DL1 Long Hole Mining jumbo
DL1 Long Hole Mining jumbo

Product introduction:DL1 (CYTC76) is a compact and flexible electro-hydraulic mining drill rig for medium and deep hole operations in underground mine production. It adopts a compact design and is specially developed for medium and deep hole rock drilling in small tunnel mining. Flexible universal cantilever drill The arm can work in various deep hole arrangements such as vertical, inclined, parallel and fan-shaped.

Technical Features
  • Automatic Rod bank
  • Hydraulic drilling boom
  • Hydraulic Propeller beam
  • Chassis
  • control system
  • ● This boom is a horizontal rocker arm structure. It is a professional medium and deep hole rock drilling boom. It cannot be interchanged with the tunneling propelling boom to drill parallel holes.

  • ● The pallet-type drill boom is used for rock drilling with stable and accurate positioning rotated 360°.

    ● It can be used for medium and deep holes and also for tunneling. It can drill holes at any angle in the top, side and face of the rock.

  • ● Aluminum alloy heavy-duty propulsion beam, with character of high bending and torsion strength, and long service life.

    The surface of the propelling beam is covered with stainless steel, and the moving parts are made of PTFE wear-resistant liners.

  • Sturdy articulated heavy-duty chassis, diesel engine four-wheel drive, fast traveling speed and flexible transition characteristics, improve work efficiency; adopt power steering; chassis equipped with centralized lubrication system; the whole vehicle is equipped with four hydraulic outriggers for high stability when working.

  • It adopts a direct control rock drilling system with excellent automatic anti-block rod function. Its impact, rotation and propulsion use their own hydraulic pumps, and independent control loops ensure stable power output.
