KJ311 Integrated Secondary Breaker Two-Arm Tunneling Jumbo

KJ311 integrated secondary breaker tunneling jumbo is special all-in-one machine for underground drilling & breaking. Original independent hydraulic breaking arm realizes blast hole drilling, oversized rock crushing and ore pass unclogging on single unit, removing frequent equipment relocation and boosting tunneling cycle efficiency greatly. It fully retains mature configurations: 360° full-range dual booms, 4WD off-road articulated chassis, remote man-machine separation intelligent system and full mining explosion-proof protection. The breaker with built-in spray dust suppression generates no flying rock, eco-friendly for global hard rock mines, long traffic tunnels and underground water projects with large rock block disposal demands, being cost-effective dual-purpose export core model.

Dual-purpose integrated breaker for synchronous drilling & secondary crushing, eliminating separate breaking trolley procurement and cutting total equipment investment by 35%
Dual independent hydraulic supply main pumps with fully isolated drilling & breaking oil circuits, stable pressure without attenuation during simultaneous construction for soft & hard rock
Multi-degree-of-freedom swing & luffing breaking arm fully covers all blockage spots on roadway floor, side walls and ore pass openings with high clearing efficiency
Multi-stage stepless adjustable breaker impact force: light impact for soft rock to avoid over-crushing, full power heavy breaking for hard rock, adapting to mixed strata conditions
Built-in high-pressure water mist spray dust suppression nozzle on breaker head realizes synchronous dust removal during crushing, eliminating flying rock and dust hazards for safer eco-friendly underground work
360° full-range universal rotatable dual booms with ±62° wide luffing fully cover 10–32㎡ roadways without blind drilling area for outstanding tunneling efficiency
17kW high-frequency top hammer hard rock drifter with high shock wave transmission efficiency, fast drilling speed and low tool consumption on dense granite & basalt
4 independent driving wheel articulated chassis with 3m minimum turning radius and 24° max gradient for flexible relocation & obstacle crossing in narrow complex roadways
Dual operation modes: on-board console & long-distance wireless remote control, realizing man-machine separation during breaking & drilling to avoid blasting rock fall and gas safety risks
Full intelligent monitoring system: 3D roadway positioning, auto anti-jamming and real-time dual-system fault self-check to cut downtime loss
Official full-machine mining Ex explosion-proof certification with IP65 multi-layer sealing protection, compliant for mixed underground conditions with gas, heavy dust and humidity
Reinforced thickened integrated frame counteracts high-frequency reciprocating impact from breaker, resisting deformation & crack after long day-night cyclic drill-break construction
Modular quick-detach breaking arm for separate maintenance and wear chisel replacement, saving maintenance time & labor in remote overseas mining areas
Standardized universal design for all machine wearing parts, bulk global supply of breaking chisels & drilling tools with short procurement cycle and low maintenance cost
