2400rpm Full Hydraulic Soil Boring Machine Portable High Speed
MDT-2 Full Hydraulic Portable Drilling Rig Is A Kind Of Light Rig
Designed For Geological Exploration In Remote Area
MDT-2/MDT-2A Full Hydraulic Portable Drilling Rig
I．General Overview
MDT-2 Full Hydraulic Portable Drilling Rig is a kind of light rig
designed for geological exploration in remote area difficult to
enter. It is mainly suitable for diamond drilling with wire line
coring technique. The rig consists of diesel power unit, hydraulic
system, control panel, mast, main winch, wireline winch, drill
head, feed system, footclamp, etc. The rig is completely hydraulic
driven for all its surface coring function. Fission style design
makes the rig in good assemblability and disassemblability,
facilitating transportation to most inaccessible areas. Robust
structure plus exact control system ensures high penetration rate
and outstanding reliability.
Ⅱ. Main Technical Features:
1. Full Hydraulic and Drill Head model. The drill head rotation is
realized with four hydraulic pumps driven by two diesel engines;
this also makes the feeding hydraulic cylinder system realize its
full stroke feeding in both higher and lower speed.
2. With Good dismantlability. The rig is adopted split type in
design, including power unit, hydraulic oil tank, manipulation
platform and operation mechanism, i.e. the drilling section. So
they are in light weight and can be carried by man power or animal
power. The rig can be applied and performed in narrow space for
drilling of hole at 45°－90° with stronger adaptability.
3. Strong techniques adaptability. Besides diamond drilling with
wire line coring technique, it is in strong techniques
adaptability. It is applicable for the drilling and feeding
requirement of any other stratum.
