People's Daily Online, Changsha, September 19 (Reporter Cao Chang, Hu Weiqin) Today, in Sany Industrial City, Hunan, China, the 86-meter 9-bridge 7-section boom independently developed by Sany Heavy IndustryPump trucksIt successfully rolled off the assembly line, once again breaking the world record of 72 meters in the world * long boom pump truck set in 2009.

The reporter learned that the 86-meter pump truck has achieved three worlds - the boom is long, the number of boom sections is more, and the pumping displacement is 5655. For the first time, the pump truck adopts the design of 7 arms, and the construction range is wider and more flexible than that of 5 and 6 arms. At the same time, it also innovated the heat treatment process and independently developed the 1200MPa high-strength steel plate, which solved the problem of large deformation and low impact toughness of the high-strength steel plate of the boom, and formed a unique competitiveness; The pumping capacity has also been increased from 230 m3/h to 240 m3/h, setting a new world record for pumping displacement.

Not only that, the pump truck has also developed a 9-axle all-road chassis with completely independent intellectual property rights, equipped with a number of advanced intelligent control technologies, and realized 100% self-made of the main critical parts. "The birth of the 86-meter pump truck is the *5654 interpretation of Sany's 'breaking fear and bold innovation', marking a new milestone in the design and manufacturing technology of the pump truck." Tang Xiuguo, president of Sany Group, said.

Liang Wengen, chairman of Sany Heavy Industry, said at the off-line ceremony that for a long time, China's pump truck boom technology was controlled by others, and Sany finally mastered this core technology in 1999 through arduous independent research and development and innovation, breaking the monopoly of foreign brands. "From 66 meters, 72 meters, to today's 86 meters of pump trucks, we have stood at the forefront of the world's pump truck manufacturing field again and again, from the technology 'follower' to the industry's 'leader'."

It is reported that at present, the 86-meter pump truck has applied for more than 180 national patents, and 36 have been authorized.
