Heavy Duty Wheel Chocks
Built with the same proven design as the standard wheel chocks, Aldon’s “Whack ‘Em” heavy-duty Duty Wheel Chocks offer enhanced durability for the toughest railcar loading and unloading conditions.
In certain situations, such as when working with tank cars, wheel chocks with steel spurs may become lodged under the wheel. “Whack ’Em” Chocks are designed to handle this challenge. Featuring reinforced steel handles, these chocks can withstand hammer blows or forceful sideways pulls to free them quickly and efficiently, ensuring uninterrupted operations.

Spark-Proof Urethane Heavy-Duty Wheel Chock
Designed for one-direction chocking of tank cars and freight cars during the loading or unloading of hazardous materials, these urethane wheel chocks provide a safer alternative to steel chocks, eliminating the risk of sparks that could ignite dust or fumes.
Often called the “miracle material,” urethane offers exceptional load resistance while maintaining flexibility. It can compress to half its thickness under pressure and then spring back to its original shape, ensuring long-term durability. Unlike traditional materials, urethane resists corrosion, chemicals, and harsh environmental conditions, making it a reliable choice for demanding rail yard operations.
Features
- Available in two versions: Exposed rail or flush rail.
- Easy-grip design: Handles sit 1-1/2” above pavement when installed on flush rail.
- Optimized height: Stands 4” above the rail, ideal for chocking locomotives.
- Supports wheel diameters from 26″ – 44″
Urethane Heavy-Duty Double Wheel Chock

Steel chocks from Aldon have featured replaceable spurs which bite into the rail to give the chocks extra holding power.. When the spur dulls from use, remove the spur and turn it to a new edge. Extend the life of your wheel chocks by turning the spurs three times … then order new spurs instead of new chocks!

Frequently Asked Questions
Railcar chocks are essential safety devices that prevent unintended movement during loading, unloading, and maintenance operations. They help protect workers by securing railcars in place, reducing the risk of accidents caused by unexpected movement, especially when brakes are released for servicing. OSHA regulations require their use in many rail yard and repair facility operations.
Urethane wheel chocks provide a spark-proof solution during the loading or unloading of hazardous materials. These urethane wheel chocks provide a safer alternative to steel chocks, eliminating the risk of sparks that could ignite dust or fumes.
Yes. Flush mount rails are level with the ground, while exposed rails sit above the surface. Each requires a specific type of railcar chock to ensure proper grip and stability—using the wrong type may reduce holding power and compromise safety.
Steel railcar chocks were successfully tested at the Association of American Railroads’ testing facility at Pueblo, Colorado, to withstand more than 25,000 lbs of drawbar pull. That’s roughly 32% of a typical SD-40 freight locomotive drawbar pull.
CAUTIONS
- For use on railroad car or locomotive wheels 28″-44″. Do not use on smaller or larger diameter or on other types of wheels.
- For rail sizes 75 to 141 lbs./yd.
- Set brake before installing chock. Chock alone may not hold car in place.
- Use 2 chocks per car being chocked.
- DO NOT install chocks while car is moving.
- Rail surface must be clean. Do not install this product on oily or greasy rail – product may slip.
- Spurs are important in holding chock to rail. Rotate spur when edge becomes dull. Replace spurs when necessary. Dull or missing spurs may cause chocks to slip.
- Do not use chocks on grades. If your track has a dip or a hollow, extra care must be taken to secure car.
- Chocks may not hold if rail car is lifted up at one end.
- Excessive vibration may cause a chock to slip.
- Keep fingers and hands away from car wheel. Watch your head!
- On double chocks, always use tarp strap (supplied with chocks) to draw chocks tight.
