    WEAR SYSTEMTECHNICAL FIELDThe present invention relates to a wear part system comprising a wear part holder and a wear part as well as a wear part system.
    BACKGROUND OF THE INVENTION, PROBLEMS AND PRIOR ART Various forms of dredging devices, such as summer dredgers, buckets or other types of machinesfor, mainly under water, excavating or otherwise processing or moving material or sediment using usually teeth or other replaceable wear parts or tools mounted on the cutter head, bucket or tool used to process or move the material. For machines designed to machin the material or sediment, there is in most cases wear on the teeth with which the machine is equipped. The teeth are made to be able to be replaced by post-wear and the teeth are designed to process or cut the material or sediment that is processed by the machine in different ways.
    A wear part such as a tooth is mounted on the machine, such as a cutter head on a dredger, by, for example, screw joints or wedge joints, various forms of thermal mounting such as welding or shrink joints are other pitcher mounting methods. The tooth can be mounted on a single-part holder or tool holder and replacement cellcontinuously. Forces acting on the wear part,the tool, affects the wear part holder and after a long-term use, the wear part holder may also need to be replaced. Traditionally, the wear part holder is welded, or mounted with another thermal jointing technique, to the cutter head. But it is also conceivable that the wear part holder is mounted withscrew joints, wedge joints or other mechanicalmounting method. It also happens that the tooth is mounteddirectly towards the cutter head.
    Patent document WO 2010/1110105 A2 describes a locking system for locking a stabilized denture to an adapter. The patent document describes a substantially hollow dentition made with a first opening and a second opening in which the openings are made in the grooves of the dent in which an extinction is made to enclose an adapter. cavity. When the digging tooth is arranged on the adapter, a mounting hole is defined by the first opening of the digging tooth, the cavity of the adapter, and the second opening of the digging tooth through which a locking pin can be mounted. The locking pin is mounted through the first opening, through the adapter and into the second tooth opening. The described digging tooth is made with two holes for mounting the locking pin, which means that the digging tooth is susceptible to abrasive, or other erosive or abrasive, impact of sediments with abrasive character as at workwith the toothpick will wear on the locking pin and mounting holes.
    U.S. Patent No. 5,956,874 discloses a denture device providedwith a pocket with an inner, an upper, a lower and two opposite side walls with two substantially parallel contact surfaces to prevent rotation of the trench teeth around the holder of the trench tooth. The described digging tooth is made with two holes for mounting the locking pin, which means that the digging tooth is sensitive to abrasive, or other erosive or abrasive, effects of sediment-bearing nature which when working with the digging tooth comeswear on the locking pin and mounting holes.
