ABSTRACT:
A pipe handling device with an auxiliary pipe loading device for use with a horizontal boring machine is disclosed. The auxiliary pipe loading device includes an auxiliary pipe receiving member that is connected to a pipe handling assembly at a location remote from the boring machine. The pipe receiving member is adapted to receive and support a pipe section when the pipe handling assembly is retracted such that the auxiliary pipe receiving member is positioned beyond the magazine of the pipe handling device. The auxiliary pipe receiving member is pivotally connected to a lockout assembly that is operable between a closed position and an open position. In the closed position, the lockout assembly prevents a pipe section from entering the auxiliary pipe receiving member. Whereas in the open position, the lockout assembly permits a pipe section to be manually placed in the auxiliary pipe receiving member. Additionally, an axial stop is provided as a mechanical guide for properly aligning the pipe section axially with the magazine.
