Auto-rack railroad car vehicle restraint apparatus

摘要

A vehicle restraint system for an auto-rack railroad car which includes an active chock and an anchor chock configured to co-act to secure a vehicle in the auto-rack railroad car. In various embodiments, each chock has a chock body including a substantially diamond shaped elongated tube which includes four integrally connected elongated walls. In various embodiments, for each chock, various components of that chock extend substantially along longitudinal axis that lie in the same or substantially the same vertical plane as the apex and trough of the substantially diamond shaped elongated tube of the chock body. The active and anchor chocks: (a) have a lower height than known commercially available vehicle restraints; (b) have a smaller width than known commercially available vehicle restraints; (c) position the strap and the torque tube closer to the tire of the wheel than any known commercially available vehicle restraints; (d) take up a smaller area of each safe zone adjacent to the wheel than known commercially available vehicle restraints; (e) provide a greater strength to size ratio than known commercially available vehicle restraints; and (f) are easy to operate, install, and remove.
