Tunnel ZDY250 Diamond Bit Engineering Drilling Rig

The full hydraulic tunnel drill rig ZDY is a multi-function drill rig developed for drilling grouting holes in hydro-power stations. It can also be used for drilling support holes, penetration-proof holes, blasting holes, and treating dangerous rock and hillside.

This rig is primarily designed for drilling hard rock with diamond bits and PDC bits, as well as DTH drilling applications.

The Hydraulic Tunnel Drill Rig is widely used in:

• Tunnel anchor installation
• Tunnel drilling operations
• Vertical well drilling
• Pile hole (pipe roof) construction in roads, railways, and subways

• Drilling holes for water exploration and injection, gas exploration and discharging, geological exploration, and slope bolting
• All-direction positioning capability (±90°) for underground coal mines
• Split-type structure with main frame, pump station, and operational panel for easy disassembly and transportation
• Compatible with various drilling requirements using high-grade alloy, PDC drill bits, large diameter spiral drill rods, and core drill bits

• Hydraulic motor-driven feed and rotary head for lower air/oil consumption and reduced drilling costs
• High feeding force and rotary torque for complex worksites
• Explosion-proof design for tunnel operations
• Efficient hydraulic control system for horizontal movement
• Reliable components ensure high drilling efficiency
• Roller-equipped carriage minimizes drill guide wear
• Dual hydraulic clamps for easy rod loading/unloading
• Premium components including imported diesel engine and hydraulic parts
• Special compensation device protects drill rod threads
