Backhoe loader development and trends

First: The Backhoe loader domestic competitors are divided into:

① export: such as Sichuan Road Machinery Plant produced more than 80% multi-function engineering machinery are exported, and always find a good addition, Guilin Forestry Machinery Factory specializes in the production of small crawler loader, most of the export product.

② into parts abroad, the domestic assembly-type: such as Shanghai, CASE of the 580/590 series. Imported, domestic agent-type: such as JCB’s 2CX/3CX/4CX; VOLVO the B160/B171; CASE of 580/590 and so there is now a proxy.

③ domestic production enterprises: more than 10 domestic manufacturers, their products are low-end of the backhoe loader. Price: 380 thousand yuan or less. Therefore, the backhoe loader is the development trend of domestic introduction of foreign advanced technology, developing high-quality, multi-function, multi-varieties and specifications of the backhoe loader series of products to enhance the basic components, parts production, particularly to improve the Backhoe Loader The quality hydraulic components to meet the product reliability to meet under the premise of reducing product cost of backhoe loaders and Backhoe loader products to improve service levels.

Second: gaps and development requirements at home and abroad

As the Backhoe loader started late in China, both in product variety, performance parameters and reliability, after-sales service and so on, are compared with foreign countries there is a considerable gap. Performance in:

Backhoe loader made in China are mainly accessories reliability as abroad. There are reliability problems: diesel engine, hydraulic components, hydraulic system cleanliness, transmission components, electrical systems and electrical components, fastening technology and sealing technology, tires and operating devices. Backhoe Loader poor product performance, low reliability. In addition in recent years, some products from abroad, the domestic part of the backhoe loader product’s performance is still at the level of 90 international 20th century, early high failure rate, can not fully meet the requirements of road construction. Backhoe Loader basic components of poor quality, parts quality, but hard. At present, the domestic cylinder engine and hydraulic systems, pumps, valves and other quality has restricted the backhoe loader product quality “bottleneck.”

Backhoe Loader few varieties, poor sets, the model was incomplete, some products do not form a series. Our backhoe loader models in terms of varieties and respect a lot, there are still gaps.

The lack of existing backhoe loader product innovation and unique technology. China Backhoe Loader lack of research and development of innovative, not have their own unique technology. When introduced in the emphasis on technology and less emphasis on assimilation, and mastery of key technologies and research. Therefore, the development of domestic backhoe loader should develop high-quality, multi-functional, multi-species, multi-standard products, and strengthen the basic components, parts production, particularly to improve the quality of hydraulic components to meet the product reliability in meeting the premise of reducing product costs and improve product service levels.

Third, development and the development of several issues Backhoe Loaders

1, backhoe loaders is the management of special equipment

Countries to strengthen and regulate the safety involved, more dangerous special equipment managed to adapt to market after China’s accession to WTO international requirements of a reasonable, legitimate use of trade rules, protecting the interests of countries and peoples, enacted in 2003 implementation of the “Special Equipment Safety Supervision Regulations” (State Council Decree No. 373), “Implementation of Administrative Licensing of special equipment (for Trial Implementation)” (National Quality Inspection pot 〖2003〗 172) and other series of laws and regulations. At the same time the State General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ hereinafter) under the “Special Equipment Safety Supervision Regulations” and “special equipment to monitor quality control and safety requirements” (State Administration of Quality and Technical Supervision Order No. 13) developed “Electrical and special equipment manufacturing license Rules (Trial Implementation)” (State Quality Supervision, Inspection pot [2003] 174), to regulate the machinery and electronic special equipment manufacturing license, to ensure the manufacture of machinery and electronic special equipment quality and safety and technical performance.

According to the paper the implementation of the requirements to be included in special equipment, such as licensed products catalog loader, loader, used excavator, hoisting machinery, special equipment for some products included in the management of June 1, 2004 to obtain the corresponding manufacturing license, or business will not engage in the production and sales. Currently, the plant contained in motor vehicle equipment type, product type provides the most clear that the “special equipment manufacturing license Electrical Code (Trial)”, which provides special equipment manufacturing license directory, will now belong to the factory equipment, motor vehicles types and the corresponding equipment type was defined (see table below), this should be the future basis for the management of motor vehicle factory.

According to relevant laws and regulations, in our country’s foreign sales of special equipment manufacturing, their products are required to meet the special equipment of the laws, administrative regulations, rules, mandatory standards and technical specification requirements. At the same time accept the Authority and type testing. Since backhoe loaders have not previously included in the real management of special equipment, so the foreign mining loader products can freely enter and leave the technical and management without any restrictions and supervision, but the domestic mining loader products for type testing and have to accept some parts of quality supervision departments of supervision and inspection, the same products have been treated differently. Special equipment such as Backhoe loader production and development of manufacturing companies, top priority is to make the request in accordance with technical, production and management products and preparations, active applications, to obtain qualified domestic production. And use it as Figure machine, increase product improvements, and actively carry out international standards and foreign advanced standards, and enhancing product quality and technical level, to meet international market demand.

2, backhoe loader product positioning

① backhoe loader product positioning: the enterprise is concerned: there should be enhanced backhoe loader market predictability, improve market responsiveness Backhoe loader, backhoe loaders and timely market information collection, control backhoe loader market trends at the same time, strengthen enterprise The backhoe loader new product development efforts, can enterprises in the fierce market competition, the first to seize the market, Yong Li position, the path of sustained development. Western developed countries, construction machinery manufacturers out of the blind early stage, no matter what products they are developing will have a clear market positioning, for different consumer groups to produce different products in the development of small developing countries such as China Construction Machinery , product positioning must be prospective. Should use different techniques for different user base to solve the accurate positioning of the problem, China should first target the rural and coastal areas supporting the use of classification for the project construction machinery products development of small projects, this is the characteristics of the diverse social structure manifestation of structural changes affecting demand.

At present, the enterprise should be based on our own strength, first pinpoint their location, determine the production of that product; then pulse for the product, decide how to produce. Quasi-market companies must grasp the pulse of the development time to adjust their thinking, another reasonable use foreign advanced experience, for the Chinese market and self-development with Chinese characteristics, a small engineering machinery products, you can also engage in joint development with foreign companies. Small products to highlight the low-cost, practical, large user base, clear. Continue to do fine, well-led Xugong existing products, and the development of the market, combining the business advantages, to develop more marketable products for small construction machinery.
