The cross country pipe/cable laying machine (22) has a center frame (11), fitted with a number of adjustable supports (12,15) which can be set from their vertical alignment. The supports carry slides or rollers (16,19) which ride along the ground (20). A ground working unit (26) is integrated into the machine or is attached to it. A winding drum (21) has a draw hawser (23), anchored (32) into the ground to pull the machine along, or support its forward movement. |
