The innovation of the "-3" series paver: two super 1880-3 L pavers are spreading a modern, long distance, high quality highway section near the Shang Yong border.
Project background
A 50 km long, 24.5 m wide construction section on the Kunman Expressway connects Kunming with the capital of Thailand, the capital of the south of China and Bangkok, and it is very important to improve the border traffic of the three countries and promote the three party logistics.
Accelerate the foreign trade process between Laos and Thailand
With a population of 6.8 million, Kunming is not only an economic and Technological Development zone, but also the seat of many booming and export-oriented companies. As the capital of Yunnan, Kunming played a key role in the trade between China and Laos and Thailand. This brand-new Kunman Expressway will serve as a link between South China and Southeast Asian countries, and it is planned to be fully opened by 2020. The Yunnan referendum construction group is responsible for the construction of the 50 km section along the Chinese border to Laos.
Daily spread of 1.1 km
The logistics of the project requires precise planning. Because the asphalt mixing plant is located 40 km away from the construction site. Nine skip trucks and three cars per class provide fresh mix for 2 Fu Le paver. "Under this condition, we can build an average speed of 4 meters per minute and complete 1.1 km per day. This has greatly ensured our construction process. " The project manager of the Yunnan referendum construction group said.
L paver with long hopper
To ensure that the material is not stuck, the company has designed a large 242 cm long hopper for the super 1880-3 L paver, which is specially adapted to the various materials in the Chinese market. Because the hopper is low, the sidewall is wider, and the front is equipped with strong rubber plates, unloading becomes easier. In addition, super 1880-3 L can save 15t, which makes the paving team have enough reserves to deal with all possible situations, such as paving under the deck or spreading the material that can not be easily dump into the hopper.
The transportation system makes the construction of the expressway easier.
Construction equipment for large projects (such as Kunming high speed) usually requires design that ensures high performance construction. Super 1880-3 L meets all requirements, especially its delivery system. Both sides scraper feeder and stirred dragon are strong hydraulic independent drive, ensuring a yield of up to 1000 t/h. The proportional controlled, continuously monitored scraper and agitators, together with the highly adjustable agitators, ensure that the iron plate has an ideal cloth effect in front of the ironing - the same as the straight and the bend. The material head is monitored by the sensor in real time and adjusted accordingly, and the manipulator can also see the material level clearly.
Construction and construction under ECO model
In this construction project in Yunnan, the super 1880-3 L paver has enough power reserves. This paver is equipped with AB 600 TV hydraulic telescopic ironing plate for each hot paving shop with a width of 4.1 m. The stepless widening range of the Fogler hydraulic telescopic iron plate is from 3 m to 6 m. The maximum spreading width can be up to 10 m by equipping the mechanical extension block. If the paving width is small, just like the construction site in Yunnan, then the ECO economic mode is more efficient. Dongfeng Cummins six cylinder diesel engine, rated power 158 kW, press button (ECO economic mode), its speed from 2000 to 1700 rotating per minute, enough to meet the needs of most working conditions. Even in normal operation, the engine is very fuel efficient. This is achieved through the innovation of the "-3" series paver -- the EcoPlus energy saving and emission reduction package. The package contains a range of measures that can significantly reduce fuel consumption (24%*) and noise levels, such as: hydraulic pumps work as required.
Many highlights of the 1880-3 L general paver.
Maximum paver width of 10 m
Maximum paver capacity 1000 t/h
The maximum paving thickness of 50 cm is strong and high quality, which ensures a longer service life of the machine and reduces the cost of vulnerable parts.
A powerful diesel engine with a rated power of 158 kW.
V GELE EcoPlus energy saving and emission reduction packages, low carbon and environmental protection, greatly reduce fuel consumption and noise levels.
ErgoPlus 3 human-computer interaction intelligent enhanced control system, increased more in line with ergonomics design features, easy to operate safely and efficiently.
Iron plate selection for various applications:
AB600 hydraulic telescopic iron plate and SB300 TV / TP1 mechanical extension iron plate are suitable for asphalt construction to ensure high quality and flatness.
SB 300 HDT mechanically lengthened ironing plate for base construction.
A successful partnership with the group
The super 1880-3 L paver was chosen in the construction project, not only because of its excellent performance, but also a vital role for the pleasant cooperation between the Yunnan referendum construction group and the stonen group. "For four years, we've been using Fogler pavers, Hummer rollers and Wittgens cold milling machines, which are simple, efficient, and very trustworthy." The project manager said. "These machines are absolutely first-class. We use the flawer paver to get the perfect paving effect. At the same time, thanks to the easy to understand ErgoPlus3 operating system, even the new machine can quickly master and operate skillfully. It is also important that at any time, as long as we need it, the service team of the TDG group will provide us with support and help in time.
