Main features:
Strong adaptability of cross-section: Pioneering curved arm bracket structure, with large operating range, can meet the upper, middle and lower bench operation of two-bench cut method and three-bench cut method;
Strong adaptability of work method: curved arm structure, the boom can work below the level, which can realize the super-elevation arch excavation, overcoming the problem that traditional rock drilling trolley can't construct super-elevation arch;
Strong applicability for personnel: remote control operation, simple and easy to learn, close observation of the drilling situation, effective control of over-under-excavation; shorter length of the whole vehicle, mobile and flexible;
High efficiency and energy saving: the drilling speed of a single hole is 5-6 times faster than that of manual air drilling, which greatly improves the drilling efficiency.
