AM2200S Large Asphalt Mill Machine

Expert Review:
The AM2200S asphalt mill machine is a large-scale construction machine specifically designed for the maintenance and renovation of asphalt concrete pavements. It is mainly used for large-area milling operations on asphalt surface layers in scenarios such as highways, urban and town roads, airport runways, large freight yards, and parking lots. This equipment can efficiently remove common pavement distresses such as upheavals, oil waves, network cracks, and ruts; it can also precisely excavate pavement potholes and trenches; and it is suitable for roughening cement pavement surfaces and milling uneven slab joints. It is a key piece of equipment for realizing the recycling and reuse of pavement materials and promoting the concept of green road maintenance.

Applicable Conditions:
Highways
Municipal and town roads
Airport runways and taxiways
Port freight yards
Large parking lots

Product Introduction:

Quick-Change Milling Drum Assembly: Adopts a high-precision integrated design that connects the reducer and the milling drum through a transition roller, enabling the overall quick replacement of the milling drum in less than one hour. This significantly shortens the downtime for maintenance and notably improves construction continuity and overall efficiency.

Hydraulic One-Touch Rear Squeegee Control: The rear squeegee uses a hydraulic cylinder-driven one-touch open/close mechanism, completely replacing the traditional manual pin operation. It is more convenient and labor-saving to operate, while effectively preventing rear squeegee deformation caused by missing or dislodged pins, thus ensuring the flatness quality of the milled surface.

Fourth-Generation Optimized Base Helix: The milling rotor base adopts a fourth-generation optimized structural design, which significantly improves reliability and durability under heavy-load conditions—especially during high-hardness cement pavement milling operations. The discharge path is smoother, effectively reducing the risk of material blockage.

Powerful Engine Reserve: Equipped with a high-power, high-performance diesel engine with ample power reserve, it can easily handle hard pavement surfaces and complex working condition requirements, ensuring continuous and stable milling output. It also features excellent fuel economy, effectively reducing operating costs.

High-Efficiency Conveying System: Equipped with a conveying system driven by a large-displacement hydraulic motor, the heavy-load conveying capacity is improved by approximately 20% compared to the previous generation, and the material conveying efficiency is significantly enhanced. Especially when milling soft pavements, it effectively prevents work efficiency from being affected by waste material accumulation and blockage. The conveyor belt features a reverse function that can quickly clear jammed waste material, ensuring operational continuity.

High-Reliability Design: The discharge outlet is equipped with high-strength anti-collision grids that can effectively intercept the impact of large waste material blocks, protecting the core components of the conveying system. The fan adopts a double-row bearing independent sealing design for more stable operation and significantly extended service life.

Multi-Mode Steering System: Supports four modes: front-wheel steering, rear-wheel steering, crab steering, and coordinated turning. The newly optimized steering structure design ensures rapid steering response and precise, agile movements, giving the equipment excellent maneuverability even in narrow construction areas and complex terrain.

Intelligent Attitude Self-Adjustment Technology: Configured with an advanced body attitude self-adjustment system, it can sense and automatically compensate for body inclination in real time, always maintaining the machine body in a level position during milling operations. This ensures the consistency of milling depth and the stability of control, significantly reducing the labor intensity of the operator.
