Hole Depth:3365 3975mm

Type:DTH Drilling,Hydraulic,Engine driven,Crawler

>> Introduction

 JCT45/2 hydraulic tunneling drilling rigis suitably qualified for the drilling of tunnekwhose section falls in the range of 45square meters,capable of drilling the blasthole and rock bolting in a vertical, inclinedand horizontal way.



The drilling rig is fitted with the flexible boom in two symmetric rectangular coordinates,without any operation blindspot360" rotation and self-leveling beam make drill positioning 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 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 wave and drilling speed and reduce consumption of drilling tools and make it in good condition;

>> Considerable space and automatic functions enable the driver to concentrate on drilling in a safe, fast and accurate manner All the relevant parts are kept in good protection, meanwhile maintenance easily.
