CR Manufacturing can custom build a complete grain truck probe system designed to safely increase your speed and efficiency. Grain truck probes can be installed on your scale or remotely for improved truck staging for country elevators, livestock feeders, food plants, feed mills, grain terminals, ethanol plants, flour mills, unit train facilities. Grain sample lines can be underground or overhead.

Pneumatic Grain Sampling

Pneumatic Grain Sampling is the simplest, most accurate, and quickest method available for probing grain trucks.


Pneumatic stingers do not damage the grain from opening and closing the sample head doors.


Air flowing through the pneumatic stinger transports the grain sample.


As the grain truck probe is pushed down, the grain forced up inside the tip is caught in the air flow and drawn in to the sample catch box.


The amount of air flowing through the stinger is preset to a standard amount at the factory, but can be field adjusted if required, providing a very accurate and representative sample of the load.
