Full Technical Description

550 433 82 CONTROL ARM As a key part of the boom or feed positioning system, this CONTROL ARM acts as a rigid lever. It connects a hydraulic cylinder to the main structure, converting linear push and pull into the rotational movement needed to articulate the boom. Its correct geometry is essential for the rig's ability to reach the designed drilling pattern accurately.

Wear or damage to this arm directly impacts drilling precision and operator safety. For example, if the pivot points become worn, the entire feed beam can develop excessive play, making it difficult to collar a hole correctly. A bent or cracked arm can fail under load, leading to a sudden, uncontrolled movement of the boom.

Look for signs of fatigue, like cracks near the welds or pivot bores, during routine inspections. Any noticeable looseness or 'slop' in the boom's movement when changing direction can indicate worn-out bushings within the arm. Replacing a damaged CONTROL ARM promptly prevents further wear on connected pins and cylinders.
