Abstract

1277957 Earth working machines G FUCHS and U THIERER 1 Oct 1969 [1 Oct 1968] 48275/69 Heading E1F A machine such as a digger comprises a beam 5 pivotally supported on a frame 1 by crossed members 7, 9 and operated by a ram 4. A ram operated lever 12 on the beam carries a digging-tool such as a grab 14. The member 9 may be a rod as shown or may be a ram, Fig. 2 (not shown). The machine may be such that the digging tool is moved in the horizontal direction instead of the vertical direction as shown.
