This volume, part of the specialized book series on conveyor technology and construction machinery, presents the fundamentals and rules for the dimensioning of machine components that hold equal importance for both conveyor and construction machinery. In addition to the extensive literature on classical machine elements, particular attention is given to those elements that have a distinct form, special characteristics, or significance in these machines. The engines are discussed in terms of the general principles of operation and design, followed by an explanation of the four main groups of conveyor drives. An introductory chapter preceding this material provides a systematic classification of the machines and conveys some fundamental concepts of operational durability. This comprehensive foundational textbook extends beyond theoretical study into the practical realm of engineering.
