BRECO Ropeways
BRECO advert from the 1946 Colliery Year Book. The photo of a bicable system hints at being of an installation in a warm country.
A full description of the system shown is to be found in Meccano Magazine, June 1947, p270.
AERIAL ropeways form an ideal means of transport when comparatively light loads have to be carried across hills and dales, roads and railways, and other obstacles. They can be constructed over practically any length, the longest one in the world at present having a length of 70' miles; and they have been built to handle capacities up to 300 tons per hour. The ropeway shown in the accompanying illustrations was built, designed, and supplied by the British Ropeway Engineering Co. Ltd., London, to the Associated Cement Co. of India for use at their Bhupendra Cement Works, which are situated a few miles from Kalka, near to the foothills to the Himalayas.
The ropeway carries limestone from the quarries to the works and handles 100 tons per hour over a length of miles. It is in one straight line from end to end, no angle stations being involved; it crosses the paths of several wide rivers, a main road and a broad gauge railway. A large part of the route is through the forest of Malla, which is a hunting preserve of the Maharajah of Patiala. In designing the ropeway it was necessary to allow, over the forest portion of the route, for the buckets containing the material to be at such a height that they would easily clear an elephant and howdah.
The individual loads in each bucket on the ropeway are 14 cwt.; they move at a speed of 140 yds. per minute and are spaced about 59 yds. apart. The ropes that support the loads are of steel and are of locked coil construction, that on the loaded side of the rope¬way having a circumference of 4¾ in. and that on the return side a circumference of 3⅜ in. The rope that hauls the loads along on the track rope is 2⅜ in. in circumference. The route of the ropeway has a fall in favour of the loads and under normal conditions only about 6 h.p. is required to drive.
The photo shows a double tension station, which is provided to ensure that the correct tension is applied to the track ropes. The cages are filled with concrete blocks of the correct amount to produce this tension.It is essential that these weights should be hung freely as they have to take up any variation in the length of the rope due to temperature changes or rope stretch.
Wherever an aerial ropeway crosses a road it is usual, in order to safeguard traffic passing below, to provide some form of protective bridge or net.
