K to King 20 years, this is an experience, but also a spirit

In 2000, four cranes, including QY16K, QY25K, QY35K and QY50K, were rolled out in batches, which caused a sensation in the industry. In the past 20 years, nearly 120,000 Xugong K-series cranes have been put into the market, which broke out at the beginning of the century. In the past ten years, the sales volume of nearly 40,000 units of QY25K5-I has been regarded as the classic of Xugong cranes by many people. Work.

Compared with the highlights brought by the K series to Xugong and even the Chinese construction machinery industry, few people know that the growth process of the K series is a testimony to the history of XCMG. Today's "K Series 20 Years" topic, we invited two technical experts who focus on the research and development of small tonnage cranes, and asked them to talk about this experience of adversity.

In 1999, it was the most difficult period for Xugong. The debt exceeded 100 million yuan. If it is not reformed, it may face bankruptcy crisis at any time. Therefore, after the establishment of the new leadership team, we began to promote the development of new products. We were very excited at that time. Everyone wanted to let go and let the company revitalize.

However, when Xugong cranes and all of them joined the battle to develop K-series products, they realized that reality is far more cruel than imagination. In order to determine the product type spectrum, Xugong set up a 15-person research team at that time, and launched the first in-depth and most systematic “user demand survey” in the history of Chinese cranes and even China's construction machinery industry. When visiting across the country, what we think about every day in our minds is what products users like, and how many tons of equipment have the most market.

After several months of non-stop, the K series finally established the original basic tonnage models – 16 tons, 20 tons, 25 tons, 50 tons. At this time, XCMG cranes also opened the first product design and series design in China. "The first river."

After the official entry into the design phase, the new "roadblocker" is placed in front of us - how to coordinate the height of the cab and the boom, whether the transmission system is set to a single or multiple configurations, how to determine the engine selection and front and rear position The controversy in the conference room continued from the early morning to the dark, and the overall designer Zhao Bin and his colleagues racked their brains to break through the puzzles.

Many people are thin, have no time, no heart to eat, the problem is in front of us, time is not waiting for people, we must develop the K series as soon as possible, in order to let XCMG get a new life. Walking through this road, I firmly believe that in the future, no matter how the K series upgrades, how to change; the cohesiveness and spirit formed in the development of this product will be passed down from generation to generation.

Narrator status: technical experts involved in several "customized" designs of the K series

When Xugong introduced the K-series cranes in 2000, the pilot control, high-lift counterweight, full-head cab appearance, and full coverage of the decks shocked the world. No one thinks that China's local crane manufacturing brand can develop such advanced crane products, and no one thinks that Xugong, who is in the critical period of transformation, can overcome the technical problems of design and manufacturing in a short time, and launch the first domestic one. A series of cranes with a "customized" connotation. All of this was inseparable from the "forgetting me" of the Xugong crane developers at the time.

As a transformation of Xugong cranes at that time, the K series was highly anticipated during the development phase. It not only inherits the practical advantages of XCMG's traditional crane products, but also combines the needs of the first line of the market, with innovative requirements that are easy to control, stable and environmentally friendly.

In order to win the launch of the K series, I and my colleagues worked on the drawings and discussions around the clock. Regarding whether the cab is half-headed or full-headed, we discussed it for several months, and then went into the gearbox and whether the engine should be discussed in a modular design. During that time, I took a book at home every day. The combination changes, and the meal is reluctant to throw the book down. If the painting is not good, the tea is not good. Everyone is forgotten to work, otherwise it is impossible to have the success of the K series.

Including me, at the time, the technical team involved in the K-series R&D had a large number of employees in their youth. Their active thinking and exuberant energy complement each other with the actual experience and steady style of the old staff. While giving the K series innovative design, it also guarantees the quality of the equipment as always.

The emergence of the K series, in my opinion, is the first manifestation of China's crane technology innovation, breaking the market's understanding of truck cranes, adopting new system design and industrial modeling, using modular design ideas, from imitation innovation to independent innovation. Try it boldly. Since then, really, the Chinese crane industry has opened a new page because of the K series.

"Study in the middle of the job, the window of the window," is the most authentic portrayal of the XCMG crane technology research and development personnel. In the past 20 years, they have become the backbone of the team, and they have cultivated a number of new forces. In the relay run of generation after generation, XCMG cranes have not only renewed their upgrades, but the K series has also become the "Rise of Chinese Brands" in the global crane era. Important bearer. (This article is from Xugong)
