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.
Characteristics and scope of application of common bulldozer
(1) Crawler type: This type of bulldozer has the advantages of large adhesion traction and strong climbing ability, and can be competent for more sinister working environment. It is a representative type of bulldozer and is widely used in all kinds of earthwork projects;

In summer, tractor maintenance needs to pay special attention to the following aspects:
1. Clean cooling system
Regularly clean the debris, dust and dirt on the water tank, radiator and fan to ensure a good heat dissipation effect.
2. Check cooling system
Ensure that coolant is sufficient and of good quality to prevent engine overheating. Replace the coolant if necessary.
3. Maintain the air filter
There is more dust in the air in summer, and the air filter should be checked and cleaned frequently to prevent poor intake.
4. Tire maintenance
Pay attention to the tire pressure to avoid too high or too low pressure. Too high air pressure is easy to blow a tire at high temperature, and too low will increase tire wear.
5. Electrical system inspection
Check the wires for damage, aging or poor contact to prevent short circuits and fire.
6. Lubrication system
Replace and add lubricating oil as required to ensure that all components are well lubricated.
7. Fuel system
Clean the fuel filter regularly to prevent impurities from clogging the oil line.
8. Parking and protection
Avoid the tractor being exposed to sunlight for a long time and can be parked in a cool and ventilated place. If possible, use car clothing for protection.
9. Check brake system
Ensure good braking performance, timely adjustment and replacement of worn brake components.
10. Regular engine maintenance
Perform regular engine maintenance according to the requirements of the user manual, including checking valve clearance, spark plug, etc.
In short, the maintenance of tractors in summer is very important, and the maintenance measures can be carefully done to extend the service life of tractors and improve work efficiency.

In recent years, foreign market demand for road roller is increasing, China’s road roller export scale is expanding, as domestic road roller enterprises continue to increase investment in research and development, the future domestic enterprises will occupy a dominant position in the global market competition, the industry development prospects are broad.
Road roller is a kind of machine that uses the mechanical weight and vibration method to repeatedly load the compacted material, force the material particles to wedge each other, so as to achieve a certain degree of compactness and flatness. According to the different quality of work, the roller can be divided into light, small, medium, heavy roller; According to the different compaction principle, can be divided into static pressure type, vibration type, impact type roller; According to the different roller, the static roller can be divided into single steel wheel roller, double steel wheel roller. Road roller is an important compaction mechanical equipment in road construction, which can be used in expressway, railway, airport runway, dam and other scenarios, and is widely used.
In recent years, with the continuous increase of domestic infrastructure investment, road roller as one of the important construction machinery, its market sales show a fluctuating upward trend. According to the data of China Construction Machinery Industry Association, the sales volume of domestic road rollers in 2020 was 19,479, up 14.7% year on year; The sales volume of road rollers in 2021 was 19,519 units, up 0.2% year on year. From the market segment point of view, in 2021, hydraulic single steel roller is the largest market share of domestic roller, 29.8%, followed by light roller and mechanical single steel roller, market shares are 24.5% and 24.3%, respectively, the three accounted for 78.6%, is the current domestic mainstream roller models.
Large roller is widely used in filling and compaction of high-grade highways, railways, airport runways, DAMS, stadiums and other large engineering projects. Its advantage is strong work quality and high efficiency, but for users, it is the most concerned problem to reduce fuel consumption without affecting the work.
1, choose the appropriate driving speed, not overspeed driving.
2, the locomotive load should be appropriate. Practice has proved that the load of about 85% is the most fuel-efficient and economical, so as not to waste oil.
3，Keep the performance of electrical system and starting mechanism intact. Do not idle the engine for a long time, stop immediately flameout.
4, reasonable selection of mechanical equipment. Proper planning of driving routes, as far as possible to reduce 4 tons of roller idling, empty driving, circuitous, stop in the middle, shorten the total distance of operation, reduce ineffective energy consumption.
5, keep the normal working temperature of the engine, especially in the cold season, try to keep the water temperature at 75-90℃, and use oil according to the season.
6，Regularly remove scale of cooling system, oil scale and sediment of pipeline and muffler.
7，Carry out technical maintenance in a timely and reasonable manner to keep all parts and mechanisms in good technical condition.
8, correct adjustment of the brake, often check the large roller front and rear wheels, keep the tire pressure normal.
9, purify oil, measurement of refueling. If without precipitation filtration before use, impurities in the oil will bring harm to the plunger and needle valve couple, so that the locomotive power decreases and fuel consumption increases. Therefore, general oil should be precipitated for more than 48 hours of reuse.
10，Prevention of oil leakage. Because the roller has been used for a long time, there will be poor contact, improper assembly, mat damage, screw loosening, pipe deformation or rupture, aging seal ring, will cause oil leakage. Therefore, corresponding countermeasures must be taken to timely plug the leak and save oil.
At present, intelligent construction machinery is one of the main research directions of major manufacturers and research institutions. There are many technical obstacles in the research and development process, and there is a long way. According to bauma Munich, topics related to intelligent construction and connected data computing will be the focus of industry discussion in 2022.
In order to achieve partial automation in more complex construction machinery construction sites, it is essential that different brands of equipment can communicate data and information to each other. To this end, the German association of machinery and equipment manufacturing industry and Germany are actively promote construction industry association, in order to make future construction site to more self-independence of digital, intelligent and way of operation and management, from the most basic equipment “starting/stopping” began, the running status of equipment and so on all need to implement standardization of data information. This cross-machine collaboration allows construction operations to multi-task in parallel and, ideally, cut construction time in half.
