STR22MP Vibratory Road Roller
Features
The STR22MP padfoot vibratory roller can be used for compaction on clay and semi-clay, and it is ideal for highways, railways, dams, landfills and large backfill projects. By attaching or detaching the padfeet to the drums, the machine can be adapted for various working conditions.
The machine has the following features:
1, Mechanical drive, electrically controlled power shift transmission;
2, Hydraulic vibration and steering;
3, Double vibration amplitude, double frequency;
4, Unique gas pipeline control providing more convenient and flexible operation of the brake and clutch, increasing safety and reliability;
5, The gear shift and drive operations are controlled by a single lever, which is convenient, flexible and reliable.
