Compact roller with new 4,000 vpm feature

Sakai’s 300 Series rollers consist of three small, double steel-drum rollers, and two combination, steel/pneumatic tire rollers, all of which deliver a high frequency of 4,000 vpm. This translates into higher operating speeds, while still maintaining the industry standard of 10 to 12 impacts per foot. The higher operating speeds and high frequency of the 300 Series allow contractors to get more compaction work completed before the asphalt cools and to achieve excellent compaction quickly. Machined drums and bevelled drum edges provide a smooth, well-compacted job.

The SW300-1, SW320-1 and SW330-1 double drum rollers have drum widths of 39, 47 and 51 inches, respectively, and are ideally suited for smaller scale jobs like municipal roads, driveways, parking lots, sports courts and bicycle paths.

Sakai’s TW320-1 and TW330-1 rollers combine both vibratory drum and pneumatic tires. These models feature 47- and 51-inch vibratory drums, respectively, on the front end for fast compaction, and pneumatic tires on the rear for surface finishing.

All five models feature a hydrostatic drive on both ends of the machine. These dual drive systems ensure that materials will always be pulled beneath the drums or tires to ensure compaction, while avoiding shoving and checking of the mix. Also standard on all five models is a fuel-efficient, 35-horsepower Kubota D1703-M-ET01 water-cooled diesel engine.

The 300 Series rollers have custom designed shock isolators which the company says are the strongest on the market today. This patented shock system reduces service and maintenance time on the roller by keeping vibration moving toward the material and away from critical components and the operator, reducing operator fatigue. In addition to the shock isolation system, the vibrator bearing is designed with an oil bath lubrication system that minimizes maintenance.
