In construction operations on mountainous roads, where the terrain is undulating and road conditions are complex and harsh, machinery is put to an extreme test in terms of power and traction. The SG15 - B6 grader, however, with its formidable traction force, effortlessly pushes through piles of earth and stones blocking its path. Even when encountering areas with a mix of hard rock layers and compacted soil, it shows no sign of hesitation. Its tracks firmly grip the ground, and the engine speed remains almost constant, continuously delivering robust power to clear obstacles and pave the way for subsequent road leveling work.
