A trench box, including a pair of oppositely disposed parallel elongated
sidewalls defining a work volume, distal and proximal support members
extending between the sidewalls, and a track positioned between the
sidewalls. Track adjusting members extend between the track and the
support members and a movable tram connecting plate is connected to the
track. An actuator is coupled to the track and energizable to move the
tram connecting plate and a tool module is operationally connectable to
the tram connecting plate. A pipe dispensing assembly and a gravel hopper
assembly are positionable within the working volume.
