Abstract

An assembly for shipping and supporting a module for a heat recovery steam generator comprises a base having four vertical truss members slidably mounted to the base at one end. Each vertical truss member is positioned a distance apart from another vertical truss member across the base such that four paths of adjacent vertical truss members define a front, a back and two sides. The assembly further comprises at least one level. Each level comprises a horizontal member rotatably attached to the vertical truss members at the front and the back of the assembly. A junction is fixed to each vertical truss member at both sides of the assembly; a side truss member is rotatably attached to the junctions at both sides. An internal grid is attached to the horizontal truss members between the vertical truss members. Diagonal truss members are removably attached to the junctions at both sides of the assembly between adjacent levels such that the diagonal truss members diagonally extend from the junction of one level to the junction of an adjacent level.

Claims

1. An assembly for supporting an arrangement therein, the assembly comprising:

a base;

four vertical truss members slidably mounted to the base at one end of the members, each vertical truss member positioned a distance apart from another vertical truss member across the base such that four adjacent vertical truss members define a front, a back and two sides;

a plurality of levels comprising front and rear horizontal members rotatably attached to the vertical truss members, a junction fixed to each vertical truss member at both sides, horizontal side truss members rotatably attached to the junctions at both sides, an internal grid attached to the front and rear horizontal members between the vertical truss members; and

a diagonal truss member removably attached to the junctions at both sides between adjacent levels, the diagonal truss member diagonally extending from the junction of a level to the junction on an adjacent level.

2. The assembly according to claim 1, wherein the front and rear horizontal members are rotatably attached to the vertical members by securing means.

3. The assembly according to claim 1, wherein the horizontal side truss members are rotatably attached to the junctions by junction securing means.

4. The assembly according to claim 2, wherein the securing means comprises a pin.

5. The assembly according to claim 3, wherein the junction securing means comprises a pin.

6. The assembly according to claim 1, wherein the assembly includes a diagonal support attached to the vertical members at the front and diagonally extending between adjacent levels.

7. The assembly according to claim 1, wherein the vertical and horizontal members are made of standard rectangular structural tubing.
