Description
The SMC-TE-D355C is a newly developed high-efficiency rock drilling rig designed for wide-ranging applications across mining, infrastructure, and excavation projects. Developed through extensive field research, this rig is built with a compact structure and engineered for reliability, versatility, and ease of use in demanding environments.
Equipped with a low-speed, high-torque hydraulic motor and an 18 MPa hydraulic system, the SMC-TE-D355C supports low, medium, and high-pressure impact hammers—making it adaptable to various geological conditions and drilling tasks. Its independent travel capability allows the rig to move without relying on an external air compressor, increasing flexibility and site mobility.
Known for its low energy consumption, simplified maintenance, and consistent performance, the SMC-TE-D355C is well-suited for use in mining, national defense construction, transportation infrastructure, and hydropower projects. Its efficient design significantly reduces compressed air usage during drilling, lowering operating costs and improving overall project efficiency.
The SMC-TE-D355C delivers a modern solution for rock excavation, combining proven functionality with the adaptability required by today’s drilling operations.
