With the continuous advancement of domestic tunnel excavation, urban renewal, highway maintenance and other projects, the demand for precise excavation and green construction under complex geological conditions has become increasingly prominent. Traditional construction equipment often faces pain points such as high vibration, low precision and severe pollution when working in medium and low hardness rock formations, frozen soil, reinforced concrete and other scenarios. Recently, Shandong Zhongju Intelligent Equipment Co., Ltd. accurately identified industry needs and launched a new series of excavator-mounted milling machine attachments. Boasting core advantages of low vibration, low noise, precise control and wide adaptability, this product can efficiently replace traditional equipment such as buckets and hydraulic breakers, providing an efficient and environmentally friendly solution for diverse complex construction scenarios and attracting widespread attention in the industry.
Core Technological Breakthroughs: Low Vibration, Precision, Durability and Adaptability Solve Construction Pain Points
Zhongju's excavator-mounted milling machine has achieved multiple breakthroughs in technological research and development, accurately matching the construction needs of complex working conditions. In terms of operational performance, the product is equipped with a low-speed, high-torque hydraulic motor direct drive system, combined with a high-strength wear-resistant cutter head design. It can easily handle medium and low hardness rock formations such as weathered rock and tuff, as well as materials such as frozen soil and concrete without or with a small amount of steel reinforcement. The milling efficiency can reach 25-40 m³/h. When working in special formations such as clay, it can effectively avoid the problem of the cutter head being wrapped, ensuring continuous construction. Its optimized mechanical structure design significantly reduces vibration and noise during operation, allowing safe work in areas with vibration and noise restrictions such as around ancient buildings, hospitals and core urban areas. It can effectively replace traditional blasting construction, minimizing the impact on the surrounding environment and structures.
Precise control is another core highlight of this product. Zhongju's milling machine is equipped with a high-precision control system, which can realize 360-degree all-round rotating operation and quickly and accurately trim the contour of structures. Whether it is under-excavation trimming and inner surface grooving in tunnel excavation, or pavement milling and gutter excavation in road reconstruction and expansion, it can achieve clear and accurate excavation contour lines, effectively solving the cost increase problem caused by the traditional construction principle of "prefer over-excavation to under-excavation". At the same time, the milled materials have small and uniform particle sizes, which can be directly used as backfill without secondary crushing, greatly improving construction efficiency and reducing material processing costs.
Zhongju's milling machine performs excellently in adaptability and durability. The product can flexibly adapt to various brands of excavators ranging from 0.8 to 50 tons. Through a standardized hydraulic interface design, installation can be completed using the excavator's original hydraulic circuit without the need to purchase additional power equipment, making installation and disassembly convenient and efficient. Its super-strong shell and gearbox design greatly extend the service life, and maintenance is simple, without the need for frequent greasing and nitrogen charging, significantly reducing equipment operation and maintenance costs; it can even work 30 meters underwater, further expanding the boundary of application scenarios.
Diverse Scenario Coverage: Empowering Multi-Field Construction, Aligning with Green Development Trends
Relying on excellent product performance, Zhongju's milling machine has achieved full coverage of multi-field applications, accurately matching the core needs of current engineering construction. In the field of tunnel engineering, this product can be directly used for the excavation of tunnels in medium and low hardness rock formations, and can also specifically solve problems such as tunnel contour correction and under-excavation trimming. The excavation process has little disturbance to the stratum and high safety, making it particularly suitable for areas where blasting construction is not advisable, effectively improving the efficiency and safety of tunnel construction. In urban renewal and municipal engineering, it can be widely used in underground pipeline trench excavation, concrete pavement milling, building demolition and other operations. Its low vibration and low noise characteristics are perfectly suitable for urban construction environments, avoiding interference with the lives of surrounding residents.
In addition, this product can also be efficiently used in scenarios such as open-pit coal mining, slope trimming, river channel improvement and frozen soil construction. Cooperating with excavators to achieve integrated operations such as milling and loading, one piece of equipment can meet the needs of multiple working conditions, greatly improving construction convenience. Under the background of the advancement of the "dual carbon" strategy, the environmental protection advantages of Zhongju's milling machine are particularly prominent. Replacing traditional blasting construction can reduce dust and noise pollution, and the direct reuse of milled materials can reduce resource waste, fully complying with the industry development trend of green construction.
Broad Market Prospects: Accelerated Domestic Replacement, Technological Innovation Leads Industry Upgrade
Currently, China's construction machinery industry is accelerating its evolution towards intelligence, greenization and localization. As a key equipment in the field of precise excavation, the market demand for milling machines continues to rise. According to relevant industry data, benefiting from the continuous advancement of highway maintenance, urban renewal, tunnel construction and other projects, the scale of the domestic milling machine-related market maintains steady growth. Domestic equipment, relying on cost-effectiveness advantages and technological innovation, has continuously increased its market share, and the trend of domestic replacement has become increasingly prominent.
Industry experts said that traditional milling equipment mostly relies on imports, with problems such as high prices and slow after-sales response. The launch of Zhongju's excavator-mounted milling machine not only fills the demand gap of small and medium-sized engineering enterprises for cost-effective milling equipment, but also can provide fast technical support and after-sales guarantee relying on local R&D and production advantages. Relying on the advantages of the construction machinery industry cluster in Jining, Shandong, Zhongju has built an efficient supply chain system, which can realize rapid product delivery and further enhance market competitiveness.
A relevant person in charge of Zhongju Intelligent Equipment said: "Accurately grasping industry development trends and empowering construction upgrades through technological innovation is our core development philosophy. The newly launched milling machine series products are the technological crystallization of the company's years of in-depth cultivation in the attachment field. In the future, we will continue to increase R&D investment, promote the intelligent upgrading of products, develop more milling machine products suitable for high-end complex working conditions, and expand overseas markets at the same time, allowing China's intelligent milling equipment to go global and contribute to the high-quality development of global engineering construction."
**Conclusion**: Today, as engineering construction has increasingly high requirements for precision, efficiency and environmental protection, the launch of Zhongju's excavator-mounted milling machine provides a new and efficient solution for complex working condition construction. It not only demonstrates the technical strength of domestic construction machinery attachments, but also will promote the industry upgrading in the field of precise excavation. With the continuous deepening of market applications, Zhongju Intelligent Equipment is expected to make continuous breakthroughs in the milling machine segment and create value for more engineering construction enterprises.
