     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The following discussion describes in detail one embodiment of the invention (and several variations of that embodiment). This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims. 
     Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,  FIGS. 1 through 15  illustrate the frame straightening device of the present invention which is indicated generally by the reference numeral  10 . 
     In the motor vehicle industry it is known that trailer frames bend out of shape over time due to heavy loads and wear. It is desirable to have a device to easily fix the bent frame of a trailer rather than purchase a new trailer frame. The present invention aims to provide a system to fix bent trailer frames by bending them back into a desired shape. 
       FIG. 1  is an illustrative view of the application of frame straightening device of the present invention. A cargo unit  12  is transported by a trailer bed frame  14 . The cargo unit  12  is generally placed onto the trailer bed frame  14  by a pulley system  13 . Instances of negligence or malfunction of the pulley system  13  can cause a bending of trailer bed frame  14  out from its original and most effective state. The force of a premature drop, caused by the breaking of a pulley or negligence by its operator, of cargo unit  12  of trailer bed frame  14  will exert enough force to bend trailer bed frame  14 . Additionally, the trailer bed frame  14  may bend from wear over time or transporting cargo units  12  which exceed its weight limits. 
       FIG. 2  is an illustrative view of the application of the frame straightening device of the present invention. Cargo unit&#39;s  12 , as shown in  FIG. 1 , are transported by means of trailer bed frame  14 . Over time the beams  16  of trailer bed frame  14  bend out of shape and the level of support the cargo unit  12  can provide is dampened. Desired level  15 , shown herein as dotted lines, indicates the level at which the beams  16  of trailer bed frame  14  once were positioned. The present invention aims to bend the beams  16  of trailer bed frame  14  back the desired level  15 .

Support members  28  extend from support base plate  26  at identical angles to a predetermined location on each respective stanchion  22 . Support members  28  provide equal force on each side of stanchions  22  to help create a solid supported structure. The upper support  24  is connected at each distal end thereof to a distal end of each stanchion  22  opposite the first distaldistal end. The support  24  connects both stanchions  22  to one another. This connection provides support in a direction perpendicular to the support members  28 . 
     Both upper support beam  24  and stanchions  22  contain tracks positioned on an inner surface thereof. Hydraulic rams  30  are attached within these tracks on the stanchions  22  and upper support beam  24 . The tracks are available to guide movement of the attached hydraulic ram  30  in a parallel direction along the length of the respective stanchion  22  or upper support beam  24 . This connection will be discussed in detail in reference to  FIG. 14 . Force from the hydraulic rams  30  is exerted on trailer bed frame  14 , shown in  FIG. 4 , to bend frame  14  into a desired shape. The forces will be discussed in greater detail in reference to  FIG. 7 . 
     A track  32  is positioned at each end of the floor guide  18 . The direction of the track runs parallel to the upper support beam  24 . To focus the force exerted by the hydraulic rams  30  at the center, securing posts  20  are positioned within track  32 .

       FIG. 15  is a flow diagram of the user process of operation of the present claimed invention. The straightening device of the present invention aims to correct the shape of a trailer bed frame that has bent out of shape. To start the frame straightening process the user first inserts the bent trailer frame onto the floor guide in step S 100 . The user then powers on the system in step S 110 . When powered, the side hydraulic rams pan downwards into a level position. The trailer frame is secured in step S 120  by securing posts and fastening elements. At this point the trailer frame is ready to be straightened. Each hydraulic ram desired for use must be powered on as in steps S 130 , S 140  and S 150 . Once powered, the position of the hydraulic ram can be adjusted in step S 160  so the powered hydraulic ram may be at the same level as the trailer frame. A shoe may be attached to the hydraulic ram in step S 170  to spread the force exerted over a larger area. Once positioned and ready, the hydraulic ram is responsive to a strength input set in step S 180 . This setting increases and decreases the amount of force exerted on the frailer frame from the applicable hydraulic ram. Upon the completion of use of the powered hydraulic ram, the hydraulic ram is powered off as in step S 200 , S 190  and S 210 . Upon completion of the use of all hydraulic rams the system may be powered off in step S 220 . Upon powering the system off the side hydraulic rams pan up to make it easier to remove the trailer frame.
