ABSTRACT:
In a crawler track comprising at least one guide wheel and caster wheels at a track carrier, at least one driving wheel for the track, and a guide wheel tensioning device including at least one tensioning member which acts on the guide wheel via a tensioning lever supported at the track carrier, the guide wheel is provided in a guide part which is exclusively linearly moveable and is laterally supported in the track carrier with a slide block arranged between the guide part and the tensioning lever, which slide block can slide crosswise and relatively to the linear direction of movement of the guide part while transmitting the tensioning force substantially parallel to the linear direction of movement of the guide part.
