Some Rules for Drawing up an Inquiry for Cranes

Abstract

Before a building is erected, the choice of a crane for a certain purpose, or of the complete crane equipment of the building is a comparatively easy matter. When the manufacturing process, the necessary machine tools with the space they require and the contemplated crane plant have been decided upon, the tables on page 89 contain all the data required to ascertain the section of the building, which should be adhered to, so that the crane has room to move freely in all directions and may be utilized to its full capacity. The tables also contain the maximum values for the crane bridge, which are necessary to dimension the girders of the crane track and their supports.
