<p>PURPOSE:To raise the efficiency of operation by providing a conveyer with pipes through which an oil-pressure hose and a power source cable are thrust, a crane by which carries pipes on the conveyer into a presser device, and an elevator for hose and cable. CONSTITUTION:A portal crane 30 is set above a vertical pit 10, a rail 34 is set from above a presser 12 to the tip of a roller conveyer 36, and a pipe 18 is hung down through a hook 32. The pipes 18 thrusting an oil-pressure hose and power source cable 24 are set in series on the conveyer 36 and carried into the presser 12 one after another. A hose and cable elevator 38 is provided to the back end of the conveyer 36 to hold the intermediate part of the cable 24 in air. A necessary number of the pipes 18 for the day are set on the conveyer 36 and the excessive portion of the cable is held in air by the elevator 38. The space of operation can thus be reduced.</p> |
