SPT drilling machine

An SPT machine is a purpose-built drilling system that performs Standard Penetration Testing alongside conventional core drilling operations. It mounts a standardized SPT hammer assembly onto a full hydraulic core drill rig, so field crews can collect both soil strength data and rock core samples from the same borehole. The SPT drilling machine eliminates the

A core drilling machine for mining is a professional drilling equipment designed to extract intact core samples from underground for mineral exploration. It uses full hydraulic transmission to drive the drill pipe and drill bit, and can drill deep holes with high precision to obtain complete, pollution-free cylindrical core samples. This hydraulic core drilling rig
