| ROD HANDLING ARRANGEMENT |
Remote controlled hydraulic pilot rod handling arrangement directly to and from the rod rack |
| |
fitted on either side of the platform. Rod rack can hold total of 45 nos of 6 mt |
| |
drill pipes 4 1/2" OD which can be raised and lowered with Hydraulic cylinder. X-Y-Z axis |
| |
movement of the rod is done with hydraulic cylinder and motor control. The rod is carried from |
| |
either rack at one time and then moved into position under the rotary head for easy coupling |
| |
and
decoupling. Thus reducing burden on labour. |
