The invention relates to a method of fixing a wear element () on the front edge of a support () using fixing means, where the wear element () comprises two arms () with first through openings () and the support () has a second through opening () sandwiched between the first through openings (). The fixing means comprise a C-shaped first body (), a wedge (), ratchet means () between both and a second body (), which are housed in the openings in an assembled position. The method consists of positioning the first body () and the second body () in the openings, inserting the wedge () between both, positioning a screw () between the wedge () and the second body () and screwing it in such a way that the wedge () moves with respect to the second body () and the first body () until the wedge () reaches its assembled position, and at least partially unscrewing the screw () and removing the screw () from the fixing means.

Method of fixing a wear element on the front edge of a support and corresponding fixing means

A wear element configured to be fixed on a support, where the wear element comprises two arms wrapping around the front edge of the support. The wear element being fixed with [a] a C-shaped body, [b] a wedge, [c] a screw with a shank, with a first segment having a smaller diameter than the head, a second segment having a larger diameter than the first segment, and a threaded segment, and [d] a nut. The shank of the screw is housed between the wedge and the body. The C-shaped body has a C-shaped projection suitable for housing the first segment of the screw. The projection has substantially the same height as the first segment. Neither the head nor the second segment can go through the projection. The wedge has a first projection and a second projection. Both projections have through holes suitable for allowing the passage of the threaded segment and suitable for blocking the passage of the nut, and the distance between both projection is greater than the height of the nut.

Fixing means for fixing a wear element on the front edge of a support

The present invention relates to a fixing device for fixing a wear or protection element on a bucket of an earth moving machine, comprising: a base with a housing with a front wall and a rear wall with a through hole, a stop with a lower part housed in the housing, a screw having a head going through the hole and having an end thereof fixed to the stop and a partially compressed elastic device arranged between the screw and the hole. When the elastic device is fully compressed it has a length of L. In a mounted position, the stop has a front face opposite the front wall, where the distance between both is Dand the distance between the head and the hole has a value of D, and the condition of D&#x2212;L&#x3e;Dis met in the mounted position.
