摘要

A tool carrier is hinged to one or more jib arms, and a striker head moving on a sliding carriage on it, with a front piece to hold the inserted end of a chisel, on the loading machine. The front piece (3a) is formed to accommodate the inserted end of the box part of a box scoop, or the inserted end (67) of a shell scoop (68). In the case of the former, its unloading slide (53) may be coupled to the tool carrier (16) via a connecting element (54). The insertion end may be detachably connected to the box or scoop.
