At 8:18 a.m. on January 27th, in the No. 6 workshop of Kunshan Industrial Park, Sanyi 300-ton electric-drive front shovel super digging-SY2600E officially rolled off the production line. This is currently Sany's largest crawler excavator product, which once again achieves a technological breakthrough in the field of ultra-large excavation.

Chen Jiayuan, Chairman of Sany Heavy Machinery, Wang Zheng, General Manager of Sany Heavy Machinery, Li Lianwen, General Manager of Sany Heavy Machinery Marketing Company, Cao Donghui, Deputy Chief Engineer of Sany Heavy Machinery and Dean of the Great Excavation Research Institute, and project related personnel attended the event. Witness this milestone moment together.

This SY2600E is 15 meters long and 8 meters high, about three stories high. It has an 8-pump 3-valve fully electronic control system, a bucket capacity of 15 cubic meters, and a shovel can dig up about 20 tons of earth and stone.

Chen Jiayuan said: "In 2008, we developed China's first '200-ton hydraulic crawler excavator', which successfully filled the gap in China; 14 years later, the SY2600E is off the assembly line, marking the first in the development of large excavators, The field of manufacturing has reached a new level.”

According to reports, SY2600E has inherited the quality and technical accumulation of Daquan for many years. It mainly provides new products developed for earthwork stripping and ore mining and loading for large-scale open-pit mines and earthwork projects. It is a new breakthrough in "electric drive + front shovel" and has low energy consumption. , large load, high reliability, comfort and other characteristics.

In terms of energy saving, the product adopts an advanced fully electronically controlled closed-center hydraulic system, which has faster dynamic response and lower pressure loss. The machine has a longer service life and more reliable performance; in addition, the product is equipped with an automatic lubrication system, a centralized filling system, etc., and the maintenance parts are centrally designed, and the overall maintenance is convenient.

Chen Jiayuan said, "In the future, the SY2600E product will be introduced to the global mining market, and the Sanyi 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. Make a contribution." (For reprint, please indicate www.seetao.com) See the editor of the engineering column of Tao.com/Wang Xia
