The coupler is designed to extend the hollow anchor bar for use in a variety of situations that require varying lengths of hollow anchor rods. This ensures ease of operation in confined spaces.
During the drilling process, the coupler allows for direct end-to-end energy transmission between rods, minimizing hollow anchor rod loss, and ensuring maximum percussive energy on the drill bit. According to minimum load specifications, Sinorock couplers can guarantee that the ultimate breaking load is equal to the self-drilling rock bolt dimension
