Product advantage
The advantages of a tunnel anchor bolt jumbo (or cart) include:
Enhanced work safety: Tunnel anchor bolt jumbos are equipped with safety protection devices such as protective covers and safety doors, ensuring the safety of operators. The stability and precise control system of the jumbo reduce the risks associated with manual operations, minimizing the possibility of accidents.
Wide construction scope
The drilling arm can rotate 360°during propulsion, and the drilling arm with translational propulsion can drill holes in all directions, no dead angle;
High security
It has excellent power system, greatly improves the construction environment, and achieves green construction;
High work efficiency
The high-strength chain, combined with a high torque hydraulic motor, provides reliable pushing and pulling support during the drilling process; Accurate drilling reduces the occurrence of leakage and deviation during construction, significantly improving the blasting effect;
Operating platform
Ensure that the operator has a good field of vision, simple and convenient hydraulic control console, allowing the operator to operate easier and improve work efficiency;
