Hunan Science and Technology Award and Innovation Award Conference Held in Changsha
It is reported that this award has for the first time added a Hunan provincial innovation award jointly awarded by the provincial party committee and the provincial government. The award covers the "Science and Technology Innovation Award", "Product Innovation Award", "Culture Innovation Award" and "Management Innovation Award", etc. Four categories, each category reward no more than 10 items. On the website of the Hunan Provincial Government, “The First Innovation Awards in Hunan Province and the List of Objects to be Awardedâ€, the “Highly-Purpose and High-Efficiency 56-meter Concrete Pump Truck†developed by Zoomlion Heavy Industries & Construction Co., Ltd. was listed in the “Product Innovation Awardâ€. "In the first place on the list, in the afternoon of the same day, Liu Quan, supervisor of Zoomlion, and Wu Dezhi, director of Zoomlion Concrete Pumping Research Institute attended the conference and received the award. “This is the crystallization of our R&D team!†Wu Dezhi filled with emotion as he won the award.

The research and development stage is difficult to overcome
According to Wu Dezhi's introduction, in order to meet the needs of customers, Zoomlion launched a 4.0 product upgrade strategy in 2015. Zoomlion Concrete Machinery Co., Ltd. locked the 56m pump truck with the largest market coverage as an upgrade pilot product, and deployed more than 10 core backbones in the market, technology, manufacturing, technology, quality, and service sectors to form R&D teams around pumping. Efficiency, structural fatigue life, boom control, overall machine stability control, and energy conservation are key technologies.

"The reliability of structural components is a key factor in determining the life of a pump truck." Wu Dezhi introduced. In the past, the development path of the pump truck was that the product was developed and manufactured, sold to the customer, and then went to the construction site; any problems had to be returned to the manufacturer after the actual operation. Now, in order to solve specific problems and extend the service life of products, Zoomlion project team proposes a virtual prototyping-based fatigue life simulation method for structural parts of pump trucks, such as booms and undercarriage legs, at the design stage. The fatigue life of the structure is predicted and the weak fatigue life of the component is determined. According to the classification and determination of each weld of the structural member, different quality levels of the weld correspond to different fatigue stress thresholds to ensure that each weld has the required fatigue life. Then, an on-site equivalent test is performed.
“Some places do not live up to the expected lifespan and start over from scratch to redesign and re-test; until they reach the goal.†Li Xiangan, the project team, revealed to the media that in the winter of 2015, the trial had entered a critical period that took more than three months. During the period of time, the workload of the pump truck was simulated for more than 10 years. Every day, the work of the pump truck was carried out without interruption. Several people in the project team took turns.
Hard work pays off. The test results of the equivalent bench test in the field show that the booms and underframe legs and other structural parts of the 56-meter boom concrete pump truck that has been fatigue-optimized have reached a lifespan of 450,000 square meters and have reached the European advanced level. .
In addition to the “fatigue life of structural componentsâ€, the pump truck also performs technical research and various breakthroughs around pumping efficiency, fatigue life of structural components, boom control, overall machine stability control, and energy conservation.

The full-case adaptive pumping control technology breaks through the difference in the pumpability of the difference material, effectively overcomes the “picky eater†problem of the pumping system, and achieves a 65% reduction in the rate of blocked pumping. At present, the company has produced altogether 62 patents, including 41 invention patents, 18 utility model patents, and 3 exterior design patents.
It is understood that in the recent Zoomlion 4.0 product tour held in the country, the pump truck also received praise again and again, many customers personally on board experience, for the appearance and configuration of the vehicle "tall" on the like. At present, the product has been sold to Anhui, Hubei, Shanghai, Guangdong, Jiangsu, and various provinces and regions in the northwest, with a total realized sales of 2.12 billion yuan. The market share ranks first in the world for similar products.
According to the relevant person in charge of the company's project, in addition to concrete pump truck products, the “Key Technology and Application of 3,200-ton Caterpillar Cranes for Nuclear Power Construction and Construction†declared by Zoomlion won the second prize of the 2016 Hunan Science and Technology Progress Award. "High-chromium cast iron, thin-walled pipe fittings made of it, and the preparation method of the thin-walled pipe fittings" won the first prize for the Hunan Province Patent Award in 2016. These three items were also honored by the provincial government. (This article comes from Zoomlion.)
