Mine Trailers

SmithCo has expanded its large range of on-highway trailers into the Mining industry with off-road trailers in the 50 to 100 ton range (doubles are available also). Haul trucks own the mining industry but they’re expensive, they need hard surface maintained haul roads and they are not suited for distance hauls. Whether you’re grubbing, taking off overburden or need to move ore from remote sites to a central processing plant SmithCo has the side-dump trailer for your application. Besides the conventional side-dump style trailers, tipper style trailers are available also.
