Our Soil Investigation and Mineral Exploration machines come in different size for all types of capacity application. All GD series machines are mounted on crawlers, while GD150 and GD300 can also be mounted on skid for lower budget investment.
These machines come with high-speed Rotator while engaged by our HDM-design Geared Box Rotator Head. Since the gear-box motor is powered by hydraulic piston pump, it fully realeses enough torque even in high speed rotation. Together with Top-Flush Water Swivel and Hollow Spindle Shaft, one can easily adapt high-pressure water or air to ese the drilling works. Futhermore, the side-shifted Rotator Head works with the Wireline Winch, for SPT testing.
