Abstract
A trailer slider system includes a body rail that slides longitudinally relative to a suspension frame side rail. One of the rails includes holes that provide multiple suspension positions. The trailer slider system also includes a pin connection assembly having a pin that is arranged to extend into one of the holes in a locked position and retract out of the hole in an unlocked position. A cam is coupled for movement with the pin connection assembly. A tube is coupled with the cam to rotate as the pin moves between the locked and unlocked positions. A pneumatic actuator is coupled with the tube for selectively rotating the tube to move the cam which in turn moves the pin, between the locked and unlocked positions.

A trailer slider system including a body rail that slides longitudinally relative to a suspension frame side rail, one of the body rail or the suspension frame side rail including holes that provide multiple suspension positions, the trailer slider system comprising:
- a pin connection assembly having a pin that is arranged to extend into one of said holes in a locked position and retract out of one of said holes in an unlocked position;
- a cam coupled for movement with said pin connection assembly;
- a tube supported by a slider support structure, said tube coupled with said cam to rotate as said pin moves between said locked position and said unlocked position;
- and
- a pneumatic actuator coupled with said tube for selectively rotating said tube to move said cam to move said pin between said locked position and said unlocked position.
A trailer slider system including a body rail that slides longitudinally relative to a suspension frame side rail, one of the body rail or the suspension frame side rail including holes that provide multiple suspension positions, the trailer slider system comprising:
- a pin connection assembly;
- a pin associated with said pin connection assembly, said pin is arranged to extend into one of said holes in a locked position and retract out of one of said holes in an unlocked position, said pin including an end that extends through one of said holes in said locked position, said end having an end surface including an end feature selected from at least one ramped portion and at least one stepped portion;
- a pneumatic actuator operatively connected with said pin connection assembly for moving said pin between said locked position and said unlocked position;
- a pneumatic parking brake to be associated with a trailer carrying said trailer slider;
- and
- a pressurized gas supply fluidly connected with said pneumatic actuator and said pneumatic parking brake.
