轮式挖掘机市场增长，技术

Wheel excavators, with their unique mobility and flexibility, are becoming indispensable core equipment in the field of construction machinery. Compared to crawler models, which are more restricted by terrain, the wheeled chassis allows for quick transfers and flexible adaptation to various complex working conditions.

In recent years, with the deepening of infrastructure construction and technological iterations, the market demand for wheel excavators has been continuously rising, and the market size has been steadily expanding, becoming an important engine driving industry growth. It is expected that by 2026, the market size of wheel excavators in China will reach 150 billion yuan, with a year-on-year growth of about 8%, accounting for more than 50% of the global market share, showing strong development momentum.

In terms of product structure, wheel excavators can be divided into three categories based on tonnage: small, medium, and large, forming a well-structured and widely covered product matrix. Among them, small wheel excavators (0.5 to 10 tons) dominate operations in narrow spaces such as agriculture, landscaping, and municipal maintenance due to their compact and flexible advantages. It is expected that sales will reach 60 billion yuan by 2026, with a year-on-year growth of 6%.

Medium excavators (10 to 20 tons) strike a balance between operational efficiency and site adaptability, widely used in scenarios such as port loading and unloading, and road maintenance, with expected sales of 80 billion yuan. Large equipment over 20 tons focuses on high-intensity operations such as mining and large-scale infrastructure construction, with expected sales of 10 billion yuan and a year-on-year growth of 9%. This differentiated product combination effectively supports the diverse application needs of various industries.

Technological innovation is the core engine for the high-quality development of wheel excavators. Currently, high-pressure common rail technology is widely used in domestic models, accounting for 80%, effectively improving fuel economy; some models reduce fuel consumption by 15% compared to traditional products.

Meanwhile, the penetration rate of electronic control systems has reached 90%, achieving precise control of core systems such as hydraulics and power, significantly enhancing the intelligence level of the equipment. Some high-end models integrate advanced functions such as remote monitoring and fault self-diagnosis, with sales of intelligent excavators expected to grow by 20% year-on-year by 2025.

In the environmental protection field, the introduction of after-treatment technologies such as selective catalytic reduction has enabled equipment emissions to reach Euro V or even Euro VI standards, with sales of green models rapidly increasing, becoming a new market highlight.

In terms of application scenarios, wheel excavators are continuously enhancing adaptability and expanding service fields. In urban construction, they can flexibly shuttle through narrow streets to complete pipeline laying and foundation construction; in agricultural production, their wheeled design reduces soil compaction, suitable for land leveling, trench digging, and other operations; in emergency rescue, some models have a maximum speed of over 80 km/h and a wading depth of 1200 mm, allowing them to quickly reach the front line for road repairs, obstacle removal, and hazard elimination.

Furthermore, with the continuous advancement of the "Belt and Road" initiative, wheel excavators are gradually becoming important equipment for overseas projects, showing broad international market prospects.

From a competitive perspective, the current wheel excavator market presents a diversified parallel pattern. Domestic brands, with their continuously improving independent research and development capabilities and market responsiveness, occupy about 65% of the market share, firmly controlling the mainstream mid-end market, while foreign brands maintain a certain technical advantage in the high-end field.
