Ripper Bulldozer (SD8N Bulldozer)
by
ramsingh
Ripper Bulldozers are used in land clearing operations where heavily compacted soil or frozen ground must be separated, allowing easier grading and dozing to take place. The steel shanks penetrate the surface of the soil to break and loosen it, enabling the bulldozer blade to move the soil.
SD8N bulldozer is track-type dozer with elevated sprocket, hydraulic direct drive, semi-rigid suspended and pilot hydraulic controls. Equipped with hydraulic-mechanic type torque converter, planetary, power shift transmission. It can be used in road building, hydro-electric construction, land clearance, port and mine development
