BASE, BOOM

552 137 99 BASE, BOOM Serving as the primary structural arm, the boom assembly carries the full weight of the feed beam and drifter. It articulates to position the drill accurately against the rock face for collaring. The integrity of this main boom section is essential for absorbing the vibration and thrust generated during the drilling cycle, preventing stress from transferring to the rest of the rig.

A straight and structurally sound boom is critical for drilling accuracy and equipment safety. If the boom is bent or has excessive play in its joints, it becomes difficult to collar holes precisely, which can compromise the entire blast pattern. More importantly, any cracks or structural fatigue represent a serious failure risk that could lead to the boom collapsing.

Regularly inspect all weld seams for any signs of cracking, especially around the main pivot points and cylinder mounts. Any visible bending from rock falls should be assessed immediately. If the bores for the pins are worn oval, you will notice persistent looseness in the boom's movement that cannot be fixed just by replacing pins and bushings.
