（1） Features
Mechanical heavy duty single drum vibratory rollers effect powerful centrifuga force and great static linear load, are suitable for non-cohesive materials, such as sandy soil,gravel,crushed stones, rock fillings and slightly cohesive soils, designed for large foundation constructions such as high-class highways, mines, dams, airports, harbors, railways and industrial areas etc.
（1）Mechanical travel drive, double amplitude, hydraulic vibration and steering with optimal function/price ratio and reliable performance.
（2）Reliable WEICHAI diesel engine for convenient operation and maintenance.
（3）Two sets of brake devices, a hand brake and foot pedal brake, assure the machine's safety and dependability.
（4）Spacious and comfortable cab mounted on top quality rubber damping elements.
