D410

D410 bulldozer is developed in view of the international development trends of crawler bulldozers. It is newly developed product up to international advanced level. The VSD410 bulldozer features reasonable mechanism, optimum power match, beautiful design, and labor-saving control. Moreover, it makes use of hydraulic rotary transmission, with good performance and high reliability. A The basic model VSD410 bulldozer is created through exclusively introducing the design and technology of Komatsu D355A-3 bulldozer from Japan, and is licensed by Komatsu laboratory. The processing, installation and debugging of the D410 bulldozer are performed in strict technical standards of Komatsu laboratory. Moreover, the bulldozer passed the performance and quality acceptance inspection by Komatsu laboratory. Over long term exchange and cooperation with Komatsu of Japan, we at VOSTOSUN have greatly advanced technologies in producing our D410 bulldozers. Furthermore, our D410 bulldozer was once honored as Chinese brand products of mechanical industry.

Technological Advantages of D410 Bulldozer

 
1. Application of frontier control technique makes the bulldozer have the following advantages. a. Small operating force, high control precision, reduction of labor intensity for the driver, and high working efficiency. b. High mountability, and flexible arrangement of the machine parts.
2. The working hydraulic system makes use of energy-saving technology, and has the advantages as follows. a. Small heat loss. When the operating handle is in the holding position, all oil contained will be discharged to keep the valve pressure loss below0.5Mpa. When the operating handle is in operating position, work will be reduced so as to lower heat loss. b. The hydro cylinders of the bulldozer can move synchronously, free of interference of each other.
3. The electronic monitor is to monitor the parameters such as charging voltage of the engine, fuel level, water level, oil pressure, torque converter oil temperature, hydraulic fluid temperature, filter clog warning, and more. If there is any abnormal parameters, the instrument panel, supervisory lamp, and alarm buzzer, etc. of the monitoring device will give an alarm, increasing reliability and safety of operation of the bulldozer.
4. The bulldozer is designed with new resilient shock absorbing trolley instead of the traditional rigid thrust wheel. Test results show that the viscoelastic suspension mechanism, which has lifetime longer than 4,000h, helps to reduce 50% vibration, and improve efficiency by 30%. Technical Data
