3.Hydraulic Steering & Mobility – Features hydraulic power steering (3000–4600mm turning radius) and 0–8/12km/h travel speed for agile site maneuvering.

4.Premium Component Integration – Equipped with Danfoss variable piston pump, NSK precision bearings, and Poclain hydraulic motor for robust reliability.

5.Customizable Operational Design – Includes electronically controlled water spray, LED work lights, and optional single-wheel vibration for diverse compaction needs.

The Application of Road Roller:

① Road Construction

Asphalt Pavement Compaction – Uses 60–70Hz vibration to ensure uniform density and smoothness for highways and urban roads.

Subgrade Soil Compaction – Stabilizes gravel, sand, and clay foundations with 45–55kN excitation force for long-term load-bearing.

② Municipal Projects

Sidewalk & Cycle Lane Building – Maneuvers in narrow spaces (3000–4600mm turning radius) for precise compaction of pedestrian paths.

Utility Trench Backfilling – Prevents ground settlement in pipe/cable trenches via adjustable hydraulic vibration.

③ Highway & Bridge Works

Bridge Deck Paving – Secures waterproofing and structural integrity for bridge surfaces with dual-wheel vibration.

Embankment Compaction – Reinforces layered earthworks on slopes to resist erosion and landslides.

④ Industrial & Port Areas

Warehouse Foundation Compaction – Supports heavy storage loads using 3500–3880kg operating weight and high static line load.

Port Terminal Paving – Withstands repeated heavy vehicle impacts via durable vibratory drums and robust frame design.

⑤ Rural & Low-Volume Roads

Rural Road Construction – Compacts unbound aggregates for cost-effective village road networks with 0–12km/h mobility.

Farm Drainage Ditch Reinforcement – Stabilizes earthen embankments to prevent collapse during seasonal water flow.
