HYPAC C766D STATIC SMOOTH DRUM ROLLER

The HYPAC C766D is a tandem smooth drum vibratory roller designed for high-efficiency asphalt compaction in highway, mainline paving, and resurfacing applications. It features a 66-inch wide by 48-inch diameter smooth steel drum on both front and rear, providing a static linear load of 182 lb/in for consistent, high-density compaction. The roller delivers a variable vibration frequency range of 3,400 to 4,000 vibrations per minute (vpm), with selectable high and low frequencies (67 Hz and 57 Hz) and a medium nominal amplitude of 0.1 in, enabling optimized performance across a variety of asphalt mixes and job conditions. Power is supplied by a Cummins QSB4.5 four-cylinder diesel engine rated at 130 hp (97 kW) at 2,200 rpm, ensuring reliable performance and quick response. The C766D has an operating weight of 24,000 lb, a maximum travel speed of 10.1 mph (16 km/h), and a tight inside turning radius of 13.6 ft for excellent maneuverability on job sites. Key operating capacities include a 50-gallon fuel tank, 4.8-gallon cooling system, and 4.3-gallon engine oil capacity, all supported by a 12-volt electrical system. With a ground clearance of 15 in, overall length of 16.7 ft, and cab height of 9.3 ft, the C766D combines compact dimensions with robust compaction performance for demanding paving operations.
