Crawler Crane is generally expressed as QUY in China.  However, in order to keep in line with international standards, SANY's cranes use English naming rules. Its crawler crane is codenamed SCC (the English initials of SANY Crawler Crane).  The main features of the crawler crane are: its driving cab and lifting control room are combined into one, large ground area, low average pressure on the ground, good stability, and can operate on soft and muddy ground; high traction coefficient, good climbing ability.The slope is large and can be driven on rugged sites; however, the crawler crane travels slowly and damages the road surface during the driving process. Therefore, it needs to be transported by a flatbed trailer during transfer operations.With its performance, productivity and comfort features for operators, operators can work efficiently for longer periods of time with less fatigue.
