Special Crane

Special cranes are needed to perform the process steps, such as container handling, placement of goods in the warehouse of the cell, to transport the molten metal, explosives, etc. The special bridge-type cranes include bridge cranes, gantry cranes, polukozlovye, with supporting cables, cable cranes, stacker cranes, bridge cranes. The special type of boom cranes include jib, tower, portal, semi, mast, cable-stayed, cantilever and floating cranes. By construction, the lifting device and the appointment of distinguished hook, grab, pin, Hoisting, hardening, casting, landing, for undressing ingots, forging, and container cranes. The special features of special cranes, differentiating them from general-purpose cranes are allowed to include the following: a greater number of mechanisms, the likelihood of significant numbers of workers' movements, which is mainly from four to seven; limited use depending on the type of transported goods and the manufacturing process, equipped with special lifting devices winches and other machinery.

Overhead cranes (grab, grab magnetically with special lifting devices chord, ring, radial, rotating carriage, or traverse, manual hoist, single-beam suspension, etc.) are used in various industries. Cranes with special means of handling use, for example, to transport the slabs. They have better performance compared to performance overhead crane hook. Gantry cranes are used for bulk cargo warehouse at hydroelectric power plants, in shipbuilding docks. Gantry crane bridge is different from the fact that it is based on the bridge Crane by way of supports and the bridge overhead cranes is based directly on the overhead crane to crane, or road way, fixed on the beams, mounted on the pillars of the shop or on the viaduct. Design of gantry cranes terribly different. If possible, they are moving from stationary and mobile. Stacker cranes are used mainly for general cargo warehouses.

Distinguish overhead rack and stacker cranes. Crane-conveyors, bridge cranes for construction of nearly similar to gantry cranes. They are mainly used in warehouses piece and bulk goods. Bridge cranes are relying on two pillars, moving crane on tracks. In difference from the gantry cranes overhead cranes have zdorovuschy span, 100 m and more. These are often done on the console. Due to the large thermal strains bridge cranes one of the pillars typically perform "Flexible", ie, this support is connected to the bridge with a cylindrical or ball joint. When the spans of 150 m and more weight overhead bridge crane creates tensions that are close to the yield of the material. For large spans using mostokabelnye cranes, which passes under the bridge carrying the rope, whose ends are attached to the supporting pillars. Trolley moves along the supporting rope. Such a construction crane helps significant reduction in weight of the bridge. Consider the scope of the special crane boom type. Largest group of these cranes are cranes that are used mainly in sea and river ports to overload piece and bulk cargo vessel, warehouse, ship, and also in warehouses, ship building and construction. Gantry cranes are a full-circle jib cranes, revolving set to share portal crane moving on rails. In the gantry cranes when the flight trajectory of the load close to the horizontal.

Overall Product Quality Analysis

General analysis of product quality Nowadays, people often say that the quality will deteriorate as a whole. They can not be compared with previous products because of its short lifetime. However, in my opinion, the decline quality of products these days to some extent stimulated by our customers. This means that in the process of changing the quality of products, customers play the role as promouter.Imenno so products are not as good as previous ones. It is clear that businesses need to survive in this competitive world that relied on income. But where profits come from price reductions? If the price is high, customers will not pokupat.Vse they want Buy quality products at lower cost or even no cost.

In this trend, there are two ways for enterprises to go ahead and reduce the management fee and reduce production costs. Robert Iger : the source for more info. Of course, and there are other ways, for example, to increase the technical content and development, and so on. However, production costs sokraschenine is more practical. Based on this situation, Zhengzhou Kefid Machinery Co., Ltd. still insists on its principle to guarantee the highest quality. Thus, they can only reduce production costs through improved technology. And that's exactly what happened.

Zhengzhou Kefid Machinery Co., Ltd. introduces advanced international technologies, such as the U.S. advanced technology division, which are used in a cone crusher, the German technology is applied in the impact crusher, and so on. Kefid Machinery draws attention to the invaluable experience inside and abroad. Thanks to the efforts of our engineers, many new equipment have been published, for example, mobile crushing plant on crawlers, hydraulic Impact Crusher, hydraulic cone crusher, and so on. In the declining trend in quality, Zhengzhou Kefid Machinery Co., Ltd. permanently and firmly adheres to this principle, to produce high quality products and provide provide excellent service to its klientam.Nesomnenno that Zhengzhou Kefid Machinery Co., Ltd. is a professional manufacturer in the industry for crushing and grinding equipment.

Gansu Park in China

The largest park, launched in 2010 in the U.S. – Park Roscoe capacity of 781.5 MW. Second Place – Park Horse Hollow Wind from 735.5 MW. The largest being built park is the Alta Wind Energy Center (800 MW). It should be noted the construction of the park Gansu in China.

Power Chinese fleet under the proposed project would be 10 GW. Other parks: Fowler Rigde (USA) – 600 MW (increasing to 750 MW); Penascal Wind Farm (United States) – 404 MW; Streator Cayuga Rigde South Wind Farm (United States) – 300 MW. Solar Station While most of the stations that use solar energy in 2010 was deployed in European countries, the leader for the year was the Canadian station Sarnia (97 MW). Then came the station Montalto di Castro (Italy, 84.2 MW) and Solarparke Finsterwalde (Germany, 80.7 MW). The largest geothermal plant Geothermal Station in 2010, was built in New Zealand. This is a project Nga Awa Purua capacity of 132 MW, which is the world's largest odnoturbinnoy geothermal station. The second power station was built in Italy in Larderello. The station consists of two blocks, each 20 MW: Nuova Radicondoli 2 and Chiusdino 1.

The third-power project – the second stage of the station in Kenya Olkaria II power of 35 MW. After increase the total installed capacity of 105 MW station. Bioethanol absolute leaders in terms of new capacities in the market of bioethanol in the past year were the United States and Brazil. These two countries accounted for 6 of 8 major projects in 2010. The largest new plants and bio-ethanol in the world in 2010 became the site in Iowa and Nebraska. The capacity of each of the projects is 300 million gallons per year and both of them have been implemented by ADM. Others Projects: Netherlands, Rotterdam – 126 million gallons (grain); USA, Texas – 115 million gallons of (corn), Great Britain, Tisayd – 106 million gallons (wheat), Brazil, Goias – 98 million gallons (sugar cane). Biodiesel and biofuel from waste in 2010 in Singapore, was launched into operation a plant capacity of 240 Nestle million gallons of diesel per year. The raw material is a mixture of palm oil, rapeseed and animal fat food. The second power plant – a project Dynmic Fuels in the U.S. with 75 million gallons per year. The plant works on animal fats procured from Tyson Foods.
