  • Patent number: 9950581
    Abstract: The invention relates to an anti-skid chain, in particular for forestry and agricultural vehicles. The anti-skid chain is to permit high traction, while it has a low weight and can be easily mounted. It should simultaneously be permitted for driving on roads. To enable this, an anti-skid chain to be attached to two wheels with tires disposed one behind the other at fixed distances, in particular for the two wheels of a tandem axle, is provided according to the invention. The anti-skid chain comprises two lateral, laterally stable guide chains which are located, in the mounted state, laterally of the tread of the tires. Between the two guide chains, a chain mesh with chain strands extends. Preferably, the chain mesh is subdivided into ladder sections which are only connected to each other via the guide chain. Joint points of the guide chains are located in a radial position between the radius of the tire shoulder and the tire center. The guide chains are in particular embodied as plate link chains.

  • Patent number: 9234564
    Abstract: The present invention relates to a closure assembly (1, 1?) for closing a connecting link (100) of a tire chain, comprising at least one closure element (10, 10?) that has at least one leg reception member (14, 14?) configured to receive therein, at least sectionwise, a leg (101) of the connecting link (100). In addition, the present invention relates to a connecting link (100) for connecting at least two links of a tire chain, comprising two legs (101) that are interconnected via a yoke (108) as well as to a tire chain, in particular a tire protection chain.

  • Patent number: 9108475
    Abstract: The invention relates to a locking plate (1) for tensioning a tire chain by means of a ten-sioning chain (46), and to an arrangement, comprising a locking plate (1) and a pull-through bracket (40). The locking plate comprises a locking slot (10) whose clear width is greater than a thickness and smaller than an outer width of the chain links (34) of the tensioning chain, and with a pull-through opening with an inner contour into which an outer contour of the tensioning chain can be entered. The tensioning chain can be captively received in the locking plate transversely to its longitudinal extension to be movable between a locking position (18) arranged in the region of the locking slot and a pull-through position (16) arranged in the region of the pull-through opening.
