Abstract

A device for transferring the debris cut by a cutting machine during mining operations onto a drift conveyer comprises a pair of bridge conveyers connected to each other. The first bridge conveyer has its receiving end pivotally connected to the cutting machine with its discharge end being supported by a dirigible chassis. The second bridge conveyer is supported on the chassis of the first conveyer and pivotable about its horizontal and vertical axis. The support chassis is capable of being swivelled around a vertical axis relative to the first bridge conveyer.
