Truck-mounted Concrete Pump with the World Longest Boom Makes Its Debut

In September 2012, Zoomlion 101m truck-mounted concrete pump rolled off the line. After carrying out the strict measurement, the UK Guinness World Records recognition officer announced that the 101mtruck-mounted concrete pump with 7 axles and 7 sections has a total length of 101.18m, and belongs to the truck-mounted concrete pump with the world longest boom. It is noteworthy that the 101mtruck-mounted concrete pump is a new-generation composite technology product that was meticulously development by Zoomlion in the wake of its six-axle 80mcarbon-fiber placing boom pumper that was launched into the market on September 28. It integrates 120 proprietary technologies and belongs to the truck-mounted concrete pump with the world longest boom and the highest pumping speed.

On July 28, 2013, Zoomlion 101m carbon-fiber placing boom pumper with the world longest boom, which just registered a new "Guinness World Record", made its debut at the "Central China No. 1 Towering Building" Wuhan Center, and thetruck-mounted concrete pump integrated a series of cutting-edge technologies in the truck-mounted concrete pump R & D sector, such as carbon-fiber placing boom structure 7-sectiontechnology, boom damping and coordinated motion control technology, all-condition load simulative design analysis technology, and high-efficiency large-displacement technology etc. Reputed as the most luxurious debut in the construction machinery sector, itbrought together several industry experts, construction machinery industry association leaders, and 100-odd construction machinery product users.

Enormous Steel Boom Pumps Concrete in the Sky and Brings Astonishing Scenes

At 16:00 on that afternoon, the 101mtruck-mounted concrete pump's debut kicked off at the Wuhan Center Construction Site. Standing in the podium building of Wuhan Center, you will get a view of an enormous steel boom that is uninterruptedly pumping concrete to the top of the fourth floor of the Wuhan Center's Main Building. How magnificent it is!

Deng Weihua, a project manager in charge of construction from China Construction Third Engineering Bureau, voiced his opinions on the 101mtruck-mounted concrete pump's construction work on site, and he said: "I sum up this amazing construction with three words, namely, long, stable, and fast. Herein, ‘long' refers to fact that the 101mtruck-mounted concrete pump realizes the matchless pumping transport with super-long spanning distance in the extreme working condition. ‘Stable' refers to the fact that the 101mtruck-mounted concrete pump with the world longest boom completes steady construction, and it even outshines the short-boom truck-mounted concrete pump in working stability. ‘Fast' refers to the fact that 101mtruck-mounted concrete pump's concrete pumping efficiency is 1.36 times that of the 60mtruck-mounted concrete pump."

 It is learned that an underground parking lot was planned around the Wuhan Center's main building, and so the ground surface is hollow. Due to this, it is impossible for construction workers to erect heavy-duty construction machinery near the Wuhan Center, and the truck-mounted concrete pump must be parked 50-60m away from the Wuhan Centerfor long-distance pumping transport. Such a special ‘arena' is a perfect site for the 101mtruck-mounted concrete pump to exert its super-long boom. However, during the working and turning process, a minorvibration on the pumping mechanism may be amplified by the boom, and evident shaking cantake place at the boom end, leading to pouring error, which is a technical bottleneck for R & D of long-boom truck-mounted concrete pump. According to Deng Weihua, 60m long-boom truck-mounted concrete pump's 180m3/h pumping delivery can be called large delivery, and 101mtruck-mounted concrete pump's pumping delivery even hits 245m3/h. Based on this working efficiency, pouring work of Wuhan Center's Main Building at current phase can be completed within 10 hrs.

Frontier Technology Drives Industrial Upgrade

 Speaking of "101m", Chen Xiaofei, Vice President of Zoomlion and General Manager of Concrete Machinery Branch Company, said with a deep feeling:"the 101mtruck-mounted concrete pump resembles my own child, and it not only condenses Zoomlion Truck-mounted Concrete Pump International R & D Team's unremitting efforts in technological innovation, but also represents the world most advanced truck-mounted concrete pump technology achievements." While being interviewed about the 101mtruck-mounted concrete pump's significance, Chen said: "So to speak, our 101mtruck-mounted concrete pump can be likened to a sophisticated military product. While military technologies are being applied in the civil sector, we will find civil products a revolutionary upgrade. Likewise, if we apply the 101mtruck-mounted concrete pump's innovative technologies (like carbon fiber material technology, damping technology, and load simulation analysis technology) into other truck-mounted concrete pumps, we can feel more at ease in application. All long, Zoomlion long-boom truck-mounted concrete pump grabs the lion's share in the market, exemplifying that Zoomlion technological R & D achievements receive high recognition from the market. Also, successful R & D and application of the 101mtruck-mounted concrete pump further shows that Zoomlion truck-mounted concrete pump has become the deserved premium brand in the truck-mounted concrete pump sector."

Su Zimeng, Secretary-general of China Construction Machinery Association, said: "Zoomlion long-boom truck-mounted concrete pump now is world advanced, and its technological innovation not just drives development and progress of products of its kind, but also mirrors China manufacturing industry's leap-forward development."
