1.Complete Basic Configuration Parameters

The 6212E is a high-performance 12-ton class double drum vibratory road roller for road construction. It has a standard operating weight of 12,500 kg and a drum width of 2130 mm, providing a large coverage area for efficient compaction. Equipped with a 119 kW high-stable power unit that meets international Stage III emission standards, the machine delivers continuous and reliable power output. It supports dual vibration frequencies of 45 Hz/50 Hz (optional 50 Hz/67 Hz high frequency) and dual amplitudes, with strong centrifugal force ranging from 85 kN to 140 kN. Adopting full hydrostatic three-speed walking system, it achieves a maximum travel speed of 12 km/h, with excellent gradeability and flexible turning performance to adapt to various complex working sites.

2. Superior Compaction Performance

This roller adopts a non-impact vibration excitation system with soft start and stop functions. It effectively avoids instantaneous impact on internal vibrating parts, greatly extending the service life of core components. Meanwhile, it prevents pavement bulging, cracking and uneven compaction problems, ensuring flat and solid compaction quality. The dual-frequency and dual-amplitude design perfectly matches different construction needs, realizing high-precision compaction for thick soil subgrade, stable base layer and thin asphalt surface, covering all working procedures of road bottom and surface layer construction.

3. Energy-saving & Efficient Working System
Built-in intelligent load sensing control system can automatically adjust power output according to actual working loads. It effectively reduces invalid energy consumption, achieving more than 8% fuel saving compared with traditional models and greatly lowering long-term operation costs. The unique 160mm crab walk offset design allows the machine to work closely along curbs, walls and bridge edges, completely eliminating compaction blind areas and improving overall construction integrity and efficiency.

4. Safe & Humanized Operation Design
Equipped with a ROPS-certified full-view panoramic cabin and shock-absorbing seat, the machine provides 360° unobstructed vision and comfortable driving experience, effectively reducing operator fatigue during long-hour continuous operation. The matched dual-circuit large-capacity water sprinkling system with triple filtration can uniformly cool and clean the steel drum to prevent material adhesion. Centralized maintenance and inspection points simplify daily upkeep, shorten downtime and improve construction continuity.

5. Reliable Qualification & Wide Application
The whole machine has passed CE, ISO9001 and international emission certification, fully complying with global export and construction standards. With stable full-hydraulic transmission performance, durable structure, low failure rate and convenient maintenance, it is an ideal core compaction equipment for highway, municipal engineering, airport runway and various earthwork and road foundation construction projects worldwide.
