WACKER NEUSON RD12A STATIC SMOOTH DRUM ROLLER

Technical Description

The 2016 Wacker Neuson RD12A Static Smooth Drum Roller is a compact, high-performance tandem vibratory roller designed for efficient compaction of asphalt, granular subbase materials, and soil. It features a robust operating weight of up to 2,964 lb with dual drum drive and articulated steering, ensuring precision maneuverability even in confined areas. The roller is equipped with a 35.4-inch wide and 22-inch diameter front vibrating drum and a static rear drum, delivering a dynamic centrifugal force of 3,400 lbf and an exciter frequency of 4,200 vibrations per minute for faster, thorough compaction. Linear forces applied statically are 31.4 lb/in front and 39.5 lb/in rear, with a dynamic linear force of 96 lb/in on the front drum. Powered by a reliable air-cooled, 2-cylinder Honda GX630 gasoline engine rated at 20.8 hp at 3,600 rpm, the RD12A balances power and fuel efficiency, consuming approximately 1.6 gallons of fuel per hour from its 6.3-gallon tank. Its pressurized water system, with an eight-position timer and a 35-gallon tank, ensures consistent water flow to prevent asphalt sticking during operation. The roller’s dimensions are approximately 74 x 38.8 x 90.6 inches (L x W x H), with a travel speed up to 5.4 mph forward and reverse and a max gradeability of 30%. It offers excellent curb clearance (15.7 inches) and side clearance (1.7 inches) for compaction near edges. The ergonomic operator station includes an integrated joystick controlling vibration and water functions for ease of use, making the RD12A suitable for asphalt paving, landscaping, and commercial roadwork requiring smooth, high-quality finishes.
