According to Cai Dong, general manager of China Heavy-Duty Truck Group Co., Ltd., China National Heavy Duty Truck (000951, stock) relying on independent innovation to build a high-power heavy truck, low fuel consumption, comfortable driving and other high-end heavy truck Howo A 7, this year sales are expected To reach 10,000 vehicles will lead the new trend of high-end heavy truck development in China.
Entering May each year, the sales of domestic heavy-duty vehicles began to decrease, but sales of HOWO A 7 in China National Heavy Duty Truck continued to be hot. This year, as of mid-May, Howo A 7 sales reached more than 4,300 vehicles, more than twice the annual sales in 2009.
Wei Zhihai, Deputy Secretary of Party Committee of China National Heavy Duty Truck Group, said that the HOWO A 7 project was completed by the end of 2005 and completed at the end of 2008. It has used more than 130 new patented technologies and its driving comfort, safety, reliability and electronic level have been Up to the international advanced level.
Howo A 7 is not only favored by domestic customers, but also successfully exported abroad. Recently, the first batch of 500 Haowo A7 tractors from China National Heavy Duty Truck set out from Qingdao port and will soon arrive at the Cabello port in Venezuela. This is the first time that China has exported heavy trucks to Venezuela in large quantities.
In the first four months of this year, the sales of the HOWO A 7 market have been increasing. It is expected that the sales situation will continue to be good in May and June, and the company will quickly enter the mature period of the market. It is expected that the total sales volume in 2010 will reach 10,000 units.

There are different kinds of technology to roll the metal plate:
Four-roller machines have a top roll, the pinching roll, and two side rolls.
The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The side rolls do the work of bending. The pinching roll holds the plate.
Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls.
The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders.
For example; The side-rolls are what produce the mechanical advantage. With the side rolls all the way open, one has the maximum mechanical advantage. With the side rolls all the way in, you have the least mechanical advantage. So, a machine has the capability of rolling 2-inch-thick material with the maximum mechanical advantage, but a job is only 1/2 inch thick. Reduce the mechanical advantage and one has a machine that can roll from 1/2 to 2 inches thick.A plate rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape.
