The Mechanical Handling and Storing of Material

ROPE WA YS 3°5 per hour, and the inclines about 1 in 5. There are a hundred buckets in use, Fig. 443. Delivery Station of a Ropeway for Ore in Northern Chile. supported on eight trestles, the highest of which is 77 illustration, Fig. 444, shows one of the high trestles. Amongst other installations erected by this firm, perhaps the most interesting is that at Clee Hill, Shropshire, used for transporting broken stone from a quarry to the railway. This ropeway, which is also on the single rope system, is the longest of its type in this country. It is about 3| miles in length, and is capable of conveying about 60 tons of material per hour in individual loads of about 10 cwt. The ropeway is arranged in two straight lines connected by means of an angle station. A secondary ropeway, about 230 yds. in length, with a series of short shunt rail sidings, is erected at the quarry for facility in loading the stone into the skips. Storage bins of large capacity are provided at the unloading terminal into which the material is discharged direct from the skips suspended on the terminal shunt rail. The material is discharged direct from the storage bins to the railway wagons as required. There are altogether '270 skips in use supported on fifty-five trestles, varying in height from 30 to 60 ft. Installation by Ernst Heckel An unusual ropeway installation for the dis- posal of furnace slag was erected by Ernst Heckel for the Röchling Works at Völklingen in 1910, and the delivery terminal above the spoil heap is shown in Fig. 445. This station is supported by a ferro- concrete mast 3 m., or nearly 10 ft., in diameter, and ft., whilst the lowest is 24 ft. The Fig. 444.
