LZ212A Two Booms Drilling Jumbo Rig

  • Operating range (W × H):16 x 12m
  • Drilling diameter:Φ41 - Φ102mm
  • LZ212A two booms drilling jumbo rig can meet the rock drilling operations such as system anchor bolts, locking foot anchor bolts, advanced small guide tubes, grouting holes, etc., and is suitable for various rock drilling operations in full-section excavation or step excavation of highways and railway tunnels with inverts. The maximum operating range of the equipment (W× H): 16m × 12m; the maximum drilling depth can reach 5.1m. It adopts local operation + wireless remote control, which can meet the full-section, two-step and three-step simultaneous excavation, solving the problem of "short" drill arm of traditional rock drilling equipment and the depth cannot meet the step distance.

    ◆ Wide range of applications: It can meet the needs of synchronous excavation of full sections and multi-steps, solve the problem of "short" drill arm of traditional rock drilling equipment and the inability to meet the step spacing in depth.It can meet the rock drilling operations such as drilling blasting holes, drilling anchor holes, drilling grouting holes and advanced geological drilling.


    ◆ Large working range: Maximum operating range (width × height): 16m × 12m, equipped with an expandable eagle-type boom seat, which can meet the needs of "large section" and adapt to the "small section" operating space.


    ◆Stable and efficient hydraulic control system: The whole machine adopts full hydraulic drive, three sets of independent rock drilling hydraulic systems, and the control does not interfere with each other. It is equipped with functions such as automatic drill jam prevention, automatic drilling and rod withdrawal at set depth, etc. The whole machine has reliable performance, accurate positioning, fast drilling speed and low drilling tool consumption.


    ◆ Convenient operation:  local operation + wireless remote control, can intelligently switch and control the movements of each boom.


    Safe and comfortable closed cab: The fully enclosed cab can be raised and lowered, with a wide field of vision, high safety factor, and effective reduction of noise and dust hazards. It is also equipped with air conditioning to ensure a constant cab temperature. 


    ◆ Electronic control technology: It has remote monitoring program, GPS positioning and MOTT data transmission and reception, drilling depth detection, water pump flow and pressure detection, electric anti-jamming and other functions.


    ◆ Intelligence (optional): Construction visualization, realizing APP real-time positioning, real-time monitoring, troubleshooting, simultaneous instruction interpretation, remote monitoring and many other cloud management functions.
