A method of cutting a microtrech in which the buried utility is exposed by opening an access hole in a roadway above the buried utility using a roadway access hole drill that rotates and vibrates the drill bit. A roadway access hole drill having a down-the-hole jack-hammer drill bit and a motor to rotate the down-the-hole jack-hammer drill.

The disclosed systems for laying underground fiber optic cable may include a drive body, at least one rotational motor, a forward auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a first rotational direction, and a rear auger element rotatably coupled to the drive body and positioned to be rotated by the at least one rotational motor in a second, opposite rotational direction. Various other systems, methods, and devices are also disclosed.

An assembly for driving excavating equipment for an excavating machine includes a drive assembly sliding along a mast of a machine, for driving the drilling equipment; and an actuator. The drive assembly includes a first structure with guide members for sliding along the mast; and a second support structure to support the drilling equipment. The first and second support structures are mutually movable. The drive assembly has at least two operating configurations, for setting at least two excavation center-to-center distances. In the operating configurations of the drive assembly, the first and second support structures are mutually rigidly and directly constrained. While switching between operating configurations, the first and second support structures are always directly mechanically constrained to each other. The actuator controls movement between the first structure and the second support structure and carries out further operative functions for driving parts of an excavating machine or drilling equipment.
