Abstract

1334543 Mining machines; excavators DOBSON PARK INDUSTRIES Ltd 8 Nov 1971 [18 Nov 1970] 54722/70 Heading E1F A vehicle mounting a universally moveable boom for supporting a rock, earth or hard materials - displacing tool has for its propulsion over ground at least three ground-engaging members that each extend longitudinally of the machine and of which two can be displaced relative to the remaining member or members in said longitudinal direction and can be moved independently of one another to permit of steering of the vehicle. Preferably the members comprise two open bottomed beams 12 attached to the underside of the chassis of the vehicle and, in each beam, a sole plate 27 carrying a plurality of hydraulically extensible members 28 which act on the underside of the associated beam 12 through levers 29 pivotted on the beam. The beams may be of H cross section and blanked off at the ends to form with the chassis of the machine closed reservoir tanks for hydraulic fluid for hydraulic power circuits of the machine. The. tool may be a reciprocated chisel or a digger wheel. Specification 1314029 is referred to.
