Abstract
1,146,696. Mineface conveyers. GEWERKSCHAFT EISENHUTTE WESTFALIA. 22 March, 1966 [22 March, 1965], No. 12527/66. Heading B8A. In an advancing system for a longwall conveyer 23 which discharges on to a feeder conveyer 3 having a reinforced channel section 2, a prop 14 is connected to one side of the section 2 by a shifting device 5 and a prop 4 is connected at a pivot 16 to the same side of the section 2. To the other side of the channel section is pivotally connected a sled 8 which slides on an anchor beam 10 associated with the longwall conveyer 23. A shifting device 6 connects the prop 21 with the sled 8. In operation, props 14, 21, 22 are hydraulically set against the roof, prop 4 is retracted, and the shifting devices 5, 6 are extended together by means of a common fluid supply. Follow-up of the beam 10 then results from retraction of the props 21, 22 and the device 6, after props 4, 14 have been set.
