Abstract
A track maintenance machine with a conveyor or excavating chain arrangement for removing and collecting railway ballast and/or other formation or substructure layers of a track structure is shown, comprising a cutter bar which can be positioned below a track and which has at least two bar elements, each adjustable in position and alignment, and which is attached to an ascent channel and to a return channel. The device comprises a guided excavating chain consisting of a plurality of chain links, wherein the arrangement can be fastened to a machine frame via at least one height-adjustable suspension device. The excavating chain is designed to be divisible, that the bar elements can be connected via a coupling to form a closed overall unit, and that the arrangement can be variably adjusted in its excavating working width by adjusting the position of the bar elements.
