Abstract

There is provided a lifting fixture securable to a lifting machine adapted for lifting/manipulating corresponding tier sections for assembly/disassembly of a modular auditorium including a plurality of tubes connected to a first fixture portion and a second fixture portion, the plurality of tubes adapted to be selectively secured to the lifting machine, the first fixture portion and the second fixture portion including a plurality of lifting interfaces adapted to interface with corresponding lifting interfaces of the corresponding tier sections.

First claim

What is claimed is:

1. A lifting fixture securable to a lifting machine adapted for lifting/manipulating corresponding tier sections for assembly/disassembly of a modular auditorium comprising:
a plurality of tubes connected to a first fixture portion and a second fixture portion, the plurality of tubes adapted to be selectively secured to the lifting machine, the first fixture portion and the second fixture portion including a plurality of lifting interfaces adapted to interface with corresponding lifting interfaces of the corresponding tier sections; and
wherein the first fixture portion includes a first cross member having an open end and comprises a plurality of stiffeners positioned in the open end of the first cross member between each lifting interface of the plurality of lifting interfaces.

2. The lifting fixture of claim 1 , wherein each tube of the plurality of tubes is parallel to one another.

3. The lifting fixture of claim 1 , wherein each tube of the plurality of tubes is adapted to receive a corresponding fork of a forklift machine.

4. The lifting fixture of claim 3 , wherein each tube of the plurality of tubes includes a fork tine retention feature.

5. The lifting fixture of claim 1 , wherein each lifting interface of the plurality of lifting interfaces of the corresponding tier sections correspond to a chair interface.

6. The lifting fixture of claim 1 , wherein the second fixture portion includes a plurality of beams connected to the plurality of tubes.

7. The lifting fixture of claim 6 , wherein the plurality of beams and the plurality of tubes define an L-shape.

8. The lifting fixture of claim 1 , wherein the second fixture portion is selectively separable from the plurality of tubes.

9. The lifting fixture of claim 1 , wherein the second fixture portion includes a second cross member having an open end.

10. The lifting fixture of claim 9 further comprises a plurality of stiffeners positioned in the open end of the second cross member between each lifting interface of the plurality of lifting interfaces.

11. A lifting fixture securable to a lifting machine adapted for lifting/manipulating corresponding tier sections for assembly/disassembly of a modular auditorium comprising:
a plurality of tubes parallel to one another and connected to a first fixture portion and a second fixture portion, the plurality of tubes adapted to be selectively secured to the lifting machine, the first fixture portion and the second fixture portion including a plurality of lifting interfaces adapted to interface with corresponding lifting interfaces of the corresponding tier sections;
wherein the second fixture portion including a plurality of beams connected to the plurality of tubes;
wherein the plurality of beams and the plurality of tubes define an L-shape; and
wherein the second fixture portion is selectively separable from the plurality of tubes.

12. The lifting fixture of claim 11 , wherein each tube of the plurality of tubes is adapted to receive a corresponding fork of a forklift machine.

13. The lifting fixture of claim 12 , wherein each tube of the plurality of tubes includes a fork tine retention feature.

14. The lifting fixture of claim 11 , wherein each lifting interface of the lifting interfaces of the corresponding tier sections correspond to a chair interface.

15. The lifting fixture of claim 11 , wherein the first fixture portion includes a first cross member having an open end, a plurality of stiffeners are positioned in the open end of the first cross member between each lifting interface of the plurality of lifting interfaces.

16. The lifting fixture of claim 11 , wherein the second fixture portion includes a second cross member having an open end, a plurality of stiffeners are positioned in the open end of the second cross member between each lifting interface of the plurality of lifting interfaces.

17. A lifting fixture securable to a forklift machine adapted for lifting/manipulating corresponding tier sections for assembly/disassembly of a modular auditorium comprising:
a plurality of tubes parallel to one another and connected to a first fixture portion and a second fixture portion;
wherein the plurality of tubes adapted to be selectively secured to the lifting machine, the first fixture portion and the second fixture portion including a plurality of lifting interfaces adapted to interface with corresponding lifting interfaces of the corresponding tier sections;
wherein the second fixture portion including a plurality of beams connected to the plurality of tubes;
wherein the plurality of beams and the plurality of tubes define an L-shape;
wherein each tube of the plurality of tubes adapted to receive a corresponding fork of the forklift machine;
wherein each tube of the plurality of tubes including a fork tine retention feature;
wherein each lifting interface of the lifting interfaces of the corresponding tier sections correspond to a chair interface of the corresponding tier section;
wherein the second fixture portion is selectively separable from the plurality of tubes;
wherein the first fixture portion including a first cross member having an open end, a plurality of stiffeners positioned in the open end of the first cross member between each lifting interface of the plurality of lifting interfaces;
wherein the second fixture portion includes a second cross member having an open end, a plurality of stiffeners positioned in the open end of the second cross member between each lifting interface of the plurality of lifting interfaces.
