Product Introduction

Main features:

① Designed for tunneling working faces with a height of 3.5~4.8 meters;

② The walking part of the unit has manual and remote control functions, with a remote control distance of 50 meters;

③ It is equipped with two sets of drilling arms and drilling hole propulsion mechanisms, which have manual operation, remote control and automatic control functions, and the two sets of drilling arms and drilling hole propulsion mechanisms can operate independently and simultaneously, and can achieve 360° all-round construction of top plates, side anchors, anchor cables, head-on blast holes and detection holes;

④ It is equipped with a liftable working platform, and the two sets of drilling arms can be raised and lowered with the working platform to meet the construction requirements of different tunnel heights;

⑤ The airborne drilling rig adopts valve group modular control and integrated oil circuit system, which makes the drilling rig compact, flexible in propulsion, easy to install and safer;

⑥ Wireless remote control technology is used to start and stop each motor, and each explosion-proof solenoid valve is driven to wirelessly control each action of the drilling vehicle, making the whole machine safer and more efficient;

⑦ Equipped with a 60-meter automatic cable winding device.
