Rescue Drilling
Large-Diameter Horizontal Rescue Drilling Rig
The large-diameter horizontal rescue drilling rig opens rescue and escape passages following construction collapses. The DJZ800-ND variant is configured for the transport-infrastructure sector and the ZYL-580/800S full-hydraulic variant is configured for the coal-mining sector.
Features
Wireless remote control keeps the operator clear of the collapse face; dual-wall casing protects rescuers and survivors.
Robust working stability with a comprehensive support package and a stuck-string release torque of 705 kN·m.
Dual diesel and electric power for fast on-site mobilisation; large-bore passage suits both rescuers and survivors.
Modular working assembly, undercarriage and spoil-removal systems for fast transport and assembly on site.
Manual and automatic drilling control modes, with automatic logging and on-screen display of working parameters for post-mission review.
