The Hypac C766C HO is a heavy-duty smooth drum roller designed for efficient compaction in asphalt paving, highway construction, and maintenance projects. It features dual 66-inch wide drums with a diameter of 48 inches, delivering a high vibration frequency range from 2,000 to 3,800 vibrations per minute, allowing for effective density and smoothness control on various asphalt mix designs. The machine is powered by a robust Cummins 4B 3.9-liter inline 4-cylinder diesel engine, providing reliable torque and power suited for continuous industrial use. Its full hydrostatic dual drum drive system ensures smooth speed and directional changes with low-speed, high-torque motors on each drum, facilitating high productivity and operator control. The roller's compact turning radius of 156 inches inside enhances maneuverability on site. Operator comfort and visibility are optimized through dual center-facing seats and a low-profile frame design. Additional features include radial pneumatic vibratory-drum isolators to reduce vibration transmission to the operator, a Multi-System Performance Indicator (MSPI) for automatic control of vibration start/stop and rolling speed, and an asphalt mat temperature sensing system to ensure optimal compaction conditions. The operational width is 81 inches, enabling the roller to cover substantial surface area per pass. Designed for maximum productivity in mainline paving, asphalt repairs, and resurfacing, the Hypac C766C HO combines rugged engine performance, advanced vibration technology, and ergonomic controls to deliver consistent compaction quality on diverse construction sites.
