Abstract: For use especially in underground mining and tunnel construction, a steel link chain is provided that is composed of vertical and horizontal links and pushers. The vertical and horizontal links are formed by two parallel chain link arms and by chain link arches connecting them. The chain link arches are designed in a concave shape in the mutual roll-off area so that a surface contact is achieved. In addition, the chain link arches of the horizontal links have horizontally and vertically extending arrow surfaces that enable a safe surface contact in the area of the chain wheel that is constructed as a double helical wheel. The horizontal links furthermore are constructed in the area of the chain link arms like a groove, so that a form-fitting connection with the pusher is achieved, contributing to a significant improvement of operating characteristics and longer service lives.
