Utility vehicle tyre chain having at least one cleat plate, utility vehicle tyre and cleat plate for a utility vehicle tyre chain

A utility vehicle tire chain, in particular for forestry vehicles, tractors, or wheel loaders, has a plurality of cleat plates directly or indirectly connected to one another via chain strands, wherein each cleat plate has at least one cleat to improve traction which extends away from an upper side of the cleat plate. The solution according to the invention can simplify the manufacture of a utility vehicle tire chain and improve its stability.

Wheels with controllable suction devices for adhesion on surfaces

Wheels have controllable suction devices for adhesion on surfaces. The wheel has an axle and an outer circumferential surface. The outer circumferential surface has a plurality of apertures and a plurality of stretchable materials. Each aperture has a respective stretchable material therein. Rotating the wheel moves a first stretchable material adjacent to a surface of a structure. A portion of the first stretchable material moves in the direction radial to the axle, to control adhesion of a portion of the outer circumferential surface to the surface of the structure. A method implements use of the wheel to adhere to the surface of the structure.
