These are intermediate machines, situated between trucks used on roads and rigid dumpers. (see below) They have 3 or 4 axles. The two rear axles, which are drive axles, are mounted with single or twinned tyres. The front axle or axles, mounted as singles, are essentially steering axles but can sometimes also be drive.
The term coal quality is used to distinguish the range of different commercial steam coals that are produced directly by mining or are produced by coal cleaning. Generally, coal quality for steam coals (i.e., coal used for electricity generation) refers to differences in heating value and sulfur content (Table 4.2), although other.
