ABSTRACT:
A mobile hydraulic hoist unit which is readily maneuverable to a position straddling a load and then conveniently operated to lift and securely transport such load over a variety of terrains and surfaces and to safely and accurately deposit that load at a specific location. The hoist unit comprises a generally “U” shaped base frame having spaced side members provided with multi-terrain wheel assemblies, a closed forward end having a hitch member for releasable attachment to a towing vehicle, a rearwardly open center section adapted to receive and straddle the load, a power cylinder, a boom operated by the power cylinder for lifting and securely holding the load in a transport position during movement of the hoist unit and for accurately depositing the load at the desired destination. The invention also includes but is not limited to the use of removable support means to assist in supporting and stabilizing the load during movement of the hoist unit, and the use of boom assemblies which are mounted on fixed and swivel bases.
