ROD HANDLING ARRANGEMENT |
Remote controlled hydraullic 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 |
