Supporting the development of parts of construction machinery manufacturing industry to build power – construction machinery, spare parts – construction machinery industry

?? XCMG Yang Lifu Xugong Group was established in March 1989, the annual income of 386 million yuan by the establishment and development to break through 30 billion yuan in 2007, the annual profits of 2 billion yuan, annual export break through 500 million U.S. dollars, in China Construction Machinery Industry ranking.

XCMG main products: construction lifting machinery, road machinery, road and maintenance machinery, Compaction Machinery , Shovel soil transport machinery, aerial fire-fighting equipment, special dedicated vehicles, special chassis for construction machinery construction machinery and other series Drive axle , Slewing bearings, hydraulic pressure products and other basic components, most of the domestic market share ranks first. 70% of the products for the domestic leading level, 20% of the products reach the international advanced level contemporary. Currently ranked No. 16 Construction Machinery Industry, China 500 No. 191, the first Chinese manufacturing 500 96.

XCMG through nearly two decades of development, the basic form to self-development and production of complete manufacturing system, its technical level and international advanced level is gradually narrowing the gap between. This high growth situation, bound to the component parts of construction machinery demand more and higher expectations.

1. XCMG supporting domestic and international situation

1.1 Status of domestic supporting

Now XCMG major domestic procurement of spare parts that have Engine , Hydraulic components, electrical components, drive axle, cab, etc., mainly on engine manufacturers supporting firewood, Weifang, Hangzhou hair, Dongfeng Cummins. There are high-pressure hydraulic parts Gear Pump , Cylinders, hydraulic hoses, valves, etc., the main vehicle wiring harness electrical components, switches, lamps, meters, etc..

Part of the structural parts, Xuzhou Construction Machinery Group after many years of technological transformation, the host of the large structure can be made to achieve some small structural parts such as tanks, weight, etc. As the technology less demanding, easily processed, lower production costs SME manufacturers can meet the quality and appearance of the design and use requirements, has a strong competitive edge. Therefore, the general choice for small structural parts outsourcing package.

1.2 Status of foreign package

XCMG current production of large-tonnage cranes, pump, Rotary Drilling Rig , Horizontal directional drilling, paving machines, motor graders, milling machines are used basically the core components imported. Euro imported engines, hydraulic pumps, Motor , Valves, gear, electrical components and other key components for the world's leading multi-product, mainly imported Cummins engine, Deutz, hydraulic components, mainly Rexroth, Sauer, Linde, reducer, etc. Transmission Parts There are Bangfei Li, Brevini, with its high technology products, reliable performance, stable quality, is the ideal accessories.

However, some basic conditions abroad such as: hydraulic pumps, valves, motors, running gear and other key parts procurement cycle is too long, and some even up to a year, has seriously affected the progress of production to create a larger company economic losses.

2. On the understanding of internal fittings

Internal fittings and the world most advanced level there is a big gap, mainly in the species was incomplete, complete sets of matching ability, low level of mechanical and electronic integration. Particular variable variables needed to pump hydraulic system, variable hydraulic motors and other variable components and high level of mechanical and electrical integration, high-tech hydraulic components basically blank, multiple valves, reducers, hydraulic mechanical transmission components and other high-level domestic basic can not be produced, thanks to demand for imports.
