ABSTRACT OF THE DISCLOSURE Apparatus lays pipe in a trench and joins successive sections thereof. An elongated carriage is of a length sufficient to straddle the trench and includes propelling means for engaging the surface outward from the respective upper sides of the trench and moving the carriage therealong. The propelling means is steerably driven. A crane arises from the carriage and includes an adjustably articulated arm of adjustable length and which has an outer end portion controllably movable both laterally with respect to the trench and between respective positions above and within the trench. The crane is mounted upon the carriage so as to permit the tilting relative thereto and, thus, relative to the sidewalls of the trench. A controllable grapple is mounted on the outer end of the arm and is controlled to engage and disengage the pipe.
