ABSTRACT:
An oil well cuttings disposal tank apparatus of improved construction provides a tank body having an interior and a plurality of side walls, a plurality of end walls, a bottom wall, and a top wall with a discharge opening at one end portion thereof. The discharge opening communicates with the intersection of the top wall and one of the end walls. A hatch is provided for opening and closing the discharge opening. A plurality of lifting plates are attached to the side walls and extend upwardly from the top wall, each of the lifting plates having openings or eyelets for attaching lifting lines thereto. A stacking beam is associated with each lifting plate, each stacking beam extending from the top wall upwardly a distance and attaching to the lifting plate at a position above the top wall. Each stacking beam has a load bearing surface that extends laterally from its lifting plate inwardly toward an opposite stacking beam and the central portion of the tank. A pair of slots on the lower end portion of the tank body at the bottom wall are provided, the slots being shaped to conform to and nest upon the bearing surfaces of the stacking beams when one tank body is nested upon another similarly configured tank body. Upper portions of the lifting plates prevents sliding of one tank relative to the other tank in a "X" direction. The connection between stacking beams and lateral slots prevent sliding of one tank stacked upon another tank in a "Y" direction.
