ABSTRACT:
Self-propelled steerable apparatus for removing material, such as sludge, from the bottom surface of a liquid storage tank for disposition elsewhere comprises a support platform and a reversely rotatable motor-driven auger mounted below the support platform and cooperating therewith to define a space for receiving sludge when the rotatable auger is engaged with the surface. A motor-driven pump mounted on the support platform is operable to receive sludge from the auger and deliver it through a discharge hose to a remote location. Rotation of the auger delivers the sludge to the pump and propels the apparatus across the surface. A remotely controllable steering mechanism on the support platform has a tail wheel which engages the surface and steers the apparatus along a desired path. A winch-controlled back-haul cable is connected to the apparatus to periodically stop forward movement of the apparatus while the auger is still rotating so that the sludge can be more efficiently removed.
