Abstract

The invention relates to a plough chain strand 50 with horizontal chain links and vertical chain links including normal chain links 30, 40, the chain link legs of which are connected by chain link arcs and engage one another alternately in an intractable manner. In the chain strand 50 in front of and behind the chain connector link 10 is arranged in the same installation position as this at least one special chain link 20, the link legs of which comprise the same outer contour, especially the same width and the same thickness, as the outer legs of the connector link parts of the chain connector link 10. Due to the special chain links 20 preceding and trailing the chain connector link and having the same or a marginally larger contour as this, the wear of the chain connector link 10 of the chain strand 50 according to the invention is reduced or avoided if compared to known plough chains.
