CA 2699396

A foldable feed rail for a rock drill is composed of two segments, a first beam defining a first rail segment and a second beam defining a second rail segment. The second beam may be pivotally connected to the first beam with a hinge to enable the second beam to be folded relative to the first beam. Alternatively, the second beam can be detachably connected to the first beam so that the second beam can be removed altogether from the first beam. This invention enables the feed rail to be shortened, thereby making the feed rail much easier to manoeuvre in mines.
