a reasonable process process. The necessary mechanical equipment.
