SWD220Y Crawler Bulldozers' Advantages
1 Powerful Cummins engine features strong power and high efficiency and energy-saving.
2 The high-reliability power shift transmission, stable hydraulic torque converter, and two-stage spur gear final drive feature high power transmission efficiency.
3 The engine can run normally and reliably under all load conditions and all hot environments required by the user, without overheating.
4 With Komatsu technology,the full box-type main frame with application of high performance materials and high strength castings features high carrying capacity against impact load and bending moment and the high quality welds guarantee the life cycle of the main frame.
5 The semi-rigid suspension traveling system increases the ground area of tracks and improves the traction force of vehicle.
