Abstract
The present invention relates to a tray for carrying a plurality of pallets loaded with several concrete blocks. The tray is a rectangular frame defining an upper surface, front and rear ends and upwardly-projecting flanges at both front and rear ends. The tray is adapted to receive the loaded pallets on its upper surface between the flanges. The invention further relates to a system adapted to carry the loaded tray through a block curing kiln. The kiln is composed of a plurality of longitudinal cells, as is already known, and the pallet-loaded trays are inserted in a consecutive linear abutment fashion in the cells. The relatively high flanges of each tray thus abut on one another, which prevents the overlapping of the trays, and thus prevents the damaging in this way of the concrete blocks. The system for carrying the concrete blocks includes a kiln, a tray loader for loading the pallets on the trays and a tray stripper for unloading them, an elevator-pusher for loading the trays in the kiln and an elevator-puller for unloading them, and a pallet stripper. The system further includes a pallet conveyor for conveying the pallets sequentially from the tray stripper to the pallet str…
