12-Ton Single Drum Vibratory Roller – High-Efficiency Compaction Equipment for Road Construction

Overview

Core Features & Advantages

1. Superior Compaction Performance & Efficiency

• 12-Ton Operating Weight & High Compaction Force: With a total operating weight of 12 tons and a centrifugal force of 280–320 kN, it delivers deep compaction (up to 500mm for soil) and high surface density—ensuring the structural stability of roadbeds and building foundations.
• 1800mm Wide Vibrating Drum: The large-diameter (1500mm) single steel drum with a width of 1800mm covers a wide compaction area per pass, reducing the number of passes required by 20% compared to smaller rollers and accelerating construction timelines.
• Dual Vibration Frequencies: Equipped with a hydraulic vibratory system offering high (35 Hz) and low (28 Hz) vibration frequencies, adapting to different materials: high frequency for asphalt and granular soils (for smooth finishing), low frequency for cohesive soils (for deep compaction).
• Smooth Drum Surface: The polished, wear-resistant steel drum ensures no material adhesion and delivers a flat, uniform compaction surface—critical for subsequent asphalt paving or concrete pouring.

2. Maneuverable Chassis & Stable Operation

• Pneumatic Tire Rear Drive: The rear axle features heavy-duty pneumatic tires with deep treads, providing excellent traction on uneven terrain and loose soil. The tire-drum combination ensures the roller can climb slopes of up to 30% without slipping.
• Compact Maneuverability: With a minimum turning radius of 5.5 meters and a short wheelbase, it navigates narrow construction sites (e.g., urban alleyways, bridge approaches) and tight corners with ease—ideal for both large infrastructure and small-scale renovation projects.
• Hydraulic Steering System: Precision hydraulic steering with responsive controls ensures smooth, accurate positioning, reducing operator fatigue during long work shifts and improving compaction accuracy around obstacles.

3. Durability Engineered for Harsh Working Conditions

• Heat & Dust Resistant Design:
  • Engine compartment with a high-capacity cooling system (radiator + oil cooler) and a dust-proof air intake, operational at ambient temperatures up to 50°C—preventing overheating during continuous summer operation.
  • Sealed hydraulic components and electrical connectors with IP65 rating, protecting against dust, sand, and water ingress in dry or rainy construction environments.
• Wear-Resistant Components: The steel drum is treated with surface hardening (HB450+) to resist wear from gravel and sharp stones; the rear tires are made of heavy-duty rubber with cut-resistant properties for long service life.
• Corrosion-Resistant Coating: A multi-layer anti-rust system (zinc-rich primer + epoxy topcoat) covers the entire steel frame, protecting against corrosion in humid coastal areas or chemically contaminated industrial sites.

4. User-Friendly Operation & Enhanced Safety

• Ergonomic Operator Cab: Spacious, soundproof cab with air conditioning, an adjustable suspension seat, and a panoramic windshield for 360° visibility—reducing operator fatigue and improving job site safety. The control console is intuitively laid out with joysticks for vibration, steering, and travel.
• Intelligent Monitoring System: A digital display provides real-time data on vibration frequency, travel speed, fuel level, and engine temperature, with automatic fault diagnosis and alarm functions to prevent equipment damage.
• Comprehensive Safety Protections:
  • Emergency Stop System: Hardwired emergency stop buttons in the cab and on the machine body for instant shutdown in critical situations.
  • ROPS-Certified Cab: Reinforced rollover protection structure to safeguard the operator in case of accidental tipping on slopes.
  • Vibration Isolation: Hydraulic vibration isolation between the drum and chassis reduces cabin vibration by 40%, protecting the operator’s health during long hours of work.
  • Rear View Camera (Optional): Enhances visibility of the rear working area, preventing collisions with personnel or equipment on busy job sites.

5. Customizable Configurations for Project Flexibility

• Vibration System Upgrades: Optional variable amplitude (0.8–1.8mm) for precise compaction control across ultra-thin to thick material layers.
• Drum Customization: Choose between a smooth drum (standard for soil/asphalt) or a padfoot drum (for cohesive soil compaction, e.g., clay).
• Power System Options:
  • Diesel Engine: 110–130 HP 4-cylinder turbocharged diesel engine (Cummins/Deutz) compliant with EU Stage IIIA/IV emission standards, offering low fuel consumption (8–10 L/h) and high reliability.
  • Electric Motor: Optional 90kW electric motor for zero-emission operation in urban areas or indoor construction sites (e.g., underground parking lot compaction).
• Additional Accessories: Optional spray system for asphalt compaction (prevents material sticking), LED work lights for night shifts, and a ROPS/FOPS canopy for open-air operation in hot climates.
