Product Details

WTY-30A Light Drilling Machine

WTY-30A is designed for general prospecting, geologic structure prospecting, road and building construction prospecting, blasting hole drilling and other drilling projects

Specifications
Light, easy maintenance, less labor.
Rotary table can be stepped away from the drilling hole, facilitate the drilling task

Drilling rig and mud pump application range:

1): Projects: Construction drilling of the projects e.g. prospection, geotechnical investigation(geological exploring), railway, road, port, bridge, water conservancy and hydropower, tunnel, well, industrial and civil construction;

2): Exploration: Coal mining exploration, Ore exploration;

3): Water well: Small hole diameter water well drilling;

4): Foundation piling: Small-diameter hole foundation piling drilling

Feature:

1): adopted optimum technical preference, high mechanization, and low labour intensity

2): oil hydraulic driving equipped ensure easy handing and high efficiency

3): the revolving plate could be moved away from the hole with the front frame to ensure a wider working room. Multiple drilling modes selectable

4): optimized structure, small volume, lightweight, easy to remove and install, convenient for moving, assembling and repairing

5): transmission mechanism in drilling machine gear box makes rapid hole clean up possible

6): by adopting external dry clutch, the gearbox becomes more compact, ensures easier operating and maintenance

7): in its rotary table, the newly installed bevel gear makes it running more smoothly, more adequate lubricate and long working life, direct connection with gearbox, more compact structure. Adopted lighter 40 cylinder, improved chuck ball system, new lever locating set, helps a reliable easy operating, the gross weight of the whole revolving plate has been reduced to half of original

8): New gear on high RPM(578r/min), in case of drilling hard rock, user could use 76 diamond to drill

9): the cantilever support of lifter planet gear has been changed to double support to raise the lifting capacity and working life

10): enhanced frame steel spec to enforce the entire rigidity and intensity of frame
