Abstract: This disclosure relates to a truck for transporting concentrated loads, particularly chicks, requiring air circulation. The truck includes a body that forms a load space, and equipment for circulating and treating air in the load space. A floor cavity is formed at the bottom of the load space and a ceiling cavity is formed at the top of the load space. In an instance where chicks are transported, the chicks are placed in chick boxes which are stacked in rows in the load space. The stacks are separated and stabilized by spacers and support ducts. The support ducts are connected to the floor and form ducts which conduct air upwardly from the floor cavity. The ducts have air openings formed therein at spaced intervals, and the circulating air moves out of the ducts and directly into the boxes.

Abstract: This disclosure deals with a truck including a vertically movable van and a lift mechanism for raising or lowering the van. The lift mechanism includes two arms pivotally connected in a scissors configuration. The arms are also connected to the truck frame and to the frame of the van in a manner to raise or lower the van as the scissors arms are spread or closed. An extensible power unit is connected between the two arms and is operable to spread or close the arms in order to raise or lower the van. Improved reinforcements are placed on the truck frame to provide the necessary strength.
