On the development trend of domestic wheel loaders

  • Detail

Talking about the development trend of domestic wheel loaders

in a long time in the future, wheel loaders will still be one of the most important types of engineering construction machinery. The domestic annual demand will continue to be stable at about 20000 units, but the domestic loader manufacturers are expanding rapidly, and the competition is becoming more intense. All manufacturers have developed new products to meet the challenges of the market

1 market prospect of wheel loaders

1.1 market demand analysis

(1) international market

the world's transportation, energy and other infrastructure undertakings are developing rapidly, with an annual investment of hundreds of billions of dollars. At present, the total annual output of loaders in the world has reached 150000. The United States, Japan and Western Europe are the main producing countries and regions of loaders, with an annual output of more than 10000, including 46000 in the United States and 29000 in Japan. The world sales of construction machinery has reached 45billion US dollars and is expected to reach 50billion US dollars by 2000. Among them, the United States accounts for 40%, Japan 35%, and the rest are the European Union and other countries

(2) the domestic market

affected by national policies and investment directions, the development trend of the domestic market in the next 5 to 10 years is:

from a regional perspective, the market demand of Anhui, Henan, Jiangxi and other regions is rising, and the national policy of investment in the central and western regions will also make the market in this region have broad prospects

from the perspective of users, the State encourages the coexistence of various economic forms, and the market demand of private economy and individual users is still rising; The national large-scale engineering construction has increased the demand for large tonnage loaders and other engineering construction machinery

1.2 market risk of domestic wheel loaders

with the rapid development of the excavator industry, the demand for loaders in earthwork engineering is partially replaced by excavators; The state strengthens the protection of resources and environment, rectifies the structure of the coal industry, restricts the mining of small coal mines, and affects the demand of the coal mine system for loaders; The turnover and loading and unloading of bulk materials in cargo stations and ports tend to be large-scale and automated, which restricts the demand for loaders

1.3 impact of national tariff and trade policies and regulations

since January 1, 1998, imported equipment for domestic and foreign-funded projects encouraged by the national industrial policy has been exempted from tariffs and import value-added tax, including wheel loaders of 5M3 and above

the total tariff level in China has decreased from 35.9% to 23%, of which the construction machinery has decreased from 15.7% to 13.6%, which will affect the production of loaders above 6 tons in China

2 competitors faced by wheel loader manufacturers

2.1 foreign competitors

products produced by caterpillar of the United States represent the technical level and development direction of engineering construction machinery in the world today, ranking first in the world; The international top Laboratory of injectable ceramics in Japan has realized the preparation technology of porcelain, degradable fixing materials and new low modulus titanium alloy, such as rat mind pressure bar, monkey mind feeding and human brain electronic control manipulator grasping chocolate; Bone repair materials such as medical magnesium alloy, spinal repair materials, functional bionic artificial joints, surface biological functionalized artificial joints and their preparation technology; Komatsu, a powerful competitor of caterpillar, followed closely by bone lure functional artificial bone and functional bionic artificial bone preparation technology; Western Europe is the third largest group in the production of loaders. It has famous companies such as Fiat of Italy, ARIS, Volvo of Sweden, Liebherr of Germany, O & K, caitmann and JCB of Britain. At present, these engineering construction machinery manufacturers have fully entered the Chinese market, mainly forming a monopoly on loaders of more than 6 tons, and will not pose a great threat to China in small and medium tonnage loaders. However, foreign manufacturers are studying the characteristics of the Chinese market, developing new products suitable for China's national conditions, and further expanding the market share of their products

2.2 domestic competitors

there are nearly 90 loader manufacturers nationwide, including more than 30 professional manufacturers, with a total industrial output value of more than 3 billion yuan. The main manufacturers are: Liugong, Xiagong, Xugong, Changlin, Chenggong, Yichong, Shangong, etc. these manufacturers have long experience in loader production, strong strength, high market share and good after-sales service. They have always established a good image in the eyes of users and maintained their existing status and advantages. Its large investment in technological transformation during the "Eighth Five Year Plan" and "Ninth Five Year Plan" has gradually brought into play its effectiveness and role, making the enterprise glow with vitality and vigor

the locations of domestic manufacturers are more aware of the huge market and benefits of loader, and they have listed it as a pillar industry to support and give preferential policies. The joining of a number of new members, such as Longyan in Fujian and Mengling in Shandong, has a rapid development momentum and more intense competition

after the international first-class companies Komatsu, Liebherr and Volvo established joint ventures in China, the possibility of Caterpillar's joint venture or wholly-owned production of loaders has increased, intensifying the competition in the domestic market

3 analysis of the current situation of domestic wheel loaders

all manufacturers do not have their own fist products, their own key technologies and strong technical innovation teams, low-grade leading products, heavy burden on enterprises, and high production costs

3.1 loaders below 3T

products below 3T are mainly represented by ZL10, ZL15 and zl16. There are also some small loaders modified by tractor chassis, which are mainly used in conjunction with an increasing number of agricultural transport vehicles. The main parts and components are engines, drive axles, gearboxes and hydraulic parts with general performance and quality. Hydrostatic transmission products with advanced technology are difficult to match in China, and the product cost remains high, which restricts the development of this kind of products in China

3.2 ZL30 loader

zl30 loader is mainly produced by Chenggong, Changlin, XCMG, Yichong, Shangong, etc. The configuration of parts and components of this product is relatively messy. The manufacturer has self-made bridge boxes, with distinctive styles, relatively stable quality and performance, and general technical progressiveness. The TPE material recently developed by XCMG is a heat shrinkable elastomer ZL30F loader with full closed hole structure, which adopts an electric shift gearbox, making a new breakthrough in the technology of 3T loader

3.3 ZL40/ZL50 loader

zl40/ZL50 loader, which is owned by major loader manufacturers. The first generation of products has continued for decades, and almost the same set of drawings are used throughout the country. Some manufacturers with weak technical strength still take them as leading products to the market. The second and third generation products mainly optimize the working device and change the appearance. Such as Liugong ZL40B/ZL50C, XCMG zl40e/ZL50E. On the basis of the third generation, the fourth generation products further optimize the performance and configuration of the whole machine. New technologies such as electric cabinet and wet brake have been applied, and the proprietary technology and patented technology of various enterprises have been formed, so that the products can be introduced to the market with a new face

3.4 ZL60 and above loaders

6t and above loaders are the largest products in the domestic potential market. Before 1998, most manufacturers developed ZL60 loaders, but due to the restriction of transmission parts, ZL60 loaders failed to be successfully introduced to the market. At the '99 Beijing International Construction Machinery Expo, various manufacturers launched a new generation of ZL60 loaders. Most manufacturers choose the boxes or bridges jointly produced by Liuzhou ZF. The hydraulic components also have new configurations. The engine can choose Steyr or Shangchai 6121 (cat3306). The reliability of the whole machine has been greatly improved, bringing development opportunities to domestic large tonnage loaders

4 development trend of domestic wheel loaders

domestic wheel loaders are transitioning from low-level, low-quality, low-cost, functional type to high-level, high-quality, medium price, economic and practical type. In the transition from imitation to independent development, major manufacturers continue to invest in technology, adopt different technical routes, and make technological innovation in key components and systems, get rid of the current situation of similar product design without their own characteristics and advantages, stand out from the strange circle of low-level disorderly competition, and become the leader of the loader industry

(1) during the development of large and small wheel loaders in recent years, they are limited by objective conditions and total market demand. The most competitive medium-sized loader will be updated faster and faster

(2) according to the actual situation of each manufacturer, carry out the overall design again, optimize various performance indicators, strengthen the strength and stiffness of structural parts, and greatly improve the reliability of the whole machine

(3) refine the system structure. Such as vibration reduction of power system, structural optimization of heat dissipation system, performance index optimization of working device, dust prevention of each hinge point, industrial modeling design, etc

(4) use electronic technology and load sensing technology to realize the automatic shift of gearbox and the application of hydraulic variable system, improve efficiency, save energy and reduce the operating cost of loader

(5) improve safety and comfort. The cab will gradually have the function of FOPS & ROPS. The environment in the cab will be close to the direction of the car. The steering wheel, seat and each joystick can be adjusted to make the operator work in the best position

(6) reduce noise and emissions and strengthen environmental protection indicators. With the enhancement of people's awareness of environmental protection, it is imperative to reduce the noise and emission of loaders. Now many big cities have formulated the noise and emission standards of motor vehicles. If the construction machinery does not meet the emission standards, it will be limited to the sales in this area

(7) make extensive use of new materials, new processes and new technologies, especially the mechanical, electrical and hydraulic integration technology, to improve the service life and reliability of products

(8) simplify maintenance to the greatest extent, minimize maintenance times and maintenance time, increase maintenance space, generally adopt electronic monitoring and monitoring technology, further improve the fault diagnosis system, and provide drivers with methods to eliminate problems
