control panel is fully adjustable to either seating position.
Applications... esigned specifically for the rigorous demands of SUPERPAVE
D applications, the HYPAC C784 double drum vibratory roller is
designed to handle the largest and toughest paving projects.
With large diameter 54” drums, which minimize shoving of
material, and an 84” rolling width, this model has the capability for high
production results.
Maximum compaction output force is 41,235 lbs. per drum, with an
available 4,000 vpm operating frequency and rolling speeds of up to
4.54 mph. With this type of vibratory performance, required densities
can be achieved in fewer roller passes. Combine this with dual
waterspray systems per drum, exceptional operating visibility and
cutting edge control functions and features, the C784 HYPAC roller will
meet and exceed your every paving requirement.
