Abstract

PURPOSE: To provide the subject machine wherein the operation of a change-over for changing over air from a compression air supply source is carried out in synchronism with the inner pressure of air bags, thereby make the change-over operation accurate.
CONSTITUTION: An air inlet port of an air filter is connected to a compressed air supply source through an air hose, and is in a state where the leading end 26 of a line body 26 such as a power cable, a communication cable and the like is fitted, the self-running type line penetrating machine is set within a pipe line through a manhole. Upon this occasion, first and second air bags 4 and 80 are compressed, and with respect to a cylinder 60 a piston rod is in a moving back direction shifting limit position, whereupon the change-over valve 29 is changed over. In this manner, since the change-over value 29 is being changed over in synchronism with the internal pressure of air bags 4 and 80, the operation becomes accrurate
