New 20 ton Soil Compactor/ road roller Real price 2026.7.10 SEM 520 This machine in the picture is sold, we can order new machine for you (SEM 818F Bulldozer , New SEM 920F motor grader, SEM 922F , SEM 668F, SEM 655D wheel loader , SEM 822 , SEM 818F and other SEM series machines all receives orders ) Year 2026 SEM 520 is a 20-ton single-drum vibratory roller, designed and manufactured under Caterpillar's technology system. It combines advanced vibration performance with a durable powertrain, making it a reliable choice for medium to large-scale compaction projects such as highways, airport runways, industrial yards, and embankments . The core of its performance lies in the exclusive "Vibe Pod" (eccentric vibration pod) design licensed from Caterpillar. This system uses steel shots moving inside a sealed eccentric block to generate amplitude, which ensures a smooth start/stop, reduces impact shock on the motor, and extends system life by up to 50% . It features a 50mm thick drum, which is notably thicker than the standard 40mm found on many competitors, providing superior rigidity and 10%-15% better compaction performance . SEM 520 Key Specifications Parameter Value Operating Weight 20,000 kg (20 tons) Engine Power 129 kW (Weichai WP6, Tier II/Tier III) Drum Width 2,130 mm Drum Diameter 1,600 mm Static Linear Load 461 N/cm Vibration Frequency (H/L) 30 / 28 Hz Amplitude (H/L) 2.0 / 1.0 mm Centrifugal Force (H/L) 360 / 208 kN Travel Speed 2.98 / 5.88 / 9.60 km/h (3 forward/ reverse gears) Gradeability 34% Turning Radius (Outside) 6,350 mm Fuel Tank 262 L ⚙️ Key Features & Systems · Hydraulic System: It utilizes a closed-center hydraulic system, which is 20% more efficient than open-center systems. It uses world-renowned components (Sauer piston pump and motor) for reliability . · Cooling System: The isolated modular cooling system uses a suction fan to pull cool air through the radiator, allowing the machine to work effectively in ambient temperatures up to 43°C (or 50°C with optional high-ambient package) . · Powertrain: Equipped with an electronically controlled transmission for smoother shifting and less operator fatigue. The axle features a Proportional Torque Differential (PTD) which adjusts torque based on ground conditions, offering better traction (34% gradeability) . · Operator Interface: The dashboard includes a digital vibratory frequency meter to prevent over-compaction, and a Three-Level Alarm System that uses warning lights and audio alerts to notify the operator of system issues . · Maintenance: SEM offers a tilting cabin (hydraulic tilting is optional) that provides easier access to the pump, transmission, hoses, and electronic components for maintenance . This model is particularly valued for its Caterpillar-influenced vibration system and robust build quality, offering high compaction force and reliability for tough earthmoving and road construction projects.
