A tailgate lock-open system is provided in the form of a locking system for each tailgate opening cylinder of a rear discharging refuse collection truck body with a top hinged pivoting tailgate and having fluid-operated cylinders connected between the refuse collection body and the tailgate in which extension of the cylinder rods swings open the tailgate. The locking system includes a locking collar that can be advanced to a locking position in which it fits over a portion of a cylinder rod and has a length that determines a minimum rod extension distance. An operating assembly is provided for advancing and withdrawing the locking collar from the corresponding cylinder rod.

A steering column as set forth in claim 1 wherein said locking member has an end extending between first and second members, said locking member urging said first and second members away from each other when in said first position to urge said portion of said mounting bracket and said portion of said support toward each other to prevent movement of said support relative to said mounting bracket. 3. A steering column as set forth in claim 2 wherein said end of said locking member has a first dimension extending between said first and second members when said locking member is in said first position and a second dimension extending between said first and second members when said locking member is in said second position, said first dimension being larger than said second dimension. 4. A steering column as set forth in claim 3 wherein said locking mechanism further includes a locking shaft extending through said portion of said mounting bracket and said portion of said support, said locking shaft extending through said end of said locking member, said locking member being movable relative to said locking shaft between said first and second positions. 5. A steering column as set forth in claim 4 wherein said end of said locking member has an opening through which said locking shaft extends, said opening having first and second tapered axial ends. 6. A steering column as set forth in claim 1 further including a moving mechanism that applies said first and second forces to move said locking member between said first and second positions and an actuation lever pivotally connected with said locking member to transfer said first and second forces from said moving mechanism to said locking member. 7. A steering column as set forth in claim 6 wherein said moving mechanism that moves said actuation lever is pivotally connected with said actuation lever to move said actuation lever and said locking member between said first and second positions. 8. A steering column as set forth in claim 7 wherein said moving mechanism is a linear actuator. 9. A steering column as set forth in claim 8 wherein said linear actuator includes a piston movable within a cylinder, one of said piston and said cylinder being pivotally connected with said actuation lever, pressure being applied to opposite sides of said piston to move said piston and said cylinder relative to each other and move said locking member between said first and second positions. 10. A st
