Product Description:

Based on the success of QAY130, QAY160, and QAY200 all terrain truck cranes, QAY 240 is another new all terrain product developed by our company through extensive market research and technical demonstration. It inherits the successful experience, and adopts new materials, new technologies, and the most advanced steed structure design and computer control technique. The main hydraulic parts and load bearing materials adopts international parts and components, effectively improving the product’s performance and reliability. The application of hydropneumatic suspension all terrain chassis, electronic proportional control system, limit load control variable hydraulic system, U jib technique greatly improving the performance and grade of the machine. The machine has modern design, compact and reasonable layout, and excellent travel and lifting performance. QAY240 which represented the highest design level at that time attended the 2007 Munich Bauma Exhibition. It is the first time for the Chinese high-level crane shown on the international stage, extending the domestic crane’s influence in the world.

Q:What are the listed companies of construction machinery in China? What are the shares of A?
Listed companies report you can log on the Shanghai stock exchange and Shenzhen stock exchange website, in the information disclosure of periodic reports below can be found in the name and code, the construction machinery companies in the picture below.
Q:Which is better, motor or diesel, on construction machinery?
To see the condition of the site, usually using a motor on the scene of the air environment is good, and the use of construction machinery motor will require electrical lines and other equipment, equipment cycle longer, but a long time will benefit. Diesel driven construction machinery is more flexible, for a number of short-term changes in the operation of great benefits.
Q:What are the differences between loaders, gearboxes and other brands of loaders manufactured by Shandong construction machinery?
As more and more China manufacturers to produce fully meet the market demand of the most wheeled loader products, and the price is at least half of international competitors, and the failure rate is very low, so the domestic wheel loader between enterprises has formed a relatively strong "protective film", not only can resist the impact of foreign manufacturers, and can form healthy competition in the domestic market.
Q:What are the companies in the chain of construction machinery in China?
Domestic construction machinery manufacturers, each province has a level agent, and then in each region and then set up two agents (or branch), so the domestic construction machinery does not exist in the country chain.
Q:Where are the second-hand machinery and equipment acquisition?
And the general petrochemical machinery: petroleum drilling machines, oil machinery, chemical machinery, pump, blower, valve, gas compressor, refrigeration and air conditioning machinery, paper machinery, printing machinery, plastic processing machinery, pharmaceutical machinery etc..
Q:Mechanical keyboard?. How much is good?
Razer's widow only green axis, and the key conflict is relatively weak, then the characteristics of Razer products are relatively easy to bad advice; in addition, Razer is also the widow cherry (Ying Tao) MX shaft, and other mechanical and not much different, except for the spring reduces the effective pressure. ~ ~ ~ and than the original quality to the problem of the poor, is the same as the original picture of the man ~ ~ ~ ~ so it is not easy, but no brain SS powder
Q:Urgent! Is mechanical engineering major or special?
As for the difference between the special shuoxue Shuo, to see whether the school has a mechanical engineering master degree, if any, is possible according to the mechanical engineering (Academic) disciplines enrollment, may also be in accordance with the mechanical design, mechanical and electronic (Academic) (Academic), machinery manufacturing (Academic), Mechanical Engineering (Professional) to recruit students.
Q:What is the relationship between XCMG, construction machinery, Limited by Share Ltd and Xuzhou Construction Machellonery Group Inc?
The name of XCMG construction machinery Limited by Share Ltd, you can see the front of the two words is a stake in Xugong Group and the middle, the company is a listed company under the Xugong Group, referred to as Xugong Xugong Group, because not all listed, so the company is a company which XCMG group as a whole.
Q:Steel for construction machinery, including those concrete materials?
Construction machinery steel include: welding parts with Q235A, Q345 (A, D), Q690 and so on. More than 45, 35 or more alloy steel. Sheet material: Q235A; 65Mn; 16Mn; 304 sheet (less used); cast iron class: HT150; HT100; a small amount of non-ferrous metal: 6-6-3; H62; copper tube and so on.
Q:Construction machinery if the use of diesel engines, the use of motors, the general choice of DC motor or AC motor?.
The most economical way is to use a three-phase induction motor, not a particular case, without considering other motors.
