Product Description:

 QAY220 all terrain crane inherits the 222 patent techniques and 38 new patents techniques.
• The product adopts 6-axle chassis, 12x12 full-axle steering, 6-segment retractable boom, and oval section. The variable section technique make the machine has big antitorque and high stability. The optimized various retractable boom combination play the performance to the most.
• The self-combination counterweight technique developed by ourselves can effectively improve the lifting performance by 30%. The electrohydraulic proportion control multi-axle steering mode can realize many kinds of steering modes. The new brake technique can reduce 2/3 maintenance cost, and improve the travel safety. The comfortable cabs and outrigger operation completely show the humanity design concept. Equip with the XCMG unique control system, auxiliary retractable boom system, virtual wall system, perfect failure diagnosis, real-time detection, CAN technique, etc.

Q:What are the employment trends of mechanical majors?
To see how the capacity and diploma, the operation is the most low-end equipment, engage in the end of the design, high-end R & D. But for many years working experience: 1 draw two school stuff, can come in handy in the minority, 2 work is difficult. So. The best situation is school you can stuff later undertaking to lay the foundation.
Q:What are the common mechanical processing methods?
Common mechanical processing methods are turning, milling, grinding, boring, drilling, wire cutting, EDM, etc..
Q:If I use Mobil Steyr engineering machinery oil, the most suitable collocation way??
Engineering machinery with black Mobil Steyr 15W40 fighter CG-4 OK
Q:What are the core technologies involved in the core components of construction machinery?
1, the core components of construction machinery core technology in which areas are possible, as long as we do not know the technology, only a few people know, and this technology is also a lot of applications, this is called the core technology.
Q:How to improve mechanical design ability!
1., we must first understand what the output is: rotation? Move? Constant velocity? Gearshift? Magnitude and direction of force? To specific numerical value 2., to meet the output, which structural modules are used to realize the coordination and cooperation between the 3. modules: what is the mode of control, what is the input signal?
Q:What is a mechanical mouse?
IAS acquires images by lenses, which are further processed by the DSP to determine the direction and distance of the movement, and DSP generates a set of relative displacements in vertical and horizontal directions. SPI allows two-way communication between the mouse processor and the optical sensor. Resolution and refresh rate are two key indexes to measure the performance of optical mouse. They reflect the capture ability of photoelectric mouse at the time and space level respectively. The interaction of these two capabilities, combined with the contribution of the optical system, determines the actual performance of the photoelectric mouse.
Q:The state stipulates that the machinery processing industry accident how to compensate?
The basic requirements of mechanical equipment in the whole period of machinery safety regulations, may be due to mechanical failure of the equipment itself, jeopardize the security of all types of accidents have been understood and occupation health caused by injury and avoid unnecessary physical consumption, with operators, mental tension and fatigue. Whether it is design or machine safety predetermined function, should follow two basic methods: proper structure design choice, as far as possible to avoid or reduce the risk; by reducing the operator's involvement in dangerous areas, in low risk people
Q:How do the fixed assets in accounting distinguish between (machinery and other production equipment) and equipment (tools and tools) related to production and operation activities?
Whether it belongs to the production and operation of the equipment, mainly to see whether the equipment is for production and operation services, or not, it does not belong. The sewage pipe pump does not belong
Q:What is the management of construction machinery?
This should be the member of the eight members of the inside of the construction machinery to do, (1) seriously implement the guidelines, policies and regulations concerning the management of state and construction machinery construction enterprises;
Q:How much money do you need to invest in construction machinery parts?
Graphic design can not use such a high configuration, dual core heat dissipation is not suitable for long time design requirements, and this is not necessary. Single core P43. 06, of course, 775 stitches. Memory with 1G 533 is ok. Seven rainbow X1300 discontinued, you can use 7300GT 256M flames ares version.
