KZ5 /KZ9 Surface DTH Drilling Rig
The surface DTH drilling rig is an advanced drilling solution that integrates the DTH drilling system with an automatic rod-handling system. The rig features a compact structure, strong integrity, and high mobility. It is equipped with a protective canopy and a rear-view monitoring system, improving operational safety and comfort during both drilling and relocation.
All movements, including traveling, feeding, rotating, dust collection, and angle adjustment, are hydraulically driven, providing strong climbing capability and stable performance. A hydraulic dry-type dust collection system effectively reduces environmental pollution.
The drilling rig delivers energy efficiency, environmental protection, high mobility, convenient operation, and stable performance. It is equipped with a hydraulic rod unloading mechanism for drill rod removal, along with a rod-handling device to reduce labor intensity. The rig is mainly used for rock drilling in quarrying projects and open-pit mining.
