Depth reading: 86 meters behind the story of the truck (Figure)

Trinity 86 meters pump truck 86 meters, continue to write the myth of Trinity. This pump body, every screw, every inch of steel, each tube also unite the Trinity researchers and painstaking efforts to condense to participate in this project each R & D relatives silent support. When SANY's name was once again remembered in the history of the world's construction machinery, these researchers, as behind-the-scenes heroes, were also destined to be remembered in the thriving development of Trinity. The 86-meter pump truck to make great efforts to research and development soldiers a 86-meter pump off the next day, the reporter walked into the Sany Industrial Park R & D building. In a total area of ​​3.3 million square meters of industrial park, this covers an area of ​​just over 10,000 square meters of five-storey white buildings and most of the huge plant compared to some alternative and somewhat mysterious. In the R & D building, everyone is busy and nervous. Meet, call, sitting discussion, speech, a variety of discourse confrontation, integration, one after another. Pumping Division on the third floor to study the hospital pumping station overall, the reporter saw the assistant director Liu Cunyong. He was plainly dressed, dark-skinned, and his workwear apparently had worn for years, often cluttered with dust on his shoes. He is a member of the 86m pump project team. In March of this year, at the very beginning of the project team, Liu Cunyong and other 7, 8 people were arranged in a single office to work together. At that time, the mighty men and women in each of these fields had just handed over their original jobs, and no one knew what they were doing in that small office. Liu Dung-yong slightly pondered a moment after the reporter dared to know and said: "The 86-meter pump truck is the result of many team cooperation in the research and development system and also the sedimentation of our pump design and manufacturing experience in the 30 to 30 years. The team paid a lot for the 86-meter pump truck. "" For the first time, SANY developed a self-made 9-axle all-terrain chassis (the chassis used for the 86-meter truck) completed by the crane research and development team; besides, Independent research and development of key components, such as: 1200MPa high-strength steel, reducer, slewing ring, high performance valve group, transfer case ...... "so many important parts have a common name: SANY. Originally brewing the world's longest jib pump design twists and turns, the project team designed a good 3 sets of programs, and even including the design of super-100 meters jib pump. At that time, on the basis of 72 meters, jib length how many more meters, and not sure. Each set of programs, for different design heights, the project team have carried out careful consideration and completed the calculation of the data, we can say that each set of programs are feasible. However, in the final assessment, for safety reasons, we chose the 86m boom pump the best solution. In fact, Trinity leaders believe that with the "physical reserve" in the research and development of pump trucks for more than 30 years, it is entirely possible to create a record of being taller, more satisfied, and more cowardly. Second, in June 2011, the 86-meter pump truck design plan was finalized and the project team was relieved. However, two more serious problems occurred during the trial production stage: Ensure that all parts, including hundreds of non-standard outsourcing purchased parts in place in time; the second is to ensure that every part of the high quality, zero defect. At this moment, heat waves hit people in southern China. In Changshu, for the 86-meter equipped with 40,000 Nm torque reducer has just been successfully developed; in the Sanyi Industrial Park in Kunshan, a special for the 86-meter pump 7 knuckles are in the orderly manufacturing; in Loudi, Hunan, the same Is a specially designed 450-meter-long oversized main cylinder for a 86-meter pump truck under tension ... The hydraulic system is the source of the pump's power and the fuel tank is the key to the hydraulic system. As a pumping unit research director of the Institute of hydraulic, congratulatory shoulder carry heavy responsibility, responsible for all the 86-meter tanker and the entire hydraulic system development. In this way, He Ji led his team almost entirely at Loudi's manufacturing site. When processing, every cylinder, every process, there are people tracking, quality inspection. Afterwards, all other members of the project team said, "The hydropower-led hydraulic team created the myth that a cylinder normally takes more than 30 days to produce, and they have produced less than 20 days in just two." "Drawings also Not come out, we order some of the structure in advance. Purchasing less than the large-scale steel how to do? At that time to find the steel mills, ingots came out, we on-site rolling. In order to ensure quality, even if the hydraulic system is a pipe , We are all well-tailored, every tubing is touched by hand, "said the congratulatory message. At the same time, in order to ensure the absolute reliability of the 86m boom truck, the safety index in the design has been greatly improved compared with the conventional pump truck: the safety of the boom is increased by 10% and the overall stability of the pump truck is increased by 20%. In addition, the project team also requires the use of more specialized testing equipment, repeated testing of each component. "For example, there is a jib, made in Kunshan off the assembly line, the use of wet powder testing, testing no problem, but to Changsha, and so on, we once again using ultrasonic testing of its welding defects and cracks, the results failed, immediate rework. Project team member Tan Haibo told reporters. Three things are ready, only owe the east wind. August 15, 86 meters truck finally reached the assembly stage. At this stage, in order to solve the problems in the assembly as quickly as possible, the project team members continued to fight, and some even worked 72 hours continuously. Since the hydraulic system was extremely important in the assembly of the entire 86-meter pump truck, HE Cong worked continuously for three days and two nights. On September 19, when a father lying in a hospital bed saw a Trunk and 86-meter pump truck off the assembly line, a rare smile appeared on his face. "He knew that there was also a son's contribution to this world-renowned pump truck." Here, the eyes of the telegram have long been wet. Innovation is like fighting, who pioneers, the use of patents to seize the hills, who have to make strategic advantages. From March to September, when 86-meter pump-driven innovations in this advanced world came to the world in such a short period of time, the outside world had to admire the determination and courage of Trinity R & D personnel to race against time. At 4:00 on August 17, Xiong Jinchang from the pump truck headquarters also fought in the assembly shop to help workers finish the final assembly. When the reporter asked why he stayed at the assembly site so late, Xiong Jinchang said: "In assembly, in the face of new products, workers have confidence if the R & D personnel are there." At this moment, the workers found a leg appeared The retractable can not recover the problem, Xiong Jinchang feeling serious, then immediately reported to the hospital to pump pumping Wang Youyi Dean reported this situation, but considering how long a few days before President Wang did not rest well, and now it is late at night, he Only send a text message to President Wang. But the next day, Xiong Jinchang was scolded: "Why such a big thing do not call to inform me." In order to ensure the smooth assembly, pumping Division to study the leadership of our hospital leaders: Dean Wang Youyi, vice president Chen Tianming accompanied Vice-President Liu Yongdong climbed the arm himself, listening to the tubing has no oil, whether the wrong answer; vice president Tan Lingqun full track, full guidance; overall Liu Cun Yong, Xiong Jinchang, the hydroelectric congratulation continued Working for 72 hours or more, Hedian watched his subordinates work overtime, each time at their own expense to buy supper for colleagues ... ... September 19, in the much anticipated, 86 meters pump stunning debut, won the applause and praise . R & D officers and men in the hearts of tense string but did not relax, the next stage, they will further the world's longest boom pump debugging test until the performance, the data impeccable.
