ABSTRACT:
A trailer restraint positively restrains a trailer against a dock by means of the trailer ICC bar. The trailer restraint is self-aligning with an ICC bar located anywhere within its range of operation. The trailer restraint comprises a shoe that pivots on a trunnion shaft within a housing located under the trailer ICC bar. The trunnion shaft is slidable within the housing against a strong spring. A hydraulically operated slider advances to pivot the shoe until a working surface thereof contacts the trailer ICC bar. Further advancement of the slider causes the shoe to pivot about the contact point of the shoe on the ICC bar, thereby sliding the trunnion shaft until the shoe working surface is aligned with the trailer ICC bar. A lock bar received on the trunnion shaft slides therewith. A pawl engages teeth on the lock bar to prevent further sliding of the lock bar and trunnion shaft. Various switches sense the location of the shoe and lock bar and are incorporated into an electrical circuit to display the status of the trailer restraint to nearby personnel.
