Product Description

SWD320Y Bulldozer Advantages
 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. Use automatic dust discharge type air precleaner for more adaptable in working in dust surroundings.
Gear Box   
This machine is equipped with transmission of planetary gear and rotary lockup multi-disc clutch hydraulically engaged and force lubricated. Forward 3 speeds and reverse 3 speeds can be gained by actuating hydraulic control valve.
Torque Converter   
Hydraulic torque converter is a newly developed product with the improvement made to the material, process and layout based on introduced advanced international technology. It features simple archite cture, easy maintenance, low noise, excellent reliability. 
Torque converter is of 3-element, 1-stage, 1-phase, centripetal turbine type with simple structure but good technology. It provides high power efficiency, great penetration, big capacity and less loss when the turbine idles.
The Final Driving   
We master the technology in the manufacturing tip relief, crowned gear which features heavy load capacity, stable drive and long life.
