Abstract: A pipe laying machine for laying a pipe in a trench, includes a first self-propelled chassis (10) on which a driver's cab (11) and powertrain (12) are located, a beam (20) connected at a first end (20a) to the chassis and which extends laterally therefrom, a second moving chassis (30) connected at a second end (20b) of the beam and a guiding and supporting element (40) of a pipe, sliding on the beam toward and away from the self-propelled chassis, in which the self-propelled chassis can travel on a track (P) at the edge of the trench, the moving chassis (30) can travel on the bottom of the trench, and the guiding and supporting element can translate to carry the pipe to the trench so that by moving the machine forward along a direction of forward movement the cantilevered portion of pipe is laid on the bottom of the trench.
