Dynapac articulated compact tandem rollers are designed for asphalt compaction in tight spaces, such as streets and pavements in urban areas.
The CC1100, CC1200 and CC1300 models are available in either a dual steel vibratory drum configuration or in a combi version featuring one vibratory drum and four rubber rear tires. The machines are powered by water-cooled Kubota diesel engines, which are designed to run quietly and fuel efficiently.
The CC1100 weighs 5,070 lbs. (2,300 kg) and features a 42-in. (107 cm) drum width; the CC1200 weighs 5,360 lbs. (2,431 kg) and has a 47-in. (119 cm) drum; and the larger CC1300 weighs 8,270 lbs. (3,751 kg) and features a 51 in. (129 cm) wide drum. The CC1300 is considered suitable for compacting sub-bases and base courses and can follow a small paver, according to the manufacturer.
The CC1100 and CC1200 feature drum diameters of 27 in. (68.5 cm), while the CC1300 has a 32-in. (81 cm) drum diameter, making these models especially effective on soft asphalt compounds. In addition, the ratio of drum diameter to static linear load will help reduce the risk of surface cracks. The high clearance at the drum edge is designed to facilitate compaction close to high curbs.
With the combi versions of the three models, the rubber tires are operated in pairs by separate drive motors. This can reduce the risk of marring newly laid asphalt when making turns, according to the manufacturer.
The Dynapac articulated compact tandem rollers are built using common parts to ensure better parts availability and to help retain resale values.
