Overview

The KJ421 hydraulic tunneling drilling rig is qualified for the drilling of tunnels whose section falls in the range of 16-68 square meters. It is capable of drilling blast holes and rock bolting in a vertical, inclined and horizontal orientations.

Features

  • The drill rig is fitted with a flexible boom in two symmetric rectangular coordinates, without any operation blind spots. 360° rotation and self-leveling beam make drill positioning extremely easy. It can also be used for the drilling of lateral cross-cut and rock bolting.
  • The drilling rig provides a good view for the operator; balanced layout and the articulated chassis of four-wheel drive ensure the flexible, fast and safe driving in the narrow tunnel.
  • The stepped piston is used for the high-frequency impacting rock drill and this can improve the transmission efficiency of impact and drilling speed and reduce the consumption of drilling tools.
  • Considerable space and automatic functions enable the driver to concentrate on drilling in a safe, fast and accurate manner;
  • All the relevant parts are protected and maintenance is easy.
