KJ211 full hydraulic tunneling jumbo is a cost-effective single-arm tunneling equipment. Adopting mature full hydraulic technology, it has compact body and flexible steering for narrow roadways. The multi-angle hydraulic boom and powerful rock drill ensure high drilling efficiency. The built-in anti-jamming structure reduces tool loss. Complying with mining explosion-proof standards, it is dust-proof and low-noise for humid & dusty underground conditions. Easy operation and low failure rate, it is a popular choice for overseas small mines, short tunnels, water projects and underground support drilling.
The minimum turning radius is ≤2.6m. It travels and turns easily in roadways above 2.0m, specially designed for small underground spaces.
All movements are driven by pure hydraulic power. The boom moves smoothly for accurate drilling and good hole quality.
The 15kW rock drill has strong impact force for medium-hard rock. The anti-jamming circuit releases pressure automatically to protect tools and reduce costs.
Compliant with underground explosion regulations. IP54 sealed body prevents dust and moisture. The multi-stage air filter protects the engine in dusty conditions.
The thick steel crawler has strong grip with maximum climbing angle of 22°, moving stably on steep slopes and gravel roads.
Integrated hydraulic levers with clear layout. No professional training required, saving labor cost.
Hydraulic, power and travel parts are arranged in modular zones. Wearing parts are easy to replace for overseas on-site service.
Optimized noise reduction design complies with underground occupational health standards.
Economical price and low failure rate. Universal spare parts make it the best choice for small mines and temporary projects
