High Quality Crawler Bulldozer SD16/SD13/SD22 In Stock
The double pump confluence system with unloading function can automatically or manually switch over the individual pump based on the working condition and unload the high pressure by auxiliary pump, featuring high intelligence and energy-saving.
The Factory's independently developed load-sensing system features smooth digging and loading combination motions, low motion changeover impact, and high efficiency and energy-saving.
During the digging and loading combination operations, the engine power to the drive system can be easily cut off so that all power is supplied to the hydraulic system to improve the digging and loading efficiency.
The machine automatically switches to two-wheel drive mode while traveling in gear IV to eliminate the parasitic power loss.
