KJ311 Full Hydraulic Tunneling Jumbo

KJ311 two-arm intelligent tunneling jumbo is a mainstream model for large-section working conditions. The 4WD articulated structure ensures excellent off-road performance and flexible relocation. Two 360° rotatable booms enable full-angle drilling with high efficiency on hard rock. The built-in intelligent system supports remote control, auto anti-jamming and fault diagnosis to improve underground safety. Complying with international mining standards, it has complete explosion-proof, dust-proof, noise reduction and exhaust purification configurations. The stable hydraulic system and modular design facilitate maintenance. It is core equipment for hard rock tunneling and support of overseas large mines, long tunnels and water hubs.

Product Description:

  • 360° full-range dual booms, no blind area for large sections

    Two independent booms rotate 360° and luff ±62°, drilling at any position on roadway roof, walls and face. No frequent relocation to improve efficiency.

  • 4WD articulated chassis, strong terrain adaptability

    4-wheel drive and articulated steering provide large traction and small turning radius. The 24° maximum gradient ensures stable travel on steep slopes, gravel and mud.

  • High-frequency high-power rock drill, efficient hard rock drilling

    17kW rock drill has high frequency and torque, drilling fast and neatly on granite and basalt, reducing rework.

  • Basic intelligent system, balance safety & efficiency

    Four functions including positioning, anti-jamming, diagnosis and remote control realize man-machine separation and reduce failure rate.

  • Multiple mining protections, reliable for high-risk conditions

    Mining Ex and IP65 grade, complete exhaust and noise reduction. It works stably in gas, dusty and humid underground for long-term use.

  • Heavy-duty hydraulic system, 24-hour continuous operation

    Large-flow circuit and multi protections resist fatigue and impact, keeping stable pressure under full load to guarantee project schedule.

  • Dual control modes, adapt to various scenarios

    Switch freely between local lever and wireless remote control, suitable for conventional and unmanned sites.

  • Reinforced body, anti-deformation & durable

    The thickened structure is optimized for vibration resistance, extending service life under long heavy load.

  • Modular layout, convenient overseas maintenance

    Power, hydraulic, electric and travel parts are zoned. Wearing parts are concentrated for easy on-site service.

  • Wide adaptation & high cost performance

    Suitable for mines, tunnels and water projects. Complete supply system makes it the first choice for large overseas projects.
