Synopsis

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, hut 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 "overground" transportation, which in many mining districts already plays an important part, and promises with every year to become more and more extended.

The general plans, showing the disposition of the systems, are invariably sketched without scale, as it would have been impossible to illustrate, in a correctly proportioned drawing, all the different parts.

The details, however, are drawn to a scale, and in most cases the dimensions are added in figures, justifying us to trust that in combination with the explanatory text the subject may be clear even to the non-professional reader.

Of the numerous wire rope planes constructed in England and Scotland, we selected, according to our judgment, some of the best systems, and included such details as differ from those used in our country, and which may be of interest.

The majority of examples, however, are taken from the Monongahela c…
