Sany unveils hydraulic single-drum rollers

March 2017

Global heavy machinery manufacturer Sany has  launched the 20 tonne and 22 tonne hydraulic single drum rollers that give operators access to new technology and make work more efficient.

The new SSR200AC-8 and SSR220AC-8, both with 83.6-inch width, are equipped with Bosch Rexroth vibration pump, which feature large volume pump delivery and stable power transmission, shortening the starting time of oscillation to only 3 seconds. The new dual frequency and double amplitude vibratory mode is adopted to generate more excitation force and better compaction performance, the company said in a statement.

The WeiChai WP6G200E331 engine is deployed to provide 147 kW (197 hp) power, greatly improving the gradeability, and keeping the fixed speed even in the high altitude area. The Dynamic Systematic Thermal Conduction Control Technology ensures the roller to continuously operate in high temperature up to 46 degrees Celsius.

The wholly-enclosed operation cab features industry-leading anti-vibration technology, making the noise lower than 84dB, creating a more comfortable and focused working environment for the operator. Also, the 1m×1m rear view and optimised structure design gives superb visibility down to the drum, even when running, it said.

The new models in popular mid-range side and with perfect versatility can be employed in any compaction job. Whether for highway projects, dam construction, or for general site building, the new SSR200AC-8 and SSR220AC-8 can adapt to any road types, sandy, half-clayed and clayed soil, gravel and macadam, it added.
