Torsion bar bracket with bushing

A system comprising:

• a lift platform comprising:
• a platform section;
• and
• a flipover, wherein the flipover moves relative to the platform section;
• a torsion bar bracket installed between the platform section and the flipover of the lift platform;
• a torsion bar disposed in the lift platform, wherein the torsion bar is attached to the torsion bar bracket at a first end of the torsion bar and attached at a first attachment point in the lift platform at a second end of the torsion bar along a length of the torsion bar, wherein the torsion bar comprises a twist between a rotatable portion and the first attachment point to reduce a pull force for moving the flipover, wherein the torsion bar is connected to the first attachment point in the lift platform using an adjustment mechanism configured for selective adjustment of a torque exerted by the torsion bar;
• a sliding bar disposed between the platform section and the flipover of the lift platform, wherein the sliding bar is connected to the torsion bar;
• and
• a bushing of the torsion bar bracket, wherein the bushing slidably receives a portion of the sliding bar and a contact surface between an outer surface of the sliding bar and an inner surface of the bushing is maintained to allow reduced sliding friction, wherein the bushing allows the sliding bar to slide relative to the torsion bar bracket, wherein the bushing comprises at least one flange to secure the bushing in the torsion bar bracket, and wherein the bushing reduces a pull force for moving the flipover;
• wherein the adjustment mechanism comprises a bracket, wherein the lift platform includes two or more different attachment points arranged in a direction that the torsion bar extends, wherein the attachment points are two or more spaced holes for engaging with the bracket, and wherein a location of the first attachment point is adjusted by moving the bracket among the two or more spaced holes of the different attachment points and engaging the bracket with any one of the two or more spaced holes.

A system comprising:

• a lift platform comprising:
• a platform section;
• and
• a flipover, wherein the flipover moves relative to the platform section;
• a first torsion bar bracket installed between the platform section and the flipover of the lift platform on a first side of the lift platform;
• a first torsion bar disposed in the platform section, wherein the first torsion bar is attached to the first torsion bar bracket via a first bushing at a first end of the first torsion bar and attached at a first attachment point in the platform section at a second end of the first torsion bar along a length of the first torsion bar, wherein the first torsion bar comprises a twist between a first rotatable portion and the first attachment point to reduce a pull force for moving the flipover, wherein the first torsion bar is connected to the first attachment point using an adjustment mechanism configured for selective adjustment of a torque exerted by the first torsion bar;
• a second torsion bar bracket installed between the platform section and the flipover of the lift platform on a second side of the lift platform, wherein the second side of the lift platform is opposite the first side of the lift platform;
• and
• a second torsion bar disposed in the platform section, wherein the second torsion bar is attached to the second torsion bar bracket via a second bushing at a first end of the second torsion bar and attached at a second attachment point in the platform section at a second end of the second torsion bar along a length of the second torsion bar, wherein the second torsion bar comprises a twist between a second rotatable portion and the second attachment point to reduce a pull force for moving the flipover, wherein the second torsion bar is connected to the second attachment point using an adjustment mechanism configured for selective adjustment of a torque exerted by the second torsion bar;
• wherein the first bushing and the second bushing reduces a pull force for moving the flipover;
• wherein the first bushing allows the first torsion bar to slide relative to the first torsion bar bracket;
• wherein the first bushing slidably receives a portion of the first torsion bar and a contact surface between an outer surface of the first torsion bar and an inner surface of the first bushing is maintained to allow reduced sliding friction;
• wherein the first bushing comprises at least one flange to secure the first bushing in the first torsion bar bracket;
• wherein the second bushing slidably receives a portion of the second torsion bar and a contact surface between an outer surface of the second torsion bar and an inner surface of the second bushing is maintained to allow reduced sliding friction;
• wherein the second bushing allows the second torsion bar to slide relative to the second torsion bar bracket;
• wherein the second bushing comprises at least one flange to secure the second bushing in the second torsion bar bracket;
• wherein at least one of the first adjustment mechanism and the second adjustment mechanism comprises a bracket, wherein the lift platform includes two or more different attachment points arranged in a direction that the first torsion bar extends, wherein the attachment points are two or more spaced holes for engaging with the bracket, and wherein a location of the first attachment point is adjusted by moving the bracket among the two or more spaced holes of the different attachment points and engaging the bracket with any one of the two or more spaced holes.
