Red Net Moment January 27 news (correspondent Kang Qineng) On January 27, Sany Heavy Industry Kunshan Industrial Park No. 6 plant, Sany's first 300-ton electric drive shovel super large digging - SY2600E officially rolled off the production line. This is the crawler excavator product with the largest tonnage of Sany Heavy Industry at present, and once again achieves a technological breakthrough in the field of super-large excavation.
This SY2600E excavator is 15 meters long, 8 meters high, and about three stories high. It has an 8-pump and 3-valve fully electronic control system, the digging bucket capacity reaches 15 cubic meters, and a shovel can dig up about 20 tons of earth and stone. Chen Jiayuan, chairman of Sany Heavy Industry Heavy Machinery Division, said: "In 2008, Sany developed China's first '200-ton hydraulic crawler excavator', successfully filling the domestic gap; 14 years later, SY2600E rolled off the production line, marking a new step in the research and development and manufacturing of large excavators. ”
According to reports, SY2600E inherits the quality and technology accumulation and precipitation of large-scale excavation for many years, mainly for large-scale open-pit mines and earthworks to provide new products for earthwork stripping, ore mining and installation development, which is a new breakthrough of "electric drive + positive shovel", with low energy consumption, large loading, high reliability, comfort and other characteristics.
In terms of energy saving, the product adopts advanced fully electronic control closed core hydraulic system, dynamic response is faster, pressure loss is smaller; at the same time, through the use of 6000V, 900kW high-power motor, long-life reinforced structural parts and four-wheel belt, the whole machine life is longer, the performance is more reliable; in addition, the product is equipped with automatic lubrication system, centralized filling system, etc., the maintenance parts are designed centrally, and the overall maintenance is convenient.
Chen Jiayuan revealed that in the future, SY2600E will be promoted to the global mining market, and the Sany big digging team will continue to strive for the research and development goal of 400 tons and even 800 tons of large excavators, and contribute to China's large excavator equipment manufacturing industry.
According to authoritative data, in 2020, Sany sold a total of 98,705 excavators, accounting for 15% of the global excavator market, and won the global sales championship for the first time on behalf of Chinese enterprises.
