摘要:
An anti-skid chain comprising a chain mesh (LAU) and a retaining device (HAL) which is connected thereto and which, when mounted, is connected to form a ring arranged on an inner side flank (FLA) of a tyre. A locking part (VE1, VE2) is respectively arranged on both ends of the retaining device (HAL). Both locking parts (VE1, VE2) can be connected to each other. The chain mesh (LAU) is tensed on the outer side of the tyre by at least one tensing/retaining device. The two locking parts (VE1, VE2) have a plate-type base (BA1, BA2) and can be moved into a locked position (SPO) wherein they engage with each other in a detachable manner. The base (BA1) of a first locking part (VE1) is provided with a retaining lug (NAS). Opposite-lying web-type elements (ST1,ST2) protrude from the base (BA2) of the second locking part (VE2) and are used to guide the base (BA1) of the first locking part (VE1) into the locked position (SPO).

A chain member (1) made of a d-profile steel section, that can particularly be used for a hoisting gear chain, comprises a substantially planar outer circumferential surface (3) and two side flanks (4, 5) ending in the circumferential surface, wherein each side flank comprises a planar flank section (6, 7) that is perpendicular in relation to the outer circumferential surface (3). The flank section (6, 7) is connected on each side flank (4, 5) to an outer circumferential surface (3) via a planar chamfer surface (9, 10) that adjoins the flank section, is angled towards the other side flank (5, 4) at a chamfer angle (α) in a slanted manner relative to said section.

Chain (1) having horizontal links (2a) which consist of oval profile chain links and vertical links (2b) which are hooked into the former, in which chain (1) each end web (5, 6) which connects the two longitudinal limbs (3, 4) of a vertical link (2b) to one another on an end side of the latter is supported by way of a supporting surface (8) which is formed on its inner side on a bearing surface (7) which is attached on the inner side of the associated end web (5, 6) of a hooked-in adjacent horizontal link (2a). Here, the supporting surfaces (8) are widened by the bearing surfaces (7) of all the end webs (5, 6) in each case laterally beyond the two lateral bounding surfaces (9, 10) of the relevant end web (5, 6), and supporting surfaces (8) and bearing surfaces (7) which are assigned to one another are configured in each case as mutually complementary cylinder surfaces. In a method for producing chains (1) of this type, in which method closed profile chain links (2a) are hooked into open profile chain links (2c) and subsequently the latter are closed by welding, profile chain half links (2c) are used as open profile chain links, which profile chain half links (2c) are configured as half links which are divided in the region of the middle of the longitudinal limbs (3, 4) of a chain link (2b) perpendicularly with respect to the clamping plane of the latter, and all the supporting surfaces (8) and bearing surfaces (7) which are assigned to one another are configured in each case as mutually complementary cylindrical surfaces.

With a method for producing welded round and profile chains (3) of chain links (1) that are connected to each other, the chain links (1) are produced of two chain link partial pieces (5a, 5b) each, which are connected by friction welding. The chain links (1) for round and profile chains (3) produced by this method comprise two chain link partial pieces (5a, 5b) that are connected to each other by friction welding.

The invention relates to a tensioning device (SPA) for an anti-skid chain (GLK), comprising a housing (GEH) and an actuating member (BGL). Said actuating member has at least one position, in which a tensioning strand (SPR) that can be introduced into the housing (GEH) through a housing opening can be blocked against the tensioning direction, in addition to a release position, in which the block is removed and the tensioning strand is attached to a winding reel (WKR) inside the housing, said reel being pretensioned in the winding direction and being mounted to rotate about its axis (a). A ratchet (KLR) comprising an associated spring-loaded blocking pawl, (SPK) which can be operated by the actuating member (BGL), is provided on the winding reel (WKR). Said blocking pawl (SPK) has a base body comprising two limbs (SE1, SE2), which form an angle ( alpha ), and is mounted at the intersection (SPU) of the two limbs (SE1, SE2) to rotate about an axis (b) parallel to the axis (a) of the winding reel. The actuating member is mounted to rotate about an axis (c) parallel to the axis (a) of the winding reel.
