FASTENING DEVICE FOR WEAR PARTS IN EARTH-MOVING MACHINES AND SYSTEM

A fastening device for wear parts in earth-moving machines, related to a fastening device of the type that is arranged between two parts, components or elements of an earth-moving machine for the fastening or coupling between both parts or elements. Said device has at least one mobile blocking element and autonomous activation means of the mobile blocking element, which enable the mobile blockingelement to be activated such that, once the fastening device is inserted in a housing for this purpose in any of the parts to be coupled, the effective coupling is achieved at a certain distance fromthe fastening device, and even from the machine. 一种用于土方机械中的磨损零件的紧固装置涉及布置在土方机械的两个零件、部件或元件之间的用于紧固或联接在两个零件或元件之间的那类紧固装置。所述装置具有至少一个移动阻挡元件和移动阻挡元件的自主激活单元，自主激活单元使得所述移动阻挡元件能够被激活，使得一旦紧固装置被插入待联接零件中的任一个的出于该目的的外壳中，就实现了与紧固装置甚至与机械相距一定距离的有效联接。
