are connected at a moving or attached or distal end 21 to the head 14 guide 23 is attached on the stationary pipe 10 near its medial end 24 the conduit 22 is telescoped through the guide 23 the length of the conduit 22 would be about the same as the length as the moving pipe 12 if there were only a single line 20 such as a single electrical cable it could be threaded or telescoped within the conduit so that the line would hang free between the fixed or stationary base 19 and guided or proximal end 26 of conduit 22 in this location there are no moving elements to damage the line 20 also as the line 20 is free to move in this area there is no likelihood of it tangling and fouling itself it will be understood that if there were a plurality of lines such as two or four hydraulic lines that there could be two or four conduits attached to the moving base or carriage 18 and extending to the proximal end 26 if there were a plurality of conduits it is desirable that they be connected by proximal clamp 28 at the proximal end 26 so that the plurality of conduits would all remain spaced apart and parallel to one another guide 23 includes horizontal or lower roller.
