Railroad Wheel Chocks

Why Use Wheel Chocks?

A gust of wind is enough to cause a 260,000 pound freight car to start rolling. Thanks to roller bearings, freight car wheels offer very little resistance to movement. In fact, the contact area of each wheel on the rail is smaller than the size of a dime. This is why moving heavy loads by rail is so efficient! But at the same time, all this mass, so easily moved, needs to be securely blocked while the car is being worked.

Loading freight cars increases the strain on the car brakes. Liquid pouring into a tank car or a forklift moving back and forth in a boxcar create dynamic forces which can overcome the holding power of the brakes.

Slack in mechanical car brakes can be enough to allow a wheel to move forward a few inches and dislodge a dock board or strain a hose line.

This why OSHA mandates the use of wheel chocks in addition to car brakes wherever rail cars are being worked.
