Paver standard operating weight 18,000kg, hopper capacity 6.0m3, Paving Width Min/Basic/Extended/Max(m)- 2.05/2.55/5.1/8.8. The Dynapac SD Pavers combine decades of experience with constant innovation. During the development we have focused on the paving process and paving quality as well as increasing the reliability of the machines. The Dynapac SD range features the widest variety of choices: gas or electric heating, standard or high capacity work, 4 different power classes offering a sustainable drive concept, with Eco mode or an optional high performance system called VarioSpeed. All pavers come with the same service concept and operating system to ensure maximum uptime.
The Dynapac SD tracked pavers offer the safe impact system™ – a hydraulic anti-shock push roller that avoids the typical marks on the surface due to truck docking. The system also extends the docking length and gives you flexibility when working with different truck models.
Our Alpha-Track™ system is longer and wider to give you a smooth drive behavior and a perfect grip. The rubber track pads are 320mm wide which creates great ground contact. A high number of rollers inside the tracks improves the manoeuverability on curves. The tracks are also very low to give an optimal dumping height. These track pads are especially designed for paving application and have higher rubber thickness for longer life and lower cost.
Dynapac has designed the hopper with chamfered hopper edges to avoid cold asphalt sticking in the corners. A hydraulic front hopper flap reduces material spillage on the push rollers and on the road. It also helps to completely empty the hopper and reduces the amount of hand shovelling required. A very low dumping height makes collision with trucks almost impossible. The generous hopper leads to the widest conveyor tunnel on the market. The tunnel is shaped to create the best flow and to avoid any segregation of asphalt material. The twin conveyor system, 2 x 655 mm wide, with reversible drive, offers smooth material flow without segregation. We have a standard conveyor as well as a high capacity conveyor with double the number of conveyor bars for improved material flow. The auger compartment is fully visible from the operator’s position. The auger and auger tunnel are easily extended to fit wider working widths.
The Dynapac auger drive system is an improved centrally driven system with a slim gearbox (15cm) and small outer bearings that allow homogeneity of mixture, despite the high material throughput of up to 1100 tons per hour. The left and right auger drives have independent and reversible controls. This strong auger system has a torque to handle auger diameters from 380 mm up to 500 mm. In order to achieve optimized material flow for different paving thicknesses you can adjust the auger height hydraulically up to 250mm while paving.
All round visibility! The operator has a clear view into the hopper, conveyor and auger compartment, as well as on the marker bar plus he has direct eye contact with screed operators and truck drivers. The platform slides out up to 50 cm on both sides just by pressing a button on the dashboard.
Our ergonomically designed cabin makes sure that the operator can work comfortably and effectively at all stages of the the process. The platform offers generous head room and a flat floor with ample storage space. The big storage boxes in the floor of the platform improve the rear view. The roof offers 2 integrated working lights to the front and to the rear. The ergonomic seats, also available with seat-heating, can be adjusted to any position you need. Repositioning the dashboard has become even easier with the improved dashboard console. The Dynapac SD paver generation also offers a weather house with opening side and front windows for comfortable operation in all weather conditions. To improve the working environment and keep the fume level around the operator stand low, an optional fume suction system is available.
Atlas Copco’s TruckAssist system is designed to help trucks dock correctly and safely with the paver by simplifying communication between the paver and truck driver. The system comprises two sturdy, LED bars which are strategically positioned on both hopper edges. TruckAssist allows safe, efficient communication between the drivers of the paver and the truck, and enable the paver driver to remain in control of the truck docking process at all times. This feature is particularly useful in low noise areas, reducing the need to use the horn.
SetAssist system is especially useful where there is a large amount of spot work involved as it is designed to reduce setting and transport times on the jobsite. Now the paver driver has the option to save the position of the auger and screed before moving from one section to the next. One push of a button on the redesigned operator panel will then lift the hydraulic front flap, auger and screed, lock the screed for transport and reverse the conveyor slightly. Other features can be added by demand.
