The walking characteristics of wheeled tractor

（一）Features:

1.Good maneuverability, fast speed, flexible steering, suitable for all kinds of terrain and working environment.

2.The pressure on the road surface is relatively small, and it is not easy to damage the road surface.

3.Maintenance costs are low and tire changes are relatively easy.

（二）constituent part:

1. Front wheel: Mainly used for steering, usually small, with a certain steering Angle.
2. Rear wheels: provide traction, generally larger and wider, to increase the contact area with the ground and improve traction.
3. Frame: Connects the front and rear wheels and supports the weight of the entire tractor.
4. Suspension system: including springs, shock absorbers, etc., used to reduce vibration during driving and improve ride comfort.

The engine of a tractor may have a variety of failures during use, and the following are some common types of failures:

1. The startup is difficult or cannot be started

Causes: insufficient battery power, starting circuit failure, fuel system blockage, ignition system failure, internal mechanical failure of the engine, etc.

Performance: After pressing the start button, the engine does not respond or rotates slowly, and cannot start normally.

2. Insufficient engine power

Causes: insufficient fuel supply, air filter blockage, insufficient cylinder pressure, fuel injector failure, engine overheating, etc.

Performance: When the tractor is driving or operating, the power decreases significantly, the acceleration is slow, and even the tractor cannot run normally.

3. Engine overheating

Reasons: cooling system failure (such as insufficient coolant, radiator blockage, water pump failure, etc.), excessive engine load, insufficient oil or deterioration.

Performance: The water temperature indicator on the instrument panel is too high, the engine surface temperature is abnormally high, and even the phenomenon of “boiling” appears.

4. Abnormal engine noise

Reasons: crankshaft bearing wear, piston and cylinder clearance is too large, improper valve clearance, loose transmission belt, etc.

Performance: The engine emits abnormal sounds during operation, such as tapping, friction, buzzing, etc.

The overseas market of construction machinery shows a diversified and continuous development trend.
In recent years, the global construction machinery market has continued to grow, especially in emerging economies and developing countries, and the demand for infrastructure construction is strong, which has promoted the demand for construction machinery.
From a regional perspective, the Asia-Pacific region is one of the largest construction machinery markets, and large-scale infrastructure construction projects in China, India and other countries have driven market demand. The market in Europe and North America is relatively mature, but the demand for high-end, environmentally friendly construction machinery is still stable. With the advancement of energy development and infrastructure construction in the Middle East and Africa, the demand for construction machinery is also gradually increasing.
In terms of products, excavators, loaders, cranes, bulldozers, etc. are the main demand products in overseas markets. Among them, the excavator market share is large, because it is widely used in earthmoving engineering, building construction and other fields.
With the recovery of the global economy and the promotion of infrastructure construction, the overseas market of construction machinery is expected to continue to grow, but it also faces challenges such as intensifying market competition, trade protectionism, and differences in technical standards.

Chinese bulldozers have the following competitive advantages in overseas markets:
1. Cost-effective: On the basis of ensuring product quality and performance, the price is relatively reasonable, which can provide customers with more cost-effective choices.
2. Continuous improvement of technology: Through continuous research and development investment and technological innovation, China’s bulldozers have gradually caught up with the international advanced level in technology, such as intelligent control, energy conservation and emission reduction and other fields have achieved certain results.
3. Customization capability: We can provide customized products and solutions according to the specific needs and operating environments of customers in different regions to better meet the individual needs of the local market.
4. Rapid response after-sales service network: The establishment of a relatively complete global after-sales service system, can respond to customer needs in a timely manner, provide rapid and effective repair and maintenance services, reduce customer costs and risks.
5. Rich product line: Covering different specifications, power and functions of the bulldozer products, to provide customers with more choices.
6. Strong production capacity: with the ability of large-scale production, can meet the large demand of the market in time to ensure the stability of product supply.
7. Adapt to diverse working conditions: for different construction conditions and working conditions, targeted design and optimization, so that it can work efficiently in a variety of complex environments.

Bulldozer overseas market prospects are broad, mainly reflected in the following aspects:

Market demand growth: With the development of the global economy and the continuous advancement of infrastructure construction, the demand for bulldozers in construction, mining, road construction and other fields continues to grow. Especially in emerging markets, such as Southeast Asia, Africa and other regions, the demand for infrastructure construction is more vigorous, providing a huge development space for the bulldozer market.

Technology upgrading: As technology continues to advance, the technology of bulldozers is also constantly upgrading. For example, the application of intelligent and automated technology makes the operation of the bulldozer more simple and efficient, and improves the construction quality and efficiency. At the same time, the application of environmental protection and energy-saving technology is also in line with the trend of global sustainable development, and is favored by more and more users.

The rise of Chinese brands: The competitiveness of Chinese bulldozer brands in technology, quality, cost performance and other aspects continues to improve, and gradually emerges in the international market. The export volume of Chinese brand bulldozers is increasing year by year, and the market share is also expanding.

Of course, the bulldozer overseas market also faces some challenges, such as fierce market competition, trade protectionism and so on. But in general, the bulldozer overseas market prospects are still broad, with greater development potential.
