The Final Coal Mine in Japan
Explosion-proof Electric Chain Hoists Used in the Last Coal Mine in Japan
Because it is difficult to transport large machines such as drum cutters (coal mining machines) and road headers (rock board excavators) in the narrow spaces of coal mines, they have to be transported as parts and later assembled at the mining site. Our ultra-low-headroom, Explosion-proof Electric Chain Hoists specially made for coal mining is used to transport machine parts to the work site.
By adopting our Explosion-proof Electric Chain Hoists specially made for coal mining applications, even if the gas that naturally exists in a coal mine gets inside the hoist and ignites in reaction to sparks generated in the electrical equipment, the explosion will be safely kept inside the chain hoist. In addition, we adopted a short head shape with little headroom so that the size of the chain hoist would not become an impediment to work even in this narrow space.
* We currently do not manufacture or sell electric chain hoists designed for coal mines.
