Abstract

A sludge pond vehicle, for use with an onshore waste processor, includes a frame to which a pair of elongate, generally cylindrical pontoons and a trash pump are mounted. Each pontoon has a spiral flight about its outer surface and each is individually driven about its own axis so to propel the vehicle through a sludge pond. The frame includes pivotal support arms at each end between which the elongate pontoons are mounted. Pivoting the support arms relative to one another causes the pontoons to separate and approach each other thus raising and lowering the trash pump. High pressure hot water is sprayed into the sludge pond in the region of the trash pump to aid removal of the sludge. The various power and control lines are carried by an overhead boom pivotally mounted to the frame. The boom can pivot freely over an arc of about 270.degree. to permit relatively unrestricted movement of the sludge pond vehicle.
