WACKER NEUSON RD 12-90A STATIC SMOOTH DRUM ROLLER

Technical Description

The Wacker Neuson RD 12-90A is a high-performance smooth drum roller designed for efficient compaction on asphalt and granular surfaces. It features a 35.4-inch (900 mm) drum width and a compact overall width of 3 feet, providing excellent maneuverability and visibility for precise operation. Powered by a reliable Honda GX630 air-cooled 2-cylinder gasoline engine delivering 20.2 hp (15.1 kW), the roller ensures robust performance with a maximum travel speed of 5 mph (8 km/h) and a maximum gradeability of 30%. The RD 12-90A incorporates dual drum hydrostatic drive and articulated steering for superior control and smooth operation. The drum vibrates at a frequency of approximately 3900 vpm (70 Hz), generating a centrifugal force of 3,400 lbf (15 kN) that enables uniform compaction and excellent asphalt finish. The machine has a substantial operating weight of about 2,963 lbs (1,344 kg), optimizing stability during compaction tasks. It also includes a 34.6-gallon (131 L) water tank to minimize dust and aid asphalt compaction and a 6.3-gallon (24 L) fuel tank for extended work periods. Other notable features include a pressurized water system with adjustable flow, optimized side clearance of 1.7 inches (43 mm), and curb clearance of 15.7 inches (400 mm), allowing close work near edges and curbs. Its dimensions (L x W x H) are 6.17 ft x 3.23 ft x 7.55 ft (1880 x 986 x 2300 mm), with a compact design enhancing ease of transport and operation on job sites requiring precise, high-quality compaction.
