Field Inspection & Repair

The effectiveness of Holden America Chock Systems’ ability to restrain vehicles during transit is maximized through proper inspection of the chocks. These inspections are performed at all points of the vehicle shipment process–pre-trip, loading, and unloading. Chocks deemed damaged or inoperable should be removed from the rail car and replaced with serviceable chocks of the same design, as per the AAR Office Manual, Appendix B Rule 1 . Depending on the severity of the damage on the rejected chock, it can either be repaired in the field or returned to Holden for reconditioning. The Holden America Chock Inspection and Repair Decision Matrix Standards listed below provides the OEM field inspection guidelines.
