Safety Push Arm

The PEMAC Safety Push Arm enhances operation of the HawkJaw by means of a manually operated hydraulic control valve for powering the HawkJaw onto the tool joint and back to a convenient standby position. The control valve is mounted on, and moves with the HawkJaw. The arm is mounted well above the drill-floor, where it pushes or pulls the barrel of the HawkJaw’s lift cylinder to desired position.


The Push Arm improves operation efficiency and safety, as it:


1) overcomes the requirement to manually lower the HawkJaw to the drill floor for safe standby, which translates to time savings; and


2) reduces crew fatigue while labor is minimized to one-man operation, hence leading to higher safety as labour. Components are selected and arranged to withstand harsh environmental conditions, on top of minimizing requirements for routine maintenance, due to the elevated location of the equipment.
