On January 27, Sany Heavy Industry’s first 300 t electric-drive front (face) shovel, SY2600E, officially rolled off the production line in Kunshan Industrial Park in Suzhou, it says “once again achieving a technological breakthrough in the field of super-large excavation.” This is currently Sany’s largest crawler excavator product. Chen Jiayuan, Chairman of Sany Heavy Machinery, Wang Zheng, General Manager of Sany Heavy Machinery, Li Lianwen, General Manager of Sany Heavy Machinery Marketing Co., Ltd., Cao Donghui, Deputy Chief Engineer of Sany Heavy Machinery and Dean of the Great Excavation Research Institute, and project related personnel attended the event
The SY2600E is 15 m long and 8 m high, and about three stories high. It has a fully electronic control system with eight pumps and three valves. The bucket capacity reaches 15 cubic metres, and the shovel bucket can handle about 20 t of ore or overburden. Chen Jiayuan said: “In 2008, we developed China’s first ‘200-ton hydraulic crawler excavator’, which successfully filled the domestic gap; today, 14 years later, the SY2600E is off the assembly line, marking Sany’s research and development in large excavators. The manufacturing field has reached a new level.”
Sany said it is a new breakthrough in ‘electric drive + front shovel’ with low energy consumption, large load, high reliability, operator comfort and other characteristics. In terms of energy saving, the product adopts an advanced fully electronically controlled closed-centre hydraulic system, which has faster dynamic response and lower pressure loss by using a 6,000V, 900kW high-power motor. Thanks to long-life reinforced structural parts and a four-wheel belt chassis, “the machine has a longer life and more reliable performance; in addition, the product is equipped with an automatic lubrication system, a centralised filling system…and the maintenance parts are centrally designed, making the overall maintenance convenient.”
Chen Jiayuan said: “In the future, the SY2600E product will be introduced to the global mining market, and the Sany Heavy Industry excavation team will continue to strive for the research and development goal of 400-ton or even 800-ton large excavators, and contribute to the large-scale excavator equipment manufacturing industry in China.”
