STR22M Vibratory Road Roller
Features
The STR22M roller is a super-heavy vibratory roller that can carry out compacting work on different road and construction projects, through the use of its own weight and vibration force, providing reliable quality and high efficiency.
The STR22M can be used with various non-cohesive materials, such as gravel, crushed stone, sand/gravel mixtures, and concrete. It is the ideal compaction equipment for highways, mines, dams, airports, ports, industrial sites, and groundwork on construction projects.
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.
