ABSTRACT:
A rotatable, vertically positioned boom support attached to a flat-bed truck. The boom support is rotatable through the use of meshed gearing powered by a reversible hydraulic motor. The boom support pivotally retains a hydraulically repositionable boom. The boom is affixed to, and supports a vertically positionable digging arm with a telescopically attached hydraulically powered digging bucket. The digging arm is structured with two slidable sections allowing the digging arm with attached digging bucket to be extended for greater reach. The slidable sections of the digging arm are repositionable through the use of hydraulic rams. One hydraulic ram is used to raise and lower the digging arm relative to the boom. The other hydraulic ram is used to raise and lower the telescopically attached digging bucket. An operator's seat and hydraulic control levers are positioned adjacent the boom support. The digging arm may be positioned vertically for digging vertical shafts, at an angle for digging trenches, or horizontal above the boom for transporting.
