Abstract
A barrel reclaimer has a drum member with axially extending series of openings provided with buckets for taking material from a stockpile. At least some of the series of openings terminate spaced from the end of the drum member and auxiliary tapered openings are arranged in line with each such series, between the end of the associated series and the drum end. The provision of auxiliary openings of the forms discussed is found to increase the fatigue resistance of the drum member. It is also helpful if the individual openings of each axial series are uniformly spaced from each other.
