Show the use of the bleichert Blei cherf aerial tramway in utah the use of the aerial tramway has long been recognized as a most ideal way of transporting materials and especially in minin mining communities has its utility become gene general fal for the economical carrying of ores from mine to mill or railroad centers he tram is almost indispensable and this method has many advantages over the wagon haul and other means of transportation there are several important tramways tram ways tion lion which the manufacturers claim easily make it the best on the market the first difference pointed out is the patent locked coil track cable the cable is so constructed that each strand is firmly locked to its fellow allowing no play and adding greatly to the strength and rigidity of the rope the outer strands are flat giving a smooth surface and the appearance of a solid steel bar the second typical feature of the v e R h vo oo 00 A jr 4 al 1 in utah but we shall mention only those of the bleichert type constructed by the trenton iron company of trenton N J for whom jones jacobs the well known salt lake engineers and contractors are the local representatives the bleichert system of wire rope tram ways is the production of a german inventor of that name who is now building them in europe and where they find more gener general ill use than any other make of tram the fundamental da mental idea that of carrying loaded buckets on wire cables is essentially the same in all makes the bleichert elchert Bl however has minor details in construction and opera bleichert is the patent friction grip this device is attached to every bucket and so firmly grips the cable that there is no possibility lity of slipping it also distributes the wear on the traction cable an adv tange ovee several other makes using other devices the third detail contributing toward the efficiency of the bleichert B lei C hert tramway is the automatic fastener for the buckets this is constructed so that the bucket is absolutely immovable when the clamp is down A very simple operation releases the bucket from the grip allowing a much higher speed and less wearon wear on the rope the bleichert elChert Bl in initial cost averages about 20 per cent higher than most other makes but it is claimed that operating expenses are fully 25 per cent lower and repairs and maintenance at least 50 per cent less it has been found that this tram will carry more by from 25 to 50 per cent than their rated capacity bleichert tramways Tram ways in utah there are four bleichert trams at bingham utah the oldest

carrying forty five tons hourly the yampa tram is the latest of this type to be built in bingham it extends from the mine in carr fork to the yampa smelter below the railroad station a distance of two and a quarter miles the tram is run by gravity and was built for a capacity of sixty tons an all hour but easily handles seventy five twenty three towers and four tension there are a re stations alon along g the line ranging from twelve to ninety feet in hei heights heigh gath th the rope runs at the rate of feet per minute carrying buckets stationed feet apart each one capable of transporting 1200 pounds the longest span is about 1050 feet the united states tram is two and a quarter miles long with a capacity of fifty tons hourly it has a single span of 1700 feet and is connected with a shorter tram above the buckets being transferred without reloading the utah apex has the shortest tram in the camp this being about one mile long and having a capacity of ten tons hourly this is now being increased to fifteen tons in the th e tintic gintic district of utah are two Bl bleichert elchert trams one being at the grand central mine and the other at tha th centennial eureka both are short distance trams th the former being only seven eighths of a mile in length and the latter only 1700 feet the capacity of the grand central line is twenty tons hourly the centennial eureka line was originally built for twelve and one halt half tons but was later increased to twenty and is regularly handling from thirty to thirty five the use of the tram is not restricted to carrying ore other materials such as supplies coal etc can be transported to the mine at no expense at all at the tintic gintic properties mentioned coal elevators have been installed at the lower terminals of the trams and the fuel carried to the mine and dumped at the boilers without the latest bleichert eichert BI tram to be erected in utah is that for the parleys canyon lime and stone company operating quarries near the head of parleys canyon this line is the heaviest in the state having an hourly capacity of sixty two and one half tons it is one mile long with a drop of 1200 feet the longest span
