bulldozers life

Steel wheel roller DRUM construction bright grind,swamp crawler bulldozer with blade grind and sheep-foot roller grooves and the like. Light grind most common, mainly for pavement compaction, especially triaxial three Roller (see pictures). Compaction can concentrate on the protruding portion, compaction flatness, suitable for asphalt compaction. Axle arranged by uniaxial single wheel, dual-axis wheel, biaxial and triaxial three and so on three species.
Hydrostatic roller mechanically own gravity, so be compacted and dense layer of permanent deformation. It is divided into two types of steel wheel and tire.
