Abstract

See full text

A bolt centralizer for a bolting feed in a rock bolt system has a flexible body capable of elastically flexing from an upright posture for centralizing a rock bolt to a folded posture that permits a bolting feed to advance. The centralizer includes a passage for guiding the rock bolt into a hole drilled by the rock bolt system. The centralizer also includes a base for fastening the centralizer to a sliding carriage adapted to travel over rails of the bolting feed.
