II. Major Components

.1 Control Table

Feeding, rotation, reversing, rod lifting, clamp jaw tightening and releasing,winch winding and releasing all controlled through the handles on the control table.

Simple in operation but powerful in control.

2 Power Unit

The power unit is mounted on a wheeled frame independent to the drill body. It is composed of electric motors, hydraulic pumps, hydraulic cylinder, hydraulic oil tank, and electric control box.

6 Hydraulic Rod Holder

The clamping action of the clamp jaws in the hydraulic rod holder is synchronized with the hydraulic chuck in the power head. The tightening of the clamp jaws is mechanically operated, while the releasing of the clamp jaws are hydraulic controlled. This ensures that when there is un-expected stoppage in the drilling operation, the drill rod can still be strongly held by the rod holder, so as to ensure the safety in the drilling operation.
