a first guide tube fixedly coupled at a first end to the first lifting bracket and coupled to a first rail beam at a second end; and

a second guide tube fixedly coupled at a first end to the second lifting bracket and coupled to a second rail beam at a second end;

wherein at least one of the first and second jack screw connectors further comprises a pair of clevises, and a guide block coupled to each of the clevises by fasteners orthogonally oriented with respect to each other.

2. The lifting bracket assembly system of claim 1 , further comprising a keyway on each of the first guide tube and the second guide tube, extending from each of the second ends.

3. The lifting bracket assembly system of claim 2 , further comprising:

a first guide bracket that slidably engages with the first guide tube, wherein the first guide bracket includes a first guide bracket key;

a second guide bracket that slidably engages with the second guide tube, wherein the second guide bracket includes a second guide bracket key;

wherein the first and second guide bracket keys slidably engage with the keyways of the first and second guide tubes.

4. The lifting bracket assembly system of claim 3 , wherein at least one of the first and second guide brackets further comprises a channel for receiving the guide tube.

5. The lifting bracket assembly system of claim 1 further comprising at least one positional switch physically linked to the first and second lifting brackets.

6. The lifting bracket assembly system of claim 1 , wherein at least one of the first and second lifting brackets further comprises:

a cavity for receiving the first end of the guide tube; and

a jack nut for rotatably coupling one of the first and second jack screws.

7. A lifting bracket assembly, comprising:

a frame;

a motor supported by the frame;

at least one drive transmission system coupled to the motor;

at least one jack screw connector coupled with one of the drive transmissions;

at least one jack screw coupled to one of the jack screw connectors;

at least one lifting bracket rotatably coupled to one of the jack screws;

at least one guide tube fixedly coupled at a first end to one of the lifting brackets and slidably engaged at a second end with a guide bracket on the frame;

wherein the jack screw connector further comprises a pair of clevises, and a guide block coupled to each of the clevises by fasteners orthogonally oriented with respect to each other.

8. The lifting bracket assembly of claim 7 , further comprising a keyway on the guide tube extending from an end distal to the first end and a guide bracket key located on the guide bracket, wherein the key slidably engages with the keyway.

9. The lifting bracket assembly of claim 7 further comprising at least one positional switch located on the frame, wherein the positional switch physically links the frame to the lifting bracket.

10. The lifting bracket assembly of claim 7 , wherein the guide bracket further comprises a channel for receiving the guide tube.

11. The lifting bracket assembly of claim 7 , wherein the lifting bracket further comprises: a cavity for receiving the first end of the guide tube; and a jack nut for rotatably coupling the jack screw.

12. A method for assembling a lifting bracket assembly, the lifting bracket assembly including a frame, a guide bracket supported by the frame, a jackscrew connected to a jackscrew connector and gearhead, the gearhead connected to the frame, comprising:

coupling a pair of clevises and a guide block using fasteners orthogonally oriented with respect to each other to form the jackscrew connector;

aligning and rotatably coupling a lifting bracket to the jack screw;

slidably aligning a guide tube with a guide bracket, the guide tube having a first end and a second end opposite the first end for supporting a beam; and

aligning and fixedly connecting the guide tube at the first end to the lifting bracket.

13. The method of claim 12 , wherein aligning and rotatably coupling a lifting bracket to the jack screw further comprises rotatably securing the lifting bracket to the jack screw with a jack nut.

14. The method of claim 12 , wherein slidably aligning a guide tube with a guide bracket, further comprises: aligning and slidably engaging a guide bracket key located on the guide bracket with a keyway on the guide tube extending from an end distal to the first end.

15. The method of claim 12 , wherein aligning and fixedly connecting the guide tube at the first end to the lifting bracket further comprises: receiving the first end of the guide tube in a cavity in the lifting bracket; and securing the first end of the guide tube to the lifting bracket.

16. The method of claim 12 , further comprising physically linking the frame to the lifting bracket with a position switch.
