With the maturest technology introduced, Sinoway offers both flat design track dozers as Komatsu and elevated track bulldozers as Caterpillar. As a supplement, Sinoway provide also wheeled bulldozer for your application which crawler dozers are not allowed. From a wide horsepower range of 80HP to 430HP, with various blade types and attachments available, the last thing now is just selecting the right bulldozer for your application.

The torque converter of SWD320Y is a hydro-mechanical converter whose power is divided outside, which has the characteristics of wide high efficiency range. Steering and braking can be controlled with the same control lever. Braking system utilizes hydraulic boosting structure, which is convenient and labor-saving. The final drive gear has the characteristics of large displacement coefficient value. 
 

Optimal design in overall appearance and structure strength. 
Powerful Cummins engine  adopted for high power rise, big output torque, fuel saving and excellent reliability. 
Hydraulically controlled drive, automatically speed regulating and non-stop gear shifting. 
3-element, single stage, single phase torque converter for higher efficiency and bigger capacity. 
The hexagonal cab offers excellent visibility, the powerful ventilation and unparalleled dust-free. 
The final drive uses triangle Spline and tip relief, crowned gear drive for enhanced balance and the stability during power transmission, and increased life. 
Blade is more durable and capacious. 
Alarming & monitoring system is efficient and reliable. 
Centralized pressure checking easy for malfunction diagnosis. 
Ergonomics design in controls to reduce operator's fatigue. 
se automatic dust discharge type air precleaner for more adaptable in working in dust surroundings.
