Abstract: A track section (1) adapted to be linked to a plurality of similar track sections to form a track belt for mounting around the outer periphery of vehicle tyres. The track section comprises a crossbar (11) and two lateral support members (12a, 12b). The crossbar is lattice-like and formed by two or more flat, upright and elongated crossbar elements (16) and two or more connecting elements (17). The crossbar elements (16) extend in parallel with each other and empty spaces are provided between them. Each connecting element (17) extends across and is fixed to the crossbar elements (16) in order to act as a spacer between the crossbar elements. Each connecting element (17) projects from the crossbar elements (16) on the outer side (14) of the crossbar (11).
