The high reliability power shift transmission, the stable hydraulic torque converter, and two-stage spur gear final drive feature high power transmission capacity and efficiency and high productivity.
Â
The independent engine water tank, the chassis oil cooler, and the water-air intercooler integrated in the Chongfa engine provide prominent cooling performance and simple maintenance operations to guarantee the continuous working of the machine.
Â
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 to support the continuous high-strength working of machine under severe working condition and the high quality welds guarantee the life cycle of the main frame.
Â
The low-drive final drive can provide powerful drive force and efficient gradeability. Shantui's crawler chassis has reached the international advanced level in process level and can adapt to various complicated working conditions, featuring high reliability and carrying capacity.
Â
The standard straight tilting blade features powerful cutting force and the single-shank and three-shank rippers of adjustable penetrating angle can be used for the ripping of clay and frozen earth as well as the stripping of hard working faces, such as gravel and hardened salt mine.
