Tiedou excavator recommendation: Sumitomo SH series medium and large excavators (second phase)

　　In the previous issue, Tiedou briefly introduced the basic parameters and specifications of Sumitomo SH series excavators below medium size. Sumitomo's 20-ton or above models are the main models of existing excavators. For enterprises or large-scale engineering projects, 20 tons is only the basic demand, and 30 tons or even 40 tons are the main models. Sumitomo's new -6 series of large-scale equipment still uses Japanese original Isuzu engines as power output. (SSC) is used to optimize fuel economy to systematically optimize the excavator's work types under different conditions to improve efficiency.

　　Compared with the Sumitomo SH-5 series excavators, Sumitomo has an overall overall performance improvement of more than 4%, especially for the excavator micro-operation Sumitomo has a significant improvement. Sumitomo SH-6 still uses fuel injection optimization common rail high-pressure fuel injection technology. Further improvements have been made to waste recycling (EGR) and so on. Achieving the perfect blend of work performance under low fuel consumption.

　　Sumitomo's three types of working modes are designed for different working environments, especially for different working requirements in different areas. These three modes can improve work efficiency and have a more effective balance in fuel consumption. The intelligent operation modes of SP (Super Power), H (Heavy), which is most suitable for heavy-duty operations, and A (Auto), which is suitable for a wide range of operations, allow users to easily cope with challenges.
