2400 mm Combined Surface Dressing Machine

2400 mm Combined Surface Dressing Machine

RTK - 2400CCS Combined Surface Dressing Machine is a state-of-the-art, vehicle-mounted solution designed for efficient road construction and maintenance. This versatile machine combines the essential components of bitumen spraying, aggregate spreading, and binder application in a single, streamlined system. It is optimized to handle the dual tasks of applying bituminous binder and distributing aggregate evenly across road surfaces, making it ideal for surface dressing projects aimed at enhancing road quality and durability.

The aggregate hopper in the RTK - 2400CCS has a capacity of 7 m³ to 9 m³, depending on the vehicle configuration, and is specifically designed to meet both country regulations and vehicle capacity requirements. This hopper ensures efficient loading, storage, and distribution of aggregates, which play a crucial role in the final road surface texture. Paired with the bitumen tank, which holds 9,000 to 11,000 liters of bituminous binder, the system is capable of handling large-scale road projects without the need for frequent refills. The bitumen tank is insulated with 50 mm rock wool and protected by a 1 mm aluminum plate, providing excellent thermal insulation to maintain the optimal temperature for bitumen application.

For ease of operation, the RTK - 2400CCS is equipped with advanced control systems that provide precise management of both bitumen and aggregate distribution. The 7" digital control panel located in the driver's cabin allows for full control over the bitumen spray and aggregate spread rates. Operators can easily adjust settings, ensuring that the correct amount of bitumen and aggregate is applied across the road surface. The 2.4" rear control panel adds flexibility, enabling the operator to make real-time adjustments from the rear of the machine. Both control panels feature PID (Proportional Integral Derivative) and proportional controls, ensuring smooth and consistent material application, regardless of the truck’s speed.

The machine is designed for single-operator operation, making it both efficient and cost-effective. The advanced hydraulic and digital control system ensures that the flow of bitumen remains consistent, regardless of changes in the vehicle’s speed. This is especially important in road construction, where even application is critical for durability and performance. An optional manual control system allows operators to take direct control of the bitumen application and aggregate spreading, providing additional flexibility where needed.

The RTK - 2400CCS features dual aggregate spreading hoppers, which can spread aggregate evenly across a width ranging from 300 mm to 2400 mm. These hoppers are equipped with easily adjustable manual lever controls, allowing the operator to regulate the amount of aggregate being spread with great precision. The adjustable hoppers enable an accurate application of material, preventing over-spreading or under-spreading, and optimizing the overall efficiency of the operation. The spreading range for the aggregate can be varied from 3 mm to 32 mm, providing flexibility depending on the road conditions and required surface texture.

The spray bar is another crucial component of the RTK - 2400CCS. The machine is equipped with three fully circulating opening spray bars, which are designed to provide an even distribution of bitumen across the road surface. The spray bars have a width adjustment range from 300 mm to 3000 mm, ensuring that the bitumen is sprayed uniformly across the entire surface. The spray bar movement is a combination of hydraulic and pneumatic systems, ensuring precise control over the spray width and distribution. The hydraulic system adjusts the spray bar for larger surfaces, while the pneumatic system fine-tunes the distribution for more precise applications, making the system adaptable to various road widths and project requirements.

The RTK - 2400CCS incorporates high-capacity diesel burners, which ensure the rapid and safe heating of the bitumen. These burners, with a capacity range of 190 kW to 310 kW, are connected to U-type flame tubes, allowing for efficient heating and consistent temperature control. For projects requiring even higher temperatures or better heat retention, an optional hot oil heated spray bar system is available, providing enhanced performance for challenging conditions.

Maintenance and operation are further simplified with the inclusion of a cleanable filter system designed for external suction. This system ensures that the bitumen pump and other components of the bitumen line continue to function smoothly, minimizing the risk of clogging or operational failures. The RTK - 2400CCS also features a single pump system that handles filling, circulation, spreading, emptying, and cleaning, streamlining the process and reducing downtime between operations. For areas that are difficult to reach, such as edges or tight corners, the hand bar spraying option provides additional flexibility, ensuring full coverage across the entire road surface.

The RTK - 2400CCS is engineered for long-lasting, efficient operation, with hydraulic equipment specifically selected to complement the system's requirements. The machine is powered by a vehicle PTO (Power Take-Off), providing reliable power for all components. Its hydrostatic bitumen pump has a capacity of 36 m³ (450 rpm), ensuring that the bitumen is pumped consistently and evenly. The open hydraulic circuit ensures smooth operation, even in demanding conditions, and the 50-liter hydraulic oil tank ensures the system has sufficient oil for prolonged use.

In terms of fuel efficiency, the RTK - 2400CCS is equipped with a 140-liter fuel tank and a 70-liter cleaning tank, ensuring adequate supply for both operation and maintenance tasks. The system’s pneumatic valve controls contribute to its reliability, allowing operators to make adjustments easily and effectively. Whether you’re working on a small section of road or a large highway project, the RTK - 2400CCS delivers precision and efficiency, making it an essential tool for modern road construction and maintenance.
