CONTROL CARD

550 596 38 CONTROL CARD This control unit is a key component of the rig's anti-jamming system. It constantly monitors drilling parameters and automatically adjusts feed pressure and rotation torque to prevent the drill string from getting stuck. By managing the hydraulic logic, it ensures the drifter operates efficiently without needing constant manual intervention from the operator.

Located within the main hydraulic control system, its proper function is essential for both productivity and equipment longevity. A faulty CONTROL CARD can lead to frequent drilling interruptions and, in severe cases, cause damage to the rotation unit or even snap the drill steel. It directly contributes to lower consumable costs and less mechanical stress on the entire feed and boom assembly.

Common signs of failure include the drill rig jamming more often than usual or a complete lack of response from the anti-jamming feature. Before replacement, check for any visible hydraulic leaks from its body or fittings. If the problem persists, the internal components are likely worn, and the complete unit should be replaced to restore proper automatic drilling control.
