BOLT RACK

550 483 12 BOLT RACK The primary function of this bolt is to firmly attach the guide track, or wear strips, to the main structure of the feed beam. The drifter cradle slides back and forth along this track during the drilling cycle. A secure connection is fundamental for ensuring the drifter travels in a straight line without any play or vibration.

When these bolts work loose or fail, the entire alignment of the feed system is compromised. A shifting track can cause the drifter cradle to bind or scrape, leading to accelerated wear on the slide components and the track itself. This misalignment also puts uneven stress on the drill string, which can reduce penetration rates and damage expensive consumables.

During routine inspections of the feed, check the tightness of all track bolts. Look for any signs of corrosion, thread damage, or wear on the bolt heads. A loose bolt should be re-torqued, but if the threads are damaged or the bolt is bent, it must be replaced to prevent more serious damage to the feed beam.
