Concrete Mix Truck was used to transport construction concrete of special truck; cylindrical mixing drum to carry the concrete mixed on trucks. During transport always kept stirring drum rotation to ensure that concrete does not carry solidification. After the delivery of finished concrete, usually rinsed with water inside the mixing drum, to prevent residual concrete hardening space, so the volume of the mixing tube is less and less.
Concrete mixer truck device component by truck chassis system and the concrete mixing system . China's production of concrete mixer truck chassis to use more vehicle manufacturers to provide two types of GM chassis. Its special mechanism includes power take off, mixing drum frame, gearbox, hydraulic systems, the mixing tube, the control mechanism, cleaning system.
Working principle is that by PTO take out Truck chassis power,
and drive hydraulic system of the variable pump, the mechanical energy into
hydraulic energy to quantitative motor, motor and drive reducer, reducer drive mixing plant, for mixing concrete. Concrete Mix Truck Concrete Mix Truck,Concrete Pump Truck,Concrete Mixture Truck Suizhou lishen special vehicle co.,ltd , http://www.ls-truck.com
Huarui won the bid slightly better than the gold wind reporter learned that the Hami project Sinovel wind power and gold wind technology won the bid 800,000 kilowatts, two dominance. In the Zhangjiakou dam project, Sinovel won 550,000 kilowatts of wind power, and Goldwind won the bid of 500,000 kilowatts. The remaining 650,000 kilowatts were divided by several companies such as Yunda, Xiangdian, United Power and Mingyang.
According to statistics from the reporters, the tender price for the 1.5 MW wind turbine equipment has basically been below 4,000 yuan. Although Goldwind Technology reported the lowest price of 3850 yuan/kW, it did not make it the ultimate winner of the Zhangjiakou dam project. . The 3.0 MW wind turbine equipment won the lowest price of 4,100 yuan, and the cost per unit of kilowatts for wind turbines dropped by 1,000 yuan per year.
The two giants divided up 80% of the projects. The tender amounted to 3.3 million kilowatts, involving 23 projects. Among them, there are 14 projects in Zhangjiakou dam, totaling 1.5 million kilowatts; and 9 projects in Hami, Xinjiang, totaling 1.8 million kilowatts. Four companies, including Sinovel Wind Power, Goldwind Technologies, Guodian United Power, Dongfang Electric, Mingyang Wind Power, and Dongfang Electric New Energy Hangzhou Equipment Co., Ltd., participated in the bidding.
This reporter learned that in the bidding for the concession, Sinovel won 1.35 million kilowatts of wind power, and Goldwind won the bid of 1.3 million kilowatts. The giants of the two wind power companies divided more than 80% of the bidding projects, and Donghua No. 3 in the industry won the bid, showing that the domestic wind power equipment manufacturing industry is the only two large-scale structure.
The results of the concession bidding for the 3.3 million kilowatt wind power equipment in Zhangjiakou Dam and Xinjiang Hami one week ago were announced this week.
