Railroad car coil restraint system
A transverse railroad coil car coil restraint apparatus or system which includes a plurality of coil restraints attachable to each trough in a transverse railroad coil car to reduce the sideways shifting of coils positioned in the troughs. In certain embodiments, the coil restraints are attached in each trough and extend across the transverse coil car. In other embodiments, the coil restraints are attached in each trough along the length of the trough. In certain embodiments, when a coil is positioned in the trough, the coil compresses certain of the coil restraints and does not compress other of the coil restraints which prevents the sideways shifting of the coil during movement of the transverse coil car. In other embodiments, when a coil is positioned in the trough, the coil compresses certain of the compression members and does not compress other of the compression members which prevents the sideways shifting of the coil during movement of the transverse coil car.
1. A railroad car coil restraint system for a transverse railroad coil car having a trough, said trough including a front wall and a back wall and configured to hold a coil, said railroad car coil restraint system comprising:
a plurality of coil restraints, each coil restraint having:
