Railcar Movers

Move a railcar short distances easily and economically—these movers grip the rail as you push downward on the handle for the leverage needed to move the car. They have contact points that adjust to the railcar wheel for full contact over the entire length of the stroke.

Railcar Derailers

Secure the clamp on this derailer to a rail head to protect people, buildings, and other rail cars from uncontrolled car movements during loading, unloading, and servicing. Derailer is for temporary installation and operates by lifting the railcar's wheel and dropping it clear of the rail. It provides derailment in both directions. The clamp and flag can be locked in position with a padlock (not included).

Railcar Wheel Chocks

Single Chock with Red/White Flag

Double Chock

Double Chock with Red/White Flag

Exposed Rail

Paved Rail

Chock the wheels on stationary railcars to keep them from moving during loading, unloading, and servicing. Chocks install quickly, without tools.

A flag indicates that chocks are in use.

Single chocks prevent forward motion.

Double chocks prevent forward and backward motion. They are connected by a chain; a rubber strap attaches to the chain and draws the chocks together.
