DOAN has been focused on the development of high-end full hydraulic roller, after several decades of development and improvement, as the world's complete sets of road construction equipment, the most responsible leader in the field. DOAN tackles a number of technical problems to develop DOAN "pressure fast" series of the eighth generation of hydraulic single-drive single-steel roller, and will be subversive price return to our customers,chip spreader market will lead the low-end mechanical roller market changes.
DOAN roller in the construction machinery is a category of road equipment, widely used in high-grade highways, railways, airport runways, dams, stadiums and other large projects fill the compaction operation, you can sand, semi-sticky and sticky soil , Roadbed stable soil, gravel, gravel and other pavement layer. DOAN roller in the construction machinery is a category of road equipment,hot mix asphalt drum plant widely used in high-grade highways, railways, airport runways, dams, stadiums and other large projects fill the compaction operation, you can sand, semi-sticky and sticky soil , Roadbed stable soil, gravel, gravel and other pavement layer.
Dual-frequency dual-vibration mode, exciting force, pressure the same degree of density of the road, the efficiency of competition than the brand to enhance 16.7%. Before and after the change is simple and convenient, high construction efficiency. Compaction of the road surface formation, no impact, no starting indentation. The use of large displacement vibration motor,8m3 asphalt synchronous chip sealer starting time only 3 seconds. Vibration bearing invention patent: rat bag lubrication structure. The use of large displacement vibration pump and vibration motor, the system pressure is low, high reliability. Hydraulic transmission, transmission route is short, no impact. No need to replace the friction plate, low maintenance costs.
Three-stage brake: travel brake, parking brake, emergency brake, safe and stable. Around the operating position have the best working field of vision, after the visual field of 1m × 1m. Driving performance and through the good, full hydraulic drive, stepless speed. Before and after the conversion is simple and easy to operate, no step on the clutch, hanging file, brake, slow clutch and other actions. Comfortable operation - good damping effect, high-grade closed, three-level vibration of the cab,cold pour crack filler the working environment comfortable. Cab noise is less than 84dB (A), industry leading. Ergonomic design, comfortable and reliable. Maintenance and convenient, new industrial design, maintenance easier and more convenient. Main pump back, maintenance is extremely convenient. No friction plate, life-free maintenance.
