Equipped with four independent hydraulic telescopic support legs, a 360 ° adjustable drilling arm, and a five-star hydraulic power head, operated by a single pilot, it can complete shallow anchor rod, locking foot anchor pipe, and dry surrounding rock advanced conduit drilling. The overall structure is simple and easy to maintain, suitable for municipal underpass tunnels, small dry mine tunnels, and frequently relocated construction sites in multiple sections. It supports basic waterproof modification for export to Southeast Asian dry tunnel projects and has a full set of export compliance qualifications.
