PROBLEM TO BE SOLVED: To provide a simple transportation device for an agricultural greenhouse to easily transport harvested crops, fertilizers, agricultural machines and implements and other materials. SOLUTION: A rotary shaft is rotatably extended along the direction of the ridge of the greenhouse on a beam placed at the ceiling of the greenhouse, and a rotation transmission device is attached to an end of the rotary shaft to enable the change of the position of the rotary shaft by rolling the shaft toward the opening of the greenhouse. A rail extending in the direction of the rotary shaft is almost horizontally suspended from the rotary shaft with a plurality of suspending members having a structure to allow the rolling of the rotary shaft. A container, etc., suspended from a trolley traveling on the rail is transported in the directions of the ridge and width of the greenhouse. COPYRIGHT: (C)2004,JPO
