Based on the study of rapid mechanized construction technology concerning soft surrounding rock and the characteristics of tunnel excavation by drilling and blasting, the new product of TKJ mechanized shotcrete manipulator is developed...
The main technical characteristics:
1.Better mobility
Articulated frame, small turning radius;
Cross-country tyre, good trafficability;
Strong climbing capacity;
No need of outriggers, pass in and out quickly;
2.Suitable for the construction by bench cut method (especially short bench method or mini -bench method)
Wet shotcrete machine and manipulator can be combined as a whole and also separated into two units, with strong adaptability.
3.Remote control system is taken in manipulator operation , to ensure l operator security and improve the work environment.
