Product Details
CYTJ45 Mine Hydraulic Tunneling Drilling Rig (commonly known as DD2): This is a brand-new, high-performance product specifically designed and developed for tunneling and rock-drilling operations in mines, water diversion projects, railways, highways, national defense, and other similar fields. It represents the company’s comprehensive upgrade and refinement of existing tunneling drilling rigs, based on site-specific operational conditions and leveraging our proprietary technological expertise. The machine features a highly reliable and safe all-wheel, four-wheel drive system with wet brakes; it employs fully hydraulic single-arm rock drilling and can be equipped with various high-power rock drills, achieving a drilling speed ranging from 0.8 to 2.5 meters per minute. It is suitable for a wide range of surrounding rock conditions. Powered by a China IV diesel engine, it boasts a four-wheel, four-drive, tire-mounted articulated chassis with excellent climbing capability—up to a 14° slope (25%)—and a maximum travel speed of 12 km/h.
