Main Components
  • Rotation unit
    Rotation unit
    The rotation unit delivers large torque and high reduction ratio which contribute to high transmission efficiency, stable operation and low failure rates. The reliable performance lowers maintenance costs.
    It reduces the possibility of drill bits getting stuck in unconsolidated formation and increases the success rate of drilling holes.
    High molecular liner plates are wear-resistant and durable, with no need of oiling.
    Manganese steel-framed guide rail is added to protect the mast from wear.
    Optional dual-drive high-low speed rotation system is available.
  • Automatic rod changer
    Automatic rod changer
    It is simple to operate the automatic rod changer to control rod storage, rod loading, unloading and movement of machine clamp just with one joystick.
    Adopting a clamping design, the changer can easily unload the rod and increase work efficiency.
  • Operation system
    Operation system
    All the operations of the rig can be realized by the integrated control system.
    The control system enables rapid feeding and lifting. The feeding force is adjustable based on different environments, which reduces drilling time and increases efficiency.
  • Undercarriage
    Undercarriage
    The undercarriage adopts a robust design of four wheels and one track. Widened tracks enable smooth travelling and strong climbing capability to support heavy-duty drilling jobs.
    4 leveling jacks are designed to angle to 10 degrees left and right to support drilling work in rough terrains. It supports high and low speed shifts to realize flexible movement between drilling sites.
  • Maintenance-fee feeding system
    Maintenance-fee feeding system
    Hydraulic-mechanical lock system supports stable torque output of hydraulic motors while avoiding hydraulic leak and sliding.
  • Dust collecting system
    Dust collecting system
    The hydraulic dust collector with a sliding cover that collects dust delivers stable and efficient performance, which extends the rig’s service life and ensures a clean working environment.
  • Power system
    Power system
    High-power turbocharged direct injection engine with water cooling function delivers reliable performance and is energy-saving.
    Two-stage air filter ensures intake of clean air and reduces failure rates of the engine.
    Imported hydraulic pumps feature pressure resistance, large output, high quality and long service life.
  • Air compressor
    Air compressor
    Atlas Copco air compressor with working pressure of 20 bar and air delivery of 18.5 m3/min demonstrates reliable performance to support drilling through a variety of rocks.

In terms of quarrying machines, rock drilling rigs include surface top hammer drilling rigs, rotary blasthole drill rigs, and surface DTH drill rigs which are the most important one.

Deep hole drilling rigs are applicable to drilling work in a variety of formations. Driving drill bits directly through drilling rods is more energy efficient, with less energy loss, and offers stable speed and high drilling precision. Deep-hole drilling rigs are also easy to maintain.
