3.5 Tons Rear Rubber Roller
The 3.5 – ton rear rubber roller, certified by CE and ISO, is a versatile all – terrain compaction solution. Powered by a Changchai 390 diesel engine delivering 28.5kW at 2600rpm, it features a Dongfanghong gearbox with ≥92% transmission efficiency and a Danfoss hydraulic pump generating 55kN of vibration force for ≥96% gravel compaction. The 1200mm – wide rubber wheels ensure mark – free asphalt compaction, and the mechanical drive boosts complex – terrain passability by 50%. With a 6.5L fuel tank for 8 – hour continuous operation, its ergonomic design includes a yellow – black body, visual gauges, and a safety – compliant anti – slip pedal. Ideal for high – grade highways, ports, and post – disaster reconstruction, it offers reliable performance across various applications.
