Full Hydraulic Crawler Jet Grouting Anchor Drilling Machine (Max Depth:250M)
Jun 01, 2016

Application

ML-2 can be applied for carbide rotary drilling,auger drilling, all kinds of rotary spray(in a certain angle rotary spray, not rotating spray), with display unit for verticality of column. The rig can drill a series of holes with different heights and angles at the same position which can be applied on projects for deep excavation, anti-floating anchoring, foundation piles and geological disasters. Etc.

 

Features

1.With multi-directional change-range mechanism, convenient to drill a series of holes with different heights and angles at the same position;

2.High rotary torque, high drilling efficient;

3.With crawler chassis, easy and speedy to move;

4.The major components in hydraulic system adopt the imported brand and other components in hydraulic system adopt the domestic well-known brand. System is stable and reliable. They have a long service life;

5.Power head driven by hydraulic, can realize stepless speed regulation, with high speed and low speed;

6.Variable hydraulic system with load feedback, low energy consumption;

7.With display unit for rotating speed of top-drive head, lift speed and verticality of derrick, quickly and accurately to fix position;

8.Diesel-electric using dynamic range wider, reduce pollution, reduce customer construction cost.
