CMM2-5 hydraulic bolting jumbo comes with compact design, making it suitable for bolting and drilling works on narrow drifts and tunnels. Due to the small footprint, the drilling equipment is allowed to work with other rock machinery at the same drifts or tunnels without affecting their operations. It is only Featuring a height of 2030 mm, this jumbo drills can easily travel through most mines.

Advantages at A Glance
  • Driven by a 45 kW explosion-proof motor, the hydraulic bolting jumbo adopts load-sensing hydraulic system integrated with Danfoss piston pump (130ml/r) and directional control valve.
  • Level/oil temperature protection provides long service life for drilling accessories.
