400m Deep Coring Drill Rig Machine, Geotechnical Diamond Core,
Hydraulic Rotary Water Drilling Rig Machine For Sale
1. MDT-400 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-400 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.
