Abstract:
1. A tank container adapted to rest on an external support, the tank container being adapted to be raised by a hoist, rigged with suitable hoist rigging, the tank container comprising: a base adapted to rest on the external support; a tank barrel supported by the base relative to the external support, the tank barrel having a continuous sidewall, the tank barrel having a longitudinal axis extending in a substantially horizontal direction, the tank barrel having a flange, the flange oriented in an upright position extending upward from the sidewall in a vertical direction relative to a vertical flange axis, the tank barrel being suitable to contain fluid material; an open frame joined to the base in spaced relation to the tank barrel, the frame defining a space about the tank barrel; an open protective structure supported by the frame, a major portion of the open protective structure defining a protective structure plane, the protective structure plane extending in a horizontal direction perpendicular to the vertical flange axis, the protective structure plane being located above the sidewall, the open protective structure being spaced from the vertical flange axis, the open protective structure being spaced from the flange, the open protective structure being spaced from the open frame in the direction of the vertical flange axis, the open protective structure impeding contact between the flange and an external structural agent occupying a position above the open protective structure, the open protective structure impeding contact between the sidewall and an external structural agent occupying a position above the open protective structure, the open protective structure impeding contact between the flange and an external structural agent occupying a position outside the open protective structure in a direction perpendicular to the vertical flange axis; hoist engagement structure adapted to receive the hoist rigging, the hoist engagement structure including a plurality of eyes supported by the frame, each eye being adapted to receive hoist rigging, each eye being located in a respective first vertical plane, the first vertical plane being parallel to the vertical axis, the first vertical plane being spaced apart from the vertical flange axis by a first distance, each eye being located in a respective first horizontal plane, the first horizontal plane being perpendicular to the first vertical plane; and rigging protective structure supported by the frame, the rigging protective structure including a plurality of protective crowns each located in proximity to a respective eye, each protective crown being located in a respective second vertical plane, the second vertical plane being parallel to the first vertical plane, the second vertical plane being spaced apart from the vertical flange axis by a second distance, the second distance being greater than the first distance, each protective crown being located in a respective second horizontal plane, the second horizontal plane being parallel to the respective first horizontal plane, the second horizontal plane in the vertical direction being located above the first horizontal plane.
