Road roller or compactor is a type of engineering vehicle that commonly used to compact soil, gravel, concrete, asphalt or other materials in road construction, airport or port foundation work, at landfills or in agriculture.
Therefore, different types of road rollers are produced to meet the different project requirement. SANY provides you three types of road rollers including single drum roller, tandem roller, and pneumatic tyred roller. Fine production, years of research and development, rigorous tests ensure that each roller is defect free, even when working in the most complicated conditions.
Single drum rollers
SANY single drum roller is a vibratory type roller consisting of a large steel drum in front and two wheels in rear. The single drum rollers are available in a wide range of operating weight from 10 tons to 16 tons, with drum 1.5m to 1.7m in diameter and 2.13m to 2.17m in wide. The self-propelled vibratory drum delivers greater excitation force, increasing compaction efficiency and productivity in road construction.
SANY tandem roller consists of a large drum in front and a vibrating drum on the rear end, with operating weight varies from 3 tons to 13 tons. Two heavy drums surely increase the tandem rollers' weight, at the same time, the rear drum aids in compacting the road surface as the front drum passes over it. The tandem rollers adopt water wheel type lubrication on the vibratory bearing, and its plastic lined water tanks can provide water continuously to prevent asphalt from sticking to drums during the compaction.
Pneumatic tyred rollers
SANY pneumatic tyred roller or rubber tyred roller is made up of a heavy truck with rows of four closely spaced tires, widely used to compact asphalt road and cement stabilized base as well. The pneumatic tyred roller's maximum operating weight ranges from 20 tons to 30 tons, ground pressure adjustable from 200 kPa to 540 kPa, which greatly increase the evenness and smoothness of road surface.
