Product Description:

QAY800 adopts 7-segment oval boom, the length is 84m. The boom can be separated into two parts. After dismantling the 5th-7th segments and installing a 2.5m independent boom head, the length of the boom is 52m, forming a 4-segment short-boom product; on that basis, installing the tower boom will improve the performance of the super-lift, which is specially designed for lifting the 2MW wind power.
QAY800 adopts 8-axle chassis, full-wheel steering, and X outrigger structure. The front and back swing can be realized by the cylinder. The lateral outrigger span is 13m.
To transfer the machine flexibly and facilitate the assembling and disassembling of the boom, the boom is added a self-assembling and self-disassembling device which is controlled by the independent power producer. The weight of QAY800 in travel is 96t, carrying all the outriggers and the whole turntable. The boom is transported independently.

Q:What are the major of construction machinery application and maintenance?
Like, the construction unit, construction of highway, railway and metro will be used in some machinery, is the mechanical construction, this job is hard, but the salary is very high, if they will repair the machine will boot, graduate students in higher vocational colleges generally work for 3 years, wages to less than eight thousand.
Q:What subjects are specialized in mechanical manufacturing in secondary schools?
We already have: Metalworking Training, mechanical design, basic curriculum design, training, fitter training, CNC machining training, "machinery manufacturing foundation", "now control technology"
Q:Can mechanical design be published in nature?
Naturally, this magazine does not have any columns related to mechanical design, so it is unlikely to pass if it is submitted
Q:Excuse me, what is the meaning of the construction team Jixietaiban? What is the meaning?
Mechanical engineering work eight hours a day. Known as a machine called a team working a shift, two machines working a shift or a machine work in two shifts of two classes called down and so on!
Q:What is the rental tax rate for machinery and equipment in construction?
Construction machinery rental belongs to the scope of business tax collection, applicable to the "business tax - leasing industry" tax items, service invoices, business tax rate of 5%, generally issued at the local tax.
Q:What kinds of construction machinery are used in the Three Gorges Project?
Hydraulic excavators and wheel loaders, bulldozers, graders, hydraulic drilling machine, truss boom crawler crane, truck crane, gantry crane, luffing cable cranes
Q:What is the difference between the application and maintenance of construction machinery and the operation and maintenance of automobiles? What a promising future!
As far as maintenance is concerned, the maintenance of construction machinery is mostly in the field or on the construction site. It needs to withstand the scorching sun or the ice and snow (and partly in the factory) as well as the bumpy journey back and forth. The car is generally in the factory building, and some have air-conditioning, better conditions.
Q:Construction machinery if the use of diesel engines, the use of motors, the general choice of DC motor or AC motor?.
The AC power is large, the DC power is small, and as for synchronous asynchronous, it is not very important considerations, depending on the drive you select, and you need the specific speed, load capacity
Q:What are the differences between diesel engines used in construction machinery and diesel engines for automobiles?
3, the difference between the structure and the use of gasoline is also large, such as: big fan, exhaust pipe into the flywheel and connecting device. The big water tank. The car engine running in high speed multi zone, and engineering machinery often running in the maximum torque speed. So feel engineering machinery engine strong. Oil requirements than the car.
Q:What are the concrete construction machinery?
Mixing truck (247) pump (162) side dump concrete truck (32) rail type mixer (9) semi trailer (11) bulk cement truck (17) dry mortar transport equipment (20) mounted concrete pump (53) cloth rod (19) other pumping machinery (63) the spray machine (10) pouring equipment (4) air chute delivery system (8) pneumatic lift system (3) bin pump system (7) chain conveyor (5) screw conveyor (11) high speed elevator (16) high bucket chain hoist building (20) (37) the belt conveyor (15) powder conveyor (7) crane (38) concrete feeding equipment (72) loader (31) cloth car (3)
