The CYTJ45(G) mining hydraulic tunneling drill rig is a new product independently developed and manufactured by our company with independent intellectual property rights. It is mainly suitable for excavation and construction operations in various narrow roadways and tunnels in metal mines and other underground engineering projects. Its special drilling mechanism enables drilling operations in roadways of 2×2m to 2.8×2.8m, filling the gap in the market for small-section tunneling drill rigs. The drill rig adopts an electronically controlled hydraulic rock drilling system, which is advanced and equipped with an anti-jamming device, featuring fast drilling speed and high working efficiency. The entire machine has a compact structure, good maneuverability and mobility, and can significantly improve the working environment, enhance construction efficiency and construction quality.
