Book Description

Excerpt from Machine Design: Hoists, Derricks, Cranes The author believes that no class of problems afford as good general training and practice as may be had in the design of cranes. The larger portion of crane details being the simplest machine elements are common to a wide field of machine design. The stresses both in the frames and machinery are readily determined by the elementary principles of mechanics and the design thus easily carried out on a theoretical rather than on an empirical basis. The book is intended to aid the work of machine design in technical schools and colleges and it is hoped it may prove useful in drawing-rooms where a general field of machine design is covered. The problems have been selected with this in view rather than that of appealing to the specialist in crane design. The engineering literature drawn upon includes the works of Bach, Bethmann and Ernst, and Machinery and Engineering Record among the periodicals. Through the kindness of several crane builders, catalogues, photographs, specifications and drawings, illustrating American practice, have been placed at our disposal.
