Abstract:
1. An anti-creep locking mechanism for a suspension of a trailer, comprising: a frame having at least two longitudinally-extending rail members and at least one cross member extending transversely between and being attached to said rail members; at least one column member sub-assembly comprising a pivotable column member having a pivoting end and a contact portion, a spring and said column member being mounted on a rotatable shaft, said rotatable shaft connected to a base member, said base member mounted on at least one mounting structure selected from the group consisting of said at least one cross member and said rail members, the column member being selectively positionable between a first position, wherein said contact portion is pivoted downwardly and away from said mounting structure, and a second position wherein the contact portion is pivoted upwardly and toward the mounting structure, said contact portion being disposed laterally inboard when said column member is in said second position, said spring biasing the column member into said first position; and an actuator assembly for overcoming said spring biasing of said column member to pivot the column member into said second position, whereby when said column member is in said first position, said frame is maintained at a predetermined height to prevent creep of said trailer.
