The first half of 2013, small engineering machinery product sales of the engineering machinery industry has become the focus of attention. Intelligent, miniaturized seems to have become the future development of the industry trend. However, small make up remind immersed in the joy of the enterprise, intelligent is the direction of future development of engineering machinery industry, but small is definitely not the only direction for the future development of construction machinery enterprises.

Perhaps, this is now the specific period of the specific hot products. At present, with the increasing urbanization and accelerate the pace of labor costs, machinery instead of manual labor has become a major trend, the promotion of small engineering machinery products of the popular to a certain extent, but only by a small engineering machinery product sales for the entire industry to bring a big recovery is clearly not realistic. "Yanan city" is very powerful, small and large mechanical who is stronger, control of construction market. "Both fine blossoms in their season, and each has its Fang", cannot slant on small machinery, large excavators also has its necessary.

Defects of small excavators born ""

Influenced by the new urbanization advancement, the domestic each big host manufacturers, invariably focus on the promotion of small excavator and Datong terminal clients, especially some foreign brand manufacturers. Recently, the small excavator sales has become the focus of attention of the engineering machinery industry. In fact, since the end of 2012, with the Ministry of water resources to the layout of a new round of spring and winter irrigation and water conservancy infrastructure construction "battle", over 300000000000 yuan pull function of farmland water conservancy construction investment of small excavator sales obvious. At the same time, as China's urbanization and labor costs to upgrade, more and more enterprises tend to use mechanical equipment instead of labor, to some extent also to promote small dig demand. However, large and medium-sized excavators, lucrative but sells suffocate suffocate, small excavators although marketable, but must face to sell more to compensate more dilemma, also should continue to develop the small excavator?

Foreign large hydraulic excavator

With the rapid development of hydraulic excavator into large market, large hydraulic excavator is receiving more and more attention. So the development of large hydraulic excavator abroad is how? The development of foreign large hydraulic excavator about 70 years from the last century. In 1979, Hitachi has successfully developed UH50 type shovel superlarge hydraulic excavator, bucket capacity is 8.2m3, the weight of 175t.

In 1987, when the shovel Hitachi EX3500 the world's largest super large excavators (bucket capacity 18.8m3, the weight of 330t) developed in Japan, and in that year and the development of bucket capacity of 22m?, shovel type EX4200 weight of 420t super large excavator. At this point the other companies in the world have developed super large hydraulic excavator, such as Komatsu, caterpillar type 5130 PC1600 type, R992 type, R994 type, Liebherr, Terex (acquired by O&K) RH20C type, RH90C type. After 1990, super large hydraulic excavator bucket capacity increasing, reached above 50m3; machine weight increasing, more than 800t, at present already formed very large mines and earthwork type hydraulic excavator series.

After 30 years of development, the largest of the weight of large hydraulic excavator has exceeded 900t, close to 1000 tons, bucket volume is up to 50m3. Super large excavator manufacturers mainly manufacturing power in Germany, Japan, the United States and other engineering machinery, the famous manufacturer caterpillar, Komatsu, Hitachi, Liebherr company, "quadrupedal" situation. In 2012, modern in France exhibition launched the first of more than 100 tons of excavator R1200-9. The world's largest tonnage of excavator Terex RH400 (now the caterpillar 6090) hydraulic excavators, heavy 980 tons. (editor's note: caterpillar type 6120BHFS hydraulic excavator large hybrid has been on display to the public, will be officially put into operation in 2014. Its weight is 1270t, the output power of the engine 3360kW, bucket capacity according to the material's density is up to 46~65m3. )

Large hydraulic excavator market to be developed

In recent years, some people say that because of the small dig unpopular sales, the big dig was "relegate to limbo", in fact, domestic and foreign large-scale mining and construction of water conservancy project for off-road dumper continuously in the direction of the large-scale development, in order to adapt from large truck trend, which matched with the truck in joint operations, super large excavator is bound to raise the bucket capacity, the unit time increased workload, which has high production efficiency. Therefore, a growing demand for super large excavator. Just because of the huge monster do not often appear in our line of sight, so it's easy to this part of the market ignored.

At present, super large excavator in order to obtain the maximum loading capacity, mostly is the large capacity is bucket. With the development of technology of hydraulic excavator, large hydraulic backhoe excavator development and market demand increases, cause the attention of the industry. In June 3rd, Liuzhou to Zijin Mining delivered a large excavator first custom-built, which makes the current size of digging "uneven" to ease the situation.

It is understood, according to the special needs of lonking Zijin mining operation, careful development of large engineering machinery and equipment for mine operation, and Zijin Mining also has been deployed, all future mine new equipment all use of lonking brand. So to say, "uneven" just lies in whether the enterprise real intentions. Mining Group is the main buyers of large engineering machinery products, how to move
