<p>An inflatable gripper assembly for a rock boring or cutting machine is disclosed. The inflatable gripper assembly comprises a base member (42) and an elastomeric sheet (40) secured in a fluid-tight and reaction force secure manner to the base member. The elastomeric sheet expands when fluid is supplied between the base member and the elastomeric sheet to brace a rock boring or cutting machine in a tunnel. The elastomeric sheet contracts when fluid is removed from between the base member and the elastomeric sheet to allow the rock boring or cutting machine to move within the tunnel. <IMAGE></p> |
