Wacker Neuson’s ride-on vibratory soil/asphalt rollers, the RD 12-90, RD 12A-90 and RD 16-90 offer a variety of enhancements to improve performance and operator comfort.
RD 12 Series
The RD 12 rollers offer a number of new features suggested by contractors. It starts with the elimination of overhang on the back of the machine. This was achieved by a redesigned frame and operator’s platform and the use of a pressurized water system. This new design provides added visibility for the operator and allows for the roller to get right to the edge of the asphalt for a complete and smooth finish.
The RD 12-90 features Wacker Neuson’s 20.5-hp WM 650 engine and the RD 12-90A comes with an 20.3-hp Honda engine. Both models weigh 2,490 lbs. (1,129 kg) and have a 35.4-in. (90 cm) wide drum width. These rollers offer 3,400 lbs. of centrifugal force in the front vibrating drum and the rear drum can be ballasted for additional weight if necessary. The RD 12 rollers offer hydrostatic drive with infinitely variable forward and reverse operation up to 5.4 mph (8.7 kmh), and even accelerations and stops for a smooth asphalt finish. These rollers also feature dual drum drive and articulated steering for accurate control.
Also contributing to the finish is a new pressurized water system, which allows for a more efficient and consistent water flow. The water pump timer is adjustable to eight positions, which allows the operator to better control the water flow, based on the asphalt conditions. Because this system is more efficient, the overall size of the water tank could be reduced, but the running time per tank of water has been increased, according to the manufacturer.
Improved operator comfort including significantly reduced whole body vibration and quieter operation are additional advantages to the RD 12 rollers. Contractors will appreciate the more spacious operator platform and sloped hood for enhanced visibility. The roller continues to feature the user-friendly control panel and right hand forward and reverse lever with integrated vibration control for easy operation.
The RD 12 series is ideally suited for compaction of level sub layers and finish layers on road repairs, driveways, parking lots and any asphalt surface.
RD 16-90 Roller
Also available in Wacker Neuson’s asphalt roller line is the larger RD 16-90. This 1.5 ton (1.3 t) diesel-powered unit offers the same new features as the RD 12 series including the overall redesign to eliminate overhang, increased compaction performance, pressurized water system and ergonomic enhancements.
The CE-compliant RD 16 also offers additional features to enhance performance and operator comfort. The centrifugal force of the RD 16 has been increased 30-percent over previous models and offers thicker drums for additional weight, plus dual drum vibration for outstanding overall performance and a quality asphalt finish.
The RD 16 also offers as standard a foldable rollover protection systems (ROPS) for easier transportation and storage, a rotating beacon light, working lights, horn and back up alarm. The ergonomic operator’s platform features a fully adjustable suspension operator’s seat for maximum comfort.
Wacker Neuson’s RD 16-90 is powered by a 22.5 hp Kohler diesel engine. The unit has an operating weight of 3,274 lbs. (1,485 kg) and with both the front and rear drums in the vibration mode, it can produce up to 6,800 lbs. of total centrifugal force. The RD 16-90 is designed for compacting base and finish layers of asphalt as well as granular material in confined areas. It is ideal for applications such as parking lots, driveways and shoulder work.
