STR12-5 fully hydraulic vibratory road roller
Features
The SR12-5 fully hydraulic vibratory roller is a heavy compaction machine mainly used for soil compaction in medium and large size projects, and it can be used for compacting non- or low-cohesive materials, such as gravel, crushed stone, sand/gravel mixtures, and concrete. It is the ideal compaction equipment for groundwork on highways, railways, dams, open pit mines, airports and other industrial sites.
The SR12-5 fully hydraulic vibratory roller has the following features:
1,Fully hydraulic, double drive, double gear continuous variable transmission;
2, Hydraulic motion, vibration and steering;
3,Double vibration amplitude, double frequency, and hydraulically articulated steering;
4,Centralized pressure measurement, and special technology useful for short distance towing;
5,Main parts such as the hydraulic pumps, motor, drive axles, vibration bearings, pipes and joints all use world-famous brands;
6,The cab is bright and spacious, and equipped with an air conditioner.
