Rollers
Rollers are available in several categories: walk-behind and ride-on, which are available as smooth drum, padded drum and rubber-tired models; and are further divided into static and vibratory sub-categories.
Walk Behind A popular design for many years, smooth-drum machines are ideal for both soil and asphalt. Dual steel drums are mounted on a rigid frame and powered by gasoline or diesel engines. Steering is done by manually turning the machine handle. Frequency is around 4000 vpm and amplitudes range from .018 to .020. Vibration is provided by eccentric shafts placed in the drums or mounted on the frame.
Ride On Configured as static steel-wheel rollers, ride-ons are used primarily for asphalt surface sealing and finishing work in the larger (8 to 15 ton) range. Small ride-on units are used for patch jobs with thin lifts.
The trend is toward vibratory rollers. Tandem vibratory rollers are usually found with drum widths of 30” up to 110”, with the most common being 48”.
