Description
Product Overview
Used Road Roller
The road roller, also known as the earth press, is a kind of road repair equipment, divided into steel wheel type and tire type two categories. Road rollers belong to the category of road equipment in construction machinery, and are widely used in filling compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, DAMS, stadiums, etc. They can roll sand, semi-viscous and viscous soil, subgrade stable soil and asphalt concrete pavement layer. The roller is suitable for various compaction operations by the gravity of the machine itself, so that the rolled layer has permanent deformation and compactness.
FEATURES AT A GLANCE
Key Features
Road rollers use vibration(eccentric shafts)for 95%+ compaction efficiency,adjusting amplitude(0.5–2.5mm)for materials like soil or asphalt.Hydraulic systems enable smooth speed control(0–12 km/h)and fuel savings(15–20% efficiency).They adapt to surfaces:steel drums for heavy base layers, pneumatic tires for asphalt uniformity.Safetyincludes ROPS/FOPS-certified cabs,automatic braking,and slope stability(30% gradeability).
Environmentally, Tier 4 Final engines cut NOx emissions by 90%.Compact models(1.2m width)excel in tight spaces like urban alleys.
