· 's new, high-production B-Series Tandem Vibratory Rollers include the 12- to 14-metric-ton CB64B, CB66B and CB68B models.. The rollers are well suited to all types of mix designs and applications. They provide high variation of amplitudes for breakdown and intermediate work, while their high static linear loads deliver excellent results for finishing work.
· To improve the ride comfort of the off-road vibratory roller, the cab's hydraulic mounts were analyzed to prevent vibration sources transmitting to the cab. However, the cab's low-frequency shaking in the vertical direction and the direction of forward motion is still great. This study proposes an optimal fuzzy-PID control method for semi-active cab’s hydraulic mounts based on an ...
This paper presents experimental study on corrugation phenomenon growing on the top surface of rail in a tight curve of track. One of the characteristics of the corrugation is to involve a slight ...
· 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".
· Featured Rollers. The focus is on three models: the 2.8 tonne and 1.6 tonne powered ride-on dual vibratory rollers and a 500kg pedestrian single drum reversible roller. Ride-Ons. Both ride-on models are powered by popular diesel engines. Turn the …
· The Three Musketeers Ride Again. ... pneumatic tired or vibratory rollers or a combination of those three. How you achieve compaction depends on a combination of different variables.Some of these variables include mix design, temperature of the mix, speed of the paver, vibration from the screed, roller types being used, weight andwidth of the ...
· To improve the soil compactor ride comfort, a combined control method of Fuzzy and PID control is proposed to control the cab isolation system of soil compactor based on the non-linear vehicle dynamic model. The vibration excitation sources are concerned by the vibrator drum and elastoplastic soil (EPS) interactions in the compression process.
A 3D air spring model with friction and orifice damping [5] studied for the train projects was then applied for the cab's isolation system of the vibratory roller to increase the ride comfort [6 ...

To have an overview of the research and development processes of the cab isolation system of the off-road vibratory rollers, this paper represents the researches of the various isolation systems based on the previously studied and published results. The result has shown that …
· Inc. has new high-production B-Series Tandem Vibratory Rollers that include the CB64B, CB66B and CB68B models.These machines are 12- to 14-metric-ton compactors that feature wider drum widths, high-flow water spray system, increased …
· Multiquip's AR-13 tandem drum ride-on rollers are now available in both diesel- and gasoline-powered models. The 3,142-pound (1,414 kilograms) AR-13D diesel-fueled model is built for asphalt and compaction jobs making it ideal for work on parking lots, driveways, road repair and patchwork. The AR-13D roller boasts an impressive 3,100 pounds ...
For vibratory rollers, the static weight of the machine plus the force generated by its eccentric motor creates centrifugal force, which helps determine the achievable compaction depth. Too heavy of a machine used on a thinner lift can cause over-compaction, and too light of a machine …
· August 28, 2006. Sakai's CR270 is a 35.4-inch-wide compact vibratory asphalt roller which was modelled after their field-proven larger asphalt versions. It has the same high frequency of 4,000 vpm as Sakai's larger machines. A combination of rear-drum static forces and internal front-drum vibration with centrifugal forces up to 2,975 pounds ...
· The CB44B and CD44B tandem vibratory rollers compete in the 7 to 10 metric-ton (7.7 to 11 U.S.-ton) size class, while the CB54B and CD54B compete in the 8 to 11.3 metric-ton (8.8 to 12.5 U.S.-ton) class. The engines are Tier 4 Interim. The rollers are well suited to all types of mix designs and applications.
Vibratory compacting roller machine and operator control therefor A vibratory ride-on roller machine includes a chassis supported on front and rear vibrating drum assemblies that compact the surface on which the machine travels. The machine is controlled via a...
In order to improve the vibratory roller's ride comfort, a 3-D nonlinear dynamic model of the vehicle interacting with the off-road terrain is established. A damper hydraulic mount is studied and combined with the cab's rubber mounts to simulate and evaluate the performance of the ride comfort. The weighted RMS acceleration responses of the vertical driver's seat, the cab's pitch and ...
A hydraulic damper is developed to generate the shock wave in this paper. The working principle of the damper is explained and the corresponding mathematical model is established.
This study proposes a dynamic model of the vibratory roller interacting with the off-road deformed terrain to analyze the low-frequency performance of three different cab's isolation mounts under the different operating conditions. In order to evaluate the ride comfort of the vibratory roller with the different cab's isolation mounts, a three-dimensional nonlinear dynamic model is established.
In the study of vibration of the vibratory roller, the effect of the rough terrain surface to the vehicle's ride comfort response was also almost concerned based on the point contact of the tires ...
