More excellent performance
• The optimizing layout of the machine makes the stress of the main bearing carriers more reasonable, and the lifting performance is higher than the products with the same tonnage.
• Apply the mature jib technique which integrates plug-in boom head, embedded boom block, and special telescoping mechanism, which makes the jib more stable and reliable.
• Optimize the stress design. Adopt the box-type outriggers which have larger span, stronger rigidity, and better stability.
More reliable quality
• Adopt the classic K series jib telescoping technique, working safer and more reliable.
• Make the most complete safety device system in the industry, ensuring the lifting safer and more reliable.
• The comprehensively upgraded brake system adopts double circuit air pressure design. Multiple systems ensure the brake safety of the truck during travel.
• The new power steering mechanism adopts hydraulic power design, which makes the steering light, flexible, and precise, and ensures the safety of the truck.
• The intensity and rigidity of the rotary table and frame structure with high rigidity are completely coordinated.
• The perfect integration of the design and structure realizes the automation of welding, which is more reliable.
Easier to operate
• The high efficient and energy efficient load sensing hydraulic system is sensitive to operate and precise to control, having good slight mobility.
• Optimize the control levers, which is easier to operate.
• The cab adopts orthodrome front windscreen, having wider operating views.
Easier to maintain
• The optimizing design of the pipeline traces makes the layout more scientific and reasonable, greatly reducing the dismantling and installing time of the pipelines and the maintenance expense.
• Completely upgrade the electrical system. Adopt anti-creep connector clips, greatly prolonging the service life of the parts.
• Adopt K series rope anti-disorder technique, improving the lifting efficiency, reducing the labor intensity, and prolonging the service life of the steel rope.
• The telescoping steel wire rope oriented and protective device avoids the steel wire rope out of the track and broken.
• Fully covered walking plate supplies a platform for the maintenance, and effectively protects the parts of the machine.
More energy-efficient and environmental friendly
• Adopt double industrial automation control engine, featuring strong power and energy efficiency.
• Under the economical mode, it can meet the engine power requirement of the normal lifting work. Under the high power mode, it can meet the requirement of the high challenge and high efficient lifting work.
• Adopt the high power radiator, avoiding the system from bad cooling, solving the problem of oil overheating, and prolonging the service life of the hydraulic oil.
• Adopt the advanced matching technique, which makes the design more scientific. It can reduce the consumption of the mechanism, prolong the service life of the machine, and has high residual value.

Q:Application of lean production in construction machinery
With the increasing complexity of construction machinery, its maintenance costs are increasing, the dependence on maintenance is increasing day by day, and higher requirements for its reliability are also put forward. The current construction machinery maintenance exists in the maintenance range is too large, maintenance frequency is too high, too much inventory of spare parts and maintenance process optimization not "waste" phenomenon, in view of these phenomena, the lean thinking proposed a good solution.
Q:What are the future prospects of mechanical design, manufacturing and automation? How about salary after employment?
The employment outlook is still very good, at least now the employment rate of engineering or mechanical electrical and mechanical high, because graduates can do too much, it is the automotive industry, there is a car factory, auto parts factory,
Q:Cost of construction machinery use fee
Because labor costs, material costs, construction machinery use fee called "basic direct fee", plus "other direct costs" is the direct costs of the project, for example: "the basic direct fee is 1 million yuan, other direct costs" rate of 6%, then the "other direct costs" amount is 60 thousand yuan, direct project fee is equal to 1 million 60 thousand yuan. (similar to this name is in the professional quota appears, water conservancy quota, highway quota is so called name; general construction, especially civil engineering are in accordance with your statement)
Q:What are the listed companies of construction machinery in China? What are the shares of A?
You do not know what kind of system software, but generally have plate classification, selection of machinery manufacturing industry classification inside there is a plate. It's full of stock in the industry. The typical representatives are Sany, ZOOMLION and so on.
Q:What about the title of Mechanical Engineer?
(a) the professional (refers to the design and manufacture of machinery and automation, material forming and control engineering, process equipment and control engineering, see Table 1 below) or similar professional (refers to the metal material engineering, packaging engineering, printing engineering, textile engineering, food science and engineering specialty, see Table 1 below.) Bachelor degree or degree.
Q:What is mechanical engineering?
Introduction to mechanical engineering related science and technology as the theoretical basis, combining the technical experience in the production practice, study and solve in the application of discipline development, design, manufacture, installation, use and repair all kinds of machinery in all theoretical and practical problems. Machinery is one of the five essential elements of production and service in modern society (human, capital, energy, material and machinery), and is involved in the production of energy and materials.
Q:Labor costs, materials costs, machinery costs accounted for the total cost of the project
General civil construction: labor costs 18-21%, material costs 50-55%, machinery costs 8-11%, the rest is safety, civilization, management fees, profits, fees, taxes
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?
Machinery and other production equipment, the lowest fixed assets depreciation period of 10 years machinery, machinery and other production equipment, including various types of machinery, machinery, machine production line and auxiliary equipment, various types of power, transport and conduction equipment etc..
Q:How much money do you need to invest in construction machinery parts?
CD-ROM is best to use Samsung's DVD engraved, ASUS's noise is quite large oh. With the background of case 8185B, a power supply for the mute. Display is best to use NESO's Dragon tube, do map, that is, to an effect.
Q:What are the concrete construction machinery?
The steel bar bears the tension and the concrete bears the pressure. The utility model has the advantages of firmness, durability, good fire resistance, steel structure, steel saving, low cost, etc..
