It is an all-in-one pavement paving and concrete vibration tamping machine that performs vibration, slurry lifting, compaction and leveling in a single stroke. It features a plug-in vibrator and is available in 3-roller and 4-roll versions for improved finishing and compaction.
The machine is primarily designed for concrete pavement paving and leveling—roads, sidewalks, parking areas, small bridge decks and similar flatworks. For nonstandard uses (for example hot-mix asphalt), consult the seller to confirm suitability and any required modifications.
The plug-in vibrator is a detachable vibration unit that provides high-frequency compaction to densify concrete, reduce voids and improve surface finish. It can be engaged during construction to make the concrete more dense and improve bonding between layers.
The 4-roll version generally offers better leveling stability and more uniform compaction across the slab width, while the 3-roller version is lighter and more maneuverable. Both provide good results; choose based on project width, finish quality requirements and site access.
The machine uses common components and special bolts to connect units. You can easily adjust the arch/radian by loosening the connecting bolts and setting the frame to the desired curvature—typically adjustable about 5–10°. Follow the manufacturer instructions to lock settings securely.
Assembly is straightforward—units connect with standard components and special bolts supplied with the machine. Basic mechanical skills and common tools are sufficient. For first-time setup, follow the operator manual or request vendor assistance to ensure correct alignment and vibrator connection.
Power options vary by model and supplier (electric motor, hydraulic drive or small diesel engine are common). Check the specific model listing or contact the seller for available power configurations and requirements.
Regular maintenance includes daily cleaning of concrete residues, checking and tightening bolts, lubricating moving parts per the manual, inspecting vibrator components and rollers for wear, and replacing worn parts promptly to avoid damage.
Operators should wear appropriate PPE (gloves, safety boots, eye and hearing protection), ensure the machine is turned off and locked out before maintenance, keep hands and loose clothing away from moving parts, verify vibrator mounting is secure, and follow safe lifting and transport practices.
Common wear items include roller sleeves or bearings, vibrator elements (rubber mounts or eccentric weights), mounting bolts and seals. Keep a small inventory of fasteners and any model-specific components recommended by the supplier.
By combining vibration, slurry lifting, compaction and leveling in one pass, the machine reduces the number of operations and labor needed, produces a denser concrete layer and yields a more uniform flat finish compared with separate manual or multi-step methods.
Many models offer different working widths (and the choice between 3-roller or 4-roll) and can be used for typical slab depths encountered in road and sidewalk paving. For specific width/depth capabilities, request the detailed specifications from the supplier.
Transport requires a suitable truck or trailer and secure tie-downs; some units may need a forklift or crane for loading. Store the machine in a dry, sheltered location, clean concrete off after use and protect electrical/hydraulic components from moisture.
After-sales support, warranty terms and customization options (roller count, working width, power unit, vibration frequency) vary by seller. Contact the vendor for specific warranty details, spare parts availability, training and options to tailor the machine to your project needs.
