Abstract

1474598 Ripper excavators KOMATSU SEISAKUSHO KK 20 May 1974 [25 June 1973 27 June 1973 29 June 1973] 22465/74 Heading E1F An excavator comprises a mobile unit 1 having a horizontally and vertically swingable boom 6 mounted at its proximal end on the forward portion of said unit, an excavating member 16 mounted on means 15 coupled to the distal end of the boom in a manner allowing tilting of the member 16 about a horizontal axis to thereby produce an upwardly directed excavating force at the distal end of the excavating member 16 so that the member 16 can excavate both the forward face and the roof of a tunnel being excavated by the excavator, means mounted on or from said mobile unit for removing to the rear of the unit material excavated by the member 16, and means for carrying the means 15 on the boom 6 to allow of relative movement of said member 16 with respect to the boom in addition to tilting of the excavating member. The second means may comprise a boom structure 9 that is either telescopically or rotatably mounted within the boom 6.
