Abstract

1419826 Mounting percussive tools DOBSON PARK INDUSTRIES Ltd 17 Jan 1974 [17 Feb 1973] 7921/73 Heading B4C [Also in Division E1] A rock breaking tool is mounted on the jib of a mobile excavating machine by means of a cradle 11 having a plate 17 mounted on tubes 18 longitudinally slidable in bearings 19 and its movements are damped by cushioning or damping material 24 on rods 20 which can be compressed between a fixed end 25, a bushing 22, 23 on the plate 17 and an end member 26 on the rod 20. The cradle is pivotally mounted on the jib and may be hydraulically moved. The damping means may be compressed, woven or interlinked steel wires or springs.
