The new SD75B, SD115B and SD135B single-drum vibratory rollers from DOAN feature advanced technology that can handle a wide range of conditions and provide excellent construction flexibility and performance output, no matter how critical the construction environment is.
DOAN Construction Equipment Introduces a new single-drum vibratory roller that meets Stage IV / Tier 4 Final emission standards. These flexible, easy-to-use, smart and efficient rollers are designed to maximize operator productivity and productivity, regardless of operating requirements. For example, through a simple and easy-to-use console,Road Router Crack the operator can use DOAN's advanced vibration control system to adjust the vibration frequency and amplitude to suit different soil types and conditions. Equipment standard dual-frequency vibration system, can also be equipped with five-frequency vibration system, according to the construction and the depth of the impact of vibration requirements, can be high and low amplitude switching to adjust the vibration energy of steel wheel output. At the same time, the optimized excitation force output and automatic start-up function also enhance the compaction performance, compaction output and ease of operation.
The drive system provides excellent climbing and traction capability in difficult construction situations such as large-angle slopes or slippery surfaces to prevent skidding or idling of the rear or front wheels for superior climbing,Environmentally friendly asphalt paving equipment manufacturers market
The B-Series single-drum vibratory rollers are available in three different configurations, with either an optical or convex wheel. In addition, by adding a convex shell on the optical wheel, the conversion of the optical wheel and the convex wheel can be carried out quickly and easily on the roller, thereby further enhancing the flexibility of use of the new series of rollers.
High-quality DOAN engines that meet the Stage IV / Tier 4 Final emission standards feature high torque output at low speeds, reducing emissions without sacrificing power and reducing fuel consumption. SD75B, SD115B, and SD135B models come standard with ECO (fuel economy) mode, the engine speed can be matched with the operating mode, so that fuel consumption by up to 40%. In addition, the new design of the eccentric excitation mechanism can also lower the hydraulic pressure in a shorter time to start,Chinese Road Construction Equipment Parts and further reduce the fuel consumption of equipment.
The passive exhaust gas recirculation system automatically cleans the filter during normal operation, eliminating the need for additional operation by the operator and without reducing the performance output of the machine. The hydraulically driven stepless variable speed heat dissipation motor only works when required, Demand for engine power output. Low-speed cooling fans reduce operational noise, improve operational comfort, and help reduce long-term user costs.
Comfortable operation
The B-Series rollers also help to increase construction efficiency thanks to its industry-leading cab, which provides excellent visibility, ergonomic, centrally arranged controls and a comfortable interior Operating environment. The certified ROPS / FOPS cab is equipped with a full front window, which provides a clear view of the front wheels and an unobstructed view of the construction site. Multi-position adjustable seats can rotate and slide,most durable crack repair machine manufacturing to further enhance the operating field of vision and comfort. The new high-tech color operation display can display machine operating information and diagnostic information for critical faults. The information displayed on the display can be easily read even in the sunlight.
