Description

The Fully Hydraulic Tunnel Drilling Rig

The fully hydraulic tunnel drilling rig is a highly efficient drilling device specially designed for mining tunnels and underground engineering. It can operate flexibly in confined spaces, making it suitable for exploration and construction in complex geological environments, and is widely used in various underground engineering projects.

Features of the Fully Hydraulic Tunnel Drilling Rig

  • The rig adopts a split structure, making it lightweight, easy to transport, and convenient for operation in narrow spaces.
  • The power unit uses an explosion-proof motor combined with an advanced hydraulic system to ensure safety and reliability.
  • The hydraulic chuck is designed to enable quick clamping and releasing of the drill rod, and features power-off protection.
  • The mast can slide and extend, closely aligning with the foundation to enhance operational stability and drilling accuracy.
  • It offers multi-angle drilling capability; the mast and swing arm can be flexibly adjusted to meet various drilling requirements.
  • The power head provides a wide speed range and strong torque, suitable for operations in different strata.

Application Fields

  1. Geological exploration of mines and tunnels.
  2. Construction of railway and highway tunnels.
  3. Underground projects for water conservancy and hydropower.
  4. Underground space development and engineering reinforcement.
  5. Gas extraction and safety hole drilling in coal mines.
