PURPOSE: To check a traverse carrier without using a crane car, etc., and improve the installation strength of a drier by building a frame for checking the traverse carrier over a building receiving a grain-treating device and the upper part of a drier installed outside the building.

CONSTITUTION: Grains are carried from a building 1 receiving a grain-treating device to the upper feeding port 4a of a drier 4 through a traverse carrier 7. A checking frame 70 for checking the traverse carrier is built over the upper part of the drier and the building to support the drier.
