Atlas Copco’s Superior Asphalt Solutions pave the way to surface quality

Atlas Copco Construction Technique’s powerful, rugged and efficient range of world-class paver and compaction equipment delivers superior asphalt solutions that are ideally suited for southern Africa’s tough working conditions.
Low operational costs as well as high quality paving and compaction results are fundamental to customers and end-users realising sustainable productivity, lowest overall cost of equipment ownership and ultimately profitability. Quality equipment that delivers powerful, reliable and efficient performance, is safe and operator friendly, requires little maintenance, has long service intervals and is easy to service are central to achieving these objectives. “The Dynapac range of asphalt pavers and rollers and Chicago Pneumatic compaction equipment deliver on all fronts,” says Neville Marthinussen, Atlas Copco Construction Technique Business Line Manager, Dynapac Road Construction Equipment. The newly launched Dynapac SD2500 PLC (Programmable Logic Control) large tracked and wheeled paver line which complements the well-known, proven F1700 and F2500 electric range is designed and engineered to take paving quality, which is measured in ride-ability, compaction, evenness and profile, to new heights. The SD2500’s host of features, including an intelligent logic control system and an efficient and powerful drive system, are focused on high performance screed, smooth material flow, efficiency, ergonomics and low maintenance and service. “In addition, the SD2500 features a unique safe impact system that absorbs the impact during truck docking and eliminates segregation of material on the asphalt mat, and further improves asphalt finish and therefore ride-ability and unwanted marks on the surface,” states Marthinussen. “The system which consists of a hydraulic anti-shock push roller also extends the docking length to give flexibility when working with different truck models,” he adds. When it comes to screed stability, Dynapac’s patented four-guiding tube principle delivers unmatched results. Marthinussen explains that as no supporting rods are required for the screed which reduce start-up paving time and increase available productive hours, particularly during limited available working time either due to inclement weather and/or access to road due to traffic requirements. All Dynapac screeds are free floating, ensuring excellent paving results. Another excellent feature of the SD2500 range which optimises work flow is PaveManager 2.0. This intelligent control system monitors the complete paving process and include pave parameters, pave memory function and automatic crown and slope settings. Marthinussen also points out that paving programmes can be conveniently set from outside the machine through the PLC. The SD2500’s optimised, longer hopper has a very low dump height for fast and easy material transfer from trucks and ensures improved paving quality. The machine’s slim gearbox and enlarged feeder tunnel allow homogeneity of mixture, despite the high material throughput of up to 1100 tons per hour. With operator comfort always a top priority, the SD2500’s new platform suits all needs from the operator’s perspective to ensure safe, comfortable operation. Excellent in-cab design features and low noise levels presents an ergonomic high-end workplace that gives the operator a full overview of the complete working situation at all times. Powered by a Cummins QSB6.7 diesel engine with emission stage IIIA or stage IIIB, the SD2500 machines require little and simple maintenance; the centrally located service points and components are direct, easy and rapidly accessible from the ground without any height adjustment required from the service technician, saving time and money. The maintenance process is further simplified by the large number of high quality plug-and-play components. When it comes to performance, application, compaction and operator control as well as maintenance and service, Dynapac’s tandem asphalt rollers are designed with across-the-board built-in quality and efficiency. The machine’s numerous operation features ensure high availably, extended life cycles, highest quality compaction through the HF system and surface finishes to maximise uptime and productivity. Soft starting and stopping prevents segregation, cracking or unevenness in asphalt layers; optimised ergonomics ensure continuous visibility and easy, comfortable controls for the operator while the rear mounted engine reduces noise and heat levels. The asphalt range is available in larger machines (CC2200 – CC6200) as well as smaller units CC800 – CC1300) which, with an operating weight of 1.3 to 4 tons, are ideal for smaller compaction applications in urban areas. The large drum widths of 1,500m to 2,130m (this is small roller drum width 800, 900 and 1000mm) make these units particularly effective on soft asphalt. The range is complemented by the CC900 and CC1200 units. The Chicago Pneumatic AR100 and AR120 ride-on rollers and MR7000 double drum rollers complete Atlas Copco’s asphalt offering. Powered by a water-cooled Kubota diesel engine and featuring respective drum widths of 39.4 and 47.2mm, the AR100 and AR120 rollers are a perfect combination of compact performance units. The fully hydraulic walk-behind MR7000 double drum roller also features a compact, robust design and a powerful engine so typical of the quality Chicago Pneumatic product range. This rugged unit operates reliably under arduous conditions, is easy to manoeuver in confined spaces and is suitable for compacting thin layers on granular soils and asphalt as well as applications where precision control is needed to handle small tolerances. Features include a world-class oil-cooling system to maximise uptime and stepless forward/backward control and an ergonomic handle for optimum operator comfort. Atlas Copco supports the complete paving and compaction equipment range with a complete after-sales service envelope that includes maintenance, repair, parts and spares. “Our skilled technicians are supported by our strategically located branch and distributor network,” concludes Marthinussen. /Ends Atlas Copco is a world-leading provider of sustainable productivity solutions.
