Excerpt from The Underground Haulage of Coal by Wire Ropes: Including the System of Wire Rope Tramways as a Means of Transportation for Mining Products; A Practical Essay Written for John a Roebling's Sons Co; Of Trenton, N. J In the present little volume we offer to our patrons, mining engineers, and to all interested in the transportation of coal and other mining products, a collection of such useful, practical and theoretical information as will be of assistance in planning appropriate machinery for hauling and hoisting. We have refrained from filling the book with pictures and fancy sketches, and include only a series of carefully selected plans, representing the executed and approved conveying systems operated at the present day in the best American and English collieries. It was originally our intention to confine this treatise solely to underground haulage, but while preparing the same we received so many inquiries about wire rope tramways that we considered the subject but incompletely treated without describing this method of over ground transportation, which in many mining districts already plays an important part, and promises with every year to become more and more extended.
