Description

Full Hydraulic Crawler Rigs for Underground Coal Mines (Splitting Type)

Application

ZDY3200LF(A) and ZDY4000LF are splitting crawler mounted drill rigs with low rotary speed and high torque, mainly used to drill gas drainage boreholes with a wide range of possible angles in the roof and water detection/drainage boreholes. It is also used for other cluster borehole drilling operations in underground coal mines.


Features

There are three components of ad drill rig:drill unit, pump station and control panel. The control panel can be put on the drill unit during transportation. Three components can be flexibly set up according to the drilling site situation. Rigs have long feed stroke. A new rod can be easily added between rotator and holder to enhance the adaptability and to drill boreholes in a wide range of angles.
