Frequently Asked Questions

Why use rail chocks?

A gust of wind is enough to cause a 285,000-pound freight car to start rolling. Thanks, in part to roller bearings, freight car wheels offer very little resistance to movement. 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.

Why use urethane wheel chocks?

For those needing a spark-proof chock when loading or unloading tank cars and freight cars, where a spark from a steel wheel chock could ignite dust or fumes, urethane wheel chocks are the answer. Urethane combines excellent resistance to loads with the ability to compress to half its thickness and then spring back to its original shape. Resilient enough for a locomotive to pull the car over the chock without derailing.

Should wheel chocks be used with car brakes?

Wheel chocks should be used in addition to car brakes whenever railcars are being worked. One type of chock, however, does not fit every situation. Contact our on-site sales engineers to guide you to the correct chock to use for your application.
