Categories: Grouting drilling rig, ZLJ series
This series of tunnel drills is mainly used for drilling operations at various angles in coal mines, including water exploration, gas exploration and release, dust prevention water injection holes, various engineering holes, and geological structures. The rig employs mechanical transmission and hydraulic feed, featuring a simple structure, compact size, and easy operation and maintenance.
This crawler drill is based on the original tunnel drill, equipped with tracks for autonomous movement, allowing easy walking and drilling even in narrow tunnels. The tracks are enhanced with four hydraulic columns on the original legs, providing better stability and higher safety. Additionally, a hydraulic holder is installed to enable automatic drill rod removal, making operation simpler and safer for workers, and drilling more efficient and labor-saving.
Increased power and stronger performance, capable of drilling in various geological layers such as coal seams, mixed coal-rock, and rock formations.
Mines: Suitable for water exploration, coal exploration, gas drainage, and dust-proof water injection at different angles in coal mines. Engineering: Suitable for grouting holes, wiring holes, pile integrity test holes, and core sampling holes in projects like subways, airports, highways, high-speed rail engineering, building reinforcement, and ground surveys.
