Aldon® manufactures the best steel railcar wheel chocks, one of which is the Single Railroad Wheel Chock w/ Flag (Exposed Rail). Aldon Company is the originator of modern-day chocks with spurs. Our chocks are built with all-steel construction and have replaceable rail-biting spurs that provide exceptional holding power for securing freight cars and locomotives. They work on a broad range of rail sizes (75 lbs./yd. to 141 lbs./yd.) and wheel diameters (28″ – 44″). Tested successfully to withstand over 25,000 lbs. of drawbar pull, Aldon® chocks are highly durable and reliable for rail safety needs.

A railcar wheel chock, or wheel block, is a device designed to prevent the movement of railcars by securing their wheels in place on the track. These chocks can be made of steel, urethane, or other materials and are essential for safety in rail yards, loading areas, and maintenance tracks. They help eliminate risks associated with runaway cars and unintended motion during operations.
