Trenton-Bleichert System of Aerial Tramways e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. This system of aerial tramways is one whereby the material is carried in receptacles suspended from carriages on stationary track cables of special construction, supported at varying elevations above the ground. The carriers move in a continuous circuit, at definite intervals, determined by the individual loads and the amount of material to be transported in a given time, and at distances apart varying in accordance with the speed; the loaded carriers traveling along a line of cable graduated in size to the weight it has to support, and the empties returning along a lighter line of cable parallel with the loaded line. Motion is imparted to the carriers by means of a comparatively light endless wire rope, of the ordinary or Lang lay, commonly known as the traction rope, to which the carriers are gripped. These Tramways belong to that class of aerial tramways known to many as the Double-rope, in contradistinction to the Single-rope class, wherein one rope performs both the functions of support and propulsion.<br><br>This system is especially adapted to the transportation of ores, coal, crushed stone, slate, clay, sand, and all kinds of raw materials. It is also well adapted to the conveyance of fruits, cereals and other plantation produce, cordwood and sawmill products, manufacturers' supplies, refuse, materials in process of manufacture, merchandise of all kinds, and particularly products requiring careful manipulation, such as explosives, liquids, glassware, and, in fact, all materials that admit of being carried in moderate loads.<br><br>The materials are carried in bee lines, directly from the loading stations to the places of delivery, without rehandling, at costs per mile varying from 2 cents to 5 cents per ton.<br><br>These Tramways are especially adapted to mountainous localities, and are recommended for heavy service. The ruggedness of contour, steepness of grades, and width of valleys or rivers, are
