does not adequately cope with the special stresses that occur when the chain is used. The innovation is based on the "task" of remedying this deficiency and developing a glide protection chain which is particularly resistant to alternating impact-bending stresses. This task is achieved in that the chain strands are oval in a manner known per se Round steel links are formed, and that _: at least all of the chain and coupling links which are arranged in the tensile structure of the Ijaufnetzes and come into engagement with the roadway have a maximum inner length or width of 3 d, where d is the round steel diameter.

The chain according to the innovation offers · the gate part, .that the. Impact-bending fatigue strength of their links due to the "." The proposed η compact design is very high and thus a long service life of the consistently deep-case hardened components is achieved. The service life is also beneficial if, in an anti-skid chain according to the invention for off-road tires with cleats arranged in the edge area, the running net in the cleat area is provided with track pieces, the length of which: preferably at least 1.2 to 1.5 times larger than the width of the gap between the tunnels. In this way a sudden hooking of the links of the track pieces in the gaps is prevented. that the track pieces in the land portion arranged transversely to the chain, the horizontal links between the vertical members comprehensive, of oval chain links: have transverse webs formed.

The innovation will be explained below with reference to an exemplary From guide die facing accompanying drawings.

In the drawing, 11 are the vertical links and 12 are the horizontal links of chain strands 15, 145, 15 »16 and which are connected via ring-shaped coupling links 18, each of which is connected to three chain strands. The outer chain strands 16 each have a hook 19 at one end, by means of which they are connected on one side of the anti-skid chain to a retaining chain 20 which can be tensioned by means of a tensioning chain 21 to which it is connected via hinge. On the other side of the chain, the hooks 19 are hooked into a retaining chain 23. y: _■: ::

All members 11, 12 and 18 of the renovation. Anti-skid chains have an inner length or width of a maximum of three times the fenndieke d des for their manufacture used dog steel material. The inner width of the oval links 11, 12 is only-at most 1.3 d. .

The track pieces forming chain strands 17, which 1,2 to; : 1.5 times as long as the crooks between the lateral tunnels of off-road tires, in order to be able to hike over or bridge them without getting stuck, wear crossbars 24, which also allows you to hike over gaps in tunnels promote and at the same time the gripping ability of the chain;.: raise.

On the chain strands I3, 14 transverse webs 25 are attached, in an arrangement offset over the running surface.
