An excavating and pipeline installation system includes an excavating vehicle, an excavating wheel assembly and a plurality of conveyors. The excavating wheel assembly includes a pair of excavating wheels for excavating a pipeline receiving trench at a predetermined location beneath the surface of the earth. The excavating wheel assembly is supported at the front end of the vehicle on a subframe mounted for pivotal movement relative to the vehicle between excavating and traveling positions. The excavating wheels are mounted for rotation about angularly disposed axes and are positioned to receive the pipeline therebetween. Bolster rollers are mounted on the excavating wheel assembly for initially lifting the pipeline, and pipeline rollers are mounted on the vehicle for exerting a downwardly directed force on the pipeline upon insertion thereof into the pipeline receiving trench. The conveyors include a main conveyor mounted on the subframe for receiving material from the excavating wheels and for transporting the excavated material upwardly and rearwardly. A plurality of trailers are adapted for connection to the rear of the vehicle, and each trailer includes a conveyor for receiving the excavated material and for transporting the excavated material rearwardly. The excavated material is ultimately redeposited in the pipeline receiving trench subsequent to the positioning of the pipeline therein.
