Product Overview
The Brand New SEM 520F is a high-efficiency 20.0-ton single-drum hydraulic vibratory soil compactor engineered for subgrade, highway, railway embankment, airport runway, and industrial site compaction. Powered by a high-torque 129 kW engine @ 2,000 rpm, the SEM 520 features Caterpillar-technology eccentric vibration pod design and a heavy-duty 50 mm thick drum, delivering 10%–15% higher compaction efficiency. Outfitted with a Proportional Torque Differential (PTD) axle, closed-center hydraulic system with world-renowned plunger pumps/motors, Cat® Product Link™ telematics, and a tiltable cab, this roller delivers superior traction, low operating costs, and high durability.
Key Product Features
High-Efficiency 50 mm Thick Drum: Heavy-duty 50 mm thick vibratory drum shell paired with Caterpillar eccentric vibration pod design delivers maximum dynamic impact force and superior surface density.
Extended Vibration System Lifespan: Enclosed eccentric pod mechanism with moving steel balls minimizes motor shock loads, prevents hydraulic contamination, and extends vibration system lifespan by over 50%.
PTD Axle & High Gradeability: Proportional Torque Differential (PTD) axle dynamically distributes wheel torque based on ground conditions, boosting traction and providing 34% gradeability.
Isolated Modular Cooling System: Suction-type cooling fan pulls cool air through the radiator for reliable operation in up to 43°C ambient conditions.
Tiltable Cab & Cat® Product Link™: Features a tiltable cab design for fast engine/hydraulic serviceability, digital vibration frequency monitoring, 3-level alarm alerts, and Cat® Product Link™ fleet tracking.

FAQ
Road rollers are heavy and high-density mechanical equipment. Depending on their tonnage and dimensions, we offer the following shipping solutions:
Container Shipping (40HQ / Flat Rack Container): Small and some medium-sized road rollers can be loaded into high-cube containers; large-tonnage single-drum road rollers can be shipped using flat rack containers.
Ro-Ro Ship: The equipment is loaded onto and unloaded from the ship as a whole and transported entirely within the hold, providing protection against moisture and rust and ensuring the highest level of safety.
Breakbulk Ship: Suitable for shipping road rollers in bulk or for super-heavy compaction equipment.
We can recommend the best model based on your specific project requirements:
Subgrade/Earthwork Compaction (sand, gravel, clay, etc.): We recommend single-drum vibratory rollers (such as our top-selling models: 12 metric tons, 14 metric tons, 20 metric tons, 22 metric tons, etc.); if the material contains a large amount of clay or boulders, you can install a studded drum or (Padfoot Shell Kit).
Asphalt Pavement Paving and Repair: We recommend using a double-drum roller (equipped with front and rear water tanks for spraying) or combining it with a rubber-tired roller for final compaction.
Yes, we guarantee that all construction machinery we sell is 100% brand-new. Each unit undergoes rigorous factory testing before shipment and comes with the original factory certificate of conformity, warranty, and technical documentation.
We specialize in supplying brand-new road rollers from well-known brands such as XCMG (Xugong), SANY (Sany), SDLG (Lingong), SEM (Shangong Machinery), and SHANTUI (Shantui).
