1. A multi-tool boring system comprising:
a track assembly comprising two tracks extending parallel to a primary axis of the multi-tool boring system;
a jacking frame slidably supported on the track assembly, wherein the jacking frame comprises a pair of drive supporting plates, each extending substantially perpendicular to the primary axis such that a hydraulic drive is configured to bolt to each of the drive supporting plates when the hydraulic drive is attached to the jacking frame and when a pneumatic rammer is removed from the multi-tool boring system; and
an impact plate assembly attached to the jacking frame, wherein:
the impact plate assembly comprises an impact plate and a plurality of shock absorbers forming a ring positioned between the impact plate and the jacking frame along an outer edge of the impact plate, and
the impact plate comprises an impact plate opening defined by an inner edge, configured to engage and support the pneumatic rammer when the pneumatic rammer is attached to the impact plate and partially protrudes into the impact plate opening.
