Drum Cutter Excavator Advantages
A high-performance drum cutter excavator relies on its internal core technologies, which guarantee outstanding performance even under tough working conditions.
- Strong power and reliable transmission: Equipped with imported high-torque hydraulic motors and high-strength spur gears, it delivers powerful and stable cutting force, ensuring efficient work even in rocks with compressive strength up to 90 MPa.
- Excellent sealing and durable bearings: Key components adopt imported bearings and oil seals, significantly extending the service life of the equipment while also enabling superb underwater operation capability.
Unique Features of Excavator Drum Cutter Design
Compared with ordinary drum cutters, this excavator drum cutter introduces a major innovation in drum head design, which directly determines work efficiency and cutting results.
- Achieve precise trench milling: Its unique no-blind-zone design eliminates the central gap found in conventional drum heads, allowing for smooth, continuous grooves without side-to-side swinging. The groove width never exceeds the cutter head width, ensuring high precision.
- Improved efficiency and smoothness: This design reduces operator workload, enables faster feed rates, and achieves smoother cutting surfaces—especially ideal for tunnel profiling and road milling where high accuracy is required.
Wide Application Fields
As a multifunctional attachment, the drum cutter attachment is widely used in projects that require precise milling.
- Tunnels and municipal works: Ideal for trenching, tunnel excavation, and profiling, it offers precise non-blasting excavation with minimal disturbance to surrounding structures, ensuring safety.
- Mining and demolition: Used in mines to separate ore and in demolition projects to cut reinforced concrete with precision. Its controllability surpasses traditional breakers, making it suitable for selective demolition.
Key Considerations When Choosing Milling Head for Excavator
Selecting the right milling head for excavator is the first step to successful application, and several factors must be considered.
- Equipment compatibility: The cutter size must match the excavator’s tonnage, hydraulic flow, and pressure. For example, the 25 Type suits 20–28T excavators, while the 35 Type is better for 30–40T carriers to ensure optimal performance and avoid equipment damage.
- Model selection based on jobsite: For wide trenching, the 35 Type with an 800 mm width is more efficient. In tighter spaces requiring flexibility, the 25 Type is more suitable. Additionally, always consider material hardness to ensure torque is sufficient.
Investment Value
Investing in a high-quality milling head for excavator can immediately boost project performance and overall profitability.
- Safety and cost-effectiveness: It provides a non-blasting construction method, greatly improving jobsite safety, while its efficiency reduces machine operating hours and labor, delivering significant ROI.
- Multi-functionality and eco-friendly operation: One machine replaces multiple tools, reducing overall equipment costs. With low vibration, low noise, and minimal dust, it complies with modern environmental standards and is highly suitable for urban construction.
The drum cutter attachment is a revolutionary tool in modern construction, transforming excavators into precise milling platforms.
