Coring Drill Rig Machine, MDT-350 Mechanical Hydraulic Mine Drilling Rig Coring Drill Rig Machine
 
1. MDT-350 drilling rig is a mechanical top-drive drilling equipment that integrates water drilling and gas drilling, which solves the difficulty of drilling air-drilling hammers in soil layers. The problem of low mud drilling construction efficiency, the dual-purpose water and gas drilling rig is suitable for various formations, and the core drilling efficiency and geological exploration are efficient and energy saving.


2. MDT-350 features of mechanical top drive water and gas drilling rig 
Equipped with hydraulic steel tracks for stronger off-road capability; 
Equipped with four hydraulic square tube high outriggers,which is convenient For leveling on site and saves a lot of loading and unloading costs; 
The left and right of the rig are equipped with drill rod holders and foot pedals, which are more user-friendly in design; 
The front end of the drilling rig is equipped with an auxiliary rod unloading cylinder, which makes it easier to loosen the drill rod; 
The hydraulic oil pump is directly connected to the power by a universal shaft, which makes the rig climbing and moving more powerful; 
The rig uses dual oil pumps to supply oil, and the hydraulic system uses split flow and merge technology to increase and decrease the power head more quickly; 
Equipped with a foldable auxiliary tower, which can lift two 3 m / drill drill rods at a time.
