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.

principle bulldozers

Roller is a construction machinery. DRUM use rolling action of soil, roadbed and road pavements dense cushion of self-compacting machinery. Widely used in roads, embankments and dams and other projects.

bulldozer performance

The use of a torque converter and power shift combination of hydraulic mechanical transmission, a continuously variable transmission with automatic torque converter,swamp hydraulic crawler dozer the ability to adapt to changes in load, and automatically shift, reducing shift times, manipulate lightweight and flexible, so that bulldozers operating efficiency.
