BREAK OUT WRENCH
To open the drill joints hydraulic break out wrench of 350 mm stroke will be provided
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
