ABSTRACT:
A moveable hydraulic aligner device, particularly suited for aligning a roadway used with a full continuous tram mining machine following a drilling cycle, comprises an upper portion, supported by wheels which allow the device to ride along the length of the roadway, to which two side portions are attached. Each of the side portions supports an extendable hydraulic cylinder which pushes against the rib of a mine tunnel to force the roadway back to the center.
